Google AdSense: Still Legit in 2022?

According to Google, more than two million people use Google AdSense. As Ads represent the majority of the $257.63 billion revenue Google hit in 2020/2021, it's easy to see that Google AdSense is an integral part of the internet.

Essentially, Google AdSense's business model is easy to understand: they show relevant ads on third-party websites and, when a user clicks on them, the website owner earns money. The advertiser pays Google for the click, and Google pays the website owner a commission.

Easy, right?

Except there's also this "thing" called invalid traffic...

What Is Invalid Traffic?

To answer the question of "how to check invalid clicks in Google AdSense", we should first answer the question "what is invalid traffic". The real answer is a bit more complicated than you might think.

In short, invalid traffic is any click or impression that is not the result of a real person genuinely interested in the ad. This could, for example, be automated bot traffic or traffic from users who are incentivized to click on ads (by motives other than actually buying something.)

The issue with this is that Google Ads are paid by clicks and impressions -- so if a click doesn't come from a real human who's potentially interested in buying your product, it's a wasted click. Which is the driver behind wasted traffic and wasted budget when you're running Google Ads.

Not all invalid traffic is click fraud. Some of the more common causes of invalid traffic include (but are not limited to) the following:

• Clicks generated by publishers on the ads shown on their own sites (so that they can get better commissions)
• Accidental clicks on ads
• Intentional, repeated clicks performed by humans (usually in click farms, with the purpose of click fraud)
• Intentional, repeated clicks performed by bots and botnets with malicious intent 

Invalid traffic can also be generated by humans, but not all of these clicks are click fraud either.

How big is this issue?

Well, according to Imperva more than half of all internet traffic is driven by bots. Arguably, not all of them are bad bots, and even among the bad ones, not all of them are click bots. Our findings last year revealed about 17% of ad traffic is click fraud, which means that if you spend $15,000 every month on Google Ads, about $2,550 is wasted on ad fraud. In one year, that's $30,600 you're not getting back.

And if you think you can just submit a request or file a lawsuit and get your money back, think again. Here's why.

Invalid traffic and click fraud aren't limited to Google AdSense. They happen on virtually any kind of Google Ads campaign. But with Google AdSense, things get a little more complex because publishers are sometimes part of the problem.

In those situations where publishers are part of the problem, things can easily get spiky. On the one hand, Google AdSense publishers lie at the foundation of the entire AdSense ecosystem ' and so, they play a huge part in how Google charges advertisers.'

On the other hand, if publishers drive fake clicks on the AdSense ads they have on their site, it all becomes a game advertisers lose from the get-go. So it's only natural that Google has implemented a series of measures to prevent Invalid Traffic and chastise rogue publishers. 

That being said, it is important to note publishers themselves can become victims of click fraud & invalid traffic. It could be a competing publisher driving false, irrelevant, or even bot-actioned clicks on your site. Or it could be too many readers erratically clicking on ads. Whatever it is, if you are a publisher and you want to make sure you don't get suspended by Google, you will want to check invalid clicks in your Google AdSense account. 

AdSense Click Bombing -- When Villains Become Victims 

Google blocks AdSense accounts if they suspect unusual activity that might drive invalid traffic to the ads published through their program. As Google itself has stated, "Some publishers have had issues with invalid traffic when partnering with low-quality ad networks, search engines, or directory sites in efforts to increase traffic to their site."

And yet, publishers can sometimes become victims of the villainous acts they're accused of. AdSense click bombing is a type of click fraud that's carried out against AdSense publishers. This is done by artificially inflating the number of clicks on ads shown on a publisher's site in an attempt to get them kicked out of the program. 

What's important here is that ad fraudsters don't need to access your AdSense account to bomb your ads. They just need to click on them repeatedly -- either manually (sometimes through click farms) or automatically (through bots and botnets.)

How Does Google Deal with Invalid Traffic?

Google has a few mechanisms in place that help them fight invalid traffic in Google AdSense

• Automatic Filters: Google has a system that checks for clicks coming from unusual IP addresses or from the same IP address multiple times. When these clicks are detected, they're filtered out and aren't counted as billable activity.
• Filtering in real-time: Google also uses real-time filters that stop suspicious clicks from being counted before they even have a chance to appear in your reports.
• Filtering in near real-time: Another system checks clicks for suspicious behavior and filters them out of your reports within a few hours.
• Manual Checks: In cases where unusual activity is detected, but the automatic filters didn't catch it, the activity is sent to Google's specialist team for manual review.
• Research and botnet hunting: A team of engineers and data scientists is dedicated to finding new ways to detect invalid traffic and botnets.
• Blocking suspicious accounts: If any accounts are found to be participating in fraudulent activity, they're blocked.

Are Google's mechanisms against Invalid Traffic helpful?

To some degree, yes. But even so, a lot of fake clicks slip through the cracks. Despite Google's best efforts, advertisers lose billions to ad fraud every year. In 2021, the world lost $61 billion to ad fraud (across multiple digital ad platforms, but consider the fact that Google has the largest market share on this.)

As a publisher, there are some additional things you can do to prevent AdSense bombing. Some of the more common tips of advice include:

• Don't click on your own ads. This one is pretty obvious, but it still needs to be said.
• Don't ask others to click on your ads. Yes, that includes your readership. Even if your intentions are clean, Google might still perceive this as encouraging readers to repeatedly click on ads 
• Monitor your traffic and use click fraud protection software

If you are an advertiser, you can't really go through all of the websites your ads are published on.

But here's what you can do...

Best Solutions to Block Invalid Clicks in Google AdSense 

Clearly, click fraud is an issue.

You can't sue for click fraud.

Google's tactics aren't very effective either (remember the $61 billion lost to ad fraud mentioned above?)

And you don't have access to all the data in your Google Ads account ' nor do you have all the time in the world to manually sift through gazillions of clicks every day. 

The only legit, sane way to fight it is by using click fraud protection software to identify & block click fraud. In doing this, you drive click fraud costs up for botnet and click farm administrators, so they will find it more difficult to actually wreak havoc on your Google Ads.

ClickGUARD does that and more, including: 

• Helping you spot invalid and wasteful traffic (which may or may not be click fraud) 
• Identifying click bot behavior (and helping you block it)
• Generating detailed reports on your ads campaign. 

Whether you are a publisher or an advertiser, getting protected against click fraud is a smart way to make sure your website and/or your ads are clean. Indeed, advertisers tend to carry the heavier burden when it comes to click fraud and wasteful traffic ' but staying protected should be a priority for everyone.'
