What Are Backlinks and Why Are They So Important for SEO

Introduction

If SEO were a popularity contest, backlinks would be the votes. A backlink is a link from one website to another — and Google treats these links as endorsements. When a reputable website links to your content, it’s essentially telling Google: ‘This page is trustworthy and valuable.’ The more quality backlinks you earn, the higher Google tends to rank your pages.

Why Backlinks Are Google’s Most Trusted Signal

Google was built on the idea that links are votes of confidence. In the early days of the internet, Google’s founders noticed that the most-linked-to pages tended to be the most authoritative. That principle still holds today. While Google now uses hundreds of ranking signals, backlinks remain one of the top three most important factors.

Quality vs Quantity: Which Backlinks Actually Matter

One backlink from a highly trusted website like Forbes, HubSpot, or a major news outlet is worth more than 100 links from low-quality, irrelevant websites. Google looks at the authority, relevance, and trustworthiness of the linking site. Focus on earning fewer, high-quality backlinks rather than building hundreds of spammy ones.

Types of Backlinks: Dofollow vs Nofollow

Dofollow links pass ranking power (called ‘link juice’) to your site — these are what you want. Nofollow links include an HTML attribute telling Google not to pass ranking power. Social media links and many news site links are nofollow. While nofollow links don’t directly help rankings, they still drive traffic and build brand visibility.

How to Start Earning Backlinks as a Beginner

The most sustainable way to earn backlinks is to create content worth linking to — original research, detailed guides, or genuinely useful tools. Other strategies include writing guest posts for other websites in your niche, getting listed in industry directories, and reaching out to bloggers who mention topics you’ve covered to suggest linking to your in-depth article.

Backlinks to Avoid at All Costs

Buying links, using private blog networks, or participating in link schemes are against Google’s guidelines. If caught, your site can be penalised and rankings can drop dramatically. Avoid any service that promises hundreds of backlinks for a small fee — these almost always use black-hat methods that will harm your site in the long run.
