When it comes to how your network is actually going to work in your favor, you can use web 2.0 links as a tier 1 (buffer sites) or as a tier 2. Tier 2 links still pass on some link juice, although many people don’t seem to think so.
A tier 1 blog would be the buffer site between your money-making website and another, such as one from your private blog network, for example. This one is highly recommended as you can’t really assess the health of a PBN link, especially if it is owned by someone other than yourself.
A tier 2 strategy would involve you building one or two blogs, for example, and then adding a link in one of your posts — but wait, the link isn’t directly aimed at your website. Instead, it is pointing to another website, one you’ve acquired a link from (like a guest post, a PR link, even a local citation site).
