How to set custom test periods for SEO tests

Question: Can you have custom control and test periods for SEO tests?

Answer: Yes. On the first test setup screen, we have the default periods of 2 - 8 weeks, on the screen where we ask you to confirm the control and test period dates. So for example, this means you can have a 4 week control period, and an 8 week test period.

To have any other time periods, use the date-picker instead on the pre-set 'Test Periods', by clicking ont he calendar icons and selecting the dates you wish. Then click 'Next':

If a test is still running and the results aren't conclusive, you can edit the test and extend the end date of it.

If the test has finished running - you can't edit the end date. The best thing to do is Copy the test, and extend the dates on that new instance of the test.
