Gianluca Fiorelli, an influential SEO agency veteran observer, says that Google Ranking Factor lists are DANGEROUS. http://moz.com/blog/the-myth-of-googles-200-ranking-factors Do you agree with this? For me, any sort of balanced guidance is better than taking shots in the dark. Plus, the Brian Dean post he referenced actually offered evidentiary SUPPORT for each of the list items he mentioned. Anyway, Fiorelli goes for the jugular of many of the factors discussed on this forum. What do you guys think?
