Automate it with SEOitis

Want schema on every article - automatically?

SEOitis generates FAQ schema, BlogPosting schema, BreadcrumbList, and Organization markup on every article it ships. Run a free site analysis to see the schema we'd add for your site.

Why we built these

The tools were the prototype. SEOitis is the production version.

Every SEOitis-published article goes through schema generation, meta tag optimization, SERP validation, robots.txt maintenance, and Core Web Vitals review. We built the tooling for those steps internally.

The free tools here are the same engineering, exposed as standalone utilities. If you like what they do one page at a time, SEOitis does the same thing across hundreds of pages automatically.
