If I build backlinks to websites hosted on same IP from same set of websites by Blog Commenting then how will it effect my Google, Yahoo and Bing rankings and the PR(Important) on Google.com ?
It depends on the interlinking. If you link all the websites to each other, as well as having in bound links, then there is a change Google will peg you as a link farm.
I think the quality counts, spam i would figure would hurt and the same IP would prob count as one.. not positive though!
hi Jarwi, i wouldn't do it because be google takes IP address into consideration in their algorithm. they expect to see the back-links from different IP address even better if the websites are on class C IP address.
