In today’s online world, your website is one of your strongest assets. But just having a website isn’t enough – you need to make sure it performs well in search engines, delivers a good experience to users, and drives measurable results. That’s where a website SEO audit checklist comes in.
Here’s a practical, step-by-step guide you can follow to perform a full website SEO audit checklist. Whether you’re doing this for your own site or for a client, these 15 steps will help you find issues, prioritize fixes, and create an action plan for sustainable growth.
Step 1 – Clarify business goals & KPIs
Before diving into technical details, stop and ask: What are we trying to achieve with our website? Are you seeking more leads? More e-commerce sales? More brand exposure? Define your key performance indicators (KPIs) such as the number of conversions, contact form submissions, or email sign-ups. Aligning your SEO audit with business goals ensures your work makes a direct impact.
2 – Check analytics & access
Make sure you have full access to tools like Google Analytics 4, Google Search Console and any other tracking systems. Confirm that conversion tracking is working correctly, and your analytics data is accurate. Without reliable data you cannot measure the effect of your audit and optimisations.

Step 3 – Crawl the site (technical baseline)
Use a site-crawler tool (for example, Screaming Frog SEO Spider) to scan your website and discover issues like broken links, duplicate content, redirect chains, and pages with improper HTTP status codes. A clean technical baseline is essential for an effective technical SEO audit.
What to look for
- 4xx/5xx error pages
- Redirect loops (301s/302s)
- Duplicate content via canonical tags
- Pages blocked from indexing by robots.txt or meta tags
Step 4 – Review robots.txt & XML sitemap
Check if your robots.txt file correctly allows search engines to crawl your important pages. Ensure you have an up-to-date XML sitemap submitted to Search Console and listed in your robots.txt. Omitting this means search engines may miss key pages.
Step 5 – Audit site architecture & URL structure
A well-organized site structure makes it easier for users and search engines to navigate. Ensure your key pages are reachable within a few clicks from the homepage, URLs are readable and descriptive (avoid long strings and numbers), and the site uses clear categories or folders.
Step 6 – Core Web Vitals & page speed optimization
Performance matters: site speed and Core Web Vitals (e.g., LCP, CLS, INP) affect user experience and may influence rankings. Use tools like Google PageSpeed Insights or Lighthouse to check. Compress images, enable browser caching, optimise server response time, and remove render-blocking resources to improve performance.
Step 7 – Mobile usability
More users access websites on mobile devices than ever before. Make sure your pages are mobile-friendly: responsive layout, proper viewport settings, tap targets appropriately sized, and mobile-page speed optimized. A mobile usability issue can seriously reduce your traffic and conversions.
Step 8 – On-page SEO basics on this website SEO audit checklist
Now let’s focus on your page content and metadata. Each page should have:
- A unique and descriptive title tag
- A compelling meta description that persuades users to click
- One H1 tag aligned with your target keyword
- Proper heading structure (H2, H3) to organise content
Ensure you incorporate your primary keyword naturally (for example, “website SEO audit checklist”) and related phrases like “technical SEO audit”, “on-page SEO audit”.
Step 9 – Content quality & relevance
The best-performing pages provide value, depth, and relevance. Review your content: Are there pages with thin content or outdated information? Do pages align with what the user is searching for (search intent)? Refresh old pages, merge similar pages, and create new content where necessary. Good content is central to your on-page SEO audit.

Step 10 – Keyword mapping & search intent
Map each important page to a target keyword and ensure that the keyword aligns with what someone is looking to find. Identify long-tail keywords (for example, “how to perform a website SEO audit checklist”) and avoid keyword cannibalization (multiple pages competing for the same term). Correct keyword mapping helps you target the right users at the right stage.
Step 11 – Internal linking & orphan pages
Internal linking helps distribute authority and guides users through your site. Make sure important pages are linked from other relevant pages with descriptive anchor text. Identify “orphan” pages (pages with no inbound internal links) and fix this. This part of your audit ensures all valuable pages are discoverable.

Step 12 – Structured data & rich snippets
Use structured data (Schema.org) to help search engines understand your content and display rich results. Depending on your site, you could add product schema, FAQ schema, article schema or local business schema. This portion links to your larger SEO audit by enhancing visibility in search results.
Step 13 – Backlink profile & off-page signals
While on-page and technical audit steps are important, off-page SEO matters too. Review your backlink profile: quality of referring domains, anchor-text diversity, signs of spammy links. A healthy link profile supports ranking efforts and signals authority to search engines.
Step 14 – Local SEO (if applicable)
If your business serves a local area, check the state of your local SEO. This includes your Google Business Profile, consistency of NAP (Name, Address, Phone) across directories, local citations, and customer reviews. A local SEO audit is crucial for brick-and-mortar, service-area or geographically-targeted businesses.
Step 15 – Prioritise issues & create action plan to follow this website SEO audit checklist
An audit alone isn’t enough — action is what drives results. For each issue found, assess effort vs. impact. Prioritize quick wins (e.g., fix broken pages, update meta tags) and build a 30-60-90 day roadmap. Assign owners, set deadlines, and track KPIs. Then repeat audits regularly to monitor progress.
Putting it all together – audit schedule and next steps
Once your audit is done, set a routine:
- Monthly crawl and technical check
- Weekly review of analytics and search console for anomalies
- Quarterly content review and backlink check
By embedding this audit workflow into your SEO strategy, you ensure continuous improvement and avoid falling behind.
