link Building is also called creating backlink .When you have created good quality content and properly optimize it then the next step comes is making a link. This step is important because if the content has quality but google did it not crawled it then there is no benefit in doing this.when your site gets link from an authority site then your site's authority automatically starts improving.

Link building, simply put, is the procedure of getting other websites to link back to your website. All marketers and business owners should be interested in building links to run referral traffic and increase their site's authority.

Why build links? Google's algorithms are complicated and always evolving, but backlinks remain an important factor in how every search engine determines which sites rank for which keywords. Building links is one of the many tactics used in search engine optimization (SEO) because links are a signal to Google that your site is a quality resource worthy of citation. Therefore, sites with more backlinks look after to earn higher rankings.

There's a right way and a wrong way, however, to build links to your site. If you care about the long-term viability of your site and business, you should only engage in natural link building, meaning, the process of earning links rather than buying them or otherwise achieving them through manipulative approach (sometimes known as black-hat SEO, a practice that can get your site essentially banned from the search results).

That said, natural, organic link building is a difficult, time-consuming procedure. Not all links are created equal: A link from an authoritative website like the Wall Street Journal will have a higher impact on your rankings on the SERP than a link from a small or newly built website, but high-quality links are tough to come by.

This guide will instruct you how to build quality links that improve your organic rankings without violating Google guidelines.

Remember, link building is essential in achieving high organic search rankings.
