Hi All,
After a long time em going to post something about three way linking or 3 way linking . Now days its very popular and useful then reciprocal linking .
In three way linking three website involves
Lets suppose A,B and C are three website .
Now A Exchange link with B and B will ask A To instead of adding B link Add C Link on A links page so this way A,B and C linked with each other and search engine consider them as one way linking cus not each of them have reverse linking with each other hence its most useful method .
Let me Explain yo one more time about 3 way linking.
let suppose you have a website Called “A” and You exchange your link with another website “B” , Here “B” will ask you to add another website “C” instead of adding “B” into “A” link page so “A”, “B” and “C” will linked each other and google will consider them one way linking 
Because “A”: >>linked with >>”B” >> linked with “C” and “C” Linked with “A” . This method is more useful and effective then reciprocal linking in which “A” And “B” only 2 website linked with each other and have reciprocal links etc . Hope u understand this technique .
Hope you like it more post coming soon
