Automated SEO audit: what does it actually check?

The checks you should find in the report

When you manage your site alone, you do not need to memorize every technical term. Above all, you need to understand what each check lets you conclude. Here are the checks to look for in an audit, depending on the tool’s access and capabilities.

1. Page responses. Does a URL open correctly? Does it redirect elsewhere? A server error does not call for the same action as an old page intentionally removed.
2. Crawler directives. Does robots.txt contain a restriction? Does a page have a noindex directive? These mechanisms serve different purposes: a noindex directive must be readable to be taken into account. Google’s explanation of noindex.
3. The sitemap. Does the file exist and contain the URLs you want discovered? Its presence alone does not prove those pages are indexed.
4. The declared canonical URL. Does the page specify a consistent primary URL? Before fixing it, check whether the variants are intentional.
5. Titles and main content. Does the page have a descriptive title and an identifiable topic? A tool can collect tags; the text still needs reviewing to judge its relevance.
6. Structured data. Is the markup readable and consistent with what visitors see? The presence of markup does not prove a Google rich result.
7. Rendered content. Does the important text appear in the version actually displayed? This is useful when part of the page depends on JavaScript.

On the French RosoAI site, for example, a check on September 9, 2026 found that the old URL /politique-privacy returned a 404 even though the privacy page still existed at another address. The problem came from the URL change. The fix is to redirect the old URL to the right page, then check the destination and absence of a loop. This check alone does not tell you whether Google has already processed the change.

Accessible, indexable and indexed: three different states

A page can open in your browser without being in Google’s index. Conversely, information shown in Search Console may reflect an older crawl rather than the version you just fixed.

URL inspection separates information about the indexed version from the live test. The live test checks access to the current page but does not guarantee future indexing. See how URL inspection works.

Look for the source and date of the finding in your report. ‘I can open this page’ and ‘Google has indexed this page’ should not be presented as the same conclusion.

A performance score needs context

A lab test simulates loading conditions. Field data describes real visitors’ experiences when available. Both can help explain a problem, but they do not answer exactly the same question.

Core Web Vitals cover the display of main content through LCP, responsiveness through INP and visual stability through CLS. Real-world data remains central to these indicators; a lab measurement does not replace them all. Understand Web Vitals.

If your audit flags slowness, look at the affected page, device, measurement conditions and what actually slows down the visit. The number alone does not tell you which fix matters most for your business.

Turn alerts into simple decisions

Here is a fictional example: your booking page returns a server error, three articles have similar titles, and a secondary image is heavy. I would start by restoring booking, because the outage prevents an action directly related to your business.

For each issue, keep a short record with these four details:

• The fact: what was measured, its URL and date.
• The possible impact: what it may prevent, without presenting it as certain.
• The proposed action: a specific change, with a backup when needed.
• The check: the test to rerun to know whether the fix works.

A title similar to another page’s may deserve a review. By itself, it is not proof of a penalty. Avoid changing dozens of pages at once without understanding what triggered the alert.

What automation cannot decide on its own

A tool may not know your margins, seasonality, customer conversations or products you want to stop selling. Yet those details change your priorities.

A drop in clicks can also coincide with several events. Finding a technical change does not prove it caused the drop. Examine the period, pages and queries involved.

The same caution applies to AI visibility. A technical audit does not certify that your brand will appear in an assistant’s answers. If these concepts are still getting mixed up, read the difference between SEO and GEO.

A one-off audit or ongoing monitoring?

An on-demand audit gives you a baseline before working on your site. Monitoring compares observations over time and spots changes.

At RosoAI, the SEO/GEO Kit fits the first use case: you start the work when you need it. Hermes runs on your server to perform scheduled checks and keep a record over time. The choice depends on what you need, not how many alerts you want.
