Screaming Frog SEO Spider

Screaming Frog SEO Spider is a powerful desktop application used by SEO professionals and website owners to perform in-depth technical audits. It crawls your entire site just like a search engine bot, identifying errors, issues, and optimization opportunities across all pages — making it a must-have tool for improving site health and search engine visibility.

Whether you're working on a small blog or managing an enterprise-level website, this tool helps uncover what’s working, what’s broken, and what can be improved.

What Is Screaming Frog SEO Spider?

Screaming Frog SEO Spider is a website crawler that scans websites for key SEO elements, similar to how Googlebot or Bingbot would. It collects data on:

Title tags and meta descriptions
Response codes (like 404 or 301)
Broken links (internal and external)
Duplicate content
Canonical tags
Page depth and internal linking
Redirect chains
Image optimization issues

This data helps SEOs fix problems that can affect rankings or user experience.

Installing and Setting Up the SEO Spider

To get started, download the application from the official site: www.screamingfrog.co.uk/seo-spider. It's available for Windows, macOS, and Ubuntu.

Once installed:

Open the software.
Enter your website URL in the search bar.
Click “Start” to begin crawling.

The free version allows crawling of up to 500 URLs, while the paid version offers unlimited crawling and advanced features.

Performing a Site Audit

Once the crawl is complete, you can begin analyzing results across multiple tabs:

1. Internal Tab

Lists every internal URL found. You’ll see status codes, page titles, meta descriptions, and more — allowing you to filter and sort by optimization criteria.

2. Response Codes

Find broken links (404), redirects (301, 302), and server errors. These issues should be fixed or redirected correctly to maintain SEO value.

3. Page Titles & Metadata

Identify missing, duplicated, or overly long page titles and meta descriptions. This is essential for on-page SEO optimization.

4. Content

Flag pages with low word counts or duplicate headers that may be affecting page quality scores.

5. Images

See which images are too large, missing alt attributes, or poorly optimized for speed and accessibility.

Using Advanced Features

For more in-depth analysis, Screaming Frog offers advanced tools:

XML Sitemap Generator: Automatically build or audit your sitemap for submission to search engines.
Custom Search Filters: Search pages for specific code, tags, or text snippets (like tracking scripts or old content).
JavaScript Rendering: Crawl websites that require JS execution to load content, such as SPAs or dynamic menus.
Integrations: Connect Google Analytics, Google Search Console, and PageSpeed Insights to enrich your crawl data.

These features turn Screaming Frog into a complete technical SEO command center.

Exporting and Reporting

After your analysis:

Export data in CSV or Excel format.
Share reports with developers or content teams.
Use filters to create issue-specific reports (e.g., only duplicate titles or 404s).

The ability to extract structured data like headings, hreflang tags, schema markup, and anchor text makes it extremely valuable for SEO audits.
