Three-Way Link Exchange is somehow similar to two-way link exchange but the difference is instead of putting a link to another site on your own site, you will place its link on the other site you have. Sounds complicated? Let me discuss it furthermore.
Three-Way link exchange is a cultivated term not a generic term. This term is used in case when more than two pages are involved in linking. It means that Page A is linking to Page B and Page B is linking to Page C. But Page B is not linking to Page A and Page C is not linking to Page B.
This is usually done when you own two websites. One website has already many back links and page rank and the other one don’t have many back links and/or don’t have page rank. You put a link to another site on the website that has already many back links and/or page rank and in return, your link exchange partner will put a link of your site that doesn’t have any page rank yet.
This type of link exchange is best done when you have a new website and you want to have a good page rank as soon as possible. Of course, that still depends if your link exchange partner has established a good page rank already. So be sure to choose a good and well optimized website before you ask to trade links with its webmasters.
Some webmasters are also using four way link building methods, however, this is not yet advisable since it’s already complicated and it’s already hard to keep track of your inbound links and link exchange partners. So in the meantime, be free to use the common link exchange strategies since it’s already tested.
