Keywords Everywhere Review: Is It Enough for Gap Analysis?
You install the Chrome extension, load up a search results page, and suddenly every keyword has a number next to it. Volume, CPC, trend sparklines — it's satisfying in a way that feels productive. You start clicking around, bookmarking keywords, exporting CSVs.
Then three months later, you check your rankings and nothing has meaningfully moved. You have a spreadsheet full of keywords but no real picture of why competitors are outranking you or what content you're actually missing.
That's the gap between what Keywords Everywhere does well and what gap analysis actually requires.
What Keywords Everywhere Actually Does
Keywords Everywhere is a browser extension (Chrome and Firefox) that overlays keyword data directly onto search results pages, Google Search Console, YouTube, Amazon, and a handful of other platforms. You pay for credits — each keyword lookup costs one credit — and the data appears inline as you browse.
What you get per keyword:
- Monthly search volume (US and other countries)
- CPC (what advertisers pay per click)
- Competition score (advertiser competition, not SEO difficulty)
- Trend data (12-month sparkline)
- Related keywords and "People Also Search For" panels
For quick, in-context volume checks, it's genuinely useful. If you're writing a blog post and want to know whether "project management for freelancers" or "freelance project tracking" gets more searches, Keywords Everywhere answers that in seconds without opening another tab.
Understanding what search volume actually means for prioritization matters here — volume alone doesn't tell you whether a keyword is worth targeting.
Where It Falls Short for Gap Analysis
Gap analysis — figuring out which keywords your competitors rank for that you don't — requires a fundamentally different kind of data collection. It's not about enriching your browsing; it's about systematically crawling competitor domains and comparing their keyword footprint against yours.
Keywords Everywhere doesn't do this.
Here's what's missing:
No domain-level keyword data. You can't type in a competitor's URL and see which keywords are driving their traffic. You only see data for the searches you manually run.
No competitive comparison. There's no feature that says "Competitor A ranks for 400 keywords you don't." That requires indexed data at scale — something the extension architecture can't provide.
No content gap report. Gap analysis tools pull data from their own crawl indexes. Keywords Everywhere pulls data from Google's autocomplete and search results as you browse. The methodology is completely different.
Competition score is advertiser competition, not SEO difficulty. A keyword showing "0.8 competition" in Keywords Everywhere means advertisers are bidding heavily — not that it's hard to rank organically. These are often conflated, and it leads to targeting decisions that don't reflect actual ranking difficulty.
You're limited to what you think to search for. This is the fundamental constraint. Gap analysis should surface opportunities you wouldn't have thought to look for. If you already know what to search, you're not finding gaps — you're confirming assumptions.
What Keywords Everywhere Is Actually Good For
None of the above means Keywords Everywhere is a bad tool. It's cheap ($10 gets you 100,000 credits, which lasts most users a long time), lightweight, and fits naturally into a research workflow.
Where it earns its place:
- Validating ideas quickly. Before you write something, a fast volume check tells you whether anyone is searching for it.
- Comparing variations. Which phrasing gets more searches? The inline data makes this fast.
- YouTube and Amazon keyword research. The extension works on those platforms, which many dedicated SEO tools don't cover.
- On-the-fly enrichment. When you're reading a competitor's page and want to know the volume of terms they're using, it's right there.
If you're doing light keyword research as part of writing — not as a dedicated SEO workflow — Keywords Everywhere fits that use case well.
What Gap Analysis Actually Requires
If you're serious about finding content you should be building, you need tools with large keyword indexes that can compare domains. The major options:
Ahrefs — The content gap report under "Competing Domains" is one of the better implementations. You enter your domain and up to five competitors, and it shows keywords they rank for that you don't. Starts around $99/month.
Semrush — Has a Keyword Gap tool that works similarly. Also shows where you're ranking lower than competitors for the same keyword. Similar pricing.
Moz Pro — Has competitive analysis features, though the index is smaller than Ahrefs or Semrush. Worth considering if you're already in the Moz ecosystem.
Ubersuggest — Cheaper entry point, more limited data. Fine for smaller sites where Ahrefs/Semrush pricing is hard to justify.
Manual approach — Enter competitor URLs into a free tool like Ubersuggest's limited free tier, or use Google Search Console to find your own ranking keywords, then manually check whether competitors rank for those too. Time-consuming but free.
Tracking what's actually ranking is a separate step from finding gaps — most of these tools combine both, which is part of what justifies the price.
If you've done gap analysis and found content opportunities but your new pages aren't gaining traction, there are often structural reasons — here's why organic keywords sometimes don't rank even when you're targeting the right terms.
The Honest Comparison
| What you need | Keywords Everywhere | Gap analysis tools |
|---|---|---|
| Volume for a keyword you name | ✓ | ✓ |
| Competitor domain analysis | ✗ | ✓ |
| Content gap report | ✗ | ✓ |
| Works while browsing | ✓ | ✗ |
| Affordable for casual use | ✓ | Varies |
| SEO difficulty (not ad competition) | ✗ | ✓ |
These tools serve different moments in a workflow. Keywords Everywhere answers "how much search volume does this keyword have?" Gap analysis tools answer "what keywords should I be targeting that I haven't considered yet?"
Using Keywords Everywhere for gap analysis is like using a tape measure to find out what rooms your house is missing. Wrong tool for that question.
One More Option Worth Knowing
If your site has existing domain authority but you're missing a large swath of content your competitors are capturing, the problem isn't just identifying the gaps — it's building the content at a scale that moves the needle. Rankfill is one option here: it maps competitor keyword footprints against your domain and pairs the gap report with content deployment, for sites that need both the analysis and the output.

FAQ
Is Keywords Everywhere worth paying for? Yes, for what it does. At $10 for 100,000 credits, it's inexpensive enough that the cost is rarely the issue. The question is whether it's the right tool for what you're trying to accomplish — and for gap analysis specifically, it isn't.
Does Keywords Everywhere show SEO difficulty? No. The "competition" score it shows is paid search (advertiser) competition, not organic ranking difficulty. For SEO difficulty, you need a tool with its own keyword index, like Ahrefs or Semrush.
Can I use Keywords Everywhere to find what competitors rank for? Not directly. You'd have to manually search for keywords you suspect competitors are targeting, then see their rankings in the SERP. There's no way to input a competitor URL and get their full keyword list.
What's the difference between Keywords Everywhere and Ahrefs? Keywords Everywhere is a browser extension that enriches your search sessions with volume data. Ahrefs is a standalone platform with a crawled index of billions of keywords, domain-level data, backlink analysis, and content gap reporting. They're different categories of tool.
How accurate is Keywords Everywhere's search volume data? It pulls from Google Keyword Planner data, the same source most tools use. Accuracy is reasonable for established keywords, less reliable for new or very low-volume terms. Search volume estimates always have some imprecision — use them for directional decisions, not precise forecasts.
Can I do gap analysis without paying for Ahrefs or Semrush? You can get a partial picture using free tiers of Ubersuggest or Moz, or by combining Google Search Console data (your own keywords) with manual checks. It's slower and less complete, but workable for small sites with limited budgets.
