Screaming Frog SEO Spider is a website crawler used by SEO professionals to inspect site structure and identify technical issues. It can help teams find broken links, review page titles and meta descriptions, analyse directives, and export data for further investigation.
A crawl is a diagnostic snapshot—not a complete SEO audit by itself. Results depend on the crawl configuration, access permissions, JavaScript rendering settings, and the pages the tool can discover.
1. Configure the Crawl
Download the tool from the official Screaming Frog SEO Spider website. Enter the website URL, select appropriate crawl settings, and consider whether you need to crawl subdomains, render JavaScript, or include XML sitemaps. For large sites, manage crawl speed and resource use carefully.
2. Find Broken Links and HTTP Errors
Review response codes and inspect internal links that lead to 404 pages, server errors, or unexpected redirects. Check the source pages linking to those URLs before fixing them. A 404 is not always a problem—for example, a deliberately removed page may correctly return 404 or 410 if there is no relevant replacement.
3. Review Page Titles and Meta Descriptions
Export missing, duplicated, or unusually long titles and descriptions for review. Use the findings to identify pages that need clearer, more distinctive wording. Do not change every title simply to fit a fixed character count; clarity, relevance, and how the title may display are more important than a universal length rule.
4. Inspect Heading Structure
Review page headings to find missing or duplicated elements and pages whose content structure is difficult to understand. A crawler can flag patterns, but a human review is still needed to decide whether headings accurately describe the page and help visitors navigate the content.
5. Check Canonical Tags and Indexability
Inspect canonical URLs, robots directives, and indexability status. Look for accidental noindex directives, canonical targets that do not match the intended page, and important pages that are blocked from crawling. Do not remove directives or change canonicals in bulk without confirming the site’s intended indexing strategy.
6. Review Redirects
Find redirect chains, loops, and internal links that point to redirected URLs. Update internal links to the correct final destination where appropriate. Redirects can be necessary after a URL change, so the goal is not to eliminate every redirect but to keep them deliberate and functional.
7. Audit Images and Alt Text
Identify large image files and missing alt attributes. Check whether the image needs compression or resizing, and write useful alt text for informative images. Decorative images may use empty alt text; avoid stuffing keywords into descriptions.
8. Analyse Internal Links and Crawl Depth
Use internal link and crawl-depth reports to locate important pages that are difficult to reach or have few relevant internal links. There is no universal rule that every important page must be within exactly three clicks. Prioritise a logical, usable structure that makes key content easy to discover.
9. Compare URLs With XML Sitemaps
Check whether important, indexable canonical URLs are included in the XML sitemap and whether sitemap URLs return the expected status. Sitemaps help discovery but do not guarantee indexing. Investigate unexpected exclusions rather than automatically adding every URL.
10. Connect Other Data Sources When Useful
Depending on your licence and configuration, integrations can combine crawl data with sources such as Google Analytics or Search Console. This can help identify important pages with technical issues or pages that receive search impressions but need content review. See the official tool documentation and features for current capabilities and setup details.
Turn Crawl Findings Into an Action Plan
- Export issues and group them by type and business impact.
- Prioritise problems affecting important pages, users, or search accessibility.
- Verify each issue manually before making changes.
- Implement fixes in a controlled way and preserve necessary redirects and metadata.
- Run a follow-up crawl to confirm the result.
Common Mistakes to Avoid
- Treating every warning as a critical error.
- Changing canonical tags or robots directives without checking intent.
- Assuming a crawl proves a page is indexed by Google.
- Making bulk title or URL changes without reviewing their effect.
- Ignoring user experience while focusing only on technical reports.
Final Thoughts
Screaming Frog is useful for discovering technical patterns at scale, but the findings need interpretation and prioritisation. Combine crawler data with Search Console, analytics, and manual review to build a reliable action plan. For additional help, explore our SEO services and SEO packages.
