Catch differences you cannot see on screen

Find what holds your SEO back
Missing tags, accidental noindex directives, incorrect canonicals: find technical issues and the pages that need attention.
Get alerts you can act on
See affected pages, severity and before-and-after changes in your report. Email alerts flag detected regressions.

Frequently asked questions
Is Seogard free?
The self-hosted version is free, under the BSL 1.1 license (source available), with no page limit. You install it on your own server with Docker. The Cloud version is usage-based, for teams that prefer not to run the infrastructure.
Why compare HTML with JavaScript rendering?
To catch issues a visual check can miss: a changed title, missing links or content absent from the initial HTML. Seogard shows the differences so you can fix how your pages render.
How do alerts work?
Schedule crawls or trigger them on demand and from your CI/CD pipeline. Enable notifications to receive detected regressions and resolved issues by email, with affected pages and severity.
