TL;DR: A deep review of your website’s technology and structure to find issues preventing it from ranking.
In a nutshell
A technical audit checks the plumbing of your site: crawlability, indexability, page speed, mobile usability, structured data, and security. It’s separate from content or backlink work. Example: an audit might find that a single misconfigured robots.txt rule is blocking Google from indexing your entire blog section.
Quick answer: A technical SEO audit reviews the underlying technology of a website, separate from its content or backlinks, to identify issues that prevent pages from being crawled, indexed, or ranked properly. It covers crawlability, indexability, site architecture, internal linking, page speed, mobile usability, structured data, and security.
What Is a Technical Audit?
A technical audit is an in-depth review of your website’s technical aspects that affect its performance, crawlability, and indexability. It focuses on identifying technical issues that could hinder your site’s ability to rank well in search engines or negatively impact user experience. A technical audit assesses elements such as site speed, mobile responsiveness, URL structure, broken links, and the website’s overall structure to ensure that it is optimised for search engine crawlers and users.
At BrisTechTonic, we conduct comprehensive technical audits that identify potential issues affecting your website’s SEO performance. By addressing these issues, we can ensure that your site functions at its best and improves its rankings in search engine results.
Why Technical Audits Matter
Technical audits are essential for ensuring that your website is optimised for search engines and provides a smooth user experience. Here’s why technical audits matter:
- Improves Site Crawling and Indexing: Technical issues like broken links or poor URL structure can prevent search engines from crawling and indexing your website correctly. A technical audit ensures that search engines can fully access and index your content, improving your visibility in search results.
- Enhances Site Speed: Site speed is a critical ranking factor in SEO. A slow website can lead to poor user experience and lower search rankings. Technical audits identify and fix issues that slow down your site. Core Web Vitals are the primary measure here.
- Improves Mobile Usability: With mobile-first indexing becoming the norm, ensuring your website is mobile-friendly is essential. A technical audit checks your site’s mobile usability, ensuring it performs well across all devices.
- Prevents SEO Issues: A thorough technical audit helps prevent issues that could lead to ranking penalties, such as duplicate content, incorrect redirects, or missing meta tags.
How to Conduct a Technical Audit
Conducting a technical audit involves analysing various aspects of your website’s performance. Here’s how we help our clients with a technical audit:
1. Check Site Speed and Performance
We test your website’s speed and identify any issues that could be causing slow page load times. Slow websites lead to higher bounce rates and lower search rankings. We recommend fixes such as optimising images, leveraging browser caching, and minimising HTTP requests.
2. Evaluate Mobile Usability
Mobile usability is crucial for SEO, as Google uses mobile-first indexing. We test your website’s mobile responsiveness, ensuring that it displays properly on different devices and screen sizes. We also check for mobile-friendly elements such as touch-friendly navigation and legible fonts.
3. Identify Crawl Errors
We use tools like Google Search Console and Screaming Frog to identify crawl errors on your site. These errors can prevent search engines from indexing your pages. We identify 404 errors, redirect loops, and other issues that may be hindering search engine crawlers.
4. Review URL Structure and Internal Linking
A well-structured URL hierarchy helps search engines understand your site’s content and improves user experience. We ensure that your URLs are clean, descriptive, and optimised for SEO. We also assess your internal linking structure to ensure that all pages are accessible to search engine crawlers and users.
5. Check for Duplicate Content
Duplicate content can harm your SEO by causing confusion for search engines about which page to rank. We identify and resolve issues related to duplicate content, including duplicate meta tags, titles, and body content.
6. Ensure Proper Use of Redirects
Redirects are necessary when URLs change or when pages are deleted. However, improper use of redirects (such as redirect loops or broken redirects) can harm your SEO. We ensure that your redirects are set up correctly and that old URLs are redirected to the appropriate new pages.
7. Check for Structured Data
Schema markup helps search engines better understand the content of your website. We review your site’s structured data to ensure it’s implemented correctly and optimised for rich snippets in search results.

Common Technical Audit Mistakes
- Neglecting Mobile Usability: Failing to optimise your website for mobile devices can negatively affect your rankings and user experience. We ensure that your site is fully responsive and mobile-friendly.
- Ignoring Crawl Errors: Crawl errors can prevent search engines from indexing important pages on your site. We ensure that all pages are accessible to search engines and that any crawl errors are fixed.

Frequently Asked Questions
What is included in a technical SEO audit?
Eight areas: crawlability (robots.txt, internal linking depth), indexability (canonicals, noindex, sitemap), site architecture (URL structure, hierarchy), page speed (Core Web Vitals), mobile usability, HTTPS and security, structured data (schema), and rendering (JavaScript and CSS execution). Comprehensive audits also check log files for crawl behaviour.
How is a technical audit different from a regular SEO audit?
A regular SEO audit covers all SEO levers: technical, content, backlinks, and competitive. A technical audit is just the technology layer. For most established sites, a technical audit is a subset of broader SEO work; for new or migrating sites, it’s usually the first piece of work that needs doing.
How often should I do a technical audit?
Annually for stable sites. After every major change (migration, redesign, platform switch, theme update). When organic traffic drops without an obvious content or competitive cause. When Core Web Vitals or mobile usability metrics start failing in Search Console.
Can I do a technical audit myself?
Some of it, yes. Tools like Screaming Frog, Sitebulb, and Ahrefs Site Audit automate most of the data collection. The harder part is interpreting the results: which issues actually matter for your site, in what order to fix them, and how each fix should be implemented in your specific stack. That’s the value-add of a professional audit.
