I’m a visual thinker; I love looking at images. If I think about my search behavior, I catch myself looking at images quite often, for instance when I want to know what city X looks like. Or if I’m looking for a product I’ve seen somewhere, without knowing the brand or where I can buy it. You can imagine that there are a couple of cases when an image says more than a thousand words (I know, cliché) and that image search can be more useful than an overall search. The question is: how can I find out if I get traffic from image search? Let’s find out!
