SEO split test planner

One credit, and a Search Console export for the pages you want to test. All the statistics run in code rather than through an API, so the cost is the base rate. Free gives you one full plan at a time; Pro saves them so you can come back when the test finishes. See pricing. A plan costs one credit whether it covers ten pages or a thousand, since the work is the same. The results analyzer is priced the same way.

It is processed to build the plan and then discarded. Without an account nothing about the run is stored once the result comes back — not the file, not the URLs, not the output. With a Pro account the plan is saved to your history so you can return to it, and you can delete any run or the whole history. The privacy policy has the detail. Anonymous runs are not logged anywhere, including in error traces.

Because without one you are measuring seasonality and calling it a result. Traffic moves for a dozen reasons that have nothing to do with your change. A matched control group experiences the same seasonality, so the difference between the two groups is the part your change is responsible for. That comparison is what the results analyzer reads. Picking the control group by hand is where most homemade tests go wrong, usually by choosing pages that were already trending differently.

Then it says so rather than giving you a number that will mislead you. Below a certain volume no test length will detect a realistic effect, and a plan that pretends otherwise wastes eight weeks. It will tell you the smallest effect your data could detect, so you can decide whether that is worth running at all. Being told a test is not worth running is the cheapest result the tool can give you. The AI SEO tools guide makes the same argument about measurement generally.
