What does the crawler check per page?

Onpage hygiene in one pass — what search engines and AI answer engines see.

HTTP status & redirects

200, 301, 302, 404, 5xx — captured per URL. Redirect chains are followed up to 3 hops. 404 and 5xx URLs are prominently flagged in the result.

Title & meta description

Present? Length? Duplicates? We show title and meta for every page and flag empty or duplicate tags.

H1 structure

Exactly one H1 per page is standard. We flag pages without H1, with multiple H1s or with an empty H1.

Schema.org markup

Which Schema.org types are embedded? Article, FAQPage, Product, Person, Organization, BreadcrumbList? Schema markup is mandatory for AI visibility (GEO).

Internal linking

Per page: incoming and outgoing internal links. Orphans (pages with no incoming links) and dead ends (pages with no outgoing links) are flagged.

Word count & thin content

How many words per page? Thin content (< 300 words) is a classic quick win. With the Rankmio account: crawl depth vs. the homepage, orphan detection and multi-page reports.
