Indexing & technical setup: what exactly is checked
Retrieval · redirects · robots.txt · sitemap. Every subtopic leads to its checkpoints with weight and explanation; the list comes from the audit engine itself.
Accessibility and status
Status 200 for pages, 404 for missing, no soft-404, no dead internal links.
4 articles
Forwarding and addresses
Forwarding chains, canonical addresses, meta-refresh, old addresses after relaunch.
5 articles
robots.txt and Sitemap
What the sitemap calls must not block the robots.txt; Indexability and traps.
5 articles
Content in HTML
The content is in the first HTML, without load lock, without cloaking, without scroll hiding.
5 articles
Language and scheme
Languages match, hreflang refers back, JSON-LD is valid.

What is measured
This audit area rates from findings and measured values, not from a countable set of rules. That is why this page lists which signals are collected.
Accessibility
Replies the address, and with which status code — checked along all forwardings.
robots.txt
Whether the file exists, is readable and whether it locks out the checked pages.
Sitemap
Whether a sitemap is specified and retrievable and whether it fits the actual page structure.
Transfer chains
How many jumps lie between the entered and the final address.
Indexation instructions
noindex data in meta tags and HTTP headers — the most common cause that a finished page cannot be found.
Good to know
- One side can be perfect and still locked out – that stands out here.
- Forwarding chains and status codes are fully logged.
