 I have received competent help directly from the founder Steffen on several occasions. Not only did he help me technically, but he was also able to use his years of experience as an experienced tester to help me with my tests time and time again. What's more, the tool is really inexpensive and no comparison to the more expensive competitors.

Varify.io Success Stories

Frequently asked questions

Why is Varify.io® proportionally so much cheaper than other providers?

At Varify.io®, we want to make digitally optimizing a site possible for all businesses, regardless of their starting point. We focus on affordable and unlimited testing without compromising on the variety of features.

Unlike other providers, we do not pay per user ourselves and rely on existing tracking systems, which allows us to pass on the more favorable conditions to our customers.

This approach is in line with our "single source of truth" principle, which is why we do not keep our own goal tracking, but focus on seamless integration of analytics tools for A/B test evaluation.

How do I integrate Varify.io® on my website?

The Varify.io® snippet should be included at the beginning of the head section of your website. Alternatively, you can simply add the snippet via a tag manager.

Can I try Varify.io® without having the snippet integrated on my website?

You don't have to integrate the snippet into your website just to try out the editor. For this you can use the  Varify.io® Chrome Browser Extension download. Go here to the Explainer video.

How do I set up a new A/B test with Varify.io®?

Create a new variant and save it under a name of your choice.
Now you can define your A/B test setup directly in the Varify.io® dashboard for the created variant and then start it directly. The A/B test setup includes the definition of the targeting and the traffic distribution. 

Does Varify.io® affect the loading speed of my website?

The Varify.io® snippet loads with only 11.5kb and is thus usually completely loaded in under 30ms - virtually imperceptible. So your web pages stay lightning fast.
