📌 External Link Checker API

The External Link Checker API helps developers, SEO specialists, and site owners programmatically analyze how a given webpage’s external links behave. It scans a page, extracts links that point to other domains (i.e., not internal), and checks their HTTP response status codes (such as 200 OK, 404 Not Found, etc.). The API might also detect issues like broken links, redirects, or unreachable hosts.

Detecting external link issues is valuable for maintaining a clean outbound link profile, improving user experience, and preventing SEO penalties caused by too many dead external links. A properly working external links report can be integrated into site monitoring systems, SEO dashboards, and automated content pipelines.

This type of API generally returns structured data (often JSON) listing each external link along with its status, error indicators, and possibly suggestions. Tools similar to this can also categorize external links and provide insights into link authority and SEO relevance.
