Catch SEO regressions after your site changes.
Tracks changes to a page's SEO by saving baselines, comparing later snapshots, and reporting regressions and change history.
When to use it
Use for SEO regression checks, before-and-after comparisons, ongoing change monitoring, or deployment checks.
Give it a page URL and a baseline, compare, or history request; it returns a snapshot summary, SEO comparison, or change history.
What you provide
An API key enables Core Web Vitals fetching; if it is unavailable, CWV fields are null and CWV comparison rules are skipped. The key's source is not specified.
