散人笔记

无效点击一直是google和广告客户头痛的问题，现在Google Adwords推出了无效点击报告功能，想必将更有助于降低无效点击给广告客户带来的损失。不过在维护Adsense发布者的利益方面，Google尚未有什么好的举措，一般都是凭Google单方面的判断来确定无效点击的主动性和被动性。
附1：Dr. Alexander Tuzhilin在报告《The Lane’s Gifts v. Google Report》中所陈述的十种无效点击：
1. individuals deploying automated clicking programs or software applications (called bots) specifically designed to click on ads
2. an individual employing low-cost workers or incentivizing others to click on the advertising links
3. publishers manually clicking on the ads on their pages
4. publishers manipulating web pages in such a way that user interactions with the web site result in inadvertent clicks
5. publishers subscribing to paid traffic websites that artificially bring extra traffic to the site, including extra clicking on the ads
6. advertisers manually clicking on the ads of their competitors
7. publishers being sabotaged by their competitors or other ill-wishers
8. various types of unintentional clicks, such as doubleclicks or customers getting confused and unintentionally clicking on the ad without a malicious intent.
9. technical problems, system implementation errors and coordination activities between Google.com and its affiliates resulting in double-counting errors
10. multiple accounts of AdSense publishers: some AdSense publishers illegally open “new” accounts under different names and using false identities; all the clicks originated from these illegal accounts are considered invalid.
