SEO audits: How to conduct one that drives traffic growth [+ checklist]

At its core, an SEO audit is a step-by-step review of your website’s technical health, content quality, and search visibility. An SEO audit identifies technical, on-page, content, and link issues on a website. It helps SEO teams identify, prioritize, and fix the issues that block traffic, rankings, and, importantly, conversions. Businesses and SEO teams should create audits to identify opportunities that advance business goals and growth.

A modern audit goes beyond identifying issues that further traditional blue-check rankings in Google Search. With AI search reshaping how users discover brands, marketers now need to evaluate entity signals, brand visibility in AI answers, and how well their content performs in generative engines. In this guide, you’ll learn how to run an SEO audit that’s helpful in today’s search landscape. I’ve included clear steps, examples, and an SEO audit checklist to help SEO professionals at any skill level drive measurable traffic growth.

What is an SEO audit and why does it matter?

An SEO audit is a structured review of your website. SEO specialists conduct audits at regular intervals, such as quarterly or yearly. Sometimes third-party consultants conduct site audits to bring a fresh set of eyes to the project. The audit identifies the issues preventing your pages from ranking, being crawled, or converting. Then, the SEO strategist turns audit findings into a prioritized plan that directly supports traffic growth, lead generation, and pipeline.

Typically, an audit includes:

1. **Technical health**: This area covers crawlability, indexability, page speed, Core Web Vitals, structured data, and site architecture. Ensuring your site is crawlable and indexable is crucial for search engines to understand your content. A fast and mobile-friendly site with good Core Web Vitals scores can significantly improve your rankings. Structured data helps search engines understand your content better, leading to rich snippets and higher click-through rates.

2. **On-page SEO**: This includes metadata, headings, internal linking, and content quality. Metadata, such as titles and descriptions, should be optimized for target keywords and provide a clear preview of the page content. Proper use of headings (H1, H2, etc.) helps structure the content and improves readability. Internal linking ensures that users can navigate your site easily and that search engines can crawl all your pages. Content quality is essential; high-quality, original, and engaging content attracts users and signals to search engines that your site is authoritative.

3. **Content**: This area evaluates the relevance, originality, and freshness of your content. Content should be optimized for target keywords and user intent. Original and fresh content can attract more backlinks and keep users engaged.

4. **Link issues**: This includes both internal and external links. Internal links help users navigate your site, while external links can provide additional context and authority. Broken links, non-indexable links, and irrelevant external links can harm your site’s performance.

5. **Technical seo**: This area covers technical aspects such as canonical tags, XML sitemaps, robots.txt, and HTTPS implementation. Canonical tags help search engines understand which version of a page is the preferred one. An XML sitemap provides a list of all your site’s pages for search engines to crawl. A well-configured robots.txt file can prevent crawling of unnecessary pages, and HTTPS encryption is essential for security and rankings.

6. **AI and generative search**: Modern audits should also assess how well your site performs in AI and generative search. This includes evaluating entity signals, brand visibility in AI answers, and content that can be easily used by generative engines.

How to Run an SEO Audit Step-by-Step

1. **Define your goals**: Before starting the audit, define your objectives. Are you looking to improve rankings, increase traffic, or enhance conversions? Understanding your goals will help you prioritize issues and measure the success of your audit.

2. **Gather data**: Use tools like Google Search Console, SEMrush, Ahrefs, or Moz to gather data on your site’s technical health, rankings, traffic, and backlinks. This data will serve as the foundation for your audit.

3. **Analyze technical health**: Check your site’s crawlability and indexability in Google Search Console. Look for pages with crawl errors, indexing issues, or pages that are blocked by robots.txt. Evaluate your site’s speed and Core Web Vitals scores. Ensure that your site is mobile-friendly and has proper structured data implementation.

4. **Examine on-page SEO**: Review your metadata, headings, and internal linking. Make sure your titles and descriptions are optimized for target keywords and provide a clear preview of the page content. Check that your headings are properly structured and that internal links are functional and relevant.

5. **Assess content quality**: Evaluate the relevance, originality, and freshness of your content. Ensure that your content is optimized for user intent and target keywords. Look for duplicate content, thin content, or content that is outdated or irrelevant.

6. **Inspect link issues**: Check for broken internal links and non-indexable or irrelevant external links. Identify potential link opportunities, such as link building with high-authority sites or creating content that can attract backlinks.

7. **Review technical SEO**: Ensure that your canonical tags, XML sitemaps, robots.txt, and HTTPS are properly configured. Look for any technical issues that could be blocking your site from performing optimally.

8. **Evaluate AI and generative search**: Assess your site’s performance in AI and generative search. Check for entity signals, brand visibility in AI answers, and content that can be easily used by generative engines.

9. **Prioritize fixes**: Based on your audit findings, prioritize the issues that have the highest impact on your goals. Focus on fixing critical issues first, such as crawl errors, broken links, or pages with severe technical problems.

10. **Create an action plan**: Develop a detailed plan to address the prioritized issues. Assign responsibilities, set deadlines, and monitor progress regularly.

11. **Implement changes**: Make the necessary changes to your site based on the audit findings. This may involve technical fixes, content updates, or link building efforts.

12. **Monitor and measure results**: After implementing changes, monitor your site’s performance using the same tools you used during the audit. Track improvements in rankings, traffic, and conversions. Adjust your strategy as needed based on the results.
