Screaming Frog SEO Spider is the industry-standard site crawler used by professional SEOs worldwide. This guide covers how to run a complete technical SEO audit using Screaming Frog, from initial setup to interpreting the results.
Step 1: Configure Your Crawl Settings
Before crawling, configure these settings in Screaming Frog:
- Mode: Spider (default) for standard audits
- Configuration → Spider: Check “Crawl all subdomains” if applicable
- Configuration → Rendering: Enable JavaScript rendering for JS-heavy sites (paid version)
- Configuration → Exclusions: Exclude query strings, session IDs, or irrelevant URL patterns
- Speed: Set crawl speed appropriate to server capacity — slower for shared hosting
Step 2: Run the Crawl
Enter your domain URL and click Start. Screaming Frog crawls every URL it discovers. During the crawl you can see URLs being added in real time. For large sites (10,000+ pages), crawls may take 30-60 minutes.
Step 3: Key Reports to Check
| Report | What to look for | Priority |
|---|---|---|
| Response Codes → 4xx | Broken pages returning 404 errors | High |
| Response Codes → 3xx | Redirect chains and loops | High |
| Page Titles → Missing | Pages without title tags | High |
| Page Titles → Duplicate | Multiple pages sharing same title | High |
| Meta Description → Missing | Pages without meta descriptions | Medium |
| H1 → Missing or Duplicate | Missing or duplicate H1 tags | Medium |
| Images → Missing Alt Text | Images without descriptive alt attributes | Medium |
| Canonicals → Non-Canonical | Pages pointing to a different canonical | Medium |
Step 4: Prioritise Issues
Focus on high-priority issues first: broken pages (404s), redirect chains (3xx), and missing title tags directly impact user experience and rankings. Meta descriptions and H1 issues are important but less immediately impactful.

How to Analyze Internal Links with Screaming Frog
Short answer: Use the Internal Links tab in Screaming Frog to assess your website’s internal linking structure.
Internal linking is crucial for SEO as it helps search engines understand the hierarchy and relevance of your content. To analyze internal links using Screaming Frog, simply navigate to the Internal Links tab after you’ve crawled your site. Here, you can view all the internal links pointing to each page, the number of links, and the anchor text used. This information allows you to identify pages that may lack sufficient internal links or to discover opportunities to enhance the linking structure.
Additionally, reviewing the internal linking structure can help you identify orphaned pages—those that aren’t linked to from any other pages. Fixing these can improve your site’s overall SEO performance as it allows search engines to discover and index more of your content efficiently.
Exporting Data for Further Analysis
Short answer: Use the export feature in Screaming Frog to download data for detailed analysis.
After completing your audit with Screaming Frog, exporting the data can significantly enhance your analysis. You can export various reports, including SEO issues, page titles, headers, and response codes, into CSV or Excel formats for further manipulation. This is particularly useful for creating custom reports or sharing findings with your team.
Once the data is exported, you can perform deeper analysis using spreadsheet functionalities. For example, you can sort, filter, and create pivot tables to gain insights into patterns or recurring issues. This capability allows for a more granular understanding of your site’s SEO health and can help prioritize actions based on data-driven decisions.
