Keywords Everywhere vs Screaming Frog SEO Spider

Keywords Everywhere is a browser extension for Chrome and Firefox that shows keyword data directly on the pages marketers already use. When you search Google, it displays search volume, cost per click and competition next to the query, along with panels of related and long-tail keywords, and similar overlays appear on YouTube, Amazon, Bing and other sites.

Beyond the search overlay, it offers trend charts, metrics for the URLs ranking on a results page, on-page keyword density and page analysis, YouTube channel and video metrics, backlink data and bulk keyword exports. It is sold on credits: each keyword lookup consumes credits, and plans are bought annually in tiers starting with Bronze, so cost depends on how much data you pull. That makes it far cheaper than a full SEO suite for light use, but harder to budget when every search consumes credits.

The tool suits bloggers, content writers, small business marketers and YouTubers who want quick volume checks while browsing without paying for Ahrefs or Semrush. The data is estimated, credits can run out quickly, and it lacks rank tracking, site audits and deep competitor analysis. Ahrefs and Semrush are the full suites, Ubersuggest is a cheaper all-round tool, and Google Keyword Planner is free for basic volume ranges.

Screaming Frog SEO Spider is a desktop crawler used by nearly every technical SEO. It crawls websites like a search engine to find broken links, redirect chains, duplicate titles and descriptions, missing tags, thin pages, canonical and hreflang problems, orphan pages (with GA/GSC data), structured data validation and more. The paid licence adds JavaScript rendering, scheduling, custom extraction with XPath and regex, and API integrations including LLMs for content analysis.

It is sold as an annual licence rather than SaaS, runs on Mac, Windows and Linux, and handles sites of hundreds of thousands of URLs with enough memory. Sitebulb is the more visual alternative; cloud crawlers like Lumar serve enterprises.

The tool is made by Screaming Frog, a UK search marketing agency, and the licence is priced per user per year with no limit on the number of sites you crawl. Regular version updates add features such as crawl comparison, segmentation and custom extraction with AI providers, so renewing keeps the tool current. Many SEO teams pair it with Google Search Console data and the company's separate Log File Analyser for a complete technical picture.
