When you start getting clicks.

[montyauto]

You bid one term and you start getting clicks.

How many clicks will you allow that ad to receive before you start looking at how much you are paying per click and how much money you are making in sales?

Sorry to say this montyauto, but that's an Adwords question. Hopefully the mods will see it here and move it into the correct section.

You should get more feedback in that space. ;)
