Geo-targeting allows you to target by country. In the US we also offer region targeting. Region targeting will narrow your reach by a large amount. If you combine them with several other targeting options it may narrow your reach too
much and you will not receive many impressions.
Keyword and Channel:
The system will match your ads to relevant sites on the FullTraffic Network using your keywords or topics, among other factors. Contextually targeted ads offer useful information to readers, and attract an audience interested in your message.
You have the option to display your ad on preferred sites or all sites. Preferred sites have a history of performing better. If you target preferred sites it will narrow your
reach and require more time to deliver the entire campaign.
