根据Google的官方文档,下面是site-targeted广告
How do I target customers?
By keywords.
How are ads priced?
Cost-per-thousand impressions (CPM). You set the price you'd like to pay for each 1000 impressions the ad receives. Clicks don't matter -- you are charged whenever the ad is shown to a user.
What types of ads are supported?
Expanded text ads and image ads.
对于Keyword-Targeted,就是内容定位的广告
How do I target customers?
By websites
How are ads priced?
Cost-per-click (CPC). You set the price you'd like to pay each time a user clicks on your ad. You are charged only when a user clicks.
What types of ads are supported?
Text ads, expanded text ads, and image ads.
从这里面我们可以看出,网站定位广告是基于展示的,点击没有收入。形式为图片广告,或者是扩展文字广告,就是一个广告撑满整个广告的。
而内容定位广告,是基于关键词的,是点击才有收入的。形式为普通文字,扩展文字以及图片广告。
(上面的解释是基于英文文档,个别词语的翻译可能同Google的中文文档不同。)
