In their own words
Screaming Frog SEO Spider
Screaming Frog SEO Spider crawls websites to audit more than 300 SEO issues and support improvements to search performance and user experience. It finds broken links and server errors, checks redirects, and flags page titles and meta descriptions that are missing, duplicated, or too long. For JavaScript-heavy sites, it can render pages with its integrated Chromium WRS, including sites using Angular, React, and Vue.js. Data extraction supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, with link-metrics integrations for Majestic, Ahrefs, and Moz. Crawls can be scheduled, automated from the command line, exported to destinations such as Google Sheets, and compared across runs or between staging and production. The free version costs nothing and allows 500 URLs per crawl; saving crawls, configuration, and advanced features are restricted. The paid version costs $279 a year per licence, with unlimited crawl size subject to allocated memory and storage. It runs on Linux, macOS, and Windows.
SEOTesting
SEOTesting measures the impact of SEO changes using Google Search Console data, with Google Analytics data available when connected. Its tests include time-based experiments, comparisons between test and control groups, and LLM tests; they can cover individual pages, groups of pages, or URL switches, and track organic traffic and ranking impact. Reports address click-through-rate opportunities, content insights, Search Console data, keyword cannibalization, and monthly SEO summaries. The platform also identifies pages receiving clicks from AI search and offers tools to find prompt patterns and measure AI-driven visits. Website monitoring can alert teams to XML sitemap and robots.txt changes. Connections include Google Search Console, optional Google Analytics 4 and Bing Webmaster Tools, and a Looker Studio connector. An API, MCP server, and Chrome extension provide additional ways to use its data and checks. The 14-day free trial includes full functionality for up to 30 sites and requires no credit card. Paid plans start at $50 a month for Single Site.
