Lynn, it is so true that just talking about a brand in a blog post gets you noticed. I did a blog post a few years ago on a toy and mentioned that is was on the Parenting Magazine top 10 list. I did not link to the magazine, I just mentioned it and they sent me a free one year subscription to their magazine, and a whole box of coloring books for my kids. It wasn't monetary, but at least the company acknowledge that I referenced them.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
