Is pagerank finite?
Posted on February 15, 2007 - Filed Under Tips |
Is pagerank diluted as you add more content to your website?
Is pagerank diluted as Google adds more filetypes to the index?
Can issues with numerical accuracy result in “chaotic” pagerank
fluctuations?
The more questions one asks the more questions one has, all ideas are welcome.

All webpage’s pageranks add up to 1.

As pages get added to the Google index (and as all pages other than yours have more and more links pointing to them), your site’s and pages’ pagerank reduces, relatively.
So keeping building those links, or hope that the sites linking to you keep increasing their own pagerank :)

PageRank is such a trivial part of the Google algorithm anyway, when it comes to determining Web results rankings, people don’t need to worry about it. PageRank matters when it’s sufficient to boost page A above page B, where A is more relevant to a query than B. And the Toolbar certainly is no indicator of when that happens since many low TBPR sites outrank many high TBPR sites in millions of queries.
In the meantime, Aaron, I’d like to point out that I do give you link love on the SEO Theory blog because you’re in my blogroll. Deservedly so.
And speaking of Google, I did just post an article titled “Google Broken: Supplemental Pages Not Being Parsed And Indexed” (ladies and gentlemen, I give TITLE DROPPING SPAM).

“And the Toolbar certainly is no indicator of when that happens since many low TBPR sites outrank many high TBPR sites in millions of queries.”
Same goes with domain “age”,”trust”,”authority” etc where people claim authority sites will rank above new sites. If there’s no one linking to the authority site with the targeted keywords in the anchor text, then a new page on a new site can outrank it. It does not matter how many IBLs point at a site. If you got more link juice to a particular PAGE with the right anchor text, you can trump “authority”, “trust” and domain “age” any day of the week. And it doesn’t matter how high a page’s TBPR is either, if the IBLs to that page are unrelated to the keywords you’re going after and if your page never mentions the keyword at all.

Google Broken: Supplemental Pages Not Being Parsed And Indexed

I don’t think so. I believe as you add more content to your site and it grows in size, Google scales your weight a bit, however with internal linking, all additional pages you add (such as posts), usually have a link back to the homepage or category pages as well. This means if a tiny amount of PR leaks to a new post, that new post will gain a small amount of weight, and in turn add another linkback to your homepage. I think doing this on a large scale is how sites like Digg or About.com became the massive beasts they are today.
Now don’t misunderstand me, I’m referring strictly to internal linking. If on every post you have 50 external links to unrelated sites, you’d probably be leaking your PR to them, and getting nothing in return, causing your blog’s overall weight to decrease.
Just my $0.02 however.

You cannot leak PR. If we assume for the sake of discussion that Google is assigning PageRank only to 5,000,000,000 pages then the typical site only gets a minute amount of PageRank anyway — and that is adjusted on the basis of who links in (or who stops linking in) not on where you link out to.
