No website can stand without a strong backbone. And that backbone is technical SEO. It ensures search engines can crawl, index, and rank your site while delivering a smooth user experience. Without it, even great content may struggle to rank.

This technical SEO audit checklist covers seven key factors that impact performance. From crawlability to structured data, these checks keep your site optimised. Use this checklist to fix technical issues and improve your search visibility.

Technical SEO Audit Checklist

Follow this checklist to ensure your site is technically optimised for search engines and users. Here are the seven key factors you need to check:

  1. Ensure your site is secure (HTTPS)
  2. Improve website speed and performance
  3. Check mobile-friendliness
  4. Optimise site structure and internal linking
  5. Audit your indexability and crawlability
  6. Fix broken links and redirects
  7. Implement structured data and schema markup

Each of these factors plays a critical role in your site’s technical health. Even one overlooked issue can impact rankings, site speed, or user experience. Let’s break down each item and see how to check and fix them.

1. Ensure Your Site is Secure (HTTPS)

Would you use a website that isn’t secure? Probably not – and neither would most people. Google feels the same way, which is why HTTPS is a ranking signal, and sites without it get buried deep in search results, making them harder to find.

To stay competitive and gain people’s trust, you need to make sure your site is fully secured with HTTPS. Is your website secure?

If your site isn’t fully secure, don’t worry – fixing it is straightforward.

2. Improve Site Speed and Performance

A slow website frustrates users and makes them leave before engaging with your content. Google considers page experience a ranking signal, meaning poor speed and performance can push your site lower in search results.

A well-optimised site keeps visitors happy and improves search visibility. Is your site fast, stable, and responsive?

If your scores aren’t where they should be, don’t worry – there are ways to fix them.

3. Check Mobile-Friendliness

Did you know that over 60% of web traffic now comes from mobile devices? Because of this shift, Google uses mobile-first indexing, meaning it primarily uses the mobile version of a website’s content for crawling, indexing, and ranking in search results.

A poorly optimised mobile site can hurt both rankings and user experience. Is your site easy to navigate, fast to load, and fully functional on all devices?

If your site isn’t mobile-friendly, don’t worry – there are simple fixes to improve it.

4. Optimise Website Structure and Internal Linking

A confusing website structure makes it hard for users to navigate and difficult for search engines to understand your content. Poor internal linking can leave important pages undiscovered, hurting both rankings and user experience.

A well-structured site ensures smooth navigation and better search visibility. Is your content easy to find for both users and search engines?

If your site’s structure is messy, don’t worry – fixing it is easier than you think.

5. Audit Your Indexability and Crawlability

If search engines can’t crawl or index your pages, they won’t appear in search results at all. Misconfigured robots.txt files, noindex tags, or crawl inefficiencies can prevent important content from being discovered and ranked.

Ensuring proper indexability helps Google discover and rank your pages effectively. Is your content accessible, or is it stuck hidden from search results?

If key pages aren’t getting indexed, don’t worry – there are ways to fix it.

6. Fix Broken Links and Redirects

Broken links frustrate users and waste crawl budget. Meanwhile, poorly managed redirects can slow down your site and dilute ranking signals. If your links don’t work properly, both visitors and search engines will hit dead ends.

Fixing broken links and redirects keeps your site smooth and SEO-friendly. Are your links guiding users and search engines correctly, or are they leading to dead ends?

If your site has broken links or mismanaged redirects, don’t worry – fixing them is simple.

7. Implement Structured Data and Schema Markup

Search engines rely on structured data to better understand your content and enhance search results. Without schema markup, your pages may miss out on rich snippets like star ratings, FAQs, and product details that improve visibility and click-through rates.

Adding structured data helps search engines interpret your content and makes your pages stand out in SERP. Is your content optimised for enhanced search features?

If your site isn’t using structured data, don’t worry – implementing it is simple.

What Is the Best Tool to Perform a Technical SEO Audit?
