URL checks and common mistakes

The live form has two negative outcomes and one honest holding message. It does not rank link quality beyond that.

Empty field

Submitting with nothing in the box asks you to enter a link. Nothing is sent.

Not an address

The value must be a full http or https URL with a host, such as https://example.com/watch. A bare word, or “www” without a scheme, is rejected.

A valid address while processing is off

If the text is a real URL, the page says download processing is not available and that the link was not sent anywhere. That is not a failure of the video. There is no engine to succeed or fail.
