How Google Manages Click Fraud 130

Posted by ScuttleMonkey from the making-advertisers-warm-and-happy dept.
Finin writes "In February 2005, Google was sued by Lane's Gifts & Collectibles in a class-action lawsuit over click fraud. The company alleged that Google had been improperly billing for pay-per-click ads that were not viewed by legitimate potential customers. As part of a settlement earlier this year, Google agreed to have an independent expert examine their click fraud detection methods, policies, and procedures and make a determination of whether or not they were reasonable measures to protect advertisers. The report of the expert, NYU Information Systems Professor Alexander Tuzhilin (a Professor of Information Systems at NYU), is now available." Update 07/26/2006 at 12:52 GMT by SM: Fixed the link to Tuzhilin's report.

      • While it's true that revealing too many information is an information security problem, they are in a position that most advertisers believe that Google AdWords has more invalid clicks than other competitors. They have to prove (or at least, show) something to keep customers.
        • While I understand that the customers want info about invalid clicks, in this case I think they are shooting themselves in the foot. Security through secrecy has always been a hot topic, but in some cases it definitely has an advantage. Customers will not be pleased if click fraud increases as a result of this, and Google will possibly have to move faster and with more resources to shore up their fraud detection (not too bad for customers but could be bad for Google with the bad PR, etc).

      • Simple solution... Delay the data by a random time. At one attempt per minute you could find 'working' fraud methods pretty easily, but if you had to wait 4 days between each attempt then it becomes infeasible.
        • While that possibility did occur to me, there is also these issues:
          Giving the customer recent data, preferably not more than 48 hours old. Most people will expect near real time statistics from Google on this one.
          Using multiple accounts to test many methods, thus allowing many attacks to be checked while making any delay between attack/statistics less of an issue.

      Google make pots of money because AdWords does result in a good return on investment relative to other forms of advertising.

      Consider this. Imagine a fictional company that spends $10,000/month with Google on advertising, and is completely happy with the service because it results in lots of leads and sales. So it is actually profitable to spend this money. There are many companies in exactly this situation. Does it matter if 90% of clicks are fraudulent (which is probably not going to happen unless you are being deliberately targetted by a competitor)? If you are still getting a great ROI then no it doesn't matter. The invalid clicks are just noise.

      Google does produce something valuable if not physical - it produces a ton of people viewing websites who then go onto buy things. Same as any form of advertising. Except the relevance of AdWords makes it more valuable than most.

      • Yes it matters, because if 90% of the clicks are fraud, then you are spending 90% too much money on advertising. Just because a company is profitable using AdWords doesn't mean that they couldn't be more profitable if the click fraud was removed. Also, the cost of PPC advertising is going up. So while you may be profitable now, in a year, you won't be unless the click fraud can be removed.

        • Yes it matters, because if 90% of the clicks are fraud, then you are spending 90% too much money on advertising.

          Wrong. Google sells ads by auction. So, the price is determined by what people are willing to pay for it. If 90% of clicks turned out to be fraudulent and were filtered out, then people would just be paying 10 times as much for the remaining 10%.

          The real problem is when click fraud is targetted at individuals, who end up getting 100% screwed.

You spent $20 of your budget on Google Adwords, 25% of which went to click fraud.

        That objection can be solved if you add the concept of 'noise' to Google's reported numbers, and I'd say most people already do that.. at least to some degree.

        I don't think many people expect every adwords click to result in a sale for the advertiser. Instead, people just check to see whether there's a correlation between 'more adwords clicks' and 'more sales'. If 100 adwords clicks produce 30 additional sales, you can say that the adwords are 30% effective. Then it's up to you to decide whether those 30 additional sales are worth the cost of those 100 clicks. If so, you can write 70% of their adwords fee off as a cost of doing business. If not, you can close your adwords account, or lower the amount you're willing to pay per click.

        If Google was padding its numbers, people would see lower return rates from their adwords accounts. Those people would then be less willing to pay for the service. They wouldn't expand their accounts to cover other words.

        In other words, there's already a feedback mechanism that punishes Google for any loss of efficiency in its adwords program, and rewards Google for providing the best results it can.

    • Latest post aside, even if advertisers don't get driver data etc... they still expect the ad to be on the billboard. Billboard companies charge by space with an adjustment for the quality of the space. If they misrepresent the space, i.e. you buy 50 spaces and get 10 that is simple fraud.

          • Sorry to be nitpicky and jump into this discussion, but none of the behvior you're talking about re: clicks is illegal. It goes against the Google terms of service (which is why they try to stop it) and it means that Google misrepresents click-through rate to its customers if they can't account for it; the latter constitutes fraud.

            In other words, it's not illegal for you to build an ad-block that does what you describe. It's illegal for Google to refer to the pageloads that result as a legitimate click-th
            • Illegal and against the Terms of Service are two totally different things.

              Here's a more solid example if you're unclear:

              People can (And do) sell AOL screennames for quite a bit of money. It's against the terms of service and they'll kill your account if they catch you. It is not illegal though.
            • It's in fact inaccurate to speak of any legal/illegal distinction. This is simply about breaching a contract, and breach of contract is not illegal. You can be sued on it for sure, but it's not illegal in the sense that it is prohibited by law. You just have to pay damages resulting from your breach. (And there are even legal scholars who argue that sometimes you *should* breach; it's called efficient breach.)

      This is impossible, since fraudulent clicks can be in every aspect equal to true clicks. First there is no clear definition on what is a fraudulent click, google and the target site only see an ip, a user-agent among some other http fields and a timestamp of the time that several things were loaded and clicked.

      One can argue that with some statistics one can find a site that is using automated clicking by using a network of infected computers. This would show as a unusual amout of clicking, but if the bad gu

    Just a comment on their detection process. As a publisher who was terminated (and appeal denied) I do not believe in their process. I have a very active dinosaur website (approaches 1 million hits per month in school year -- probably lots of kids/teachers). it went well for one year then without notice (must be their autormated removal process) I was terminated for me or someother person associated with me generating what they classified as invalid clicks. Well I can state clearly i did not generate one invalid click, and I am only person doing website. So some other process was generating invalid clicks in their checking process. I am not sure what, whether with lots of activity I was getting those repeat 2 clicks that they filter out as invalid? Was there some spider clicking these (a competitor as I have heard about). All I maintain as a publisher I was terminated for nothing I did but was unfaily accused of doing invalid things. Does not make me very favorable to Google and their monolithic, unfair giant system. And I am happy to tell any one who asks what I think of their crummy system!!! Russ Jacobson Illinois State Geological Survey Champaign, IL
    • It sounds like you got a truly horrible treatment. An intersting question is whether the adword business model works at all given that fraudulent clicks can be generated for two opposite purposes and there does not seem to be a fair system to separate them: 1. Increasing website revenue, 2. Kill competitor - very efficient since there are few other advertising alternatives out there for small publishers.
    • I've heard about similar cases, and I think it sucks. That's why the lawsuit against Google bothers me so much. If their current fraud-detection process does not catch "enough" fraud, imagine how ridiculously strict it will have to become to accomplish such a difficult feat.

      I've wondered what would happen if I used Ad-words on my blog and a person in my family happened to click on an interesting ad. Given it's a low-volume blog I'm sure that Google would be able to correlate the IP addresses, so I imagine s
    • I too have experienced first hand the process of being terminated from google as a result of invalid page clicks. Any attempt to gain an explanation as to how the invalid clicks occured is met with standard form letters telling you that you can appeal but Google reserves the right to terminate anyone at anytime. It is really quite stupid as you have the option of appealing, but unless you know why you have been banned, as in where the clicks have occured, you have no hope of explaining any invalid clicks.

    The last link is actually very good, and an easy read. Surprising for a legal document. It is "Googles Omnibus Response to Objections". I suggest giving it a read (PDF) http://googleblog.blogspot.com/pdf/objections_resp onse.pdf [blogspot.com]

    It is basically a response to the objections of a grand total of 51 people in "the class". An incredibly small number of objections.

    From the document:
    "The assertion that Google has done nothing wrong was echoed by advertisers that opted out of the settlement."
    "Unlike Retailers, Pay per click advertisers can limit the money risked for each click and for each day...Businesses should treat pay-per-click advertising like any other advertising...If it's costing more to advertise than your resulting profit, STOP ADVERTISING."

    And, regarding the "click fraud detection", there is only a small portion of this document that mentions the review process by Dr. Tuzhilin. It does mention that the click fraud detection methods by Google were confirmed to be reasonable.

    And finally, it was interesting to see read the jabs taken at the lawyers who brought the class action lawsuit to begin with...and the copy-cat cases from California, obviously a bunch of ambulance chasers.

He subscibed to Google's adsense in order to generate some revenue. When a story about a filesharing lawsuit broke in the lamescream news, an article in p2pnet was referenced. This article generate a huge number of visits and therefore a much larger than usual number of adsense clicks. Rather than pay what was owed to Jon, Google accused Jon of click fraud and even showed information implying his guilt. Google continues to ignore Jon's request for information relating to this accusation and refuses to communicate with him to clear things up.

    You can read about it at http://www.p2pnet.net/story/9086 [p2pnet.net] . This has happened not only to Jon Newton but also to many other small website owners.
