Technical SEO audit services for website optimisation

Implementation-ready, not a 200-issue dump

The reason most technical audits stall is that they read like a tool export. Ours are built for website optimisation: each finding carries an impact rating, an effort estimate and a plain-English explanation of the fix, grouped by template so a developer can ship a change once and clear it across thousands of URLs. Where it helps, we add log-file analysis to show how bots actually crawl your site and where budget is wasted.

Best for sites where the technical foundations are the bottleneck

These services are the right call after a migration or redesign, when rankings have dropped without an obvious cause, or when a large or JavaScript-heavy site has outgrown the last person who understood its structure. If you are comparing the best firms for technical and on-page SEO audits, the test is simple: ask to see how the findings are prioritised, not how many issues they can list.

Technical SEO audit price: what changes it

Our technical SEO audit services start from £595 for a focused audit. From there, the price moves with a handful of things we can usually pin down before we start: how many URLs and page templates the site has, whether key content depends on JavaScript to render, whether there are multiple languages or markets to check, whether log-file analysis is included, and whether the audit follows a migration or redesign that needs a before-and-after comparison.

Every audit is quoted as a fixed fee once we have scoped the site, so the technical SEO audit price you are quoted is the price you pay. When comparing quotes from different firms, check what each one includes against that list, not how many pages the report runs to. Our SEO audit cost guide explains the wider price bands across technical, content and full audits.

How our technical SEO audit works, step by step

We begin by scoping the site with you: roughly how many URLs and page templates it has, which platform or framework it runs on, whether key content relies on JavaScript, and whether anything has changed recently, such as a migration, a redesign or a new CMS. That shapes where the audit spends its time and fixes the fee before any work starts.

Next, we crawl the site twice, once reading the raw HTML and once rendering the JavaScript as Google does, and compare the two. Content, links or canonical tags that only appear after rendering are a common reason good pages are slow to be indexed, or not indexed at all.

Then we set the crawl against what Google actually reports. With read-only access to Search Console we compare the pages we found with the pages Google has indexed, excluded or never discovered, check that your XML sitemaps list the URLs you want ranked, and review Core Web Vitals from real-user field data rather than a single lab test. Where you can share server logs, we add log-file analysis to show which sections bots spend their time on.

Finally, we group every issue by the template that causes it, rank each fix by impact and effort, and write it up for your developers. A finding is only finished when it says what is wrong, on which URLs, why it matters and what the fix looks like.

What you receive at the end of a technical SEO audit

An executive summary that explains the state of the site in plain English, the prioritised findings with example URLs for each, and a developer appendix organised by template so each fix can be shipped once and cleared across every page built on it. We then walk your team through the findings on a live readout call, so your developers can ask questions before they start rather than after.

Where this sits alongside our methodology page

This page is for buyers choosing a provider. If you want the full technical methodology, exactly what we examine across crawl, rendering, structured data, Core Web Vitals and log files, see our detailed technical SEO audit page. For sites where content and authority are also in play, the broader SEO audit services page combines all three.
