To submit an ad for a specific country, just login to your account and mouse over the Advertise link and select Manage My PTC Ads. Then on the right click the BUY link and purchase the amount of ad credits you want. Once your transaction is completed and your ad credits approved you must come back to this page and where it says Active PTC Ads click the ADD link to add the website that you want to promote.
Once this site has been added and approved by our staff you can then come back to this page again to assign the ad credits you purchased to your ad. This is where you can also elect to target a specific country.
As always if you have any questions on this or anything else please submit a helpdesk ticket.
