When the biggies go crawling the web, I understand they look in websites for links and things like signing guests books and forums where the URL is shown (in a signature), but do they also pick up the URL on e-mails? Where else might they be looking? Also, and I'm not sure if this is legal, but someone I know, to get the pages higher up on the food chain, suggested exchanging links by putting a dot way down on the page, and in the same color as the background so it won't show and would be highly unlikely someone would roll over it. What's your read on doing that? Doesn't sound right to me.
