If I have a website with 10 categories, and each category considered as a money page, so my PBN should point to 11 links "home page and its 10 categories". So, if my network is 20 site, is it safe for each pbn site to point to 6 links "a home page and 5 internal categories"? This should give me 10 links per every category. I mean, Google will see that every pbn site is pointing to 5 categories of a specific website, is this safe? If no, so how many categories per 1 pbn site do u recommend?
