Restricting Ad Visibility
I am having a client who want to show Ads only to US audience, but by using some free available proxies I am also able to see the Ads in India. Can we block proxy users to see my Ads to avoid invalid click from my competitors..
Re: Restricting Ad Visibility
In order to avoid clicks from other location you can select the Target using physical location: Device-based location signals.
If the advertiser chooses the option "Device-based location signals" then the ads will be shown only in the areas targeted (in your case USA).
This link helps you better understand about the advanced targeting features.
Thanks and Regards,
