What a technical SEO audit covers (and what you should get from one)
A plain-language guide to what a technical SEO audit checks, how to read the findings and what a useful audit report looks like.
Most websites that struggle in search don’t have one big problem. They have a dozen small ones that add up: pages search engines can’t reach, duplicate versions of the same page, slow templates, missing links between related content. A technical SEO audit finds those problems and, more importantly, tells you which ones are worth fixing first.
This guide explains what a proper audit checks, in plain language, and what you should expect to receive at the end.
What “technical SEO” actually means
Technical SEO is the work of making sure search engines can find, render and understand your pages, and that the site is fast and secure enough for people to use. It doesn’t replace good content or a strong reputation. It makes sure the content you already have gets a fair chance.
A useful way to think about it: content and links decide how well a page can rank. Technical SEO decides whether it can compete at all.
What a technical SEO audit checks
1. Crawling: can search engines reach your pages?
The audit starts by crawling the site the way a search engine does, following links from page to page. This shows:
- Pages that return errors (404s) or server errors (5xx).
- Redirects, especially chains where one URL redirects to another, which redirects again.
- Important pages that are blocked in
robots.txtby mistake. - “Orphan” pages that nothing on the site links to, so crawlers rarely find them.
2. Indexing: are the right pages in Google, and only those?
Google Search Console shows which pages are indexed and why others are not. Common findings include:
- Important pages marked
noindex, often left over from a staging site. - Duplicate pages competing with each other:
httpandhttps, with and withoutwww, trailing slashes, filter and tracking parameters. - Canonical tags pointing to the wrong page. A canonical tag tells search engines which version of a page is the main one when similar URLs exist.
- Thin or near-empty pages (tag archives, empty categories) taking up crawl attention.
3. Site structure and internal links
How pages link to each other tells search engines which ones matter most. The audit checks how many clicks it takes to reach key pages, whether service or product pages get links from relevant content, and whether navigation is crawlable (plain links rather than script-only menus).
4. Speed and Core Web Vitals
Core Web Vitals are Google’s measures of loading speed, responsiveness and visual stability. The audit looks at field data (real visitors) where available, then traces slow pages to their causes: oversized images, render-blocking scripts, heavy themes, slow hosting.
5. Mobile usability
Google primarily uses the mobile version of a page. The audit checks that content, links and structured data on mobile match desktop, and that text, buttons and forms are usable on a small screen.
6. Structured data
Structured data (schema markup) describes a page in a format search engines can read directly: an organization, an article, a product, a set of FAQs. The audit checks that it is valid, accurate and actually matches what is on the page.
7. Security and housekeeping
HTTPS everywhere, no mixed content, an accurate XML sitemap containing only indexable pages, and sensible handling of old URLs.
What you should get at the end
A list of 300 warnings from a tool is not an audit. A useful audit gives you:
| Part of the report | Why it matters |
|---|---|
| A short summary in plain language | So decision-makers understand the situation without reading everything. |
| A prioritized issue list | Each issue rated by likely impact and effort, so the biggest wins come first. |
| Clear explanations | What the problem is, where it occurs and why it matters for your business. |
| Specific fixes | Written so a developer can act on them, with example URLs. |
| A way to measure progress | What will be checked after the fixes, and when. |
How often should you run one?
A full audit makes sense before or after major changes (a redesign, a platform move, a big content expansion) and roughly once a year otherwise. In between, regular monitoring in Search Console catches new problems before they cost traffic. If you are planning a redesign, read our website redesign SEO checklist first.
A technical audit is the start, not the finish
Fixing technical problems removes obstacles. It doesn’t create demand on its own. The best results come when technical fixes are paired with content that matches what your customers search for, and with a site structure that leads visitors to the right page. That is how we approach SEO: audit first, then a roadmap that connects the fixes to business goals.
