CORPUSFree tool
Check one page's SEO tags and files.
Paste a page address. Corpus Plan checks its title, meta description, Open Graph tags, canonical, noindex, the site's robots.txt and sitemap, and its JSON-LD.
Free, no account. 3 free tool runs per connection per day, shared across the tools.
Same rules as the audit
Each row uses the check the full audit runs, with the same length limits and the same fix.
Organization schema
Built only from what the page prints: its own JSON-LD, og:site_name, a logo image, profile links, and tel: or mailto: links. Anything missing is named, never filled with a placeholder.
One page, not the site
The full audit crawls up to 20 pages and scores five pillars. This checks the one page you enter.
