Is this split testing or before-and-after testing?

Before and after on the same page. A true SEO split test divides hundreds of similar pages into control and variant groups, which most client sites do not have. RankNest measures one page against its own Search Console baseline, which works on a site with 20 pages as well as 20,000.

How long should an SEO test run?

The default is 28 days, matching the baseline window, so both sides cover the same number of weekdays and weekends. Shorter tests are allowed, and the results window is never longer than the test itself.

Search Console data is a few days late. Does that skew the result?

No. Windows end on the last day Google has data for, not on today, and a finished test syncs once more three days after it ends so the late days are counted.

Why did a test with a higher CTR not count as a win?

CTR only decides a result when the page had at least 20 clicks across the two windows. On a handful of clicks, one extra visit can move CTR by 30 percent in either direction, so below that the verdict comes from position and clicks instead.

Can I run more than one test on a page?

Yes, one after another. RankNest groups every test under its page so you can see the history. Two tests running on the same page at the same time make it impossible to say which change did the work, so finish one before starting the next.

How RankNest decides whether a test won

An SEO test is only as good as its measurement. These are the rules every RankNest experiment follows, so a result you show a client holds up when they ask how you got it.

The baseline is the whole page: When a test starts, RankNest records the page's clicks, impressions, CTR and average position from Search Console for the previous 28 days. It uses every query the page earns, not one keyword you picked.
Both windows are the same length: The results window matches the baseline and never starts before the test did. Windows end on the last day Google has data for, so reporting lag does not make every test look worse.
CTR needs enough clicks to count: A test wins when position or clicks improve and neither gets worse. CTR only decides the result once the page has at least 20 clicks across both windows, because on smaller numbers it swings in both directions.
You record the decision: Finished tests wait in a Review tab until you mark them keep, roll back, inconclusive or re-test. Your verdict is kept for the record and never changes the win rate, which stays purely on the numbers.
