KeyLens
Last updated 10 October 2026
KeyLens looks up search volumes for the keywords on the search pages you visit.
Stays in your browser
Keywords are read from Google, YouTube and Amazon search pages in your browser. Starred lists and history stay local.
Amazon keyword ideas come straight from Amazon’s own autocomplete.
Sent to our server
The keywords to look up and the country. Metrics are cached for 30 days and shared across all users; the cache does not record who asked.
Daily lookup counts (free plan) and your credit balance and spending history (paid plans).
Like every extension we make: your install id, your licence if you have one, usage counts for plan limits, and optional “Help improve” data if you turn it on. See the main privacy policy.
Other services
DataForSEO: Keyword volume, CPC, competition and trend data (keywords and country only).
Your choices
Uninstalling removes everything the extension stored in your browser. To have the data on our server deleted, email us.
