ConvertAtlas SEO brings everything you need for solid on-site SEO into one fast, modular plugin — without the upsells, telemetry or bloat of the big suites. It gives you a live SEO analysis that updates as you type (with a 0–100 score), a modern Gutenberg sidebar panel, clean meta tags, Open Graph and Twitter Cards, a valid JSON-LD @graph, a real XML sitemap at /sitemap.xml, accessible breadcrumbs, a redirect manager with a 404 monitor that suggests fixes, a bulk editor for titles and descriptions, FAQ and How-To schema blocks, and one-click import from Yoast SEO and Rank Math. Every feature toggles from a clean admin dashboard.

Is this a real alternative to Yoast or Rank Math?
It covers the on-site SEO essentials those suites are known for — meta, schema, sitemaps, breadcrumbs, redirects and content analysis — in a lighter, fully open-source package. It does not try to replicate their paid AI features or integrations, but for most sites it is a complete, capable SEO solution.
Should I run it alongside another SEO plugin?
No. Run only one SEO plugin that outputs meta tags, schema and sitemaps, or you will get duplicates. Deactivate other SEO suites first. ConvertAtlas SEO automatically disables WordPress core sitemaps to avoid conflicts.
Where is the XML sitemap?
At /sitemap.xml once activated, with per-type sub-sitemaps and a human-readable stylesheet. The sitemap line is also added to robots.txt automatically.
Does the content analysis send my text anywhere?
No. The analysis runs entirely in PHP on your own server when you save a post — there are no external requests, accounts or limits.
Is it really free and open source?
Yes. ConvertAtlas SEO is GPL-2.0 licensed, has no paid tier, no telemetry and no account requirement. You can read and modify every line.
