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). Building links is a difficult, time-consuming process as not all links are created equal. A link from an authoratative website like the Wall Street Journal will make a greater impact on a SERP than a link from a newly built website, but high quality links are hard to come by.

I think Link Building is a good thing for big online companies that have a lot of writers and can't invest all the time in good content (you can't trust people will always make amazing content) and you hire somebody to do Linkbuilding, to get good links from authority sites. But if you are a blogger, a single person, I think it is better to focus on the content. Because if you make a really good piece of content, people will share it, link to it, without you wasting the time for it.

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. There are many techniques for building links, and while they vary in difficulty, SEOs tend to agree that link building is one of the hardest parts of their jobs. Many SEOs spend the majority of their time trying to do it well. For that reason, if you can master the art of building high-quality links, it can truly put you ahead of both other SEOs and your competition.
