Sampling Campaign Survey Questions: Definition, Examples and FMCG Question Bank

TLDR: Sampling campaign survey questions are the screening, feedback, and review-readiness questions used before and after a product sampling campaign. They decide who receives a sample, which variant they get, what feedback the brand can trust, and whether the resulting reviews stay compliant. For UK FMCG brands, getting these questions right is the difference between useful shopper evidence and wasted stock.

What Are Sampling Campaign Survey Questions?

Sampling campaign survey questions are the questions used to qualify shoppers for a product sample, match them to the right product or variant, collect feedback after they try it, and measure whether the campaign produced useful results. Odore defines a product sample questionnaire as a structured survey used to gather feedback from people who have used or experienced a product.

These questions sit at two key moments in a campaign:

Before fulfilment (prequalification and screening): The brand asks questions to decide whether a shopper should receive a sample and which product to send.

After product use (post-trial feedback and review readiness): The brand asks questions to capture genuine experience, estimate purchase intent, and confirm the shopper is ready to leave an honest review.

One important clarification. The phrase “sampling” in survey methodology usually refers to how respondents are selected for a study. That is not what this article covers. Here, “sampling” means product sampling, where a brand gives shoppers a physical product to try.

For brands planning their first campaign, a sampling campaign brief template can help organise goals before writing survey questions.

Why Do Brands Use Survey Questions in Sampling Campaigns?

Product samples cost money. The brand pays for the product, distribution, campaign management, and follow-up. Sending samples to people who cannot use the product, do not buy the category, or have no access to the target retailer is waste.

Survey questions exist to prevent that waste and to turn free product distribution into commercial evidence.

Here is what good sampling campaign survey questions actually do:

Stop samples going to the wrong people. PowerReviews gives a useful example: a baby monitor sample should not go to all adults aged 30 to 40. The brand also needs to know whether the person has a young child.

Improve review completion rates. Bazaarvoice reports that in its experience, every 50 samples sent produces about 45 reviews. PowerReviews cites an 85% average review submission rate across its sampling campaigns. Those rates only hold when the right people receive the right product.

Connect trial to commercial outcomes. A sample alone proves nothing. The survey tells the brand whether the recipient would buy at full price, switch from a competitor, recommend to a friend, or leave a retailer review.

Protect compliance. In review-led campaigns, the survey must not pressure positive sentiment. More on that below.

For brands trying to estimate product trial campaign costs, a simple formula helps: divide target reviews by expected review submission rate. If you want 100 reviews and expect an 80% submission rate, you need roughly 125 samples.

The Five Jobs Every Sampling Survey Question Should Do

Most weak surveys over-index on “what did you think?” questions and under-index on everything else. A better approach: every question should do one of five jobs. If it does not change targeting, fulfilment, interpretation, or follow-up, cut it.

Job	What it decides	Example
Screen	Should this shopper receive a sample?	“How often do you buy products in this category?”
Match	Which product, flavour, shade, or format is right?	“Which of these flavours would you be most likely to buy?”
Verify	Did they receive, open, and properly use the product?	“How many times have you used the product since receiving it?”
Learn	What did the shopper think and why?	“What, if anything, would you change about the product?”
Measure	Did the campaign create a commercial signal?	“How likely are you to buy this product at full price?”

This framework keeps surveys short and purposeful. Every question earns its place.

Prequalification Questions to Ask Before Sending Samples

Prequalification is where sampling campaign survey questions have the biggest financial impact. Ask the wrong screening questions (or none at all) and you send expensive product to people who will never buy it.

Sampl warns that broad, unscreened sampling can attract people looking for free goods with no intention of purchasing.

Category usage

These questions identify real category buyers, not just people who want free stuff.

• “How often do you buy products in this category?” (Weekly / 2-3 times a month / Monthly / Less often / Never)
• “Which brands in this category have you bought in the past three months?”
• “Where do you usually buy this type of product?” (Tesco / Sainsbury’s / Asda / Morrisons / Ocado / Boots / Holland & Barrett / Amazon / Other)

Product fit and safety

Not everyone can safely or meaningfully use every product.

• “Do you or anyone in your household have any of the following allergies or dietary restrictions?”
• “Do you have a dog in your household?”
• “What is your child’s age range?”
• “Do you have access to a freezer at home?”

Sampl gives practical examples: pet food campaigns should ask about pet ownership, skincare campaigns should ask about primary skin concerns, and wellness campaigns should screen for relevant health conditions.

Retailer and review eligibility

When the campaign depends on reviews appearing on specific retailer websites, these questions are essential.

• “Which of these retailer accounts do you have?”
• “Would you be able to buy this product from [retailer] within the next seven days if selected?”
• “Are you able to leave an honest review on the retailer website after trying the product?”

For brands building a new SKU review strategy, retailer access questions prevent the common problem of sending samples to shoppers who cannot actually review where the brand needs coverage.

Switching potential

The best sampling audiences are not always loyal brand buyers. Someone who buys the category but switches between brands may be more commercially valuable than someone who accepts every free product but never repurchases.

• “Which statement best describes you?” (I usually buy the same brand / I switch between a few brands / I often try new brands / I only buy on promotion)
• “What would most influence you to try a new product in this category?”

Consent and expectation-setting

Practitioners on Reddit report real frustration when campaign tasks are unclear. In an Influenster discussion, one user said they avoided campaigns with post-surveys because extra tasks appeared after they had already accepted. Others described multi-product boxes as “a lot of work” when several reviews or social posts were required.

Best practice: tell participants upfront.

• “If selected, are you willing to try the product and complete a short feedback survey?”
• “If selected, are you willing to leave an honest review after trying the product?”
• “Do you understand that your review should reflect your genuine experience, whether positive, neutral, or negative?”

Product-Matching Questions by FMCG Category

Sending the wrong variant creates irrelevant feedback. Someone who hates spicy food should not review the extra-hot flavour unless that is the explicit test. These questions prevent mismatches.

Food and drink

• “Which flavours would your household be most likely to try?”
• “Which spice level do you usually prefer?”
• “Which pack size would you normally buy?”
• “Which meals or occasions would you use this for?”

Beauty and personal care

• “Which skin type best describes you?”
• “Which skin concerns are you most interested in addressing?”
• “Which shade range best matches your usual product?”

Pet

• “What type of pet do you have?”
• “What is your pet’s age?”
• “Does your pet have any dietary restrictions?”
• “Which format do you normally buy: dry, wet, treats, or supplements?”

Household

• “Which surfaces or rooms would you use this product for?”
• “Which scent profile do you prefer?”
• “Do you use refillable, concentrated, or ready-to-use formats?”

Drawing from a shopper community that already provides household and preference data can reduce the number of matching questions needed.

Post-Trial Survey Questions to Ask After Product Use

Post-trial questions are where most brands start, but they work best when prequalification has already filtered the audience. Here are the question categories that matter.

Usage verification

Before asking opinions, confirm actual use.

• “Did you receive the product?”
• “Have you tried the product?”
• “How many times have you used or consumed it?”
• “Did you use it as directed on pack?”

Timing matters too. A Reddit user discussing campaign surveys noted that a 25-day wait before completing a food product survey could actually improve quality because people are more likely to use the product multiple times before answering. For beauty or skincare products, two to four weeks may be necessary for claims to become apparent.

Product experience

• “Overall, how satisfied were you with the product?”
• “How would you rate the taste / scent / texture / performance?”
• “What did you like most?”
• “What did you dislike, if anything?”
• “Did the product meet your expectations?”

Packaging and shelf communication

• “Was the packaging easy to understand?”
• “Which product benefit was clearest from the pack?”
• “Would the product stand out on shelf or online?”

These questions are particularly useful for NPD launches and pack redesigns.

Price and value

• “Before trying it, what price would you expect this product to cost?”
• “At its usual shelf price of £X, how likely would you be to buy it?”
• “Which statement best describes the value for money?” (Very good value / Fair value / Slightly expensive / Too expensive)

Purchase intent

Use a balanced five-point scale:

• Definitely would buy
• Probably would buy
• Might or might not buy
• Probably would not buy
• Definitely would not buy

Then follow up: “Would this replace something you currently buy?” and “Where would you expect to buy this product?”

Open-ended questions

Use sparingly. Two maximum in a short survey.

• “What, if anything, would stop you buying this product again?”
• “What would you tell a friend about this product?”

These often surface issues that closed questions miss entirely.

Review-Led Sampling Questions

Many sampling campaigns exist specifically to generate product reviews. This is where sampling campaign survey questions need the most care, because the line between useful prompting and biased pressure is thin.

Research from Northwestern University’s Spiegel Research Center found that products with five reviews have 270% greater purchase likelihood than products with no reviews. The same research found that purchase likelihood peaks around ratings of 4.0 to 4.7, not perfect 5.0 scores.

That finding matters. It means honest, balanced reviews are more credible and commercially effective than manufactured positivity.

Good review-readiness questions:

• “Have you used enough of the product to leave an honest review?”
• “Would you feel confident writing a review based on your experience?”
• “What would you want other shoppers to know before buying?”

Questions you should never ask:

• “Would you leave a five-star review?”
• “Would you write a positive review?”
• “Would you recommend this product?” (when framed as a condition for receiving the sample)

Shoppers notice when review pages are dominated by free-product recipients. On Sephora’s subreddit, one user complained that almost all reviews for a product appeared to be from people who received it free, and said they wanted to hear from someone who chose to spend their own money. Good survey design should encourage specific, experience-led reviews rather than generic praise.

For a deeper look at review compliance rules, especially CMA and ASA requirements, brands should treat disclosure as non-negotiable.

UK Compliance: What Brands Must Not Do

The CMA’s guidance on fake reviews is clear. Brands may incentivise customers to leave reviews, but two conditions must be met: consumers must be told the review was incentivised, and the review must reflect the reviewer’s genuine experience.

Banned practices include asking for five-star reviews in exchange for free products and reimbursing only after a positive review is submitted.

The ASA/CAP guidance adds that influencer-style content involving gifts or collaborations should be clearly and obviously identifiable, with a prominent upfront “Ad” label. Labels like “Gifted” or “Thanks to” are unlikely to be sufficiently clear on their own.

Do

• Ask for honest reviews
• Tell participants to disclose incentives
• Allow negative, neutral, and positive feedback
• Keep review sentiment independent from reward or future eligibility

Do not

• Ask for five-star reviews
• Reimburse only after a positive review
• Reject or penalise honest negative feedback
• Hide that a product was free, discounted, or incentivised
• Use wording that pressures favourable responses

How to Write Better Sampling Campaign Survey Questions

Ask one thing at a time

Bad: “How satisfied were you with the taste and packaging?”

Better: Split into two separate questions.

AAPOR recommends that survey questions be specific and about one concept at a time.

Use plain language

Bad: “How would you evaluate the organoleptic profile?”

Better: “How would you rate the taste, smell and texture?”

Avoid leading wording

Bad: “How much did you enjoy our delicious new product?”

Better: “How would you rate the product overall?”

Pew Research Center warns that even small wording differences can substantially affect the answers people give.

Put disqualifiers early

For FMCG, allergens, dietary restrictions, pet ownership, retailer access, and geographic eligibility should come before softer preference questions. This prevents brands collecting responses from people who should never have qualified.

Use balanced scales

Bad scale: Amazing / Good / Okay

Better scale: Very satisfied / Somewhat satisfied / Neither satisfied nor dissatisfied / Somewhat dissatisfied / Very dissatisfied

Balanced scales reduce the implicit pressure to answer positively.

Use skip logic

If someone has not tried the product, skip the product-rating questions and ask when they expect to try it. If someone would not buy again, ask why. Skip logic keeps surveys short and relevant, which improves completion rates.

Keep it short

Sampling industry practitioners say data and insights are becoming increasingly important, but brands often get customer acquisition wrong by trying to do too much at once. A pre-sample survey of 8 to 12 questions and a post-trial survey of 8 to 10 questions will cover most FMCG campaigns without exhausting participants.

Example Sampling Campaign Survey Template

Pre-sample survey (8-12 questions)

1. Country or region
2. Retailer access
3. Category purchase frequency
4. Current brands bought
5. Product-fit disqualifier (allergies, restrictions)
6. Household fit (pet, child, appliance)
7. Variant preference (flavour, shade, format)
8. Willingness to try within campaign timeline
9. Willingness to complete feedback survey
10. Honest-review acknowledgement

Post-trial survey (8-10 questions)

1. Did you receive the product?
2. Did you try it?
3. How many times did you use it?
4. Overall satisfaction (5-point scale)
5. Best feature (select from list)
6. Main issue or dislike (select or open text)
7. Packaging clarity
8. Purchase intent at full price (5-point scale)
9. Review-readiness confirmation
10. Open text: “What would you tell another shopper about this product?”

For brands running sampling alongside in-store activity, connecting survey questions with retail campaign verification can provide a fuller picture of campaign performance.

Common Mistakes to Avoid

Asking too many questions. Survey fatigue kills completion rates. Every question that does not change a decision should be cut.

Asking “interest” instead of behaviour. “Would you be interested in trying this?” is weaker than “How often do you buy this category?” Interest is cheap. Behaviour predicts repurchase.

Forgetting allergies and restrictions. Sending a nut-based snack to someone with a nut allergy is not just wasteful, it is dangerous.

Asking for reviews before enough usage. Skincare needs weeks. A snack needs a single sitting. Match the review request to realistic usage windows.

Hiding campaign tasks. If the campaign requires a survey, a review, photos, and a social post, say so upfront. Hidden workload creates resentment and incomplete data.

Confusing “positive review” with “honest review.” This is both a compliance risk and a credibility risk. Brands that chase star ratings instead of genuine feedback end up with review pages that shoppers do not trust.

Treating all categories the same. Food, beauty, pet, and household products have different disqualifiers, different usage timelines, and different feedback needs. A generic “what did you think?” question is not enough.

Measuring satisfaction but not purchase intent. Satisfaction tells you whether someone liked the free product. Purchase intent tells you whether they would pay for it. Both matter, but the second one drives commercial decisions.

Brands exploring different sampling, cashback, and rebate approaches should design survey questions that reflect the specific mechanic being used.

How Survey Questions Support Review-Led FMCG Campaigns

In a review-led FMCG sampling campaign, survey questions serve a specific commercial purpose. They qualify UK shoppers, check retailer access, match products to relevant households, and confirm that shoppers understand the requirement to try the product and leave an honest review based on genuine experience.

Practitioners in the sampling space consistently point to one insight: samples work best as risk reducers. In a Costco discussion on Reddit, shoppers said samples were most persuasive when they were already considering the product, wanted to avoid buying a large pack untested, or needed a picky household member to try it first. Sampling survey questions should identify these high-consideration moments, not just cast a wide net.

The IAB UK FMCG guide recommends follow-up research after sampling to measure first-time trialists, future purchase propensity, and referrals generated. That means designing the survey backwards from the KPI. If the goal is reviews, ask review-readiness questions. If the goal is repurchase, ask purchase-intent and price questions. If the goal is product improvement, ask diagnostic questions.

Frequently Asked Questions

What are sampling campaign survey questions?

Sampling campaign survey questions are questions used to choose suitable sample recipients, match them to the right product, collect feedback after they try it, and measure whether the campaign achieved its goals. They are used in product sampling campaigns, not statistical survey sampling.

What questions should you ask before sending product samples?

Ask about category usage, retailer access, household fit, allergies or dietary restrictions, brand familiarity, variant preferences, and willingness to complete the campaign tasks. Put disqualifiers first so ineligible respondents exit early.

What questions should you ask after product sampling?

Confirm whether the person used the product and how many times. Then ask about satisfaction, likes, dislikes, comparison with their usual brand, purchase intent at full price, and whether they are ready to leave an honest review.

How many questions should a sampling campaign survey include?

For most FMCG campaigns, a pre-sample survey of roughly 8 to 12 questions and a post-trial survey of 8 to 10 questions will cover targeting, feedback, and review readiness without causing survey fatigue.

Can you ask samplers to leave a positive review?

No. Ask for an honest review based on genuine experience. The CMA says incentivised reviews must be disclosed and must reflect the reviewer’s genuine opinion. Asking for five-star reviews or making payment depend on positive sentiment is a banned practice.

What is a prequalification question in sampling?

A prequalification question is a screening question asked before sending a sample to determine whether someone is eligible and relevant for the campaign. Examples include category purchase frequency, allergen checks, and retailer access.

Should sampling surveys use open-ended questions?

Yes, but sparingly. One or two open-ended questions in a post-trial survey can surface issues that closed questions miss. Good options include “What would stop you buying this again?” and “What would you tell a friend about this product?”

How do you avoid biased responses in sampling surveys?

Use neutral wording, balanced answer scales, and one-concept-per-question design. Do not describe the product positively within the question itself. Separate behaviour questions (what they did) from opinion questions (what they think), and ask behaviour first.
