From SEO audit to priority list, step by step

What does an SEO audit cover?

An SEO audit is a structured check of your website for everything that costs visibility in search. The benchmark is Google Search Essentials, which consist of three parts: the technical requirements, the spam policies and the key best practices.

The minimum technical requirements are short. Googlebot must not be blocked, the page must respond with status 200 and it needs indexable content. On large websites, entire page types often fail on exactly these points, for example because of a noindex in the template or an overly broad rule in robots.txt.

Audit and monitoring

An audit answers the question of where the website stands today. Monitoring checks the same points continuously and alerts you when something changes. The two complement each other. The audit defines what good looks like, and monitoring keeps it that way.

Preparation

A good audit starts before the first crawl. Without a goal and a data basis, you end up with a long list that nobody works through.

1. Set the goal. Is it about a traffic loss, a planned relaunch or a status review?
2. Define page types, such as category, product, filter, guide and brand, with example URLs for each type.
3. Connect data sources. Search Console provides clicks per URL, analytics provides revenue or leads. Log files show what Googlebot actually fetches.
4. Configure the crawl. Turn on JavaScript rendering and add URLs from the XML sitemap and Search Console as extra sources, so that unlinked pages show up too.
5. Clarify access. Many servers block unknown crawlers. An IP allowlisting is often needed.

The audit areas

The following table is the checklist for the technical part. Most points have their own guide with details.

You can check individual responses quickly in the terminal. This shows the status code, redirect and a noindex in the header at a glance.

The example shows a typical finding. The page responds with 200, but the header excludes it from the index.

What you can leave out

Google's SEO Starter Guide lists points that play no role in search. These include the meta keywords tag, a particular text length, keywords in the domain name and the order of headings. According to Google, duplicate content is not a violation of the spam policies. It does cost crawl resources, though. In an audit, such points belong in a footnote at most.

Prioritizing

The first crawl of a large website is often overwhelming. Tens of thousands of missing meta descriptions sit next to a noindex on every category. So sort every finding by three questions.

1. How many URLs does it affect, and which page types?
2. How many Search Console clicks do these URLs have, or how much revenue?
3. Does the error prevent crawling or indexing, or does it only make the presentation worse?

The result is a short list with owners. Each point describes the cause, the affected page types, example URLs and the expected effect.

After the audit

Once fixes are in place, you crawl the affected page types again and check whether the fix is live. In Search Console, URL Inspection shows how Google now sees a page. According to Google, it takes hours to months before changes show up in search.

The risk after an audit is the next release. A template update can bring back a noindex or overwrite canonicals, and the last audit will not notice. That is why it pays to repeat the most important checks regularly.

Common mistakes

• Crawling without JavaScript rendering. Shops and single-page apps then lack links and content.
• Weighting all findings equally and starting with the easiest.
• Only checking linked URLs. Pages that only appear in the sitemap or Search Console stay invisible.
• Handing over the audit as a PDF and never opening it again.
• Checking points that Google says play no role, such as meta keywords.
