External Links SEO
External links are hyperlinks from your page to a different domain, used to support claims, guide users, and reinforce topical credibility when pointing to relevant, trustworthy destinations.
If you have ever done external linking just to increase the number, you already know that relevance and trust matter more than any count.
Key points
- Link to relevant, trustworthy pages to support your claims and improve user experience.
- Use descriptive anchor text so users know what the linked page is about.
- Use a nofollow link for untrusted or paid links, and rel="sponsored" for sponsored content.
- Check for broken external links regularly as they harm usability and quality signals.
- Do not worry about a fixed number of external links; usefulness over quantity.
The same external link, two different effects
A travel blog includes a link to an official tourism board page for a destination. That link uses descriptive anchor text 'visit the official tourism site for Japan' and points to a high-authority .gov domain. Users click it for more information, and search engines see a relevant, trustworthy outbound link. In contrast, the same blog adds a link to a low-quality forum with vague anchor text 'click here'. That link provides little value and may harm credibility.
Three things external links are not
- Not a ranking shortcut External links do not directly boost rankings. Their value comes from relevance, trust, and user experience, not from simply having many outbound links.
- Not a fixed count There is no optimal number of external links per page. Adding links for the sake of quantity can dilute user trust and harm the page's quality.
- Not always followed by search engines Links with rel="nofollow", "sponsored", or "ugc" tell search engines not to treat them as backlinks for ranking. Use these attributes appropriately.
Three ways to get external links wrong
- Linking to low-trust sites Pointing to spammy, irrelevant, or low-authority pages can damage your own page's credibility. Always verify the destination's trustworthiness.
- Using vague anchor text Anchor text like 'click here' gives users and search engines no context. Descriptive anchor text helps them understand what to expect.
- Forgetting to check for broken links Broken external links frustrate users and weaken quality signals. Regularly audit your outbound links with a link checker.
Common questions
How do external links help get your site indexed?
External links from your site to others do not help indexing. For indexing, use internal links, sitemaps, and request indexing via Google Search Console.
How can you get external links to your website?
This entry covers outbound links from your site. For links pointing to your site (backlinks), focus on creating content others want to link to.
