External links

External links are hyperlinks on a website that point to a page on a different website. They are used to direct users to additional resources or related content outside the current website. For example, if a blog post links to a study or article on another site, that link is an external link.

External links are valuable for both users and SEO. For users, they provide additional information or sources, enhancing their experience and understanding of the topic. For SEO, external links to reputable sites can increase a website's credibility and signal to search engines that the content is well-researched and trustworthy.

When a website links to high-quality, authoritative sources, search engines view this as a positive ranking factor. However, linking to low-quality or spammy sites can harm SEO, so it’s essential to choose sources carefully.

In summary, external links connect users to valuable content outside the website, improve the site's trustworthiness, and can positively impact SEO if used responsibly.
