External Links

External links connect your content to the broader web — they cite sources, recommend tools, and validate claims. When those links break, they create poor user experiences and signal unmaintained content. When external resources are blocked, pages may render incorrectly for crawlers.

These checks audit the health and behavior of every outbound link and external resource reference discovered during the crawl.

Select a topic below to see exactly what the platform checks and how to address each type of external link issue.

Errors

External links returning 4xx client errors, 5xx server errors, or no response — broken outbound links your content points to.

View 3 checks →

Resource Blocking

External CSS, JS, or media files blocked from crawlers — potentially causing incorrect page rendering.

View 1 checks →

Volume

Pages with an unusually high number of outbound external links that may dilute equity or look unnatural.
