nofollow to be used in links less important as, of commentaries in blogs, links external not trustworthy, politics of privacy, contact, images, page of login and etc. Of this form it would result in one better distribution of PageRank since the Google not indexa links with these attributes. However, in the fair of Search Marketing in Seattle, Matt Cutts launched a bomb on the attribute in – follow According to it, the algorithm of the Google was modified, and to add to the attribute nofollow in links, the PageRank will not save to sobrar more for links that is follow. Using the example that was given in conference SMX Advanced, before this alteration, a page that had authority in the value of $10 to distribute for links, and if links in the page had 10, 5 with follow and 5 with nofollow, each one of the 5 links follow passed $2, and the 5 links nofollow did not pass value. With this alteration, the 5 links with nofollow saved simply disappear of the map. With this change the PageRank of a page will be divides for the total of links existing in it, however, only for links that does not possess the attribute rel= nofollow. As this notice is recent and is generating sufficient doubts, critical, optimum to make it is to wait to see what it really goes to happen. But, to prevent ackward surprises, and so that this alteration does not cause a great impact in its PageRank, it reduces the total number of links for page. Vincent BenedictoConsultor SEOGriff Art
