Each and every day i get called up from an SEO company who promises to get me top spots in Google rankings if i quickly get on their special offer they have today normally i would say "no thanks and put the phone down" but i had a bit of spare time so i indulged the guy and we got talking.
After the introductions and speal about his company he was showing me what his company does and how they go about it to get me top ranks (they don't get me ranks but create a website they own which then passes leads to me- kinda clever since they could then start charging me per lead or my competitors)
We continued to talk and i mentioned i used SEOmoz to check my rankings and back links etc and he told me that Google are cracking down and anyone using these types of software/websites will get their websites de indexed.
This struck me as BS but i wanted to get your thoughts on the matter, i personally don't believe Google would ever do such a thing as this since it would be so easy to get your competitors websites taken down (i.e. negative seo) but its certainly a talking point.
