Invalid Traffic and the Travel Sector: Why Click Fraud Spikes During Holiday Peaks

Holiday Travel: A Goldmine for Fraudsters

Every Q4, the travel industry hits its second-biggest peak after summer. Families book flights for Thanksgiving, Christmas Eve trains, hotels for seasonal getaways, and New Year’s Eve breaks. For travel operators, this is a lucrative period where limited-time offers (LTOs), coupons, and loyalty programmes fuel demand.

But it’s not just travellers lining up. Ad fraudsters know exactly how much money is at stake, and invalid traffic (IVT) quietly drains a significant share of this seasonal spend. Without click fraud protection, travel vendors risk throwing budgets at fake users instead of genuine bookings.

Why the Travel Industry is a Hotspot for Click Fraud

Research shows that bots account for up to 80% of invalid traffic in travel, far above the 15–30% average seen across most industries. This scale of fraudulent activity makes travel one of the most at-risk verticals for wasted ad spend.

Key reasons travel ads attract fraudsters:
‍

• Third-party online travel agencies (OTAs): Many scrape airline and hotel data, reselling it with or without authorisation. This creates uncontrolled and unmonitored traffic sources.
• High-value loyalty programmes: Fraudsters exploit point systems, discounts, and vouchers, draining promotions before genuine customers can redeem them.
• App-driven competition: Operators aggressively push app installs to secure long-term users. Without click fraud prevention, this exposes them to misattribution and low-quality traffic.
• Expensive PPC keywords: Airfare and destination searches carry some of the costliest keywords. Fraudsters target them knowing each wasted click drains budgets fast.

“Where there is money to be made, there will be fraudsters. The online travel market is hugely competitive, with big budgets pouring into PPC and programmatic. Without protection, those channels are rife with ad fraud.” – Mathew Ratty, CEO of TrafficGuard.

The App Problem: How Mobile Fraud Spirals Out of Control

Mobile apps are now central to the travel booking journey. Vendors rely on Google UAC, social ads, and ad networks to drive installs and repeat engagement. But with every additional channel comes increased risk.

• More channels mean more entry points for invalid traffic.
• More fraud means worse outcomes and distorted attribution.
• Distorted attribution pushes spend towards fraudulent sources.

This cycle quickly compounds. At peak holiday times, IVT levels in app campaigns can reach up to 50% of all traffic, an enormous risk when budgets are at their highest.

‍

‍How Travel Vendors Can Prevent Click Fraud

The risk is real, but it’s not inevitable. By adopting the right strategies, operators can protect their campaigns and make sure ad spend drives real bookings rather than bots.

Golden Rule One: Scale Smart, Don’t Retreat

High budgets attract fraud, but cutting spend isn’t the solution. Instead, invest confidently with click fraud prevention software in place. By blocking bots at the source, advertisers can continue scaling acquisition campaigns without fear.

Golden Rule Two: Don’t Rely Solely on MMPs

Mobile Measurement Partners (MMPs) are critical for attribution, but they are not fraud prevention tools. Most only analyse data after installs, missing fraudulent clicks and impressions. This leaves travel vendors vulnerable to distorted attribution and wasted budgets. Pair MMPs with real-time click fraud protection to ensure every install comes from a genuine user.

Golden Rule Three: Protect Every Channel in Real Time

From Google Search to Meta ads and affiliate campaigns, fraudsters don’t discriminate. Operators need prevention that works across all channels, not just post-campaign detection. TrafficGuard

prevents invalid traffic across paid search, social, mobile apps, and affiliate, giving travel vendors full confidence in their acquisition data.

Staying Ahead of Fraud This Holiday Season

Invalid traffic doesn’t just waste ad spend, it corrupts the data marketers depend on for optimisation. With half of all app installs or clicks at risk of fraud during peak travel periods, ignoring the problem means starting every campaign at a disadvantage.

By implementing click fraud prevention software, travel vendors can:

• Protect holiday campaign budgets from bots and fake clicks
• Ensure loyalty programmes and promotions reach genuine travellers
• Unlock clean, accurate data to guide smarter bidding and optimisation
• Scale campaigns with confidence instead of caution

‍

Conclusion

The holiday season will always be hectic, but your ad spend shouldn’t be wasted on fake clicks. With TrafficGuard’s click fraud protection, travel operators can keep budgets focused on real travellers, secure clean acquisition data, and drive bookings that count.

FAQs on Click Fraud in the Travel Industry

1. How can travel operators distinguish between legitimate OTA traffic and scraping bots?

Legitimate online travel agencies (OTAs) typically send steady, consistent referral traffic and complete conversions within normal booking windows. Malicious scraping traffic shows patterns like high click volume with low conversions, unusual geographies, or abnormal user agents. Using click fraud prevention software helps identify and block these invalid clicks without cutting off genuine partners.

2. How does invalid traffic affect attribution in travel app campaigns?

Invalid traffic can inflate installs and misattribute conversions to the wrong channels. This happens when MMPs only detect fraud after the install, missing fraudulent clicks. Marketers should monitor click-to-install times, abnormal install spikes, and duplicate device IDs. Adding real-time click fraud protection ensures installs are tied to genuine users, not bots.

3. What are the benchmarks for click fraud in travel advertising?

Travel is one of the hardest-hit industries. Research shows bots make up to 80% of invalid traffic in travel, compared with 15–30% across most sectors. In mobile app campaigns, invalid traffic can reach as high as 50%. For PPC and Meta ads, operators should expect invalid traffic in the 20–40% range without dedicated click fraud prevention.

4. How can travel brands prevent loyalty programme fraud in digital campaigns?

Loyalty fraud often appears after acquisition, but patterns can be traced back to ad sources. Watch for unusual redemption rates, bulk sign-ups from the same IP range, or sudden spikes in coupon usage tied to specific campaigns. With click fraud protection in place, marketers can block fraudulent clicks at the entry point before fake users exploit loyalty rewards.
