Link building is the process of acquiring hyperlinks from other websites to your own. A hyperlink (usually just called a link) is a way for users to navigate between pages on the internet. Search engines use links to crawl the web; they will crawl the links between the individual pages on your website, and they will crawl the links between entire websites.
We have three types of Link-Building like 1 way, 2 way and 3 way which mentioned below.
Except one-way link-building, In the remaining two Link-Buildings if any website will hit by spam means then remaining sites also will be hit by spam. So one-way is the best way to do Link-Building. By doing the Link-Building, we will get the good PR value, with the PR we use to get the good position in Google, if the position is good means then the Bounce Rate will be reduced.
