I don’t discriminate about PR when people request links with me. I do actively seek out higher PR links when I go link swapping, tho.
If it weren’t for high PR pages that linked with me when I started out, where would I be now?
I figure that the guy who has a low PR this month may zip up next month, and the guy with a 6PR this month may zip down next month. It’s always a moving target.
It’s harder to get linked with busy web sites with high PR, simply because the webmasters are besieged with link requests.
It’s easy to get your KW in the title. You tell people what your ‘title’ is – and it doesn’t have to be your url.
Visit all sites you link with and make sure they are quality sites. Look at their code to check for cloaking. (I learned this the hard way)
P.S. this is a personal peeve with me – make sure people can find their links on your site . Alphabetize them or something! When I have to go through page after page of links thrown in with no order – well, I don’t! I just remove their link from my side. Who has the time for that B.S.?
