Here is a little info about what 3 way link building is and how it works. Three-way linking is a type of link exchange between three websites. Link exchanges that are popular today among webmasters are mostly two-way linking. There are big benefits in exchanging links in terms of SEO, but search engines might not like them so much because they may see them as unnatural. This means that people usually paid to have those links. Why is this bad? Small sites with small budgets won't be able to compete with giant sites with an unlimited budget. Google, as well as other major search engines would like to keep things fare for everyone. (Or maybe they just want to be the only ones charging for links, but you didn't hear that from me.)
Just a side note, did you know there is a such thing as having too many links exchanged on your site?
"excessive reciprocal linking could be considered as a link scheme such as link farms.", seo.com.
Three way links are away to make things seem more natural. How? It is because it involves three websites instead of two. Who's going to pay who in that situation if all three wants to be involved in the exchange. Plus it is a little more difficult to get another site to agree to accept a link that's not even yours
Take Site A, Site B and Site C for example
In a traditional link exchange Site A will ask Site B to exchange links with each other. This is good, but a lot of people pay and charge for link exchange so Google doesn't like that too much.
in a 3 way link exchange Site A will link to Site B, Site B will link to Site C, and Site C will link back to Site A. It will create a sort of web ring between the three. The idea behind this is that even though this is an exchange, they look like one way links, which gives a site a higher value than a site with exchanged links. you can try four-way or even five-way link exchange. It is almost guaranteed that you could get the maximum result to increase your Page Rank.
So how do we do this? First all of the link request should be sent to the web designer or web master so that they can review the sites submitted to them. Every week they will choose the ones they like. After the links are approved, the web master or designer can either accept the link exchange, or offer a three or four way link exchange between your site and the sites that have been approved of. If they trust your site enough to want to exchange links with you, they may trust who you offer to add into this exchange of links.
