TL;DR
Getting more product reviews starts with knowing where you need them to appear and whether you control the customer relationship. For brands selling through their own ecommerce site, automated post-purchase emails are table stakes. For UK FMCG brands selling through Tesco, Sainsbury’s, Ocado, Boots, or Amazon, the problem is harder because you rarely own the checkout data. The fastest compliant route for retailer product pages is targeted sampling or managed shopper advocacy, combined with always-on review velocity to keep reviews recent. Every method carries different cost, speed, and compliance tradeoffs, and UK law now treats concealed incentivised reviews as a banned practice.
Reviews influence whether a shopper clicks “add to basket” or scrolls past. PowerReviews found a 120.3% conversion lift when shoppers interact with ratings and reviews, based on analysis of more than 4.5 billion visits across 1.5 million product pages. source That figure alone explains why every brand wants more product reviews.
But “get more reviews” is not a single problem. It is several problems wearing the same label. A DTC brand on Shopify asking for reviews after checkout faces a completely different challenge than a food brand trying to build review coverage across Tesco, Ocado, and Holland & Barrett product pages. The right answer depends on where the review needs to appear, how fast you need it, what UK compliance rules apply, and whether you actually control the customer journey.
Most guides on this topic assume you own the checkout. This one does not make that assumption. It covers 12 practical, compliant methods for generating product reviews, with honest tradeoffs for each, and specific guidance for UK FMCG brands selling through retailers.
Why Product Reviews Matter More Than Ever
Three forces are raising the stakes.
Shoppers rely on reviews more than ever. Bazaarvoice’s 2025 research found that 100% of 2,500 surveyed consumers considered online reviews important when buying a new product, while 62% said a mix of positive and negative reviews actually makes reviews more trustworthy. source For grocery specifically, PowerReviews found that 83% of shoppers buying grocery and CPG products online are more likely to try a product they have never bought before if it has reviews from other customers. source Reviews are doing the job that in-store sampling and shelf-talkers used to do.
Review recency matters as much as volume. PowerReviews found that 97% of consumers consider review recency at least somewhat important, and 38% will not buy a product if the only reviews are three months old or older. source A launch spike of 50 reviews that ages out is worth less than a steady trickle of 5 fresh reviews per month. This is a critical insight for brands that treat reviews as a one-off project.
AI-powered shopping tools feed on review content. Bazaarvoice reports that almost one in four consumers have used a generative AI tool to search for a product, rising to 41% among 18 to 34 year olds. source Authentic ratings and reviews help feed these AI-driven product recommendations. If your product has no reviews, it has nothing for AI tools to summarise.
The connection between reviews and sales is not just about persuasion. CommerceIQ argues that strong ratings and reviews improve rate of sale, which then improves retailer search visibility and shelf priority. source For FMCG brands, reviews feed a flywheel: more reviews lead to higher trust, higher conversion, better rate of sale, better retailer search ranking, more traffic, more sales, and more review opportunities. Understanding the psychology of trust in shopping environments explains why this cycle is so powerful.
First, Diagnose Your Review Gap
Before spending money on review generation, figure out where you actually have a problem. Not every SKU needs the same treatment.
Map these dimensions for each product and retailer:
- Review count per SKU per retailer
- Average star rating per SKU
- Review recency: date of latest review and number of reviews in the last 30, 60, and 90 days
- Review quality: average length, specificity, photos or videos
- Retailer coverage: Tesco vs Sainsbury’s vs Ocado vs Boots vs Amazon
- Competitor benchmarks: how many reviews do comparable products in the category carry?
- Complaint themes: what are reviewers actually saying?
CommerceIQ recommends starting with category benchmarks: average review count and average rating by category, then deciding priorities. If the rating is below par, analyse the feedback. If review count is below par, generate more reviews. source
Review health is not static. A LinkedIn post from CheckoutSmart argues that UK grocery review exposure can change materially within three months as top visible reviews age out. source A product that looked healthy in January can look bare by April.
PowerReviews found that 45% of consumers say a product needs at least 1 to 25 reviews for them to feel comfortable purchasing. source Products sitting at zero or single-digit reviews are missing the credibility threshold that shoppers need to convert. Prioritise those SKUs first.
At-a-Glance Comparison: Review Generation Methods
| Method | Typical cost | Speed | Best for | Retailer PDP impact | Compliance risk | Main limitation |
|---|---|---|---|---|---|---|
| Post-purchase email/SMS | Low (app/email costs) | Medium | DTC and owned ecommerce | Low unless reviews syndicate | Low-medium | Needs customer email/order data |
| QR codes and inserts | Low (print cost) | Slow-medium | Physical products, repeat buyers | Medium if QR links to retailer page | Medium on some platforms | Low response rate; must be neutral |
| Incentives and rewards | Cost of reward | Fast | Owned channels and permitted retailers | Varies by platform | High if undisclosed or platform bans them | Can reduce quality and create bias |
| Product sampling | Product COGS + fulfilment + service fee | Fast | NPD, reformulations, low-review SKUs | High if reviews land on retailer PDP | Medium-high | Must disclose; avoid positive-review pressure |
| Managed shopper advocacy | Bespoke/pay per review | Fast | UK FMCG retailer PDPs | High | Medium if not managed carefully | Reviews appear only on the retailer where shopper bought |
| Amazon Vine | Programme fee + free units | Fast-medium | Amazon launches | Amazon only | Low within Amazon rules | Reviews not guaranteed; Amazon only |
| Review syndication | Enterprise/custom | Medium | Brands with reviews to distribute | High across supported network | Medium | Expensive; does not create reviews alone |
| Prompt-based review requests | Free (copy work) | Medium | Brands getting thin “Great product” reviews | Indirect | Low | Requires review form configuration |
| Photo/video review requests | App/platform feature cost | Medium | Visual product categories | Indirect | Low | More friction; more moderation |
| Review analytics/audits | Internal or SaaS | Immediate insight | Prioritisation | Indirect | Low | Does not generate reviews by itself |
Now, the 12 methods in detail.
12 Practical Ways to Get More Product Reviews
1. Audit your review gaps before running any campaign
Best for: FMCG brands with multiple SKUs across multiple retailers, especially before NPD launches, range reviews, or retail media campaigns.
The brands that win at reviews do not spray effort everywhere. They triage. Create a simple audit spreadsheet:
- SKU name
- Retailer and PDP URL
- Current review count
- Average rating
- Date of most recent review
- Number of reviews in the last 90 days
- Competitor review count in the same category
- Main complaint themes
- Priority level (high, medium, low)
This takes a few hours and saves thousands in wasted sampling or advocacy spend. The point is to identify which SKUs and which retailer PDPs need reviews most urgently, not to generate reviews on products that already have strong coverage.
Tradeoffs:
- An audit generates zero reviews by itself.
- It does prevent you from investing in the wrong places.
- Manual audits do not scale well past 50 to 100 SKUs without tooling.
2. Fix the product experience and PDP basics before asking
Best for: Products with low star ratings, confused reviews, or negative sentiment that would be amplified by more volume.
More reviews amplify the truth. Make sure the truth helps you.
Before asking for reviews, check:
- Is the product title accurate and clear?
- Do the images match the actual product?
- Are flavour, size, dosage, and ingredient claims precise?
- Is the packaging creating unmet expectations?
- Are usage instructions and FAQs available?
- For reformulations or pack changes, does the PDP explain what changed?
Amazon seller discussions on Reddit repeatedly emphasise that the product experience comes first. One thread’s consensus is that the best lever is making the product worth reviewing and improving listing quality so shoppers are not surprised after purchase. source
Tradeoffs:
- Slower than running a campaign.
- Absolutely necessary if ratings are weak. Generating more reviews for a flawed product just accelerates the damage.
- PDP fixes on retailer sites depend on retailer content processes, which can be slow.
Poor in-store execution and availability issues create the same problem. If shoppers cannot find the product, find it damaged, or find it incorrectly priced, reviews will reflect that.
3. Automate post-purchase review requests where you own the customer
Best for: DTC ecommerce brands using Shopify, WooCommerce, BigCommerce, or any platform with first-party customer email data.
This is table stakes for owned channels. Set up automated flows that:
- Trigger after delivery confirmation, not after order placement
- Wait 7 to 14 days for the customer to actually use the product
- Include the product name and image
- Link directly to the review form
- Suppress requests for refunded orders, complaints, or failed deliveries
- Send one follow-up reminder, unless the platform allows more
Bazaarvoice reports that review request emails can increase review content by 4 to 9x, and follow-up emails can increase volume by up to 50%. source
Pricing:
- Judge.me offers a free plan and a $15/month plan with unlimited reviews, photo/video reviews, and review requests. source
- Yotpo’s free plan covers businesses up to 50 orders per month, with Growth and Prime plans covering higher volumes. source
- Enterprise platforms like Bazaarvoice use custom pricing.
Practitioner insight: Practitioners on Reddit report that timing is the most common mistake. Brands ask before delivery or before usage. They recommend adjusting the delay based on product type: shorter for everyday consumables, longer for products where results take time. They also warn that if review emails land in Gmail’s Promotions tab or spam, the entire strategy fails silently. source
Tradeoffs:
- Does not help when the retailer owns the checkout and customer relationship.
- Works for DTC channels, not UK grocery retailer PDPs.
- Open-ended forms tend to produce short, low-effort reviews.
4. Ask at the right moment with specific prompts
Best for: Brands getting too many thin reviews like “Good” or “Love it” and not enough detail that helps future shoppers decide.
Generic review forms produce generic reviews. Specific prompts give customers a mental framework and produce far more useful content.
Instead of “Leave a review,” try:
- What made you try this product?
- How was the flavour, texture, or scent?
- How did you use it?
- Who would you recommend it to?
- How does it compare with what you usually buy?
- Would you buy it again?
Yotpo notes that 56% of its reviews come from mobile devices, so prompts need to work on small screens. source
One Reddit ecommerce discussion found that detailed reviews come from making it easier to write more, not asking shoppers to “try harder.” Users recommended simple prompts, product images, and a form that combines individual answers into a single review. source
Prompt examples by category:
Food and drink: How was the flavour? Was the texture what you expected? How did you serve it? Would you buy it again?
Beauty and personal care: What is your skin or hair type? How long did you use it? What results did you notice? Would you repurchase?
Household: What did you use it for? Did it solve the problem? Was it easy to use?
Health and wellness: Why did you try it? Was it easy to take or use? Did the packaging and instructions make sense?
Tradeoffs:
- Too many questions increase friction and reduce completion rates.
- Overly leading prompts can bias reviews and create compliance issues.
- Prompt for usefulness, not positivity.
5. Use incentives carefully, and only where the platform allows them
Best for: Owned channels and retailers that permit incentivised reviews with clear disclosure.
A compliant incentive should be:
- Offered for an honest review, not a positive review
- Clearly disclosed on the review itself
- Available regardless of the star rating given
- Not conditional on changing, removing, or upgrading a review
- Not restricted to only satisfied customers
- Aligned with the specific retailer or platform’s policy
UK compliance context: The UK’s fake-review rules came into force on 6 April 2025 under the Digital Markets, Competition and Consumers Act. The CMA now treats fake reviews and concealed incentivised reviews as banned practices. source The key risk is not offering incentives. It is hiding that the review was incentivised. source
ASA/CAP guidance confirms that incentivising genuine, unbiased reviews can be acceptable, but directly incentivising positive reviews is likely to be problematic. Brands must not interfere with reviewers’ ability to leave negative feedback. source
Platform rules differ significantly:
- Tesco allows incentivised reviews only if incentives are clearly and prominently disclosed and are not contingent on a positive rating or review. source
- Amazon UK prohibits compensated reviews except through Amazon Vine. source
- Trustpilot bans incentivised reviews entirely, including discounts, promo codes, prize entries, refunds, and freebies. source
Reddit users say incentives can increase review volume but often reduce review quality because some people review only for the discount. One practitioner noted that photo incentives tend to create better content than generic discount incentives. source
For a deeper look at what UK FMCG brands can and cannot do, read the full product review campaigns UK FMCG compliance guide.
Tradeoffs:
- Highest compliance risk if mishandled.
- May produce low-quality, low-effort reviews.
- Some platforms ban incentives entirely, so what works on Tesco will get you removed from Trustpilot.
6. Run product sampling campaigns with matched shoppers
Best for: NPD launches, reformulations, seasonal products, and any SKU with naturally low organic review rates.
Sampling works when it is targeted. Sending free product to random people produces random results. The goal is to reach shoppers who match the product’s target audience, give them enough time to use it properly, and ask for honest public feedback with clear disclosure.
A compliant sampling campaign should:
- Match shoppers to the real target audience (demographics, category interest, dietary needs)
- Require genuine product use
- Use receipt, order, or retailer verification where possible
- Ask for honest feedback regardless of sentiment
- Disclose that the product was received free or at a discount
- Give enough usage time before requesting the review
- Collect internal feedback alongside public reviews
Pricing:
- Product COGS per unit
- Fulfilment or cashback reimbursement
- Platform or provider fee
- Moderation and reporting
- Typical total cost varies widely depending on product value and campaign size
Tradeoffs:
- If targeting is poor, samples reach people who would never buy the product.
- If the incentive is hidden, the campaign creates legal and reputational risk.
- If reviews are one-off, recency decays within months.
- Not all reviews will pass retailer moderation.
Sampling is not “free product for five stars.” It is targeted trial, honest review, disclosure, and verification.
7. Use managed shopper advocacy for retailer PDPs
Best for: UK FMCG brands that need verified purchase reviews on Tesco, Sainsbury’s, Ocado, Boots, Holland & Barrett, Amazon, or other retailer product pages where they do not control checkout data.
This is the hardest version of the review problem. When shoppers buy from a grocer, the brand typically has no post-purchase email, no order ID, and no ability to trigger a review request. The retailer owns the entire customer relationship.
Managed shopper advocacy solves this by recruiting real UK shoppers to buy, try, and review products on the specific retailer’s website.
Brand Allies is a managed-service shopper advocacy platform built for this exact scenario. It uses a community of 250,000 UK shoppers to generate verified purchase reviews on retailer PDPs. The service covers Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, Iceland, Holland & Barrett, Amazon, TikTok Shop, and other relevant channels. The pricing model is pay per verified review, and the service is bespoke-priced.
Because the shoppers are real UK residents making genuine purchases through the retailer’s normal checkout process, the reviews carry verified purchase status on platforms that support it.
Key features:
- UK-resident shopper community
- Retailer-specific review generation (reviews appear on the PDP where the purchase happened)
- Buy, try, and review workflow
- Managed service rather than self-serve SaaS
- Can combine online reviews with in-store compliance checks and store execution audits
Amazon and ecommerce forum discussions highlight the frustration brands face when relying on organic reviews alone. Sellers commonly cite organic review rates of just 1 to 5 per 100 orders. source For FMCG products with lower engagement, rates can be even lower. The gap between organic review velocity and the volume needed to reach credibility thresholds is what makes a managed approach necessary.
Tradeoffs:
- Reviews appear only on the retailer where the shopper purchased. No cross-retailer syndication.
- Reviews must still be authentic, disclosed where required, and accepted by retailer moderation. Some reviews will be rejected.
- Best results come from ongoing campaigns, not one-off spikes.
If you sell through UK grocers and marketplaces, post-purchase email flows are only part of the answer. A managed shopper advocacy campaign gives you a way to recruit UK shoppers, drive verified purchase behaviour, and generate retailer-specific reviews without waiting for organic rates to catch up. Explore how Brand Allies’ review service works.
8. Use retailer and marketplace native programmes
Best for: Amazon product launches and brands eligible for marketplace-run review programmes.
Amazon Vine is the most well-known example. Amazon invites trusted reviewers (called Vine Voices) to receive products for free and leave reviews. The reviews are labelled as Vine reviews of free products. Sellers cannot control or influence the review content.
Amazon Vine pricing (from Seller Central forum discussions):
- Free tier: up to 2 Vine reviews
- $75 tier: up to 10 reviews
- $200 tier: up to 30 reviews
- Plus the cost of free product units and FBA fees
Practitioner insight: Seller Central forum discussions repeatedly show sellers frustrated that Vine reviewers are not required to leave a review for every product they claim. One Amazon community reply states that over 80% of Vine units ordered are reviewed within 90 days at programme level, but individual sellers may see much lower completion rates. source
Tradeoffs:
- Amazon only. Does nothing for Tesco, Sainsbury’s, Ocado, or Boots.
- Reviews can be critical. Free product does not guarantee positive sentiment.
- Sellers cannot pressure reviewers.
- Review completion is not guaranteed.
Use Vine if Amazon is the priority. Do not mistake it for a UK grocery review strategy.
9. Use review syndication platforms when distribution is the bottleneck
Best for: Brands that already have a strong review base on their own site and need to distribute those reviews across retailer partners.
Platforms such as Bazaarvoice and PowerReviews help brands collect, moderate, display, and syndicate review content to retail partners within their network. Bazaarvoice says that one brand, Petmate, syndicated more than 8,500 reviews to more than 50 retailers. source
Pricing:
- Typically enterprise and custom-priced.
- G2 reviewers describe Bazaarvoice as expensive for many brands. source
- Gartner describes Bazaarvoice pricing as subscription-based and tailored by content volume, features, domains, and regions. source
Practitioner insight: Reddit users in an ecommerce thread question whether Bazaarvoice syndication is worth it if the brand is not already collecting enough reviews to distribute. A separate BigSEO thread warns about technical crawl and indexation issues from review pagination if the implementation is poorly handled. source
Tradeoffs:
- Expensive, often with annual contracts.
- Syndication moves reviews. It does not create them.
- Retailer network coverage varies. Not all UK grocers participate in the same syndication networks.
- Technical implementation matters and can go wrong.
Syndication is valuable when you have a distribution problem. If you have a creation problem (not enough reviews to begin with), syndication alone will not solve it.
10. Add QR codes and neutral review prompts to packaging
Best for: Physical products, repeat-purchase FMCG, and DTC orders where the brand controls packaging.
A QR code on the packaging or an insert can reduce friction by linking shoppers directly to a review form. The key word is “neutral.” The prompt should say “Tell us what you thought,” not “Leave us a 5-star review.”
QR codes can link to:
- The product’s retailer PDP review section
- An owned review collection form
- Product usage instructions followed by a review request
Practitioners on Reddit mention QR codes on receipts, packaging, and checkout materials as a simple way to make reviewing easier. source Shopify recommends making it easy for customers to choose where they review and using direct links. source The same principle applies to QR codes.
Tradeoffs:
- Low response rates unless the product experience is strong.
- Amazon has strict rules around inserts and review solicitation.
- Must avoid routing unhappy customers away from public review channels. That is review gating, and it is problematic under both UK law and most platform rules.
QR codes are friction reducers, not review engines. They work best as part of a wider strategy.
11. Ask for photo and video reviews where visual proof matters
Best for: Beauty, food preparation, pet products, baby products, home care, and any category where seeing the product in use builds confidence.
Visual reviews show texture, colour, size, packaging, serving ideas, and real-life usage context. PowerReviews’ CPG analysis found that the average CPG product had 30.3% media coverage in its reviews, suggesting there is room for most brands to increase visual content. source
Reddit ecommerce users note that photo incentives often produce better content than generic discount incentives, though any incentive can also attract low-effort submissions from people who are only there for the reward. source
Tradeoffs:
- More moderation burden.
- More privacy and permissions work.
- Higher friction than a simple star rating.
- Not every retailer displays image or video reviews consistently.
Request photo and video reviews selectively for SKUs where visual context genuinely helps shoppers decide.
12. Maintain review recency with always-on review velocity
Best for: Mature FMCG SKUs with ageing reviews, reformulations, packaging changes, seasonal products, and brands preparing for promotions or range reviews.
A review spike is a launch tactic. Review velocity is a growth system.
PowerReviews found that 64% of consumers are more likely to buy a product with fewer recent reviews than one with more stale reviews. source A Reddit shopping thread advises consumers to sort reviews by “Most Recent” because product quality and seller behaviour change over time source, which confirms that recency is not a vanity metric.
Treat review freshness as an ongoing KPI:
- Set monthly or quarterly review targets per SKU per retailer
- Refresh reviews after formulation, packaging, or price changes
- Monitor the age of the top visible reviews on each PDP
- Track competitor review velocity
- Maintain an always-on review health dashboard
For FMCG brands, this usually means combining owned-channel review requests with periodic managed advocacy or sampling campaigns. The owned channel handles DTC flow. The managed campaigns handle retailer PDPs.
Tradeoffs:
- Requires ongoing budget, not a one-off spend.
- Harder to sell internally than a launch campaign.
- Needs clear operational ownership.
How to Turn Review Feedback Into Product and Retail Fixes
Getting more product reviews is not just about accumulating stars. Reviews are a feedback channel. Use them.
Analyse reviews to identify:
- Recurring taste, flavour, or texture complaints
- Packaging confusion or damage
- Misleading imagery or claims
- Missing usage instructions
- Price and value objections
- Out-of-stock or substitution problems
- Store execution issues
Bazaarvoice found that 62% of consumers say mixed positive and negative feedback makes reviews more trustworthy. source CommerceIQ adds that shopper reviews can inform product development and marketing by surfacing quality issues, unmet needs, and category whitespace. source
Amazon Vine UK discussions on Reddit note that balanced 3-star reviews can be more useful than generic 5-star or 1-star reviews because they explain what is good and bad about a product. source
The goal is not to collect praise. The goal is to reduce buyer doubt and improve the product.
Which Review-Generation Method Fits Your Situation?
If you own the checkout: Automate post-purchase email and SMS requests. Add QR codes to packaging. Use review apps. This is cheap and effective for DTC.
If you sell through Amazon: Use Amazon Vine for launches. Use Amazon’s built-in review request tools. Accept that organic rates will be low (1 to 5%).
If you sell through UK grocers (Tesco, Sainsbury’s, Ocado, Boots, Holland & Barrett): Post-purchase emails will not work because you do not own the customer data. Use managed shopper advocacy or retailer-compatible sampling to route verified shoppers to the right retailer PDP.
If you already have many reviews on your own site but weak retailer coverage: Consider syndication through platforms like Bazaarvoice or PowerReviews to distribute existing reviews.
If your star ratings are weak: Fix the product and PDP first. Do not generate more reviews that amplify existing problems.
If your reviews are old: Run recency-focused campaigns. A steady flow beats a stale pile.
For brands that need reviews across multiple UK retailers and do not control the checkout, a managed shopper advocacy service is usually the most direct route.
What Not to Do
UK compliance is now stricter. Since 6 April 2025, the CMA has stronger direct enforcement powers under the Digital Markets, Competition and Consumers Act. source
Here is the compliance checklist:
- Do not buy fake reviews. Reviews must come from real people with genuine product experience.
- Do not write reviews yourself or ask staff, agencies, friends, or family to pose as normal customers.
- Do not offer payment for positive reviews. Incentives for honest reviews (where the platform allows) must be neutral and disclosed.
- Do not hide incentives. Concealed incentivised reviews are a banned practice under UK law. source
- Do not suppress negative reviews. Do not filter, gate, or pressure reviewers into changing or removing criticism.
- Do not ask only happy customers. Review requests must go to all eligible customers, not just the ones you think will leave good feedback.
- Do not copy reviews across platforms unless the retailer and syndication provider explicitly allow it.
- Do not use a one-off spike and ignore recency. Reviews age. Build a system.
- Do not ignore poor in-store execution. If the product is unavailable, damaged, or incorrectly priced, generating reviews will not fix the underlying problem. Consider combining review campaigns with retail promotions and activations to support sell-through.
Keep records of campaign terms, reviewer instructions, disclosures, and moderation outcomes. If the CMA or a retailer asks, you need to show your working.
The Review Velocity Flywheel
The best-performing FMCG brands treat reviews as part of an operating system, not a one-off project. Here is how the flywheel works:
- Better PDP and availability creates a foundation.
- More buyers and trials create review opportunities.
- More verified reviews build trust and credibility.
- Higher trust drives higher conversion.
- Better rate of sale improves retailer search ranking and shelf priority.
- More visibility drives more traffic and sales.
- More sales create more review opportunities.
- Repeat.
Break any link in that chain and the system stalls. A product with great reviews but poor availability loses sales. A product with strong availability but zero reviews loses conversions. This is why the brands that combine review generation with in-store compliance and execution checks tend to outperform those treating each problem in isolation.
FAQs
How do I get more product reviews quickly?
The fastest compliant methods are product sampling with matched shoppers and managed shopper advocacy campaigns, because they actively recruit reviewers rather than waiting for organic behaviour. Amazon Vine is fast for Amazon specifically. Post-purchase email automation works if you already have customer data but depends on open rates and timing.
Can I offer free products for reviews in the UK?
Yes, but with strict conditions. The review must be honest (not required to be positive), the incentive must be clearly disclosed, and the platform must allow it. Tesco allows disclosed incentivised reviews. Amazon bans all compensated reviews except through Vine. Trustpilot bans incentivised reviews entirely.
Are incentivised reviews legal in the UK?
Incentivised reviews are not illegal by default. Concealed incentivised reviews are a banned practice under the Digital Markets, Competition and Consumers Act, which took effect 6 April 2025. The ASA says incentivising genuine, unbiased reviews can be acceptable, but incentivising positive reviews is problematic.
How do I get product reviews on retailer websites like Tesco or Sainsbury’s?
You cannot send post-purchase emails to customers who bought through a retailer because you do not own that data. Options include managed shopper advocacy (where real shoppers are recruited to buy, try, and review on the retailer’s site), retailer-compatible sampling campaigns, QR codes on packaging linking to the retailer PDP, and syndication of existing reviews where supported.
How many product reviews does a product need?
PowerReviews found that shoppers exposed to even 1 to 10 reviews are 52.2% more likely to convert than those exposed to none. Most research suggests that 20 to 30 reviews is a practical credibility threshold for many categories, though this varies. Recency matters as much as volume.
What is the difference between review seeding and fake reviews?
Review seeding means recruiting real people to try a product and share genuine feedback. Fake reviews are fabricated, written by people who have not used the product, or are paid to be positive. The line is drawn at authenticity, disclosure, and genuine experience. Seeding is legal when done compliantly. Fake reviews are banned.
Do negative reviews hurt sales?
Not as much as most brands fear. Bazaarvoice found that 62% of consumers say a mix of positive and negative reviews makes feedback more trustworthy. Products with only perfect 5-star reviews can actually seem less credible. The bigger risk is having no reviews at all.
What is the best way to get reviews for a new FMCG product launch?
Start with a review gap audit to identify priority SKUs and retailers. Fix the PDP basics. Run a managed shopper advocacy or sampling campaign targeting the retailers where you need coverage. Use Amazon Vine if Amazon is a priority. Set up ongoing review velocity targets so the launch reviews do not go stale. Check the Brand Allies FAQs for more detail on how managed campaigns work.
Getting more product reviews is not a one-off campaign. For FMCG brands, it is an operating system: keep products available, recruit the right shoppers, collect honest feedback, disclose incentives, refresh review recency, and use the feedback to improve both the PDP and the product. The brands that build this system outperform those still waiting for reviews to appear on their own.
If you are a UK FMCG brand that needs verified reviews on retailer product pages, book a demo with Brand Allies to see how managed shopper advocacy works across Tesco, Sainsbury’s, Ocado, Boots, Amazon, and other UK retailers.
