I have a question regarding T1 links. I try to get as many kind of links that bring power to my MS as possible. I know of PBNs and manually build web20. My question is what other sort of links it is worth getting. Especially those which can be gained for free and not with automated tools. Not an easy start for someone with a low budget If I focus on getting profile and bookmark backlinks - will it bring any power to my website? I know a lot of sites where you can create a profile for free and place a backlinks to your site. I assume that those links would be d0follow and coming from authority sites. Also since I am not into automated tools is it actually worth building web20? I read that such subdomains have no power at all and are treated like a new domain so I would need to build links to them, correct?
