The hidden risks of Google’s automated advertising
When it comes to online advertising, Google is often the go-to platform for businesses seeking to maximise their reach, traffic and conversions. However, there’s a growing concern over the quality of traffic generated by Google’s advertising inventory outside of Search ads, which are built upon the premise of user intent.
The rise of bot traffic and over-reliance on automation, particularly with Google’s Performance Max (PMax) campaigns, are issues that demand closer scrutiny.
The surge of bot traffic
Have you ever checked your website analytics and been thrilled by a sudden spike in traffic? Well, here’s a sobering fact: almost half of that traffic might not be real. According to research from Akamai, bots make up 42% of overall web traffic, with a staggering 65% of these bots being classified as “malicious”.
These bots aren’t just benign scripts; they are designed to mimic human behaviour, generate fake clicks, impressions, and conversions, thereby syphoning off advertising budgets.
Financial impact of bots
Bots are created for financial gain. Fraudsters use them to exploit pay-per-click and pay-per-impression advertising models, pocketing profits from advertisers who believe they are reaching real customers. Beyond financial theft, bots can scrape data, gather competitive intelligence, and perform actions on your site that appear genuine, such as filling out forms or clicking through pages, which we’ll explore further.
Skewed metrics and misguided strategies
In performance marketing, every interaction is supposed to count. However, when bots infiltrate your traffic, they distort your metrics, making it difficult to assess the true effectiveness of your campaigns.
You might be celebrating an increase in clicks or conversions, but if a significant portion of that activity is fake, you’re not getting the accurate insights needed to optimise your strategy. Instead, you’re wasting money on campaigns that are engaging more bots than actual customers, skewing your ROI and clouding your decision-making process.
Performance Max: A closer look
Google’s Performance Max campaigns are designed to leverage AI for automating ad placements across all Google properties. While this sounds efficient, it also opens the door to significant risks. Dr. Augustine Fou, in his detailed analysis, found that approximately 86% of traffic from PMax campaigns were bots. Using a combination of JavaScript tags and UTM parameter reviews, Fou tracked key metrics like referrer URLs, HTTP User Agents, and hardware specifications to identify fraudulent activity.
The automation trap
The primary issue with PMax is over-automation. By handing over control to “AI”, advertisers risk losing transparency and oversight. Google’s algorithms, while sophisticated, can inadvertently, or seemingly even deliberately, optimise for fraudulent traffic because they rely on signals that bots can easily manipulate. This leads to budget being allocated to low-quality, non-human traffic sources.
Achieving transparency and control
To counter these issues, advertisers need to take proactive steps:
Audit your traffic: Regularly audit the traffic generated from PMax, Display, and Programmatic campaigns. Look for unusual patterns, such as spikes in traffic from unexpected regions or high bounce rates that could indicate bot activity.
Invest in bot detection: Implement robust bot detection software. Tools like FouAnalytics can provide deeper insights into traffic quality by analysing detailed parameters and identifying suspicious patterns.
Manual oversight: Don’t rely solely on automated solutions. Manual oversight and regular reviews of campaign performance are essential. Understand where your ads are being placed and who is engaging with them.

Moving forward with caution
As digital advertising evolves, the importance of transparency and vigilance cannot be overstated. While Google’s advertising platforms offer extensive reach, the quality of traffic, especially from automated campaigns like PMax, requires careful monitoring.
By taking a proactive approach and utilising advanced tools, advertisers can protect their investments, ensure genuine engagement, and optimise their performance marketing strategies effectively.
In conclusion, while automation in advertising can offer significant efficiencies, it also presents new challenges. The rise of bot traffic and the risks associated with over-automated solutions like Google’s Performance Max necessitate a balanced approach that combines technology with human oversight to achieve the best results.
