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.

Pages with a 4xx code

/promo/2023 → 404

Robots and visitors reach a page that does not exist, and crawl time is wasted.

Replace the links with working ones or set up a 301 redirect.

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/ · noindex

The 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 → 404

You name a main address for search engines that does not open.

Point canonical to a working URL with a 200 code.

Duplicate titles

title × 11

Pages with the same title are harder to tell apart in search results.

Give each page a unique title.

Mixed content

https → http://…/logo.png

An 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.

  • ChatGPT
  • Claude
  • Perplexity
  • Google / Gemini
  • Bing / Copilot
  • Apple / Siri

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

Why do you need an SEO site audit?

Technical errors quietly cost traffic: a page can have great content and still stay out of the index because of noindex, return a server error or hide behind a redirect chain. Such problems stay invisible for months while the numbers drop. An audit turns scattered symptoms into a concrete list: which addresses do not respond, where a redirect is broken, which pages are closed to search and how to fix it.

How many pages can I check for free?

Up to 20 pages without signing up and up to 50 with a free account. On a paid plan, one audit covers up to 500 pages. You choose how many pages to check this time with the slider under the address field.

How long does a check take?

A small site is usually checked in a few minutes. One audit is limited to 10 minutes without signing up, 30 minutes with a free account and an hour on a paid plan. You can close the tab: the check continues in the background and the report is saved.

Will the audit harm my site?

No. We send no more than 2 requests per second and follow robots.txt by default, so a typical site will not notice the load. If you need to check closed sections of your own site, robots.txt can be ignored with the switch under the address field.

Where should I start fixing?

Start with the “What to fix” block: it collects the three issues that affect the score the most. Then go by severity: errors first, then warnings and notices. Each issue card has an explanation, instructions and a list of addresses, and you can ask the AI assistant about anything unclear. The report exports to PDF and CSV, and a public link can be shared with your developer.

How often should I repeat the audit?

After the first run and the fixes, checking once every one or two months is enough, plus after noticeable changes: a release, a move to a new CMS or domain, or a restructuring of sections. A repeat audit is compared with the previous one and shows which issues are gone and which are new.

How is an audit different from checking one page?

An audit crawls many pages and finds problems between them: duplicate titles and content, pages without incoming links, sitemap and mirror errors. For a question about one specific address, focused tools are faster: HTTP status checker, page indexation checker or robots.txt and sitemap validator.

Can I check someone else’s site?

Technically nothing blocks the check, but the audit crawls several pages of the domain. Run it on your own sites or on those you have permission to check, such as a client’s site.

Will rankings grow after the fixes?

This cannot be guaranteed: rankings also depend on page content, links and competitors. The audit removes technical obstacles that stop search engines from crawling, indexing and showing the site properly. It is the necessary foundation, not a replacement for work on content.
