At Zeydoo, we try to test each offer, so we can give you professional support for everything related to starting and running your campaign, from targeting to choosing the best ad creatives. What we prepared for you today is a small case study on the most popular offer of October and November 2020. 

The Offer

Fin Survey #1203 is an offer with a simple flow. The conversion is counted when a user completes a survey (a user doesn’t even need to enter their email) after that, he’s redirected to the “thank you” page. Such offers always have small payouts, usually less than one dollar, but it is compensated by their high CR. 

To start, we ran a test offer on pop-ups for several countries – India and South Africa. Because we didn’t want to expand the testing budget, we chose mainly Tier-3 countries.

The traffic went through a direct link straight to the landing page, without a pre-lander. Later we added push notifications with a higher bid for South Africa. Finally, the campaign targeting India did not pay off, so we decided to stop it.

Then we thought, it will be beneficial to expand our list of countries, so we added Kenya and Nigeria. Kenya worked out the best way, out of all countries, so let’s talk about this campaign.


First, we ran the offer without a pre-lander, trying to compensate with high bids, but this strategy did not work out, so we had to test different pre-landers.

We got to test all four of them, all different – with a focus on the unique opportunity to earn money. It’s great to use a country flag and add a call to action, prompting to complete the survey (there is an example below). 

We also tried another approach – a success story with a photo of a prosperous Kenyan, but the simplest creative, with a flag and mentioning an opportunity to earn money, worked best.

Testing & Optimization

At first, we launched one campaign, then optimized the zones + IP + states/cities + OS version.

If it was showing some potential at least after a day, we were replicating the campaign with the settings already optimized, to make several instances (usually 2-5), to run them in parallel.

All users that were not unique were grouped by the tracker and sent via rotation to a direct link to the survey, using simple pre-landers like this one:

Also, we tried out the light theme:

The testing process

All tests were conducted via CPA Goal with the $0.01 bid. If in certain GEOs we could set higher bids (for example, the payout for Kenya was $0.1 at the start), CPA was set as half of the payout (~$0.05). 


The results were really promising. For such offers with a simple flow, the most important thing is to find the right GEO and get maximum conversions.

Your creatives and a good pre-lander have the biggest impact on your CR.

Do not forget, that it is the pre-lander that warms up the audiences and motivates users to reach the end of the funnel, whether it is a survey or a purchase. You should always test several ad creatives, because you never know, which one will give the best effect! 

Good luck with all your offers!
