Great stuff - thanks! Okay, back to my question. Let's say I have a PR4 links page and it has 100 outbound links on it. Half of them are being reciprocated by PR3, PR4, and PR5 pages, but the other half are being reciprocated by
PR-zero pages. Would it be a good idea to dump the 50
PR-zero trades? Or does it matter?
Of course I like to offer good relevant links to my site visitors, but let's face it, I have to put food on my table too. Right now all my sites are enjoying number-one spots on Google for the most part. But a few of them are still climbing.
I've done some extensive research on this subject, and I have found that sites with a lot of inbound links and very few outbound links usually have higher PageRank than sites with the same amount of inbound links but more outbound links. This would contribute to the "PageRank leakage" theory. However, I know that Google has a PR10 and they are linked to virtually everyone. That fact seems to tear apart the idea of losing PageRank due to linking to sites with lower PageRank.
Any thoughts?
