Fortunately, at each step in the process, these issues can be identified with time. The goal of this guide is to walk you through each step of the process.
The first step of identifying these issues is to take a look at your website and check the basics. This includes simple checks such as page load times. Then these audits can take on more complex forms. Here is the big picture of the process we’re about to outline.

What Is a Technical SEO Audit?
Everything related to your website that search engines crawl, index, or rank is reviewed in a technical SEO audit. It clears the way for your most important site pages to be easily ranked, identifies hidden problems, such as slow pages and broken links, and uncovers indexing issues.
A thorough technical audit usually focuses on:
- Website crawling
- Crawlability and indexability
- URL structure
- Internal links
- Redirects
- Canonical tags
- XML sitemaps
- Robots.txt
- Mobile usability
- Page speed
- Core Web Vitals
- HTTPS and security
- Structured data
A strong technical foundation is what allows your content and SEO efforts to actually perform.
How to Do a Technical SEO Audit
This guide outlines the technical seo audit process in 7 simple steps, starting with a full website crawl followed by progressive scrutiny.
Step 1: Perform a Website Crawl Analysis
Run a crawling tool across your site to identify URLs and flag common technical problems. A website crawl analysis should surface:
- Broken internal links
- Broken external links
- Redirect chains and redirect loops
- Duplicate URLs
- Missing page titles or canonical tags
- Pages returning server errors
- Orphan pages
- Pages with unusual crawl status
Start with your most important pages. Fixing errors on your revenue and service pages matters most because they carry the highest impact.
Step 2: Check Crawlability and Indexability
Crawling and indexing determine whether search engines have the ability to access and store pages for presentation to the user. Check for:
Robots.txt audit and structural checks:
- Pages blocked by robots.txt
- Noindex directives on important pages
- Incorrect canonical tags
- Server errors
- Redirected URLs
- Duplicate pages
- Important pages with weak internal links
The aim is straightforward: search engines access your crucial pages and content, memorize the data, and refrain from accessing your sensitive data.
Step 3: Conduct a Google Search Console Audit
A Google Search Console audit shows Google’s data on your site’s health. Start with your Page Indexing report to discover specifically excluded search pages.
Also review:
- Core Web Vitals
- HTTPS reports
- Sitemaps
- Mobile-related issues
- Manual actions
- Security issues
- Search performance trends
Page Indexing guides you to fix certain high-value pages as opposed to equally fixing every URL.
Step 4: Complete an XML Sitemap Audit
An XML sitemap audit guides search engines to find and index your essential pages. Build your sitemap with live, canonical URLs with successful responses.
Check for:
- Redirected or broken URLs
- Non-canonical URLs
- Noindex pages
- Duplicate URLs
- Incorrect URL versions (http vs. https, www vs. non-www)
- Missing important pages
Replace redirects with the final canonical URL, then submit the sitemap to Google again.
Step 5: Perform a Robots.txt Audit
An audit of your robots.txt assures search engine crawlers have the correct instructions. Rough robots.txt instructions can easily, unintentionally block important pages.
Review the file for:
- Unnecessary disallow rules
- Important pages blocked from crawling
- Incorrect directory restrictions
- Conflicting instructions
- A reference to your sitemap
Note: Robots.txt gives instructions on crawling. It does not give instructions on indexing. The two need separate checks.
Step 6: Review Website Performance
Website speed and SEO go hand in hand. Pay attention to:
- Core Web Vitals
- Large image files
- Unused JavaScript
- Render-blocking resources
- Slow server response times
- Excessive third-party scripts
- Browser caching and image optimization
High-value, traffic-landing pages and templates should be optimized first.
Step 7: Check Site Architecture and Internal Links
A good site structure means an easy site for both users and search engines to utilize.
- Orphan pages
- Excessive click depth
- Broken internal links
- Weak contextual links
- Unclear navigation
- Duplicate URL paths
Keep page layouts logical and meaningful. Place important pages a few clicks away from the home page.

How to Report Technical SEO Audit Findings
A good audit report explains every finding using four points:
- Issue: What is wrong?
- Impact: Why does it matter?
- Affected URLs: Where does the problem occur?
- Recommendation: What should be changed?
Prioritize according to impact.
How Often Should You Perform a Technical SEO Audit?
There’s no single schedule that fits every site, larger, frequently updated websites need more frequent checks. Plan a full audit when:
- You launch a new website
- Your website redesigns or platform switch
- You change your URL structure
- Organic traffic drops unexpectedly
- You make major technical changes
- Search Console reports new problems
Small checks between major audits can catch errors before they can impact your website negatively.
Mistakes to Avoid During a Technical SEO Audit
- Ignoring Search Console data
- Engaging in no prioritization practices
- The robots.txt and noindex confusing practices
- Auditing once
- The mobile-specific check skipping practice
- Your website will experience technical issues after a redesign, switch of platforms or a migration.
Conclusion
A strong technical foundation forms the basis upon which the remainder of your SEO strategy rests. A technical SEO audit examines your site’s crawling, indexing, performance and architecture, and helps you address issues with your backend before they can impact your visibility. Use the checklist above as a starting point, key in on the issue with the greatest impact, and understand that this process will be an ongoing one.
FAQs
1. How long does a technical SEO audit take?
It depends on site size and complexity. A complete analysis of a site with many pages can easily take several days.
2. Do I need special tools to perform a technical SEO audit?
Yes, at the bare minimum, you will need a crawling tool and access to Google Search Console. Additional tools can be used for testing page speed, as well as validating structured data.
3. Can I perform a technical SEO audit without a developer?
You can identify most issues yourself. Implementing many of these fixes, particularly for site architecture, redirects, and structured data, will require the assistance of a developer.
4. What’s the difference between a technical audit and a full SEO audit?
A technical audit only looks at backend factors like crawling and indexing. A full SEO audit looks at content and keywords, and includes backlinks.
5. How do I know which issues to fix first?
Issues with the most valuable pages should be addressed first. For example, issues that cause indexing to be blocked or broken redirects that impact significant revenue pages should be addressed first, versus simple page fixes that will only impact a few users.
