External links can support SEO by helping visitors find reliable information and understand where your facts come from. They aren't a shortcut to higher rankings, and adding links alone won't guarantee a boost.
For small business owners, the best approach is to focus on usefulness. A relevant link can strengthen a page when it gives readers context they need. Let's look at how to choose those links and avoid common mistakes.
Key Takeaways
External links point visitors to another website, while backlinks point visitors to yours. Both have a place in an SEO strategy, but they do different jobs.
Link to reliable sources when they add value. Use descriptive link text, mark paid links appropriately, and keep your own site's content and technical health in good shape.
How External Links Relate to SEO
Think of an external link as a reference in a conversation. It gives your reader a way to explore a claim, resource, or organization without asking them to take your word for everything.
Google's guidance supports linking to other sites when it makes sense for readers, including when you cite sources. But it doesn't promise that adding outbound links will directly improve your page's ranking.
That distinction matters. If you publish a guide with an important claim, a link to the original source can help visitors understand it. Adding unrelated links just to reach a certain number won't offer the same benefit.
External Links, Backlinks, and Internal Links
These terms sound similar, but each describes a different direction:
- An external or outbound link takes someone from your website to another site.
- A backlink takes someone from another website to yours.
- An internal link connects two pages on your own website.
Backlinks can help Google discover pages and are among the signals its systems use. Our guide to backlink SEO basics explains how they differ from the links you add to your own content.
Internal links also deserve attention. A helpful article can point visitors to a related service page or guide, giving them a clear next step without sending them away from your site.
How to Choose Useful External Links
You don't need an external link in every paragraph. We recommend adding one when another page gives readers information they can't get as clearly from your own page.
Start With a Reliable Source
Choose a destination that fits the claim and comes from a source you trust. For example, a page about paid links can point directly to Google's spam policies, rather than relying on a summary from an unrelated website.
When possible, link to the original document, research, or official guidance. That helps visitors find the relevant details without clicking through several pages.
Make the Destination Clear
The clickable words in a link are called anchor text. Those words should tell readers what they'll find before they click.
For example, "Google's spam policies" gives more context than "click here." Keep the wording natural, and make sure it matches the destination. A reader looking for a policy should land on the policy, not an unrelated homepage.
When to Use Link Attributes
Link attributes tell Google more about your relationship with a linked page. Most ordinary editorial links to sources you trust don't need a special attribute.
Google's outbound-link guidance describes when to use sponsored, ugc, and nofollow.
Paid and User-Generated Links
Use rel="sponsored" for advertising or paid placements. Google also accepts nofollow for these links.
Use rel="ugc" for links added by users, such as links in comments or forum posts. If you manage a WordPress site with open comments, this distinction is useful because visitors can submit links you haven't chosen yourself.
Links You Don’t Want to Endorse
Use rel="nofollow" when the other attributes don't apply and you don't want Google to associate your site with or crawl the linked page.
You don't need to mark every external link as nofollow. A normal citation to a trusted resource can remain a regular link. Your website editor or SEO tools may provide settings for these attributes, so you don't necessarily need to edit code.
External Linking Mistakes to Avoid
The most common mistake is treating outbound links like a quota. A page with several relevant citations can be useful, while a short service page may have no reason to link elsewhere.
We also recommend avoiding paid links that pass ranking credit. Google identifies links created primarily to manipulate rankings as link spam. Excessive link exchanges and automated link creation can fall into the same category.
Lastly, don't leave broken or outdated links in place. A citation that once supported your content may no longer lead to the information your visitor needs. Update the link, find a reliable replacement, or remove it if the source is no longer useful.
Review Links Alongside Your Website’s Health
External links work best as part of a broader SEO routine. Start with important pages and look for claims that need a source, unclear anchor text, and destinations that no longer match your content.
Then review the rest of the page. Is the information accurate? Can visitors reach a related service or contact page? Can search engines find the page through your site's navigation and internal links?
Our local SEO audit checklist can help you review indexing, website usability, and other basics alongside your content.
To measure progress, record meaningful page updates and compare organic clicks in Google Search Console over consistent periods. Treat that as a broader performance check. A change in clicks alone won't prove that an external link caused it.
Frequently Asked Questions
How Many External Links Should a Page Have?
There isn't a required number. Add links where they support the page or help visitors take a useful next step.
Do External Links Send Visitors Away?
They can, because they lead to another website. That can still be worthwhile when the destination helps answer a question or supports a claim. Keep relevant internal links available for visitors who want to explore your services.
Should Every External Link Open in a New Tab?
A new tab isn't an SEO requirement. Choose the experience that makes sense for visitors, and avoid using new tabs as a substitute for helpful link text.
Make Every Link Earn Its Place
External links can make a small business website more useful and trustworthy when they lead to relevant sources. Their value starts with helping the reader, not with chasing a link count.
Review one important page on your site. Look for a claim that needs support or a link that no longer helps. A few well-chosen links can make that page clearer for the people you want to reach.
