CPTM广告

CPTM (Cost per Targeted Thousand Impressions)定位用户千次印象费用

　　CPTM (Cost per Targeted Thousand Impressions，定位用户千次印象费用)是指经过定位的用户（如根据人口统计信息定位）的千次印象费用。

　　CPTM与CPM广告的区别在于，CPM是所有用户的印象数，而CPTM只是经过定位的用户的印象数。

The "M" has nothing to do with "mega" or million. It's taken from the Roman numeral for "thousand".
