Example:
Site "A" has 56 links and PR of 3
has a 4 word title
has no outgoing links
has a total of 8 pages
Uses CSS and straight html
has been optimized using 3.5 to 4% keyword density
Not using any tricky stuff at all
Site "B" has 22 links and PR of 5
has a 22 word title! (Yikes)
has 6 outgoing links
has a total of 9 pages
Uses php and javascript
has not been optimized
Is not using any tricky stuff.
Having checked the links for both sites, site B (with a PR of 5) has nearly identical links to the ones as site A. Site A just has a few more relevant links ... but less PR?
Neither site is employing any cloaking, redirects, hidden text or any devious stuff.
I did a keyword count for both to compare densities, but site B is using php and javascript and comes up with absolute garbage in the keyword count. I don't know why.
Site A beats site B in the SERPS for all relevant searches. Site B had an Adwords campaign going a while back. I can only assume it wasn't paying off for him. He shows up nowhere in the SERPS that I have been able to find.
Now ... can somebody please explain what PR is all about? I am obviously missing an important aspect of PR cause it doesn't make any sense to me.
I guess you are talking about PR of the index page only.
Site B has better value incoming links? (less
links but better value)
js and php shouldnt make much diff to PR I thought
the title length should make no diff. i think google just ignores it after a certain number of characters
the number of outgoing links on a page shouldnt make any difference to that pages PR. Only that the PR it passes on is shared between those pages.

Keyword density, titles, etc have no bearing on Pagerank, although they do of course affect your relevance for any given query.
When you say the two sites have nearly identical links, have you checked the PR of each page that has an inbound link?* It would be good to set up a little spreadsheet. And have you taken into account pages with less than PR4 that won't show up in a link:http://www.mysite.com search?
The site structure might also make a difference. Is there a difference in the "depth" of these sites (i.e. how many clicks it takes you to get from the index page to the deepest page?

* i.e. the PR of the other pages pointing to these two sites.
<edit reason>clarification</edit reason>
Right. Here is a good example. In the DMOZ category that both of my sites are, *just* one link from that category is good for a PR of 4. I know of DMOZ categories where one link can do better than that. That Site "A" has 56 links and PR of 3 is pathetic. With a little effort they should have been able to do better than that.
you said: Again, outbound links may affect relevance, but they won't add to PR. Only incoming links will do that.
Pr flows, flow back, gets divided between websites.
if you link to a website that also links to you, that site's pr will increase, and so will the pr of the link back to your site on that site.

It's true that if you link to another site you will have a positive effect on its PR, although in most cases the effect will be very small (unless there is a great disparity in PRs). It's also true that if that site is linking back to you then a small part of any increase in its PR will flow back to you. My sense is that in most cases the effect would be tiny in the end because of the damping factors involved, but I've no way of knowing for sure.
We also have to take into account that by linking outside we are taking away PR that we could otherwise have given to other pages in our sites (which would then flow back to the index page). Again my sense is that this effect would very likely balance out the effect you were talking about.
I'm not arguing against linking to other sites, of course. There are many good reasons for doing so, including boosting relevance by linking to sites that are on the same theme.
(Incidentally, in Scotland when we were playing games or "tag" as kids, we used to say "I'm het" [it]. I wonder how we ended up playing in Dutch?)
Last month i added 15 links to a site, i was planning to make'm javascript, since there is no purpuse in letting Google index my partner urls if i can't adjust the content and make'm rank good.
I forgot to do it, now look; my #1 listing for an other site which is crosslinked with that site went down to #5(and most of the other sites interlinked)
How's that for little? if little is the diffrence between #5 and #1 in compettitive results, i'll take it.
