Hi SEO experts. how does this effect having many 0-4 with few pr 5 and one pr 8 link. will this help to get highier pr ?
I think it depends on the number of other links on each page. If the pr 8 has many out going links it is not as valuable as if it had very few.
Not all links are counted by Google. For instance, they filter out links from known link farms. Some links can cause a site to be penalized by Google. They rightly figure that webmasters cannot control which sites link to their sites, but they can control which sites they link out to. For this reason, links into a site cannot harm the site, but links from a site can be harmful if they link to penalized sites. So be careful which sites you link to. If a site has PR0, it is usually a penalty, and it would be unwise to link to it. How is PageRank calculated? To calculate the PageRank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site. PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn)) That's the equation that calculates a page's PageRank. It's the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren't telling us what it is. It doesn't matter though, as this equation is good enough. In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.
