I have a new site that I am promoting with several main keywords that are each going to require a campaign involving a link pyramid and web 2.0's. I have a few easy questions and I'll greatly appreciate if someone could give me some pointers. 1. Spun content. Say I spin an article 50 times. Would it be okay to have 50 properties each with one version, even if there are other articles on the site, or is that a footprint? What about posting 3 spun versions of the same article for one web 2.0 property? 2. How much content is required to look natural and not cause penalties? Could you just post 1 article per web 2.0? 3. What if I had a web 2.0 with 3 articles on various aspects of the same main keyword, each linking back to my money site? Are multiple backlinks to your money domain okay, or even beneficial? 4. Say I have my web 2.0, with 3 articles on different aspects of my keyword. If I spun this content, and created 30 more 2.0's each with the same 3 articles, but spun, will this result in a penalty? tl;dr: Basically I just need to understand how similar spun content is viewed across several 2.0's, if multiple links towards your money site on the same property are okay, the minimum amount of content, and if content on the same site/all sites can be closely related or even the same spun version.
