A new addition to my useful tools set is “Keywords Everywhere”. This neat Chrome and Firefox browser extension will instantly show you the search volume and AdWords cost for a particular search, right by the search itself. Something like this:
If you’re testing out some quick ideas, and want the official Google data, it can be a real time-saver. In addition, Keywords Everywhere adds columns for search volume, AdWords CPC and ‘competition’ to the Search Analytics report in Search Console, and the equivalent report in Google Analytics, which is really rather wonderful. Finally, you can also upload lists of search terms and get the data back instantly. Give it a try – it’s free.
UPDATE June 2020: It doesn’t appear to be free any longer. The developers of WMS Everywhere suggest that their product would be a suitable free alternative.
