Hello, I've got a question in regards of interlinking between sites you own; I am not sure if this is allowed by google if you are using adsense. Let me explain it with an example: - I am in the Book niche. - I have 4 websites. 1 - eCommerce; the mother website; here I only discuss about books in general without any SEO purpose. 2- Horror books; mns; i discuss horror books and i use SEO to optimize the page. 3- Science-Fi books; same as above. 4- X books; same as above. What do I do? Each of the mns (2,3,4) contain one link to the mother website (1). The link in show in the following manner: If you wish to learn more about other book styles follow this link -Link-. The mother website as well as being an eCommerce, it has a section on the homepage under which says: If you wish to learn more about horror books follow this link -link to horror book site- Same for the other 2 sites. A while ago I read about private networks and how interlinking among each other will get them deindexed. Questions (using adsense + google for ranking): - Is this considered as a private network (imagine we are talking about 20 sites and all of the mns have pr 3+). - Is this allowed, meaning, will this get me penalized? Thanks in advance!!!
