We have a set of 150 blog sites (5 blogs each roughly per site). We want to build the pagerank and backlinks to these sites. Please make a proposal for blog SEO, that could include listing with blog directories, use of services such as entrecard, etc. What we want is something cost-effective, since we will utilize this link-building method with the provider for 500-1000 blogs. But I will leave open to you in your proposal what techniques you recommend. I would prefer to take advantage of some SEO techniques unique to blogs (not just general techniques available to all websites). Thanks.
