in reply to Monitor queries for new finds added to the Google index yesterday

After your line beginning with my $results = $google_search, I recommend adding the following: 
use Data::Dumper::Simple;
print Dumper($results);

That will be a big help in your debugging. (You may need to install Data::Dumper::Simple first.) Also, I recommend you consider using Text::CSV to create your CSV file.

It's all fine and dandy until someone has to look at the code.
