Experimentation
Visual multi-variant tests
Change what a page says, how it looks and where things sit, without a deploy and without a developer for most of it.
A multi-variant test serves two or more versions of a page and measures which one performs better against the objective you picked. In Pertento you build those versions by pointing at elements on your own live site. The editor opens from a Chrome extension, so there is no staging copy to keep in sync and nothing to rebuild between changes.
Edits cover text, styling, layout and position. Anything the editor cannot express you can write as custom CSS or JavaScript against the variant, which means a test is never blocked on the tool. The change is saved against the variant rather than the page, so the original is untouched and rolling back is a matter of stopping the experiment.
Assignment is sticky: a visitor who has seen variant B keeps seeing variant B across sessions, so the experience stays coherent and the measurement stays clean. Rendering is anti-flicker with multiple independent fail-safes, so nobody watches the original page flash into the test.
A new experiment is a draft. It only reaches visitors once you start it and the website is published, so nothing goes live by accident while you are still building it.
