One way link is a link that points from one web page to a page on someone else's website. For example, site A links to site B
If there is a mutual understanding between two webmasters and they consent to exchange links with each other, It becomes two-way linking or reciprocal linking. For example, A links to B and B links back to A.
Nice information! Thanks a lot!
