SEO Next are a joke of a company they use a Indian company to write articles but the articles are not relevant to the links that are then placed in the article. They also post links in comments on sites talking about irrelevant things for example: site talking about cooking when the link is for motor spares which is in the comments and not the article itself. None of the sites they link to have any relevance to the site they are trying to promote. All links go to your home page in my case there were 7500 links to my home page here is a few of the links

IF you do not believe what i am saying have a look at there case studies and put them into Alexa just follow a couple of there back links to the articles and you will find the links posted in the comments for example

case study of theunderfloorheatingstore the link 95 is to peterleehc an article about credit cards yet the link for this site is in the comments. it is the second from last comment. you can do this with all there case studies and follow the links these are the sort of links that get you kicked off google.

do not go near these guys with a barge pole
