I have a WP site that has been live for about 3 years now, gets about 300 clicks p/d but the majority of those clicks are coming from image traffic from irrelevant keywords that I'm not even trying to rank for. This site used to make a ton of money but then the niche hit some legal turbulence and now it's pretty much worthless. I've got an image ranking on the first page of google images for a keyword that gets 13.6m global searches a month. This single keyword is generating over 90% of my site's total traffic. The image isn't even mine... I think I took it from WebMD a couple years ago and just resized it. So why do images rank so well on WP blogs? Is there a way to make the actual page that the images are on rank higher than the images itself? Has anyone experimented with different types of on-page linking? like linking the images back to the page URL itself as a permalink?
