A reciprocal link exchange (two way link building) is linking that happens between two industry relevant websites. In a reciprocal link exchange the two websites have to agree to link to one another. Reciprocal link exchange is only a give and take process where both websites are industry relevant and share the targeted traffic.
One way to improve the ranking your website receives in a search and to bring more visitors to your site is a method known as 3 way link building. This is a somewhat more complicated system than other link building methods, but it is also the most effective of them all and worth whatever it takes to set up. It also has the advantage of being accepted by search engines, unlike the other link building methods which are no longer being calculated into the results of a search.
