I have a Wordpress.org blog that has recently started getting a lot of comments posted to 5-6 articles. That seemed good at first, but now I have concerns. For the past 5 days, I have been getting 8-10 comments each day posted to these articles. The problem is, many of these comments are written almost exactly alike - a few words are different, but that's it. Many of the back-linking URL's go to forums and websites not related to my niche. I have not seen the same the same back-linking URL more than once and the name on all of the comment posts are different. My concerns are: 1. Does anybody have any idea why this might be happening? I would like to think my articles and my site are that good, but when so many of the remarks are so similar, that concerns me. 2. Do the Google Bots use comments in their ranking factors? If two or more of these comments are similar, will Google penalize my site? 3. Will Google penalize my site if these back-linking URL's are to sites not related to my niche? I do get to review and approve/disapprove any comments posted to this site before they get posted and I have temporarily held up on approving any of them. Your input and thoughts would be appreciated.
