Ad hijacking is a silent budget killer in paid search. If you aren’t actively monitoring your brand terms, unauthorized affiliates and fraudsters could be stealing your traffic, inflating your costs, and damaging your hard-earned reputation.

To protect your brand in today’s competitive landscape, you need more than manual checks – you need instant detection and automated enforcement powered by Adthena’s Ad Hijacking Detection.

What is affiliate and Ad Hijacking?

Affiliate hijacking occurs when bad actors intercept traffic intended for your brand. By redirecting users through unauthorized channels, these fraudsters capture commissions they didn’t earn on sales that would have happened anyway.

In many cases, they pose as your brand by running ads that look identical to yours, using your display URL to trick both the user and the search engine. This is a direct violation of brand protection standards and a primary cause of wasted ad spend.

The 4 costly impacts of Ad Hijackers

Ad hijacking isn’t just a nuisance; it has a direct impact on your bottom line:

  1. Inflated CPCs: Hijackers bid on your brand terms, forcing you into unnecessary brand bidding wars that hike up your costs.
  2. Stolen commissions: You end up paying affiliates for sales they hijacked rather than delivered.
  3. Damaged reputation: Fraudsters impersonate your brand with messaging and offers you cannot control or verify.
  4. Wasted resources: Tracking these players manually through spreadsheets and manual reporting is a massive drain on your team’s time.
