Course 09: Validate changes

SEO Testing

Many SEO changes are shipped on best practice alone. Testing shows whether a change actually improved performance, and catches mistakes before they spread across a whole site.

SEO tests compare groups of pages rather than groups of users, and technical tests validate redirects and indexing before and after launch.

In this course, you’ll learn how to plan experiments, validate technical changes, and monitor outcomes after updates go live.

Context

Why SEO Testing matters

Search performance is affected by algorithm updates, seasonality, and competitors, so before and after comparisons alone can mislead.

Testing separates real effects from noise, limits the risk of harmful changes, and builds a record of what works on your site.

In SiteAuditLint

Validate changes with crawls

SiteAuditLint crawls confirm that changes are live: redirects resolve in one hop, pages are indexable, and titles are unique.

Compare crawls before and after a release to see exactly what changed.

Summary

Key takeaway

SEO testing replaces assumptions with evidence: change one thing, compare against a control, validate technically, and document the outcome.

The lessons examine each step in more detail, starting with seo experiments.
