Keywords Everywhere
I keep the Keywords Everywhere extension installed on all my browsers, but I've learned to treat its volume numbers as directional hints rather than facts.
The short verdict
- Install the extension on Chrome or Firefox for instant volume and CPC data while you scan a SERP, then cross-check with Google Keyword Planner before committing budget.
- Use the related keywords pop-up to generate long-tail variations when you are stuck for ideas during content planning.
- Set aside a small credit budget if you research keywords more than a few times a week; the free tier runs out quickly and buying the smallest pack is cheap.
- Never rely on the volume numbers alone for niche or local queries because the estimations vary significantly from planner data.
What it's good at
The main reason I still use Keywords Everywhere is speed. I can search "best coffee grinder" on Google and see monthly volume (22k), CPC ($2.50) and competition level (low) right next to each organic result. That tells me in under a second whether the query is worth my time. No tab switching, no pasting URLs into another tool.
It also works on YouTube and Amazon. When I was planning a video about "how to clean espresso machine", the extension showed YouTube search volume for that phrase alongside related video keywords like "espresso machine descaling frequency". That saved me from guessing which angle people actually search for.
The related keywords feature is where I get the most leverage. One search for "SEO tools" returns a sidebar of long-tail variants: "SEO tools for small business", "SEO tools list 2025", "free SEO tools for beginners". I pull those into a spreadsheet in about two minutes. That would take me ten times longer if I had to run separate queries in a keyword planner.
I used to think the volume numbers were gospel until I cross-checked with Search Console and saw a 40% gap on a high-traffic page. Now I treat them as directional signals. They are good enough to prioritise which keywords to research further, but not precise enough to forecast traffic.
The freemium model works for me: you get a handful of free credits to test the tool, then you buy credits in bundles. My first $10 pack lasted about three months of weekly keyword hunts. I wish the credit consumption was more transparent, but the pricing is fair for casual use.
What it's awkward for
The biggest awkwardness is the volume estimates. I once compared a niche query, "sourdough starter troubleshooting", across two tools: Keywords Everywhere showed 300 monthly searches, Google Keyword Planner showed 600. That is a 50% discrepancy. Neither is the real number, but if I had used the extension alone to decide whether to write the article, I might have skipped a perfectly good opportunity.
The tool does not provide keyword difficulty scores. When I am deciding between "on page SEO" (volume 2k) and "on-page SEO checklist" (volume 800), I need to know which one is easier to rank for. Without difficulty data, I either guess or open another tool. That breaks the workflow advantage the extension promises.
CPC and competition columns are from third-party models. I changed my mind about relying on those for PPC campaigns after a client's actual cost-per-click was double the extension's estimate. The data is fine for a directional sanity check, but do not let it inform your bid strategy.
Another practical annoyance: the hover pop-ups sometimes block the search results you are trying to read. On a cluttered SERP with featured snippets and ads, the overlay gets in the way. You can adjust the pop-up delay in settings, but I still find myself accidentally triggering data for irrelevant queries.
The credit system is opaque. You spend one credit per keyword look-up, but certain actions consume credits faster than you expect. I have burned through credits on tests I did not mean to run. A simpler subscription model would feel less fiddly.
Alternatives I'd consider
If you want a similar browser extension but with keyword difficulty baked in, try [Ubersuggest](/ubersuggest/). Its free tier is more restrictive than Keywords Everywhere's, but the paid plans include competitive analysis and content ideas. I switched to Ubersuggest for a month but came back because Keywords Everywhere does a better job on YouTube volume data.
For full keyword research with reliable metrics, [Semrush](/semrush/) or [Ahrefs](/ahrefs/) are the obvious picks. They cost more, but they give you accurate volume, difficulty, SERP features, and historical trends. I use Semrush when I need to present numbers to a client. The extension is faster but less defensible.
[Google Trends](/google-trends/) is still the best free tool for comparing seasonality or rising queries. I use it alongside the extension to check that a keyword's volume is not just a temporary spike. It complements Keywords Everywhere well.
A lighter alternative is the [Keyword Checker](/keyword-checker/) – a simpler extension that focuses on volume and CPC without the related keywords clutter. It is less effective for idea generation but better if you just want a quick number without distractions.
If you need a broader suite of SEO tools beyond keyword research, browse the [SEO Tools](/seo-tools/) directory on this site. Keywords Everywhere fits neatly into a setup that includes a rank tracker and a site auditor.

Quick answers
How accurate are the monthly search volumes in Keywords Everywhere?
The volumes are estimations from third-party data, not Google's internal clickstream. I routinely see gaps of 40-50% compared to Google Keyword Planner. Use them to prioritise which queries to research next, but do not base budget decisions on them without a second source.
Does Keywords Everywhere work on YouTube and Amazon?
Yes. The extension surfaces volume, CPC and competition data on Google, YouTube, Amazon, and several other platforms. I find the YouTube data especially useful for video content planning because few free tools provide YouTube search volume.
Is Keywords Everywhere free to use?
It has a freemium model. You get a small number of free credits to test the tool. After those run out, you buy credit bundles or a subscription. The smallest credit pack costs about $10 and covers around 100,000 look-ups, which lasts the average practitioner a few months.
How do I install and set up Keywords Everywhere?
Install the extension from the Chrome Web Store or Firefox Add-ons site. Create a free account on the Keywords Everywhere website to get an API key. Paste that key into the extension's settings page, and you are ready to see keyword data appear on your SERPs.
