How to Fix: External links present

External links present is an important SEO check in the On-Page SEO Essentials category. This is a lower-priority optimization. Address it after handling more critical issues.

What this check is really about

This check looks for outbound links from your content to other websites. It surprises people, because the instinct is to hoard link equity and never send anyone away. But a page with zero external links reads, to a search engine, like a page written in a vacuum — no sources, no references, no acknowledgement that the rest of the web exists. Genuine, well-researched content naturally cites things. The absence of any outbound link is a mild but real signal that the page might be thin or self-contained in a way real expertise rarely is.

I will be straight about the weight here: this is a lower-priority check, and correctly so. Nobody ranks or tanks on outbound links alone. But it is a cheap quality signal to get right, and the act of adding good sources usually improves the content itself, which is the part that actually moves rankings.

Why it matters for SEO

• Linking to authoritative sources is a trust and quality signal consistent with well-researched content
• Relevant outbound links help search engines understand your page’s topic and neighbourhood
• Citing sources builds reader trust directly, which lifts engagement and return visits
• Adding references almost always forces you to strengthen the underlying claims, improving the page

How to check whether you have this problem

Open your key content pages and count the outbound links to other domains. Zero on a substantial article is the flag. While you are looking, check the quality: a link to a primary source, a standards body, or original research is worth far more than a link to a random low-quality blog. The SEO Roadmap audit flags pages with no external links so you can prioritise your most important content first.

How to fix this in WordPress

Difficulty Level: EASY – This fix is straightforward and can typically be completed by anyone with basic WordPress knowledge.

Estimated Time: varies

Step 1: Link to real sources, not filler

Go through the page and find the claims that deserve a citation — a statistic, a standard, a study, a tool you referenced, an official documentation page. Link to the primary source wherever possible. The goal is not “add three links to hit the check”; it is to point the reader at where your claims come from. If a claim has no credible source, that tells you something about the claim.

Step 2: Set link behaviour sensibly

Open external links in a new tab where it helps the reader keep their place, and add rel="noopener" for security when you do. You generally do not need nofollow on ordinary editorial links to reputable sources — reserve nofollow or sponsored for paid or affiliate links, which is what those attributes are actually for.

Step 3: Keep the links alive

Outbound links rot over time as other sites move or remove pages. A broken-link checker run periodically keeps your citations pointing somewhere real; a page full of dead external links is worse than a page with none.

Step 4: Verify

1. Confirm each important page now links to at least one genuinely relevant, authoritative source
2. Click the links to make sure they resolve and point where you intended
3. Clear your cache so the updated content is served
4. Re-run the SEO Roadmap audit to confirm the check passes

What I would not do

• Do not add random links just to satisfy the check — a link to a weak source is worse than no link
• Do not blanket every external link with nofollow; reserve it for paid and affiliate links
• Do not link so heavily that the page reads like a link farm; a few strong citations beat a pile of weak ones
• Do not set and forget — dead outbound links accumulate and quietly hurt the page
