I've been using web 2 properties for link building and it's been working well, but I just had a bunch of Wordpress blogs deleted for spam and it's making me rethink how I go about this. I'd appreciate any advice on the following: If you're using web 2 properties as your first tier - 1. Is it important that they be related to the topic of the money site you're linking them to? 2. Is it best to create a new set of properties for each project (like one for each money site)? 3. How many links to the money site do you put in each post? 4. How many posts do you need, and how often do you need to add posts? Thanks!
