In digital marketing, visibility and performance work in concert. And if you want to keep a flawless, search engine friendly site, performing a technical audit is necessary. But what is a technical audit? And why should it be a priority for every website owner?
A technical audit is the exhaustive process of reviewing a website’s infrastructure and backend elements to make sure they are optimized for search engine crawling, indexing and performance.
The technical audit focuses on the technical elements about the site, and not about content or design. For example, elements may include loading speed, mobile usability, crawl errors, and site structure.
Understanding Technical Audits in SEO
A technical SEO audit is the in-depth analysis of a website’s technical infrastructure — including speed, crawlability, mobile usability, and indexability — to ensure it meets search engine guidelines and user expectations. It doesn’t focus on content or design, but rather on how well your site functions behind the scenes — covering aspects like speed, mobile usability, structured data, and overall crawlability. Understanding how these elements impact SEO is key to maintaining a healthy, visible, and competitive website.
Why Technical Audits Are Crucial for Your Website?
Before looking at the checklist, it is important to recognize that a technical audit is more than another task within the SEO process. Even if your site has content that is better than anyone else, if search engines cannot crawl and index your pages, you will not be ranking.
A technical SEO audit helps uncover the underlying technical issues that prevent pages from being indexed and ranked — such as broken links, slow page speed, mobile incompatibility, or poor Core Web Vitals performance.
- Broken internal links
- Poor page speeds
- Duplicate content
- Poor mobile optimization
- Incomplete structured data
- 503 errors or other server issues.
When these issues are discovered and fixed, your site is capable of generating additional visibility, user experience, and conversions.
Website Performance Analysis: The Foundation of a Technical Audit
A successful audit generally hinges on an analysis of website performance. Performance analysis is the evaluation of how your website performs in real time, that is, how fast it loads, and how well it handles user-generated activities.
Our primary goal is to use tools like Google PageSpeed Insights, GTmetrix, and Lighthouse to evaluate the following core metrics:
- First Contentful Paint (FCP)
- Time to Interactive (TTI)
- Largest Contentful Paint (LCP)
- Cumulative Layout Shift (CLS)
Websites with slow-loading times frustrate users and are penalized by search engines. Therefore, during your performance analysis, you should look for server response times, image optimization, JavaScript minification, and caching.
Step-by-Step Guide to Conduct a Technical Audit
Let’s get into the step-by-step process:
1. Crawl your site
Start by crawling your website with something like Screaming frog or Sitebulb. When you crawl your entire website, it will tell you everything about broken links, duplicate pages, redirecting pages, sitting page, tags missing etc.
You will want to check for:
- Status codes (404 errors, 301 redirects)
- Canonical tags
- Meta titles and descriptions
- H1 tags and H2 tags
- Crawl depth
This step provides a high level overview of the site health audit tools and allows you to discover issues at scale.
After crawling, make sure your webpages are indexable by search engines. For example, check your robots.txt file, XML sitemap, and meta robots tags.
Ask yourself:
- Are important pages accidentally blocked in robots.txt, or marked with noindex tags that prevent indexing?
- Is your sitemap submitted in the Google Search Console?
- Are there pages wrongly marked as no-index?
Search engines rely on such settings to understand how your site is to be interpreted.
3. Reviewing the Site Architecture
Well-structured and clean site architecture will benefit both SEO and user navigation. The sites need to have a hierarchy with their content organized into categories and subcategories.
Some of the best practices are:
- A shallow click depth (never more than 3 clicks to reach a page)
- A proper use of breadcrumb navigation
- Internal linking to pass some authority
- Flat site structure when suitable
Proper site architecture can enable Google bots to crawl pages seamlessly and enhance overall discoverability.
4. Mobile Usability Check
Due to mobile first indexing, the mobile optimization is no more an option. You can check the performance and look of your website over all the devices with the help of Google’s Mobile-Friendly Test.
Look For:
- Responsive design
- Readable fonts
- Buttons that have space between them
- No horizontal scroll
- Fast mobile loading
Mobile usability should be treated as a priority during technical audits, ensuring proper ranking and user engagement. Following mobile SEO checklists can streamline this process and improve your mobile performance metrics.
5. Focus on Speed Optimization
One of the most crucial ranking elements is website speed. Use browser caching, minify CSS and JavaScript files, enable lazy loading, and compress images.
Load times can be significantly impacted by image formats (such as WebP), hosting companies, and content delivery networks (CDNs). Keep in mind that conversions and user retention can significantly decline with every second of delay.
6. Examine HTTPS and Security
Ensure your site has HTTPS and that resources are served securely. Browsers marking HTTP sites as insecure can erode credibility.
Items on the list are:
- SSL certificate installed
- Mixed content fixed
- Switching safely from HTTP to HTTPS
- Collection of valid security headers (such as HSTS and X Frame Options)
Security enhances visitor and search engine trust as well as safeguards data. You may also consider tailored software development solutions to implement advanced security configurations.
7. Check Structured Data and Schema Markup
Structured data within your content helps search engines understand it better. Apply schema markup to enhance the likelihood of rich results in search pages, such as reviews, recipes, FAQs, and events.
- Utilize Google’s Rich Results Test to:
- Identify missing or incorrect markup.
- Check that all properties are correctly defined.
- Correct any spelling mistakes.
Structured data usage is among the top methods to increase visibility and clicks.
8. Locate Duplicate Content
Duplicate content may confuse search engines and lower the authority of your page. Utilize tools such as Siteliner or Copyscape to find duplicate pages.
Also, search for:
- Duplicate title tags
- Various URL structures, including and excluding www
- Unpredictability in trailing slashes
- Non-canonical, indexable pages
Utilize canonical tags and 301 redirects if necessary to resolve problems.
9. Verify the Web Basics
Core Web Vitals, being important to user experience, are included in Google’s algorithm for rankings.
- The metric is LCP (Largest Contentful Paint).
- FID is an acronym for First Input Delay.
- CLS is an acronym for Cumulative Layout Shift.
You can find more about how actual users interact with your site by examining these metrics. Take the initiative to ensure that all scores fall in ranges that Google suggests.
10. Confirm External and Internal Links
Broken links are not good for SEO or user experience. Utilize auditing tools to search for:
- 404 errors
- Broken outbound links
- Loops that redirect
- Orphaned pages without internal links
Besides making your site more crawlable, repairing broken links keeps your content relevant and reliable.
