Link & Anchor Checker (Single Page) — frequently asked questions
What does the deep broken link checker inspect?
The checker discovers all hyperlinks (`<a href="...">`) on a page, validates absolute and relative URL formats, checks internal anchor fragments (`#heading-id`), and flags mixed HTTP content.
What are broken anchor fragments?
An anchor link pointing to a hash target like `#pricing` is broken if no element on the destination page possesses that corresponding `id` attribute.
What is mixed content on HTTPS websites?
Mixed content occurs when an encrypted HTTPS page links to or embeds resources using unencrypted HTTP protocols, triggering browser security warnings.
How does this checker protect privacy?
All URL parsing, link extraction, and fragment validation can execute client-side on device with zero user tracking or browsing activity logging.
Is there a limit on how many links I can test?
No, the tool scans all links present in the supplied document or public webpage with zero paywalls.
