Part 1: What is a Backlink? Why is it important in SEO?

In its simplest definition, a backlink (also known as an inbound link or inbound link) is a link from another website pointing to your website.

Imagine this: Every time another website links to content on your website, Google considers it a "vote" or a recommendation about the trustworthiness and value of that content. The more reputable websites link to your website, the more Google appreciates your website's trust, authority and relevance to a certain topic.

Why are backlinks important in SEO?

  • Powerful ranking signal: Backlinks have been one of Google's most important ranking factors for many years. The quantity and especially the quality of backlinks directly affects your website's ranking on search results.

  • Increase credibility and authority (Authority): When reputable websites in the industry or related links to you, it helps increase the credibility and authority (Domain Authority, Page Authority) for your website in the eyes of Google.

Part 2: Common Types of Backlinks

In the world of backlinks, there are some basic concepts you need to know:

  • Dofollow Backlink: This is the standard, default type of backlink. When a website links to you with a dofollow link, it "transfers" some of the power and trustworthiness (often called "link juice" or "link equity") from that website to your website. This type of link has high SEO value.

  • Nofollow Backlink: This type of link has the rel="nofollow" attribute added. It's still a link from another website to you, but it requires Google not to "pass on" link juice and not count it as a vote for ranking purposes. Nofollow backlinks are often used for paid links, links in comments, forums, or social media platforms. Although it does not directly affect rankings like dofollow, nofollow links can still bring referral traffic and help diversify your backlink profile.

  • Natural Backlinks: Are backlinks that your website receives naturally, not through exchange, purchase, or direct request. This happens when your content is really quality, useful, and other websites voluntarily link to it because they find the content worthwhile to share with their readers. This is the type of backlink that Google values the most.

  • Manual Backlink: Are backlinks that you actively build through activities such as guest posting, registering for business directories, promoting content for others to link to.

  • Increase Authority Real Trust: Google wants to see your website "endorsed" by other trustworthy sources. Quality backlinks that come from relevant websites and are used by real people will help increase the real credibility of your website.

  • Create High-Quality, Unique and Useful Content: This is the most natural and sustainable way to build backlinks. When your content is truly valuable (in-depth research articles, infographics, detailed guides, ebooks...), other websites will voluntarily link to you as a reference source.
