What are external links?

External links are hyperlinks that lead from your site to other web resources, or the other way around. They can be placed on your site and point to other sites, or placed on other sites and point to yours.

In simple terms: external links are like bridges between different sites on the internet. Picture every site as an island — to get from one island to another, you need a bridge. External links are exactly that kind of bridge.

What are they for?

  • Endorsement:
    When one site links to another, it can be read as a recommendation. If a lot of “good” sites recommend yours, search engines conclude your site is “good” too, and rank it higher in the results.
  • Extra visitors:
    People reading an article on another site who spot a link to yours can click through and land on your page. That drives up the number of visitors to your site.
  • Usefulness:
    If your site links out to other useful resources, that makes your site more useful to visitors. They’ll feel that you’re genuinely helping them find the information they need.

Why do external links matter?

Boosting authority

Links from authoritative sites can raise your own site’s authority in the eyes of search engines. That, in turn, can improve your ranking in search results.

Additional traffic

External links can bring new visitors to your site. This is especially effective when the links are placed on sites that are relevant to your content.

Better UX

Having external links to useful resources can improve the user experience, making your site more informative and helpful.

Best practices

Choosing authoritative resources

Try to earn links from authoritative, relevant resources. This improves the quality of the “link juice” you receive.

Anchor text

Use relevant anchor text for your links. This helps search engines understand exactly what’s behind that link.

Don’t overdo it

Too many external links can look suspicious to search engines and may lead to penalties.
