For more than a year now most
SEO experts have discounted the importance of
PR in SERPs but it still plays an important part in
SEO, and certainly isn't a game to Google. Here are several good reasons to take
PR seriously:
1. Almost all link activity still uses
PR as a key measure of whether the source page of the link is worthwhile
2. It is a fairly accurate measure of the strength of a site, (ie a site with PR2 clearly has few ibls and is probably largely ignored by Google compare to a PR5 site)
3. There is still a thiving business in selling links on high
PR pages, with lots of money being thrown at this
4. The Jagger update clearly demonstrated a return to weight of the index page
PR, therefore a single page on a tourist destination from a huge travel site with a PR7 seems to rank better than a newer site with 200 pages on that same destination but an index page
PR of 5.
5.
PR is a quick and easy reference for whether a page (which your link is on) is being spidered
6. There is a correllation between the effetiveness of an ibl and the
PR of the source page of the site/relevancy/number of ibls (meaning I would rather have 1 link on a relevant PR3 page with only 5 other ibls than 10 links on PR2 pages each with 20 links on).
7. The higher the
PR the more difficult it is to 'buy in' for example to get a PR7 you would need to buy a link from a PR8 page which would cost a fortune, therefore a site with PR7 either has lots of money (and must mean business) or has succeeded in getting lots and lots of PR6 & 5 links.
