Broken Link Checker

What this checker does

Paste the URL of one page, usually the landing page you are about to launch. EarlyHunt fetches that page from its server, reads the anchor tags, and requests each unique http or https link. Relative URLs are resolved against the final page URL, including a base tag when the HTML has one. mailto, tel, javascript, and links that are only #anchors are skipped. The same URL is checked once, and the first anchor text is kept.

The checker does not run JavaScript, click buttons, or submit forms. A link that exists only after a script runs is not in the server HTML, so it is not in the table. The checker also does not crawl onward: it requests a link to read that response, and it does not collect the links on the destination.

How to read a row

OK means the final response was in the 200 range and the URL did not redirect. Redirect means the checker followed a 301, 302, 303, 307, or 308. The final URL is shown so you can see where the link lands. A redirect that ends on a 404 is broken, not a successful redirect.

Broken means a 4xx or 5xx status other than 403 and 429. A 404, a 410, and a 500 are broken. Blocked means the checker refused the address, or the site answered 403 or 429. Those two statuses usually mean an automated client was refused, not that a visitor would see a missing page. Timeout means no status code came back: the host did not resolve, the connection failed, or the time limit was reached. A timeout is not labeled broken.

Limits

At most 150 unique links are checked. If the page has more, the result says so and the rest are left unchecked. A handful of links are requested at a time, each with a short timeout. The page HTML is read only up to 1.5 MB.

Internal means the link host matches the page host. A leading www is ignored, so www.example.com and example.com are the same host. A subdomain such as docs.example.com is external, which keeps a dead docs host visible in the table.

Some sites block this user agent. When they do, the row says blocked. Open that URL in a browser before you treat it as a problem on your landing page.

Before you launch

1. Paste the exact URL you will share, including https.
2. Fix broken rows first. A 404 or 410 fails for visitors too.
3. Open each redirect and confirm the final URL is the page you intended.
4. Open blocked and timeout rows in a browser. A 403 or 429 often means the site refused this checker.
5. Run the check again after you edit the page. Only the URL you paste is fetched.

When the rows you care about are clean, check the images in the Launch Image Size Checker and pick other directories in the Launch Directory Finder.
