Unlike manually checking for content, comparing the tld of a final destination URL (at ad or keyword level) is the same as that of the ads is ideally suited for an automated script so no further labor should be required no matter what kind of URLs were used.

Except that each time you test the URL you will skew the data recorded by the 3rd party tracking system (it's not really an ad click).
