流量验证
流量验证用于识别非法、意外或计算机生成的无效点击。我们会从您的点击指标中删除无效点击，因而不会针对这些点击向您收费。
我们使用点击验证软件来确定点击是否无效。我们的软件会审核您的广告获得的所有点击，并分析每次点击以识别无效点击的模式。
点击无效的原因包括：
不寻常的点击模式
被确定为机器生成的点击
重复的点击
大多数无效点击都会在一天内删除。某些流量验证可能需要长达三天时间才能显示在广告活动管理和报告的销售指标中。因此，最近三天的指标可能会不时波动。
如果我们在初次报告之后发现无效点击，您的点击和支出数据将在广告活动管理中重新列报，并在您今后运行的商品推广活动报告中重新列报。您只需为有效点击付费。

Traffic validation
Traffic validation identifies invalid clicks that are illegitimate, accidental, or machine generated. We remove invalid clicks from your click metrics so you will not be charged for them.
We use click-validation software to determine if a click is invalid. Our software reviews all clicks received on your ads, and each click is analyzed to identify patterns of invalid clicks.
Reasons clicks may be invalidated include:
Unusual click patterns
Clicks identified as being machine generated
Duplicated clicks
Most invalid clicks are removed within a day. Some traffic validation can take up to three days to show up in the sales metrics in Campaign Manager and in reports. As a result, metrics from the most recent three days might fluctuate from time to time.
If we identify invalid clicks after the initial reporting, your click and spend data will be restated in Campaign Manager and in future Sponsored Products campaign reports that you run. You will only be charged for valid clicks.
