SEO Experiment Planner — illustrative example

INPUT
Plan an SEO test of clearer titles on comparable tool pages. No baseline data, page count or evaluation window supplied.

RESULT
Hypothesis: clearer titles may improve relevant search click-through.
Groups: select comparable pages; retain an unchanged comparison group where feasible.
Before editing: record page/query impressions, clicks, position, current titles and dates.
Change: title wording only; log concurrent changes.
Evaluation: agree the window and minimum data before starting, then compare like-for-like queries and groups.
Limits: search changes and audience shifts can confound results; no traffic improvement is assumed.

REVIEW
Define the change, comparison group and observation window before editing. Search performance can change for reasons unrelated to the experiment.
