Currently I'm building a site's backlinks via: 1. backlink blasts > web 2.0 > my website 2. PBN > my website Do you think (assuming there are no obvious footprints), these 2 methods listed above are the best? I of course also use Twitter/Facebook/Pinterest/Google Plus etc to send social signals to the site. I know the ultimate method is for people to naturally link to you and there be no need to do any Black Hat methods, but I'm referring to giving the website a jumpstart and getting it ranking for easy keywords which in time will help build the site naturally. Would you send social signals to the web 2.0s as well? Do you think there's any benefit of that, assuming the web 2.0 content is well written and of interest to the social media followers?
