I've been wondering. Do people really search a lot on google images? I mean, do they use it to search for content past the image itself?
I could imagine for example that someone would search for his friend in google image search in order to filter out the results better so that he doesn't have to click on every image in order to verify that it's really his friend.
On the other hand, I've rarely done that and I cannot think of many other usecases aside from just looking for the images itself and using them somewhere (legally or illegally, doesn't matter for now).
In my specific case, G is allowed to crawl all images on the site. And I've noticed (as described in another question) that my image search queries and subsequent impressions / clicks are much higher than from the web search (about double). This is especially surprising to me because my site sells electronic devices (which I would never look for via G images). The motivation of my post is the question whether I should just accept that as valid traffic or be really concerned that my web search queries aren't higher than the image search queries.
TL;DR: Are there statistics on how many search requests there are on
images.google.com vs the standard web search?
