I started to answer this question privately, but the thought came to me that quite a few people might want to know the answer outside the circle. Hence, a blog on:
“The purpose of this group is to syndicate blog comments and increase each other’s blog exposure. What do you think about the blog link exchange?
This is good for each other’s website SEO and I find no disadvantage except if the other will not link back to reciprocate. I know Jimmy here is the SEO expert, who specializes in amazon listing optimization services and anything related to websites, Google and eBay.
Any thoughts on this?”
