点击广告
Advertisers can also precisely measure the response to an advertisement through the number of times an AD is clicked on, which is difficult to do with traditional television, printing and boards.───广告主也可以通过广告点击次数来准确评估人们对广告的反应。
I have actually clicked on a Gmail AD.───而且我也曾确实点击过Gmail中的广告。
The reason is that some visitors clicked on the AD, and then later, during a different session, returned directly to the site through a bookmark.───原因是，一些访问者点击广告，然后再在不同的工作阶段，直接交还该网站通过书签。
