I want to make around 10 different Web 2.0 Sites that link to my money page. But I don't just want to use the simple grayhat approach to Web 2.0 linking where I link to other sites and one or two times to mine. I want to use each Web 2.0 site to link to 1 or 2 specific URLs of my money page. But not only one time. I want to link every week with a new spinned post with relevant content. A little bit like using the web 2.0 sites as social media platforms or as microsites to a specific topic. My plan is to make three spinned and relevant posts per week (800+ words) and link to other authority sites like wikipedia or facebook. But one time per week or maybe only every second week, I link to the specific URLs of my money site. If I provide enough content 2000+ words on homepage, images, sometimes videos and unique (spinned) content, is Google going to see this as blackhat linkbuilding? Because it is backlink building, but if I link every week from my company tumblr, twitter or linkedin account you could also say it's linkbuilding. And if I provide a lot of unique content and only link every week or every second week to my site, shouldn't Google be pleased? I don't have the time and money to test it on another domain, but I want it to be safe. What is your experience with similar link building strategies? What is the best way to benefit from a microsite regarding SEO without getting banned?
