Hi, My blog gets decent traffic from google image search. But to learn or to go deep into this traffic source, I need to know the image search keywords driving traffic to my blog. How to do this? Is there any tool available? Please Help.
Your best source for this is Google WebMaster Tools. You can also find it in Google Analytics, but rather oddly, it gets listed as a referrer, rather than as a search engine - but it'll all be in there, once it's installed and tracking.
