| Core function | Keywords Everywhere is a browser extension (Chrome and Firefox) that overlays keyword research data directly in the browser while you're using Google Search, Google Search Console, YouTube, Amazon, eBay, and other platforms. When you search on Google, it shows the search volume, cost-per-click (CPC), and competition score for the searched query and for related searches in the right-side panel. It also shows keyword data on competitor pages you visit (via the "On page" panel), in Google Analytics, and in Google Search Console. Keywords Everywhere operates on a credit-based pricing model — you purchase credits, and each keyword metric lookup costs one credit. It was previously free and moved to a paid credit model in 2019. | A crawl-based technical SEO and AI visibility auditor. Submits a URL, crawls the public HTTP output of the website, validates structured data against Google's Rich Results specifications, measures Core Web Vitals from real Chrome User Experience Report (CrUX) field data, detects broken links and canonical issues, checks robots.txt and sitemap configuration, and scores GEO (Generative Engine Optimisation) signals. Not a browser extension — a standalone web-based audit tool. |
| Keyword research data | Keywords Everywhere provides: search volume (monthly Google search volume for the queried keyword), CPC (cost-per-click from Google Ads — a proxy for commercial keyword value), competition score (Google Ads competition density — how many advertisers bid on the keyword), trend data (12-month search volume trend chart), and related keywords (keywords that commonly co-occur with the searched term). The data appears contextually as you browse — on Google SERPs, in GSC, and on competitor pages. This passive-browsing approach to keyword research is highly efficient: you discover keyword data while doing research you were already doing, without needing to open a separate keyword tool. Volume estimates are sourced from Google Keyword Planner data. | Doesn't provide keyword search volume, CPC, or competition data — the audit focuses on the technical and on-page signals that influence what a page ranks for, not keyword discovery. For keyword research, Keywords Everywhere, Ahrefs, Semrush, and Google Keyword Planner are the appropriate tools. The audit does check whether pages are structured to capture search demand effectively (meta title alignment with target query, content depth, heading structure, and structured data for query-specific Rich Results). |
| On-page SEO analysis | Keywords Everywhere's "On page" panel shows keyword density, related keywords used on the page, and entity mentions for any page you visit. This provides a quick view of which keywords a page appears to be optimised for and which related terms are present. However, it doesn't check structured data validity, canonical tags, broken links, render-blocking JavaScript, or any of the technical SEO signals that determine how Google evaluates the page beyond keyword presence. | Full on-page SEO audit covering: title tag (presence, length 55–65 characters, keyword alignment), meta description (presence, length 120–160 characters, uniqueness across pages), H1 heading (presence, uniqueness per page), heading hierarchy (H2–H6 structure for topical depth and passage ranking support), content depth (word count per page type), internal link depth and orphan page detection, canonical tag correctness, and AI visibility (question-heading ratio, content section chunkability). Platform-specific guidance (WordPress, Shopify, Next.js, etc.) explains the fix path for each issue. |
| Technical SEO audit | Keywords Everywhere is a keyword research and content intelligence browser extension — it does not perform technical SEO auditing. It doesn't crawl websites, check status codes, validate structured data, detect JavaScript rendering gaps, analyse sitemap coverage, check Core Web Vitals, or evaluate canonical tag correctness. For technical auditing, Keywords Everywhere users typically combine it with a separate technical audit tool (Screaming Frog, Ahrefs Site Audit, or DeepSEOAnalysis). | Full technical SEO audit: JSON-LD validation for all schema types against Google's Rich Results requirements with property-level error reporting; real CrUX Core Web Vitals (LCP, INP, CLS from actual Chrome users on mobile and desktop); broken link and orphan page detection; canonical tag correctness across all crawled pages; robots.txt and sitemap analysis; JavaScript rendering gap check comparing server HTML against rendered DOM; meta tag coverage; and AI visibility scoring. Free with no signup. |
| Competitor page analysis | Keywords Everywhere's "Competitor Gap" and "On Page" features let you see keyword data for competitor pages as you browse them — which keywords appear in their content, related terms they use, and estimated organic traffic estimates for the page. This is useful for quickly assessing what a competitor page covers and which keywords it targets, without leaving the browser tab. The "Competitor Traffic" metric shows estimated monthly organic visits for any page, giving a quick benchmark. | The audit analyses a single domain at a time — competitor page analysis requires running a separate audit for each competitor URL. The audit does check technical signals that matter competitively: whether the audited site's structured data, Core Web Vitals, AI visibility, and crawlability are competitive with what Google would expect to see on well-performing pages in the same category. For competitive keyword gap analysis, Keywords Everywhere's competitor features or full keyword tools (Ahrefs, Semrush) are more appropriate. |
| AI visibility | Keywords Everywhere focuses on traditional keyword research signals — search volume, CPC, competition — and doesn't assess AI visibility. It does show keyword data for queries that trigger AI Overviews (Google's AI-generated summaries that appear above organic results), but it doesn't evaluate whether a specific page is likely to be cited by AI systems. As AI Overviews shift click distribution away from traditional organic results for informational queries, assessing AI citation eligibility becomes an important gap in keyword-only research tools. | Full GEO score across all five AI visibility signals: AI crawler access in robots.txt, llms.txt presence at the domain root, FAQPage/HowTo JSON-LD in server-rendered HTML, question-heading ratio (≥20%), and content chunkability (avg section ≤400 words). Each signal includes platform-specific guidance — making it actionable for improving AI Overview citation eligibility alongside traditional organic ranking. |
| Best fit | Keywords Everywhere is best for SEO professionals, content writers, and PPC analysts who want keyword data surfaced passively while they browse — discovering search volumes and related terms in-context without switching tools. It's cost-efficient for medium-volume keyword research and complements full-suite tools (Ahrefs, Semrush) for casual browsing-based discovery. The credit model makes it affordable for occasional keyword lookup without a monthly subscription. | Best for sites that need a free, no-signup technical SEO and AI visibility audit — structured data validation, real CrUX Core Web Vitals, broken link and canonical issue detection, and a shareable audit URL — without purchasing keyword credits or a subscription. Most useful as the technical complement to Keywords Everywhere's keyword intelligence: KE tells you what queries are worth targeting; DeepSEOAnalysis tells you whether your pages are technically ready to rank for them. |

FAQ
Keywords Everywhere is a browser extension that shows keyword research data contextually as you browse. When you search on Google, it shows the monthly search volume, cost-per-click (CPC), and competition score for the query you searched, plus related keywords and their metrics in a right-side panel. On competitor pages you visit, it shows which keywords the page appears to target and estimated organic traffic. In Google Search Console, it shows additional keyword metrics alongside GSC data. In YouTube, it shows video keyword search volumes. The extension works by looking up keyword data (from its keyword database sourced from Google Keyword Planner) whenever you visit a supported platform, overlaying the data without you having to open a separate tool.
Keywords Everywhere uses a credit-based pricing model — you purchase a bundle of credits, and each keyword data lookup costs credits. Pricing tiers start at $10 for 100,000 credits, scaling to $80 for 1,000,000 credits and higher. Credits are consumed when you look up keyword data (each keyword metric shown costs 1 credit). The extension was free until 2019 when it switched to the credit model. Credits don't expire, so infrequent users can buy a small bundle and use it for months. Heavy users doing bulk keyword research will go through credits faster. For comparison, full SEO suite subscriptions (Semrush, Ahrefs) cost $100–$200+/month but include unlimited keyword lookups alongside other features.
Keywords Everywhere sources its search volume data from Google Keyword Planner, which provides volume ranges rather than exact counts. The extension shows a monthly search volume figure, but all keyword volume tools (including Ahrefs and Semrush) are modelled estimates — they approximate real search volume from available signals, not direct access to Google query data. Keywords Everywhere's volume accuracy is generally comparable to other tools that use GKP data. Accuracy is typically higher for high-volume keywords (where the GKP data has more signal) and lower for long-tail, low-volume keywords (where GKP may show 0–10 even if actual volume is 50–200). Use volume data for relative comparison (is this keyword roughly twice as searched as that one?) rather than as exact counts.
Yes, for a complete SEO workflow. Keywords Everywhere shows you what queries are worth targeting — search volume, commercial intent (via CPC), and which terms appear on competitor pages. A technical SEO audit shows you whether your pages are ready to rank for those queries — correct structured data, fast Core Web Vitals, canonical tags, internal linking, and AI visibility. Keywords Everywhere tells you the keyword strategy; a technical audit tells you whether the execution is sound. Using both in combination: use Keywords Everywhere to identify keyword opportunities, then use DeepSEOAnalysis to audit whether the pages targeting those keywords have the technical foundations Google needs to rank them competitively.
