How Screaming Frog Fits in Your SEO Workflow
Screaming Frog complements tools like Google Search Console, Semrush, and Ahrefs by focusing specifically on technical diagnostics. Here’s where it fits in:
- Before a site migration: Audit the full site and export URL maps
- During monthly SEO health checks: Spot crawlability and indexability issues early
- For content audits: Analyze titles, meta descriptions, headers, and status codes
- In reporting: Visual crawl maps help clients understand structural issues
Using Screaming Frog with GA & GSC
When integrated with Google Analytics and Google Search Console, Screaming Frog provides even deeper insight:
- Overlay crawl data with bounce rate, time on page, and goal completions
- Identify high-traffic pages missing meta tags or with broken links
- Filter for pages that are indexed but not performing
This makes it much easier to connect technical SEO issues with real performance data.
Best Practices & Tips for Beginners
- Start with a basic crawl using \”Spider\” mode to understand the layout
- Filter for 4xx, 5xx status codes immediately
- Use the \”Duplicate\” tab to find repeated meta titles or H1 tags
- Export data to Excel or Google Sheets for analysis or reporting
- Exclude parameters or sections you don’t want crawled to speed things up
Real-World Case Example
A mid-sized furniture webshop with 6,000+ URLs used Screaming Frog before launching a new design. The crawl revealed:
- 114 duplicate meta titles
- 295 internal redirect chains (some with 3+ hops)
- 38 canonical tag mismatches
- Over 100 URLs blocked by robots.txt unintentionally
By fixing these issues before launch, the site retained its rankings and improved crawl efficiency by over 35%.
Content Audits with Screaming Frog
Beyond technical fixes, Screaming Frog can help optimize content:
- Identify thin content pages (e.g., less than 300 words)
- Spot missing H1s or unoptimized headings
- Find pages with overly long or duplicated meta descriptions
- Highlight pages with no internal links pointing to them
This is especially useful for preparing content refreshes or consolidation projects.
Visualizing Your Site Architecture
Screaming Frog’s crawl visualizations help you spot hierarchy issues, deep content, and silo problems. These include:
- Crawl Tree Graph: Displays the entire site structure in a branching diagram
- Force-Directed Crawl Diagram: A dynamic map of internal links and crawl depth
These visualizations are especially useful in client reports or when collaborating with developers.
Pricing & Access
Screaming Frog offers a generous free version that lets you crawl up to 500 URLs. The paid version unlocks unlimited crawling and advanced features for £199 per year, per license. It’s a lightweight investment for the amount of SEO control you gain.
