Even though our last post is more or less about the same topic, we decided to share an interesting question and feedback that we just received from our friend and “SEO Guru” Mike, who runs the company Webpage Design Kentucky. When I sent him the latest version of, he replied as follows:

“Very interesting concept. As I can see in internet marketing, there is a lot of review spamming going on. In a way, I think it is due to the new social indicators for SEO, as well as for the competitive edge the spammers think they are receiving. Do you think, with review spammers sending out negative reviews against competitors, that this causes a negative effect in the SERPs of search engines like Google for SEO?”

My answer:

“To my knowledge, there is no known algorithm that counts negative reviews into SERP yet, but I`m not 100% sure as it is changing fast. However, what I do know is that negative reviews are killing sales conversion rates. And, conversion rate has a direct impact on bounce rate, and bounce rate has a direct impact on SERP, as we know. So, then we can say that negative reviews have an impact on SERP.

On the other hand, positive reviews are delivering higher sales conversion rates on the web and on each advertising channel, SEO, SMO, PPC, etc. Also, the review can count as new valuable content.

Clients always pay more attention to businesses with genuine positive reputations and it again is about lowering bounce rates and increasing SERP rankings.”

Although I’ve given this reply, it appears to be only partial as I’m still wondering about something. Is there any other algorithm being used on the major search engines, not just the one via bounce rate that I mentioned above? Is there another algorithm that is counting negative and positive reviews, and affecting SERPs accordingly? Feedback Search Engine is Investigating SERPs for Businesses
