How to detect ad fraud with Google analytics?

As the world of digital advertising grows, sophisticated bot fraud technology increases as well. There is an urgent and constant need for publishers to safeguard their accounts from fraudulent traffic. In this post, we’re going to show you how you can detect fraudulent traffic with Google Analytics.

Let’s start with going over the type of ad fraud based on Google’s ad policy guidelines. Google defines fraudulent traffic as follows:

  • The use of bots and deceptive software to simulate user visits or clicks
  • Invalid clicks by publishers to inflate their click-through rate
  • Incentivizing users to click ads on site
  • Intentional ad placement on areas that can be mistakenly clicked

Google filters potential fraudulent traffic, as mentioned above, through automated detection. They manually review suspected violators and deduct earned profits from publisher earnings. It’s the publisher’s primary responsibility to ensure that they abide by Google policies to continuously maintain in good standing with their ad account. This is not only true for Google but all other demand sources as well.

For publishers, it’s been an endless battle as ad fraud attacks can happen to anyone. If not taken seriously, the publisher can potentially lose their business just because someone sent bot traffic their way.

This is where fraud detection technology comes in. There are tons of different paid tools available, like Forensiq, IAS, WhiteOps, Moat, and Traffic Cop. Still, we cannot ignore the fact that they can sometimes be costly, especially for publishers starting.

However, we’ll show you how you can identify ad fraud just by using the free version of Google Analytics. Keep in mind, following this method, you’re not guaranteed 100% results compared to paid ad fraud detection and prevention services, but it’s a great starting point.

Google Analytics has specific metrics that can serve as indicators to detect ad fraud:

#1 – Average Session Duration

The Average Session Duration refers to the average time that a user stays on the site

#2 – Bounce rate

Google defines bounce rate as  “when someone sees only one page or triggers only one event,” Analytics considers this a “bounce.” Your site’s Bounce Rate is the percentage of sessions that are bounces.”

Though, this does not always mean that invalid traffic or ad fraud is going on. Sometimes this means that users leave the page due to less valuable content on the page causing users to look away. Often, it could also be that your site is hard to navigate or because of incorrect tracking code implementation.

#3 – Traffic Channels

Under Acquisition, there’s a great deal of information that can indicate that one of your referral traffic sources is sending bot traffic instead of real users on your site. The bounce rate should show high %, and Average session duration should show minimal time.

#4 – Referral Sources or Source/ Medium

You can drill down further which referral sources are sending suspected fraudulent traffic, or you can make use of the Source/Medium as well.
