I've an idea and would like to share it here. One of the best link building strategies is to create our own link network and we want the network to be distributed on different class-c ip. That's why we have some seo hosting companies offering what we want. But they're very pricy. My idea is, if we have a vps or reseller hosting account, why don't we just exchange cPanel accounts. If we are in different hosting company we're likely to have different class-c ip too. Does this sound interesting? Let's discuss about it.
