Step-by-Step SEO Audit Process
1. Website Crawlability and Indexing
1.1 Conduct a Comprehensive Site Crawl
Process:
- Utilize advanced crawling tools like Screaming Frog SEO Spider, DeepCrawl, or Sitebulb.
- Configure the crawler to emulate search engine behavior, including respecting robots.txt directives.
- Analyze the crawl data to identify:
- Broken links (4xx errors)
- Server errors (5xx)
- Redirect chains and loops
- Duplicate content issues
- Missing or duplicate meta tags
- Orphaned pages
Example: A mid-size e-commerce site discovered through a deep crawl that 30% of their product pages were orphaned due to a faulty internal linking structure. Fixing this issue led to a 25% increase in indexed pages and a subsequent 15% boost in organic traffic.
1.2 Evaluate Robots.txt and XML Sitemaps
Process:
Review your robots.txt file for unintentional blocking of important resources.
Ensure your XML sitemap:
- Is up-to-date and includes all important pages
- Excludes non-canonical, noindex, and low-value pages
- Is referenced in your robots.txt file
- Has been submitted to Google Search Console and Bing Webmaster Tools
Tip: Use dynamic XML sitemaps that automatically update as your content changes to ensure search engines always have access to your latest pages.
1.3 Analyze Indexation Status
Process:
- Use the “site:” operator in Google (e.g., site:example.com) to get a rough estimate of indexed pages.
- Compare this with your actual page count and XML sitemap entries
- Investigate discrepancies using Google Search Console’s Index Coverage report.
- Address any “noindex” tags or canonical issues preventing important pages from being indexed.
Case Study: A news website found that their article archive, containing thousands of valuable evergreen articles, was inadvertently blocked from indexing. Resolving this increased their indexed pages by 40% and organic traffic by 35% within three months.

Process:
