"Verification Failed - http://whateverurlwasposted.com/php.html.etc"...

I am getting a lot of these messages. What does this mean, is it normal and is there anyway to reduce the number of failed verifications?

A failed verification is normal. The program tries to find your link but failed and will check later on again in the hope it is a manual review of your link and so its placed by an admin later on.

Excellent! Thanks!
