Keywords Everywhere vs Sitebulb

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.

Sitebulb is a website auditing crawler from a UK-based company, built for technical SEOs and agencies. Like other crawlers it scans a site the way a search engine would, but its focus is on explaining and prioritizing issues rather than presenting raw data, which makes findings easier to understand and to communicate to clients and developers.

Each audit produces Hints: prioritized issues with plain-language explanations of why they matter and how to fix them. Visual crawl maps, charts and reports show site architecture, internal linking and indexability at a glance. Sitebulb renders JavaScript with a headless Chrome engine and compares rendered and raw HTML, and audits cover structured data, accessibility, page speed, international SEO and duplicate content. The desktop app runs on Windows and Mac with Lite and Pro licenses limited by URLs per audit, while Sitebulb Cloud crawls very large sites on remote servers and lets teams share audits.

Sitebulb fits SEOs and agencies who want actionable, explainable audits and client-ready visuals. Screaming Frog offers more flexible custom extraction and configuration and remains the default for power users, so many professionals use both. Desktop crawls of large sites consume significant memory, and the cloud version is a sizeable step up in price. Lumar and Botify target enterprise-scale continuous monitoring, while Semrush and Ahrefs site audits are simpler options bundled with broader SEO suites.
