How do deep links affect overall site PR

Do deep links raise PR of homepage?

[greenfrog]

I am trying to get incoming links to build the PR of my site. I have received many that point directly to my homepage, and those links have raised the PR of my homepage.

What affect would it have if I began to get external links for a page that is deep within my site. Would this boost the PR for my homepage, and/or the entire site?

It seems like most ppl send links directly to the homepage?

Good question. Was wondering the same thing too. I am about to launch a campaign to get people to start "deep linking" to a newly launched section of a site. Will this only effect the pages withing the deep link.. or will it propogate back up to the main page?

I believe it depends on the link architecture how PR is distributed within the site and what benefit would be derived.

It should propagate to the HP exactly like it propagates to the subpages when linked to the HP.
Of course it always gives more PR to the directly linked page.

I'd suggest: If you already do fine on the HP have some deeplinks (for keyword reasons).
You can feed google with more targetted keywords when deeplinking.

If the linking site has much PR : link to HP
If the linking site has little PR : deeplink

But that's just a feeling, no scientific reason :)

I prefer deep links, because surfers are directed to the content they want. Each interior page links to the root index page, so surfers can easily find it, no need for detours. Since I lose (scanning) visitors looking for particular content via incoming HP links, I always try to get deep inbounds from related pages.

PR wise I may see a slightly lower boost on the root index, but I value targeted traffic higher than PR. A surfer friendly navigation will pass all incoming PR to the right targets by the way, regardless where the point of entry is located. I know a few high PR index pages getting the majority of their PR from interior pages which are deep linked from outside.

Another point is keyword relevancy, deep inbounds produce a nice amount of interior pages which rank fine for two and three word keyword phrases. Probably these deep linked pages bring in more (targeted) traffic than HP inbounds.

Just my 2 cents.
