Which errors an SEO audit finds and how to fix them
A few examples from the catalog. The report explains every issue it finds this way.
Redirect chain
/old → /old/ → /new/Several hops in a row slow down loading and complicate crawling.
Set up a direct redirect to the final address.
Noindex page in the sitemap
/sale/ · noindexThe sitemap asks to index the page while the meta tag forbids it.
Remove the page from the sitemap or drop noindex.
Canonical points to an error
canonical → 404You name a main address for search engines that does not open.
Point canonical to a working URL with a 200 code.
Duplicate titles
title × 11Pages with the same title are harder to tell apart in search results.
Give each page a unique title.
Mixed content
https → http://…/logo.pngAn HTTPS page loads files over HTTP, and the browser may block them.
Move all resources to HTTPS.
Does your site have these errors?
Can ChatGPT and other AI services see your site?
A site can look great to Google and still be closed to AI crawlers. The audit shows this with a separate score.

We check technical readiness: robots.txt rules, text in the source HTML and markup. This does not guarantee a place in AI answers.

Why is a technical site audit needed?
Technical errors are the least visible cause of lost traffic: the content can be excellent while some pages are missing from the index because of a blocking directive, return a server error, or lead through a broken link. As long as these problems are not directly visible, they go unnoticed for months, with only a drop in metrics and no clear reason. A regular audit turns scattered symptoms into a concrete list: which addresses do not respond, where a redirect is broken, which pages fell out of the index. Each finding can then be dug into with a dedicated tool: indexing with the page indexation checker, redirects with the redirect checker, and the crawl rules themselves with the Robots.txt and sitemap validator.
How often should the audit be repeated?
After the first full run and fixing the problems found, it is enough to repeat the check once every month or two, or after significant changes to the site: a domain switch, a migration to a new platform, a major restructuring of sections. A daily audit is overkill for most sites – technical problems do not crop up that often.
How is an audit different from checking a single page?
An audit crawls the whole site and looks for systemic problems – repeated errors on pages of the same type, for example. A one-off check answers a question about one specific address and runs faster.
Can someone else's site be checked without permission?
Nothing technically blocks the check, but the audit crawls several pages of a domain, so it should only be run on sites you own or have explicit permission to check.
Does the audit guarantee a rise in rankings after the findings are fixed?
No. A technical audit removes barriers that stop a search engine from processing a site correctly, but it does not replace work on content and on how relevant pages are to the queries they target.
Why does the audit take longer than a speed or SSL check?
It works through several sections of the site in sequence and checks each one from several angles, while a dedicated tool queries a single address on a single parameter.
