What is ad fraud?

Ad fraud is the deliberate manipulation or generation of fake advertising activity to deceive advertisers and improperly generate revenue. It can involve fake clicks, impressions, conversions, installs, leads, or other interactions that make advertising performance appear better than it actually is.

Common Types of Ad Fraud

• Click fraud: Generating artificial clicks on advertisements without genuine interest.
• Impression fraud: Creating fake or non-human ad impressions to charge advertisers.
• Bot traffic: Using automated programs to imitate real users and interact with ads or websites.
• Fake conversions: Creating fraudulent purchases, leads, registrations, or other conversion events.
• Ad stacking: Placing multiple advertisements on top of one another even though the user can see only one.
• Pixel stuffing: Displaying advertisements in extremely small spaces where users cannot realistically see them.
• Domain spoofing: Misrepresenting the website or app where an advertisement is actually being displayed.
• Click farms: Using groups of people or coordinated systems to generate artificial clicks or engagement.
• Install fraud: Generating fake or manipulated app installations to receive advertising or affiliate payouts.
• Affiliate fraud: Manipulating clicks, leads, or sales to earn illegitimate affiliate commissions.

Why Is Ad Fraud a Problem?

• Wastes advertising budgets
• Distorts campaign performance data
• Reduces the accuracy of attribution
• Makes optimization more difficult
• Can increase CPC, CPA, or customer acquisition costs
• Creates unreliable audience and conversion insights
• Can damage trust between advertisers, agencies, publishers, and platforms

Example

Suppose a company spends ₹1,00,000 on online advertising and receives 20,000 clicks. If a significant portion of those clicks comes from bots rather than genuine potential customers, the advertiser may pay for activity that produces no real business value. This is an example of ad fraud.

In short: Ad fraud is the artificial manipulation of advertising activity to generate illegitimate revenue or make campaign performance appear stronger than it really is, resulting in wasted budgets and unreliable marketing data.
