Hi guys, Please entertain the following hypothetical situation: I have a keyword that I want to rank with medium competition. Part of my main link building strategy would involve building 8+ web 2.0 sites around that keyword and linking to my main site. I would then seek to build up the Web 2.0s authority by sending social bookmarks, blog comments etc to them.. Let's also say I build some other links but the "strongest" are the Web 2.0s. My question is.. do I use my main keyword to link to my site from the Web 2.0s? Since they would be the "strongest" links right off the bat, I fear that Google would see this as a little odd since these would be the most "authoritative" links (comparatively). Generally speaking, my inclination is to create an anchor text link on the higher PR domains but I also fear that this looks too unnatural to Google.. but perhaps it doesn't. So I'm wondering do you guys typically place your primary targeted keywords on the more authoritative web properties such as Web 2.0s? And when might it start looking like obvious manipulation?
