As I crawl around the Web 2.0 world, I’m seeing more examples of “parked” spam pages on social networking sites. They’re easy to find in Technorati, and I’ve also just spotted some on Squiddo. Why didn’t the creators of these sites just get a domain and park it? Well, for one thing, a lot of Web 2.0 sites are giving away sub-domains and their pages are already being indexed. Plus, these sites make it easy for their pages to be linked together, possibly giving a site a ranking advantage.
Most of the spam sites don’t add widgets to their pages, text is good enough, I suppose. Also, the social-sites are using cool URIs which makes them more accessible and appreciated by indexing spiders.
