What can you do with the SEO Spider Software?

Find Broken Links
Crawl a website instantly and find broken links (404s) and server errors. Bulk export the errors and source URLs to fix, or send to a developer.

Audit Redirects
Find temporary and permanent redirects, identify redirect chains and loops, or upload a list of URLs to audit in a site migration.

Analyse Page Titles & Meta Data
Analyze page titles and meta descriptions during a crawl and identify those that are too long, short, missing, or duplicated across your site.

Discover Duplicate Content
Discover exact duplicate URLs with an md5 algorithmic check, partially duplicated elements such as page titles, descriptions, or headings, and find low content pages.

Extract Data with XPath
Collect any data from the HTML of a web page using CSS Path, XPath, or regex. This might include social meta tags, additional headings, prices, SKUs, or more!

Review Robots & Directives
View URLs blocked by robots.txt, meta robots, or X-Robots-Tag directives such as ‘noindex’ or ‘nofollow’, as well as canonicals and rel=“next” and rel=“prev”.

Generate XML Sitemaps
With Screaming Frog you can quickly create XML Sitemaps and Image XML Sitemaps, with advanced configuration over URLs to include last modified, priority, and change frequency.

Integrate with Google Analytics
Connect to the Google Analytics API and fetch user data, such as sessions or bounce rate and conversions, goals, transactions, and revenue for landing pages against the crawl.

Crawl JavaScript Websites
Render web pages using the integrated Chromium WRS to crawl dynamic, JavaScript rich websites and frameworks, such as Angular, React, and Vue.js.

Visualise Site Architecture
Evaluate internal linking and URL structure using interactive crawl and directory force-directed diagrams and tree graph site visualizations.
