Doing a website design, and my client is under the impression that if he links to my website that he'll "bleed" his own pagerank.
In other words, his pagerank is 4, and he's been told that each time he links out to another website, his pagerank drops.
Does anybody have a link to an authoritative page (something straight out of Google is preferable) that clearly states that outgoing links do not lower your website's pagerank?
The more authoritative the better. I've sent a couple links, but he won't change his opinion without something conclusive.
Thanks in advance
