Is Your Ad Budget Going to Bots? The Hidden Problem With Digital Ads

You set up a Facebook ad campaign. The dashboard shows 10,000 impressions. You feel good about the reach. But here's what the dashboard doesn't tell you: up to half of those "impressions" might not be human.

This isn't conspiracy theory. It's the current state of digital advertising.

The Numbers Are Worse Than You Think

A 2025 report from Imperva found that automated traffic exceeded human traffic for the first time: 51% of all web activity in 2024 was bots. Not helpful bots like search crawlers. Bad bots designed to inflate metrics, commit click fraud, and drain advertising budgets.

The financial damage is staggering:

Problem	Scale
Wasted on bot traffic (2024)	£190 billion
Programmatic ads that may be bots	Up to 50%
Projected ad fraud cost by 2028	£137 billion

"For the first time in a decade, automated traffic surpassed human activity, accounting for 51% of all web traffic in 2024." — 2025 Imperva Bad Bot Report

When you're paying per thousand impressions, nobody in the ad platform's incentive structure benefits from telling you that 500 of those thousand are bots.

What This Means for Your Business

If you're a small business running digital ads, you're playing a rigged game:

The click fraud problem: Competitors can click your ads to drain your budget. Bot farms click ads to earn commissions. You pay for every click, real or fake.

The impression inflation problem: Platforms profit from high impression counts regardless of whether humans see them. More "reach" looks better on your dashboard, even if the reach is fake.

The attribution problem: When half the traffic is bots, your analytics become unreliable. That "successful" campaign might have converted one real person and a thousand scripts.

This hits small businesses hardest. Enterprise advertisers have fraud detection teams and the budget to absorb waste. A local café spending £500/month on Facebook ads doesn't have those resources.

Why Physical Advertising Is Different

Here's something counterintuitive: the oldest advertising medium might be the most fraud-proof.

When someone walks past a billboard, you know three things with certainty:

1. A human saw it
2. They saw it at a specific location
3. They saw it at a specific time

No bot farms. No click fraud. No inflated impressions. The medium is inherently verified because the medium is physical.

"When you book an OOH campaign, you know when and where it will appear and that you'll have an audience — no ad blockers, fast-forwarding, bots, or fake clicks." — Out of Home Advertising Association

The attention metrics back this up:

• 12 seconds average eyes-on attention for billboard ads
• 5.9x memorability advantage over digital
• 97% of UK adults reached weekly by out-of-home advertising

Digital advertising optimises for impressions. Billboards deliver actual human attention — the thing impressions were supposed to measure.

The Big Companies Already Know This

Here's the irony: tech companies are fleeing digital ads for physical billboards.

Apple, Amazon, and Google — companies that built their businesses on digital advertising — are now major billboard spenders. 25% of the top 100 billboard advertisers are tech or direct-to-consumer brands.

They understand better than anyone: when your competitors can inflate metrics with bot traffic, verified human attention becomes premium.

Out-of-home advertising revenue hit £7.2 billion in the US in 2024, the highest ever. That's 16 straight quarters of growth. Digital billboards are growing even faster.

What Should You Do?

If you're a small business:

1. Question your metrics. That impressive reach number might include significant bot traffic. Look at actual conversions, not impressions.

2. Diversify your channels. Don't put all your budget into platforms where fraud is rampant. Test channels with inherent verification.

3. Consider local physical advertising. A billboard near your shop reaches real humans in your actual catchment area. No bots. No fraud. Just eyeballs.

4. Start small and measure. You don't need a £5,000 campaign to test billboard advertising. Platforms now let you book a single screen for a single day.

The digital advertising model assumed human attention. That assumption is breaking. The businesses that adapt early will have an advantage.

The web's advertising model was built on human attention converted to tracked impressions. In 2026, you can't reliably distinguish humans from machines online. The physical world still can.
