A safety linter that refuses to nuke your site
Most SEO damage is self-inflicted: bulk content and query-string duplicates that trigger a penalty. Our safety linter runs on every change — ours and yours — and blocks those patterns before they can ship.
Blocks, not flags
A normal SEO tool flags problems and leaves you to ignore them. Our linter is a gate: if a change would create near-duplicate content, query-string sitemap bloat, a broken canonical or hreflang, or a thin bulk page, it is blocked — it cannot publish. The rule that would be violated is the reason it stops.
Built from a real demotion, encoded as code
We built this after watching a query-string duplication issue erase most of a site’s organic traffic overnight. Every rule in the linter maps to a real failure mode from that playbook — so the mistakes that demote sites simply can’t be made through us.
It protects you from your own automation, too
The same linter gates the content we generate for you and any bulk change on your site. It also enforces safe removals — we won’t 404 or prune a page that still earns clicks or impressions, and we retire pages with 410s, not 404s.
Available as an API
The linter is also available on the API / white-label tier, so you can run the same guardrail inside your own product or workflow before anything you build touches a live site.
