Matt Cutts said unit manager of WebSpam in Google in last night, in an interview a controversial, it was considered a big surprise for many experts the Search Engine Optimization, Google started to change its policy toward labeling NOFOLLOW.
To clarify the meaning of the change I will explain the post-labeling as it was before and how it has now become a simple quote from the explanation of the process:
* In the past, marking NOFOLLOW means that the distribution of Google PR of the links that carry the tag, so suppose you have a site and a Google PR equal to 10, and out of the 10 links, 5 with the tag NOFOLLOW and 5 without him, was simply the 5 links that do not bear the marking will two vote (for a total of 5 * 2 = 10), while the other five will not get any vote.
* Now, after the change and the same previous example, the tags will be lost five Tsoitatk 5 of the 10, but you get the links without marking NOFOLLOW to one vote out of 5 for a total of total (5 * 1 = 5). In other words, half the amount of votes appreciates your done have gone with the wind! , Ie, that marking NOFOLLOW is still effective in preventing the links that afford to get a vote for Page Rank, but will not provide the rest of the Tsoitatk for distribution on the links that are not labeled NOFOLLOW.
I believe, and as an analytical Profile that Google team noted excessive site managers in the use of this tag which may have an impact on the march, followed by Google or denied many of the important pages are getting the Big Rank or be crawling with more regularly.
And many of the site managers have taken using the method of carving Google PR (Page Rank Sculpting) through the use of labeling NOFOLLOW, any distribution beige Rank internally on the pages of their sites, including generating more income for them (to give the pages with higher profitability Page Rank greater). Perhaps this is the way engineers do not like Google, or they might believe that the most important thing for them is to crawl more pages and archiving.
I think it’s time to think effectively use branding NOFOLLOW especially for the owners of forums and blogs. Where they are used this tag significantly.
