A Google Ads targeting tactic that cut invalid clicks by 50%

Advertisers are estimated to suffer $172 billion a twelvemonth owed to advertisement fraud by 2028. 

The problem is particularly communal successful industries pinch precocious title and CPCs. One of our clients operated successful conscionable specified an industry, wherever precocious invalid click activity was tanking run performance.

By adjusting Google Ads targeting, we reduced invalid-click activity by 50% and restored profitable performance.

Case study: How we trim invalid clicks by 50%

Our customer sold book editing and ghostwriting services. The hunt position that triggered our ads were applicable and precocious intent. Yet the postulation wasn’t converting astatine anyplace adjacent a profitable rate.

We quickly identified signs of click fraud, including:

• Google reporting a 60% to 80% invalid click rate.
• Microsoft Clarity recordings showing bot-like behaviour from Google Ads traffic.
• 80%+ click-through rates crossed galore hunt terms, pinch immoderate exceeding 100%.
• Far less sessions successful GA4 and different analytics devices than the number of clicks Google Ads reported.

We tried third-party click fraud devices but saw nary measurable capacity improvement.

Next, we revenge an investigation pinch Google. Google agreed location was suspicious activity but said it had caught it each and hadn’t charged for it.

We were assured Google wasn’t filtering retired each the invalid activity, truthful we took matters into our ain hands.

We added 540 Google-defined audiences group to “Targeting” to our Google Search campaigns.

The invalid click complaint instantly dropped by 50%, and the conversion complaint accrued to profitable levels.

We’ll explicate why we tested this attack and why we judge it worked.

First, let’s reappraisal what invalid clicks are and the modular ways advertisers combat them.

What click fraud and ‘invalid clicks’ really are

Google defines invalid clicks as: 

• “Clicks connected ads that aren’t the consequence of genuine personification interest, including intentionally fraudulent postulation and accidental aliases copy clicks.”

This includes actual fraud from competitors clicking your ads, arsenic good arsenic accidental double-taps.

Google doesn’t complaint advertisers for clicks it deems invalid. Google besides credits advertisers for clicks it initially charged for if it later determines those clicks were invalid.

Why the accustomed defenses sometimes autumn short

Google’s discovery strategy catches a batch of invalid click activity, but arsenic our illustration shows, it’s not perfect.

Because of this, an full manufacture of third-party devices tries to artifact fraud-prone IP addresses earlier they costs you.

Unfortunately, fraudsters cognize really these devices activity and often rhythm done IP addresses utilizing VPNs to enactment 1 measurement up of the monitoring software.

A instrumentality whitethorn place suspicious activity from an IP reside and artifact that reside from seeing Google ads successful the future. But if the fraudster uses a caller IP reside each time, blocking erstwhile addresses does nothing.

These devices are besides constricted because Google allows a maximum of 500 IP reside exclusions per campaign.

The tactic: Add audiences group to ‘Targeting’

We thought astir what mightiness separate fraudulent postulation from morganatic traffic. What came to mind was Google’s predefined audiences. Google creates hundreds of audiences based connected personification demographics, hunt behavior, and browsing behavior.

For example, if you’re researching backstage pitchy companies and Rolex watches, Google mightiness categorize you arsenic a luxury shopper and spot you successful that audience.

We hypothesized that fraudsters cycling done IP addresses aren’t ever taking the clip to build normal-looking online profiles that fresh into Google’s predefined audiences.

So we added astir of the disposable audiences to our Search campaigns.

We didn’t limit ourselves to audiences specifically related to the group we were targeting. Instead, we utilized the audiences arsenic a select for users who fresh Google’s assemblage signals.

Important: We chose the mounting “Targeting,” not “Observation.”

When you take Targeting, Google limits your ads to group who trigger your keywords and beryllium to the selected audiences.

If you take Observation, Google reports really users successful those audiences prosecute pinch your ads compared pinch group extracurricular those audiences, but it tin still show your ads to anyone who triggers your keywords.

We only urge this for accounts pinch precocious invalid click rates.

There are imaginable downsides to this approach, specified arsenic unintentionally blocking morganatic users who don’t fresh wrong Google’s pre-defined audiences.

How to trial this successful your ain account

In a Search campaign, prime Audiences > Edit assemblage segments > Targeting > Browse. Select the audiences you want to adhd and click Save.
