Before getting into the click fraud statistics lets take a quick look at what the problem is. What is click fraud anyway?
What is Click Fraud?
Click fraud is one of the first things that you need to be cautious of when running a PPC campaign. Click fraud (also known as PPC fraud or ad fraud) refers to invalid or illegitimate clicks on PPC ads that are generated by bots, scripts, humans, or any other way.
The purpose of this type of fraud is to exhaust the budget of the advertisers or to bring more money for websites that host ads. Google is aware of the issue, but they qualify both fraudulent clicks and unintentional clicks as “click fraud”. Clearly, this is a problem, because unintentional clicks are not necessarily click fraud, and fraudulent clicks are definitely not unintentional in nature.
PPC fraud has existed for years and has its roots in early PPC and advertising networks. Publishers used to click ads on their own websites to earn money and this practice of earning money has transformed into a gigantic industry today.
PPC fraud isn’t new. It has been around since the early days of PPC and advertising networks, when publishers used to click ads on their own websites to drive more revenue. Yet, today, click fraud is a multi-billion dollar problem that needs to be stopped.

Here is an overview of the click fraud statistics for specific industries that shows how it impacts leading markets in the world. A click fraud protection tool is a must in today’s time, and the following numbers show it clearly.
To put numbers on just how big the issue of click fraud is, we dove deep into the data at ClickGUARD and determined that 17% of Google Ads traffic is fraudulent. To calculate how much money some of the highest-spending industries are losing, we looked at how much these industries are spending on digital advertising and applied the Google having revenue share in the ad industry of 28.9% on those numbers. The result was the amount of money each of these selected industries spent on Google Ads.
Here are the results:
The B2B industry spend a whooping $8.68 billion on digital advertising in 2020. If we apply the 28.9% Google revenue share on this number, it means that this industry spent more than $2.5 billion on Google Ads in 2020 With Google having revenue share in the ad industry at 28.9% in 2020, one can determine that the B2B industry spent $2.508 billion on Google Ads.
Furthermore, applying the 17% click fraud rate we determined from our data, all this means that the B2B industry has lost approximately $0.42 billion to fraudulent clicks.
The business services industry in the U.S. spent about $15.64 billion on digital advertising in 2020. Applying the same data points as above, we can determine that the Consumer Services industry spent $4.519 on Google Ads in 2020 – and lost about $0.768 billion to click fraud.
The ecommerce industry spent $18.72 billion on advertising in 2020. With the Google Ads revenue share at 28.9%, that means the eCommerce industry spent $5.41 billion on Google Ads in 2020.
