I've heard different schools of thought on this and wondered what people think. When creating pages on content sites such as squidoo, hubpages, weebly etc, one suggestion was for them all to link back to your “main†website. Another suggested linking all the content sites together randomly, while also linking back to your main site from each one. But recently I have read that this is a bad idea as it can leave a footprint with Google, if they can see all these content pages linking together, and pointing to one site. What do people here do with their content sites in terms of linking? Thanks everyone.
