I'm getting ready to rebuild a lot of my sites using the information I have gathered here this year. Trying to get everything set up for my yearly New Year's Resolution to make tons of money and quit my job. I mostly build affiliate type sites with WP and link to CB affiliate items, adsense, ebay EPN and I've just started adding a few CPA offers. When adding links to affiliate products is it worth the trouble to add the nofollow attribute? One of the things I want to add on my rebuilds is the link*u*bator. Do you think the search engines care if I have a lot of "leaks" from my site?
