Obviously, a site needs to have great content filled with SEO keywords and landing pages. But what are the best ways to increase search engine ranking by using other sites/blogs? I have looked into various gigs on Fiverr and also the profiles of several freelancers on oDesk that offer services related to SEO and increasing search ranking via backlinks. But it has been hard to figure out exactly what they do, and I feel uncomfortable asking total strangers earning poverty wages to handle this. I own about 50 different domains that I have no utility other than to help me promote other "real" sites. What are the best ways to use these sites? For example, is it helpful or harmful to setup blogs on these sites with articles that link back to the main sites that I want to promote? Since I own these domains, I would love to figure out how to best utilize them in a way that increases the organic ranking of my main sites.
We would probably need more information to really answer this fully however in general I would say to make sure that all 50 citation page entries are entered exactly the same and complete. If you don't know where to find those drop me a note and I will share the information.
