Link building (alternative spellings include linkbuilding and link-building) refers to the process of getting external pages to link to a page on your website. It is one of the many tactics used in search engine optimization (SEO).
The most common analogy of a link is to liken it to a vote. If page A links to page B then page A is suggesting page B is a good page, page A likes page B. The only slight complication is the nofollow tag. In a nutshell the nofollow tag allows links to be added to a page that create a click-able link to another page without the link passing a vote. These are used for text link adverts for example where they will send traffic to another page without passing a vote.
I'm not going to go into any more detail on the nofollow tag here but I'd strongly advise reading the WikiPedia page for an in depth explanation. In short if you want to link from a page on your site to a page on another site without inferring any kind of endorsement use the nofollow tag.
