By submitting your pictures to social media sites you create one-way backlinks and more another way for people to find your site. Take advantage of this qualified traffic  by giving your picture a good title and add tags that make it easy to find.

If you have determined that the behavior of your customers is driven my images then Flickr is the most well known and highest trafficked tool. However Flickr is not a bookmarking site but consider the option to vote pictures up or down a part of a typical bookmarking site. There are others, though, that do have that feature included like vi.sualize.us, with a page rank of 5 ripe for one waylinks back!

Once you submit your picture, others can vote your picture up with the “like it” button. The more people that cast their vote the more traffic you are likely to get to your site.

Picfor.me  is another typical bookmarking site, with a “pick me” button to make the picture more popular. A great feature at Picfor.me  is to you add a bookmark button to your toolbar browser making it very easy to bookmark pictures. Once a picture is bookmarked, you will see that picfor.me logo in the top right hand corner of the picture.  There are many others, like  incredimazing (PR 4) and typeish (PR 4)  worth considering.

Picture book marking is an underutilized way for you to engange your customers with minimal competition.

Put your content to work and increase the visibility of site and the traffic that results from it.
