Hi My site has page rank 3 and if i exchange link with page rank4 , What rank my site will get ? how long it takes for the new page rank to get displayed.
It depends on how many other links there are on the linking page, but it would be impossible to say even if we knew. However long it is to the next public toolbar update. They happen every few months.
Really no one can perdict these things... stop worrying about PR and just make you site awesome and you will naturally see your PR increase
I don't understand the formula for page rank its really quite tedious, but if some explained it a little better i'd probably make a page rank calculator
Roughly speaking, The PR passed to a page = The PR of the pages linking to it / the number of other outgoing links from that page * dampening factor (unknown but said to be around 0.85) Experience (and the above formula) tells me you'll have to do a lot more than exchange links with more than one PR4 to push a PR3 page up. Even a PR5 link probably won't do it unless you're already close.
PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page.
Focus on gathering quality related backlinks because that will lead you to a good result in ranking and a high PR.
I don't think a high PR link will necessarily boost your site. Google has some mechanism in place that stops people from selling high PR links to other sites. So I suspect that they weed out these links by checking whether the sites are relevant to each other (perhaps based on whether they share words that aren't commonly used). Google also probably discounts the value of reciprocal links as that has been abused in the past. re: The page rank table I don't think it's true as I have a PR2 webpage with 4/5 PR0 follow links. (Webmaster tools shows 4 links, but it weeds out duplicate/similar content. I believe there are 5 PR0 follow links out there.) http://www.glennchan.info/articles/technical/chromata/chromata.ht ml <--remove those spaces. I don't want this post's link to disturb the current PR. 3 of those links are from foreign language pages. (For some reason, I see these foreign language sites show up when you do related/similar searches on a site.) Your guess is as good as mine as to what's happening. My page is on a very obscure topic (chroma subsampling), but it does rank on searches like "Y'CbCr subsampling" and its title.
