Keywords Everywhere
Keywords Everywhere is a browser extension (Chrome, Firefox, Edge) that overlays search volume, CPC, competition, and 12-month trend data directly onto Google, YouTube, Amazon, and a dozen other sites, plus Moz-sourced domain and backlink metrics. It runs on a pay-as-you-go credit system rather than a monthly subscription.
Partially — the search volume numbers are literally Google Keyword Planner's own data and the domain/backlink metrics are Moz's, so the data itself isn't a moat, but correctly overlaying it onto a dozen different sites' search results (Google, YouTube, Amazon, eBay, Etsy, Bing, and more) as those pages change is real, ongoing engineering work.
What you lose building it yourself
- ✕One extension that already overlays data correctly across 10+ sites, kept working as those sites change
- ✕A running credit-billing system instead of building and maintaining your own
- ✕Moz's domain/backlink metrics shown alongside keyword data in the same view
Why people still pay
Keywords Everywhere already maintains working overlays across a dozen sites whose page layouts change without notice, plus billing — a DIY version covering just Google search still leaves 10+ other integrations and a metering system to build and keep working.
BUILD YOUR OWN · THE EXTENSION, NOT THE DATA
The data itself needs no building — a free Google Ads account gets you the same Keyword Planner search volume numbers directly, and Moz's own dashboard shows the same domain and backlink metrics. What you'd actually be rebuilding is the convenience layer: a browser extension that shows that data on top of Google, YouTube, and Amazon results pages as you browse, plus a credit-metering system to bill for it.
StackA browser extension for Google, YouTube, and Amazon search pages · Google Keyword Planner access via a Google Ads account.
Build a Chrome browser extension that runs on google.com/search pages. When the page loads, read the search query from the page, call the Google Keyword Planner API (via a Google Ads developer account) for that query's monthly search volume and CPC, and show a small badge with both numbers next to the search box. Cache each lookup in the extension's local storage for 24 hours so repeat searches for the same query don't call the API again.

Free alternative: Google Keyword Planner — gives you the exact same search volume and CPC numbers Keywords Everywhere displays, directly and for free with a Google Ads account, but without the in-page overlay convenience, the Moz-sourced domain/backlink metrics, or the multi-site (YouTube/Amazon/etc.) coverage
Vendor's own claim
"Keywords Everywhere uses the same search volume data that Google Keyword Planner provides, so the numbers come from Google itself."

QUESTIONS
Is Keywords Everywhere free to install?
Yes — the browser extension itself is free for Chrome, Firefox, and Edge. Search volume, CPC, and other data require purchasing credits, which start at $80 for 200,000 credits and expire one year after purchase.
How much does one search actually cost in credits?
One credit covers one keyword. But a single Google search can use far more than one: per Keywords Everywhere's own documentation, a search page showing 20 "People also search for" terms and 8 related keywords uses 29 credits total — 1 for the main query plus 1 for every keyword shown alongside it.
Where do the Domain Authority and Spam Score numbers come from?
They're Moz's own metrics, not something Keywords Everywhere calculates itself — its FAQ defines Domain Authority and Spam Score as Moz scoring systems, the same source Ubersuggest and Mangools license their backlink data from.
