When you are thinking of link building for search engine optimization you can also think of obtaining the assistance of the affiliate programs Google AdWords and other Ad Buys. You can buy links from Google Adwords that will create your link building process for search engine optimization. In some of the cases you will also get organic links and this will create awareness leading to more usages and more links.
One more process that could be immensely beneficial and that depends on the text links is linking out to the egomaniac bloggers. This is another way of your buying links and diverting most of your attention to distribution. You will be cashing on by satisfying the ego of such people who like some form of recognition. This will be a method of building up two-way links.
Other such affiliate methods that could be used for link building with or without powerful links like the edu text links could be blog carnivals, press releases and buying the brands or the entire site. In Blog carnivals a group of bloggers discuss about certain topics and they make a mention of the same to every other in the arena that creates good link for you. Press releases can create interest in others about your site and thus create useful links for you.
Nothing above could however really be a substitute for a good provider selling out the links to you that would be genuine and not spam and giving you real search engine optimization in the process.
