Optimisation and testing
Reading results without fooling yourself
Small samples, algorithm updates and seasonality produce convincing illusions. Demand a control group before you believe a result.
Why this lesson matters
This lesson belongs to Optimisation and testing, the part of Analytics & Optimisation where the goal is: improve what the data exposes.
Read it once, then do it straight away on a real site inside RankTracker. Nothing here is theory for its own sake — every step produces something you can show a client.
Do it now
- 1Open RankTracker with sample data already loaded, so you are not stuck on setup.
- 2Track the keywords from this lesson.
- 3Run a title test on ten pages with a ten-page control group and document the CTR delta.
