Screaming Frog

Freemium

Screaming Frog SEO Spider is a desktop website crawler developed by Screaming Frog for technical SEO auditing. It follows links and collects response codes, titles, metadata, canonicals, directives, headings, structured data, duplicate signals, and other page-level information, with configurable rendering, extraction, integrations, and bulk exports. It is best for SEO specialists and developers diagnosing large sites, migrations, broken links, redirect chains, indexation controls, or template problems that are difficult to spot page by page.

What it does

Screaming Frog SEO Spider is a desktop crawler that walks through a website the way a search engine bot would, collecting page-level data into a sortable, filterable, exportable table. For every URL it records status codes, titles, meta descriptions, headings, canonicals, robots directives, word counts, internal links, and structured data, exposing problems that are invisible page by page: redirect chains, orphaned pages, duplicate titles, broken links, accidental noindex tags. It can render JavaScript, compare staging against production, extract custom data with XPath, and pull in Search Console and Analytics data per URL via API. The free version crawls 500 URLs; a paid license removes the cap and unlocks configuration, scheduling, and integrations.

Where it fits

Screaming Frog handles the technical audit stage of SEO, generating the issue lists that developers fix and that tools like Search Console later confirm as resolved.

Core features

  • Full-site crawling with response codes, metadata, and directives
  • JavaScript rendering for client-side content auditing
  • Redirect chain, broken link, and canonical analysis
  • Custom extraction with XPath and regex
  • Search Console and Analytics API integration per URL

Best for

  • Technical SEO specialists auditing site structure and indexability
  • Teams validating migrations and redirect maps before launch
  • Developers diagnosing template-level metadata problems at scale

Beginner notes

  1. The free 500-URL limit covers small sites and learning; you only need the license once you audit larger properties regularly.
  2. Crawl data tells you what is wrong, not what matters most; prioritize issues by the traffic and revenue of affected pages.
  3. Lower the crawl speed for small or shared hosting, because an aggressive crawl can noticeably slow a production site.
