Re: just signed up how long does it take to start seeing my add
Hi roundpen88 and welcome to the forum. Assuming everything is set up correctly and there is nothing actually preventing your Ads from being shown, they can appear almost immediately. I've certainly seen Ads working within 20 minutes of completing setup.
However, bear in mind that your Ads will almost certainly operate on a restricted basis (shown as "Eligible" as their status), appearing only on Google search alone until they reach "Approved" stage. This change may also only take an hour or so though so it shouldn't be a problem.
