Example: Name: "Red T-Shirts" URL (optional): "http://red-tshirt-site.com/"
Then they'll perform better for that keyword (maybe--google eventually penalizes this).
- Text that does not clearly market anything or provide a meaningful backlink may be part of a larger link network, or just simply testing to generate a list of vulnerable blogs. Those lists can be sold to others or used for your own purposes.
- Similar to some recent spam bots hitting Google Analytics referrer results, these people may not care about organic rankings. They might be marketing to the blog owner who sees the comment and investigates the username/link. If I'm spamming for SEO services, and you are a blog owner looking to increase traffic for example, the attempt may not be about ranking for SEO terms (a losing battle), but simply getting you to look at my site.
Basically they would spam these out to not look overly spammy, and have their website and name listed as their website they are trying to promote as people use to believe that having millions of shitty backlinks is good SEO.
What Google should do is make the links have no effect at all, thus preventing this abuse.
(Although Google denies it's a problem.)
Thank you for allowing me to talk myself into a circle. :-)
