A few people have been asking how to check their image search stats and which keywords were used, after they’ve applied my Google Analytics image search “hack” or when they’re using the Google Analytics WordPress plugin. So, instead of typing this in each email, here’s a small howto.

And press go. You should then get something like this:

Clicking on each engine will give you the overview of keywords used in that engine. You could create a new filter for your site to be able to see all the image seach keywords in one overview under keywords.
