So I'm planning to create a good web 2.0 pyramid using blogs (wordpress and tumblr) tier 1: 13 wordpress blogs. tier 2: 25 tumblr blogs. tier 3: 50 wordpress blogs. Now, I want to point each property to all the units of the above tier. so let's say each wordpress blog of tier 3 will point to the 25 units of tier 2... My question is... is it ok to create an article and throw the 25 links with proper anchor text? I don't want it to look suspecious.. Do you actually do this with your pyramids? do you think it should be effective? thanks in advance..
