What is an External Link?

An external link is a hyperlink that points from one website to a different domain. These links are critical for SEO as they help search engines determine the relevance and authority of your content. By linking to reputable sources, you can enhance your site’s credibility and improve its search engine rankings. Simply put, external links connect your content to the broader web, providing value to your readers and signals of trust to search engines.

How Does an External Link Work?

External links work by creating a pathway from your website to another, allowing users to access additional information. When a user clicks on an external link, they’re taken to the linked page. Search engines also follow these links, using them to index and rank web pages. The more relevant and high-quality the links, the better the potential SEO benefits.

Why External Links Matter for SEO

The truth is, external links are a key factor in SEO. They act as third-party votes of confidence, showing search engines that your content is connected to the larger web ecosystem. According to a Moz study, websites with higher external linking activity tend to rank better in search results. So, linking to authoritative sites can give your SEO a boost.

Common Use Cases / When to Use External Links

Use external links when citing sources, providing additional reading, or supporting your claims with data. For instance, if you’re discussing SEO tools, linking to Ahrefs or SEMrush can provide readers with direct access to these resources. It’s about enhancing your content with relevant context and authority.

Best Practices for External Links

• Link to reputable sources with high domain authority.
• Ensure links are relevant to your content.
• Use anchor text that clearly describes the link’s destination.

Common Mistakes to Avoid

Avoid linking to low-quality or irrelevant sites, which can harm your credibility. Don’t use too many external links in a single post, as it could distract readers and dilute your content’s focus.
