A good friend of mine just told me about a fairly new site called Qassia where you can add links to an unlimited number of sites. Qassia is well ranked and indexed in the search engines, so acts as a very good source of quality backlinks.
They also have an ad revenue sharing system, so any traffic your Qassia pages get could be earning a little extra cash for you as well. I don’t think it will be enough to make it worthwhile as an income stream, but for extra backlinks, it’s well worth the effort.
There’s not really that much extra to say about it, other than to check them out and sign up – it’s free and looks like it’s going to offer some valuable authority links to your sites. Check out Qassia here.
Once you’ve signed up, click on the link for “Dashboard” and there’ll you’ll find a link to the user manual titled “how to promote your websites on qassia“. This tells you exactly how to add your sites to your account.
If you have lots of sites, or a mixture of white hat and black hat sites, you want to consider opening seperate accounts for each.
