Do Survey Incentives Actually Work?
Yes — but with important caveats. Research consistently shows that incentives increase survey response rates, particularly for cold audiences (people who don't have an existing relationship with your brand). The effect is strongest for longer surveys and weakest for very short polls where the effort required is minimal.
The risk is that incentives can attract "professional survey takers" who rush through surveys to claim rewards without giving thoughtful answers. This is especially common with cash incentives and gift cards. The solution is to use incentives strategically — matching the type and value of the incentive to the audience and the survey length.
For many surveys, non-monetary incentives — sharing results, expressing genuine appreciation, or using gamification — are just as effective as cash rewards and don't introduce the same quality risks.
Impact of Incentives on Response Rates
Average response rate lift by incentive type
Relative lift vs no incentive. Actual results vary by audience, survey length, and relationship with respondents.
6 Types of Survey Incentives
Cash or gift cards (guaranteed)
Every respondent receives a fixed reward — a small cash payment, Amazon gift card, or prepaid card. Highest response rates but also highest cost and greatest risk of low-quality responses.
Best for
Long surveys (15+ minutes), B2B research, hard-to-reach audiences
Watch out for
Can attract professional survey takers. Include attention checks to filter low-quality responses.
Prize draw / lottery
Respondents are entered into a draw to win a larger prize. Lower cost per survey than guaranteed rewards, but lower response rate lift. Works best when the prize is highly relevant to the audience.
Best for
Consumer surveys, community research, social media polls
Watch out for
Lottery incentives attract more responses but lower average quality than guaranteed rewards.
Discount or coupon code
Respondents receive a discount on your product or service. Highly relevant to existing customers and prospects. Drives both survey completion and future purchases.
Best for
Customer feedback surveys, post-purchase surveys, e-commerce
Watch out for
Only works if respondents are interested in your product. Ineffective for cold audiences.
Exclusive content or early access
Respondents receive access to a report, whitepaper, webinar recording, or beta feature in exchange for completing the survey. High perceived value at low cost.
Best for
B2B surveys, research reports, product beta programs
Watch out for
The content must be genuinely valuable. Weak content as an incentive damages trust.
Sharing results with respondents
Promise to share the survey findings with respondents. People are naturally curious about how their opinions compare to others. This is a free incentive that also builds transparency and trust.
Best for
Industry surveys, opinion polls, community research
Watch out for
You must actually share the results. Failing to follow through destroys credibility.
Gamification (points, badges, leaderboards)
Award points, badges, or leaderboard positions for survey completion. Particularly effective for community platforms and repeat survey participants. Untold Opinion has built-in gamification for this purpose.
Best for
Community platforms, repeat surveys, engaged user bases
Watch out for
Gamification works best when the points or badges have real meaning within a community.

5 Best Practices for Survey Incentives
Match incentive value to survey length
A 2-minute poll doesn't need a £50 gift card. A 20-minute research survey does. Over-incentivising short surveys attracts low-quality responses; under-incentivising long surveys kills completion rates.
Be transparent about the incentive upfront
Mention the incentive in the survey invitation, not at the end. Respondents who know about the reward before starting are more likely to complete the survey.
Use attention checks to filter low-quality responses
Include 1–2 questions that test whether respondents are paying attention (e.g., "Please select 'Agree' for this question"). Remove responses that fail these checks.
Deliver incentives promptly
Delayed rewards damage trust and reduce participation in future surveys. Automate delivery where possible — instant digital rewards (codes, links) are better than manual fulfilment.
Consider non-monetary alternatives first
For existing customers and engaged communities, sharing results, expressing genuine appreciation, and gamification often work as well as cash — at zero cost.

Free Alternatives to Monetary Incentives
Not every survey needs a financial incentive. For many audiences, these free approaches are just as effective — and don't introduce the quality risks that come with cash rewards:
Share the results
Promise to share findings with respondents. Curiosity about how others answered is a powerful motivator — especially for opinion polls and industry research.
Explain the impact
"Your feedback will directly influence our product roadmap." Knowing their input matters increases intrinsic motivation to respond thoughtfully.
Keep it short
The single most effective way to increase completion rates is to reduce the time required. A 2-minute survey needs no incentive. A 20-minute survey needs a good one.
Personalise the invitation
A personalised email ("Hi [Name], we'd love your thoughts on...") outperforms a generic blast. Personalisation signals that the respondent's specific opinion is valued.
Gamification
Points, badges, and leaderboards create intrinsic motivation without cash. Untold Opinion's built-in gamification system rewards survey participation with points and badges.
Social proof
"Join 500 others who've already shared their opinion." Showing that others have participated reduces the perceived effort and increases social motivation to respond.
