5 Best Ad Fraud Detection and Prevention Tools for Digital Advertising (Update 2021)
Over the last few decades, governments and private companies alike have shifted from paper records to a mostly digital environment. While this has improved functionality and allowed these organizations to deliver better services, it has also opened the floodgates of digital fraud and cybercrime as a whole. From financial institutions to government agencies, cybercriminals have successfully targeted dozens of industries and the digital marketing vertical is no exception.

In the marketing context, ad fraud is a deceitful practice that consists of interacting with a digital advert to drain the advertiser’s resources without actually producing results. This umbrella term describes a wide variety of different activities, but all of them have the same goal.
In the early days of ad fraud, deceitful parties used rudimentary techniques to extract money from online adverts. Unfortunately, these fraudulent parties have developed new approaches that make it much difficult to detect unwanted interactions that drain resources without generating profits in return.
At lemonads, we see ad fraud as one of the biggest threats to the entire digital marketing industry. We understand the importance of creating a safe ecosystem for publishers, advertisers, ad networks, affiliate networks, and other members. But, the only way to successfully combat ad fraud is to present a united front and ensure that all stakeholders are taking the steps to secure their marketing resources.
Over the years, our team has developed a robust in-house solution that minimizes instances of ad fraud in our network, so we have a good idea of the features you need to implement to stay safe.
Below, we’ve put together a list of the best anti-fraud tools for digital advertising in 2021 to help advertisers, publishers, and all other stakeholders protect their marketing resources.
Ad Fraud and the Digital Advertising Industry
Before going over the best anti-fraud tools for digital marketing, it’s important to understand the impact of this type of cybercrime.
It’s estimated that the digital advertising industry lost more than $42 billion in 2019 alone and that number can reach a staggering $100 billion by 2023 if the problem is not addressed properly.

This could potentially cause irreparable damage to the digital marketing industry, so we need to proactively safeguard the areas that are most vulnerable to fraudulent activities.
What Steps Can Stakeholders Take to Minimize Ad Fraud?
Some forms of ad fraud are almost as old as the internet itself, so you need to invest part of your resources into protecting your marketing dollars. However, one of the reasons why these deceitful practices are still an issue today is because they are difficult to detect. There are also many different types of ad fraud that you need to look out for, so it’s normal to feel overwhelmed by the idea of protecting your resources from all of these external threats.
Instead of taking on the bulk of the work manually, your best bet is to find a suitable anti-fraud tool for your specific case. There is no “silver bullet” solution that works in all instances, so you need to examine the different options you have available and find the platform that will help minimize advertising fraud in your marketing activities.
