So Lets say I have a sitewide link on a site with many PR4-1 inner pages. Is the pagerank from each of those pages passed onto my site? Or does only the highest pagerank page count... thanks!
I believe only PR3+ pages can pass on PR. All of the PR3+ links on the site should pass on PR though. It won't necessarily help your rankings a lot as Google doesn't like sitewide links.
Well. It's complicated (at least I think)... Agree with above, site-wide links are not all that great. However, when mixed in with other links, that's fine. As for what rank you will actually get juice from, each page essentially has it's own power. However, the overall power of the site is also a factor in the juice calculation. I learned this from the survey done at SEOMoz....
If olny page rank 3+ sites pass page rank how does a site get page rank? How does a page rank 3 become a page rank three - that makes no sense. Each page has its own page rank and can pass the page rank to any page you link to. Even if the page rank bad shows 0/10 page rank the page will still have some page rank and will pass page rank.
"When a man asked if site wide links still work I immediately said “yes, they do but not always for the long term…We’ve found they work best when competing with fewer links and when hosted on pages that are several years old.†In the early days of search, link popularity was all about the numbers. If you had lots of inbound links and some keywords on the page, you ranked well. After time, the engines put more emphasis on query indicators and weighted keyword anchors. At the height of anchor text popularity you could “bomb†your way to the top fairly easily, even in the competitive markets. In today’s linking landscape, where you place links seems to have as much impact as the keyword anchors they use. That makes it doubly important to find older quality pages within your niche to host links such as site wides. While they are easy to use, site wides have been known to lose their ability to pass link popularity if hosted among large numbers of unrelated links or on crappy pages. Why? Because site wides are associated with paid links. Perception is key these days so any webpage hosting what appears to be paid links (even if they’re not) will probably be devalued. If you plan to use site wides, look to place them on better, aged webpages and vary your anchor text phrases." http://searchengineland.com/when-you-turn-a-link-on-does-it-return-the-favor-15160.php
