If you are searching for free stuff, let’s say, free images, web templates or hosting services using Google, word “free” in any standard search query immediately attracts spam. Best bet is to search your favorite social media sites. Social media sites have an active community of users who have already ranked and reviewed the specific free items that interest you. All you have to do is direct Google to search through each of these individual social media sites. Here are some examples how to specify your search:
site:digg.com free “web templates”
site:stumbleupon.com free images
site:del.icio.us free “web hosting”
