I have been wondering about this for a long time because I'm wanting to get a site up and running in which I get a pretty high PageRank and then I would like to link out to tons of sites. If I were to create a site that ended up having like 100+ outgoing links on the homepage and it had a PR4 or something, what would happen to it? Would my sites PR4 go down as a result of so many outgoing links on the home page (and then thousands more on other internal pages) or would it just decrease the value of each link on the page? This is a questions I've actually been wondering for a while. Is the increased number of outgoing links on a page going to hurt the page itself or is it simply going to decrease the value of the link to the sites it links to? All links will be dofollow.
Each link takes some of your pages page rank. 100 links is not good on any site so if you do link out make it like 20 links on a page.
So it's going to hurt my pagerank? I'll start off with a PR4 and it will decrease as links get added? Does it make a difference if the links on the page are going to cycle rather frequently, after it gets started, ideally, no link would be there more than an hour.
I think it will decrease the pr of your page, because Google think it is a link from your site and consider the value of this link.
Alright, well I'll probably reduce it a bit or to none. We'll see what I need to do to get my project to work. It's not for boosting my sites or anything but the actual concept of my site with PR involves lots of outgoing links.
rough estimate for PR weighting: Go to your webmaster tools account and see the inbound links recognized by google, then scan their PR with something like seo tools>link checker Now if your PR4 page (I'm presuming it's the index home page) has say 10 PR5 dofollow inbound's then consider dividing inbound's/outbound's of your potential links for your index. example: PR five links are (10) thus 10/8 outbound index page links = 1.25 it's important to keep this above 1.00 so if you decided to create say 18 outbound's then: 10/18 = 0.55 and your in the danger zone to lose a PR point. Note: it's best to understand this as if the outbound's are oneway and are not reciprocated, if they are however then you could probably allow more outbound's without jeopardizing your Page Rank. I utilize this quite a lot and try to keep my score at above two, just to be on the safe side. A broader example can be seen at http://en.wikipedia.org/wiki/PageRank#Simplified_algorithm From the example above you should be able to calculate the maximum safe number of outbound's without affecting your Ranking. mixed PR scores can be aggregated into the sum given too.

I have actually seen high traffic, authority blogs with hundreds of outbound links with no apparent harm to their page rank. It is all about quality.
and also their 100k plus inbound's that they've probably accumulated over the past several years or so, that is if they're a genuine high traffic authority blog. ROOFIS
