Keywords Everywhere

How it works

Keywords Everywhere installs as a browser extension for Chrome, Firefox, and Edge. After signing up and entering an API key, the extension overlays keyword metrics — monthly search volume, cost per click (CPC), and competition score — directly onto search engine results pages (SERPs), YouTube, Amazon, and other supported sites.

The extension also surfaces related keywords, People Also Search For (PASF) data, and long-tail keywords in the sidebar or within the results page. These suggestions are pulled from the extension's API and updated in real time as the user browses.

Paid features require a credit-based subscription or a one-time purchase of credits. The free version offers limited access to data, with paid tiers unlocking higher volume and additional sources.

Why it matters

Keywords Everywhere eliminates the friction of jumping between a keyword tool and the browser. Practitioners can evaluate demand signals, compare keyword variants, and spot opportunities while staying in the same tab. For newcomers learning what are keywords in seo, the extension provides immediate, contextual examples that reinforce understanding of keyword metrics and how they relate to search intent.

The tool is especially useful during early-stage research: generating ideas, checking volume for a long list of terms, and quickly triaging which terms warrant deeper analysis. This efficiency makes it a staple for many SEOs and content marketers who work across multiple niches.

Where it changes your decision

• When comparing keyword difficulty across similar terms — the extension's competition score gives a quick directional signal, but should be verified with a dedicated keyword difficulty tool before committing resources.
• When evaluating a new niche or topic — the related keyword and long-tail keyword suggestions help identify sub-topics and content angles that might otherwise be missed.
• When deciding whether to target a keyword for SEO or PPC — the combination of volume and CPC data helps distinguish high-intent commercial queries from informational ones.

Common mistakes

• Treating the extension's metrics as exact truth — they are estimates, and rankings depend on intent, content quality, links, and SERP features.
• Using the extension alone and skipping manual SERP review, search intent analysis, and competitor assessment — this can lead to targeting terms that look good on paper but lack real opportunity.
• Assuming every platform or region is supported equally — coverage varies by site, browser, and feature set, so verify before relying on data for a specific vertical.
• Ignoring credit usage or plan limits — users can unexpectedly hit a paywall mid-research if they do not monitor their remaining credits.
