Add relevant external links
Outbound links to authoritative sources strengthen the credibility of your content and are considered a positive trust signal by Google. Pages that cite their sources rank better for informational queries than those that make unsupported claims.
Quick Reference
- Link out to authoritative sources that support your claims — this demonstrates E-E-A-T and improves credibility
- External links to reputable sites do not hurt your SEO; Google treats them as a trust signal
- Use
rel="noopener noreferrer"on external links; addrel="nofollow"only for untrusted or paid links
Check
For each content page, count the number of external <a href> links pointing to domains other than the current site. Check: (1) Are factual claims backed by links to authoritative sources (government sites, peer-reviewed research, official documentation)? (2) Do all external links have rel="noopener noreferrer" for security? (3) Are paid or sponsored links marked with rel="sponsored" or rel="nofollow"?
