Click fraud: A good reason to avoid Google's content network

A new study has come out that suggests that the problem with click fraud is much bigger than what Google and Yahoo! are admitting to. This article is an interesting read all the way through, but AdWords advertisers will want to pay especially close attention to the end of the piece:

Click fraud doesn't appear to be a major problem when the ads appear on Google's and Yahoo's respective websites, Milana said. The trouble starts cropping up once Google and Yahoo deliver the ads to other websites that are part of their vast marketing networks. "They just don't know what happens beyond their own firewalls," Milana said of Google and Yahoo.

What does this mean to you? Disable content network distribution of your ads! Surely, there are advertisers who are getting great returns from their ads being displayed on the AdWords content network, but it's not for the feint of heart.

A good practice is to run some tests with content network distribution, monitor the metrics of those tests, then judge your ROI form there. This is not recommended for new AdWords users–get your accounts tuned for performance first, then experiment with more advanced techniques such as this.

Sr VP of Marketing at on click fraud

It's a longer read than the average blog post, but Joe Holcomb's assessment of the current state of click fraud is worth more than a glance. It's interesting to hear the observations of someone who sits on both the advertiser and PPC engine side of the fence.

The solution to click fraud according to Joe?

"The solution to the click fraud problem lies solely on the shoulders of the PPC’s to invent the technologies necessary to stop click fraud from taking place. The pay per click industry is looking awfully dirty lately. How do we clean it up? Force the engines to change their ways. Speak with a louder voice and withhold your ad dollars from the engines that don’t comply. Work with SEMPO, the SMA-NA, and other marketing organizations to bring these issues to the forefront of the industry. Nothing speaks louder than money. Choose not to spend a dime until the engines solve this problem."


Google wins click fraud case

Google has won its suit against Auction Experts, an AdSense partner publisher that Google accused of deliberate click fraud. Google alleged that Auctions Expert hired dozens of people to click on the site's ads, totalling upwards of $50,000 in click revenue. More information from WebProNews.


Click fraud victims need powerful allies

I was just reading an article over at Wired penned by Adam Penenburg about click fraud. What stood out for me was the last paragraph:

"What can a victim of click fraud do? One solution bandied about at the conference seemed simple enough. Contest the charges on your credit card as fraudulent. If enough merchants did it, they could enlist powerful allies: American Express, Visa and MasterCard, who would likely pressure the other search engines to do something about it."

Sounds like a great idea to me! 


Google sued over click fraud

On June 24, Click Defense Inc. filed a lawsuit, which also seeks class action status, against Google claiming that the search engine giant has failed to protect users of its advertising program from click fraud.

As Nathan Weinberg of BlogNewsChannel points out, Click Defense's actions are curious given that they profit from click fraud–without it, they wouldn't have any services to sell. Publicity stunt or the act of a good samaritan looking out for AdWords clients everywhere?

Tracking Clicks and Click Fraud

Tracking your ads' clicks gives you reliable information about how well your campaign is performing. PPC engines include some detailed tracking information in your advertiser's control panel. To capture a maximum amount of data, it is advisable to also install statistical tracking on your website and record your referring URLs.

Most of the time, you'll notice that the number of clicks tracked by yourself is 15% to 30% more than the clicks the PPC engine reports. This is because reputable PPC engines have installed anti-fraud mechanisms that can catch competitors who are repeatedly clicking on your listings and wasting your bid budget. They will count multiple clicks within a timeframe originating from the same computer as only one click through, while your own log will usually register the multiple clicks.

In addition to competitors who will click away your budget, there are actually businesses set up where workers do nothing all day but click on pay-per-click ads placed by their clients' competitors in order to run out an account's budget as quickly as possible. Unfortunately, click fraud is a reality with current PPC technology, and even though the PPC engines attempt to squash it, advertisers must be vigilant in monitoring their campaigns and reporting suspected fraudulent activity.

Related to ad click tracking, AdWords recently unveiled a ROI tracking mechanism that places a small amount of JavaScript code on your lead completion pages (for example, a "success" page that a user arrives at after completing a request form on your site). When a visitor who clicked one of your ads arrives on your completion page, a notification is sent back to your AdWords control panel allowing you to see which clicks were converted into leads.
