An External Link is a hyperlink that points from one domain to a completely different domain. In other words, it’s a link that takes users away from the current website to content on another website. External links can point to or from your site, and they play a crucial role in both SEO and user experience.
Going Deeper: Why External Links Matter for SEO
In SEO, external outbound links (links from your site to others) and external inbound links (links from other sites to your content) carry very different weight:
- Outbound External Links:
Improve user trust and credibility when linking to authoritative, relevant sources (e.g., industry publications, research, government sites). These links help search engines understand the topical context of your content.
- Inbound External Links (Backlinks):
These are among the most important SEO ranking factors. The more high-quality external sites linking to your content, the more trustworthy and authoritative your site appears in the eyes of Google.
Proper use of external links can enhance:
- Content credibility and value
- Search engine trust
- User experience and resourcefulness
Examples in Practice
- A roofing company blog links to the National Roofing Contractors Association (NRCA) to support facts about safety standards—an outbound external link.
- A government website links to your local SEO guide as a trusted resource—an inbound external link, boosting your domain authority.
- A low-quality site links to yours with spammy anchor text—an example of an external link you may need to disavow.
