Extract URLs from Text

In short Extracting URLs finds every link in text or HTML, removes duplicates, and can group them by domain or strip tracking parameters. The tracking option is the one worth using by default. Query parameters beginning utm_, plus fbclid and gclid, are added by the platform that sent the traffic and are not part of the destination — two links to the same page with different utm_source values are the same URL, and deduplicating without stripping them leaves you with a list that looks longer than it is. Grouping by domain answers a different question quickly: which sites does this document actually point at, and how many times. That is the fastest way to audit a page's outbound links or to see what a competitor's article cites. Two limits. A URL written without a scheme, such as example.com/page, is ambiguous — it is matched here, but text is full of things that look like bare domains and are not. And relative links in pasted HTML have no domain to resolve against, so they come out as written.
