Key Takeaway: The targeting infrastructure that made conquest campaigns viable is gone. You're not paying more because competitor customers are harder to convert. You're paying more because you can't tell who they are anymore.
Run a brand campaign and a conquest campaign side by side. Same creative quality, same offer structure, same landing page. The conquest campaign will cost 30-50% more per acquisition.
This isn't because competitor customers are inherently harder to convert. Someone actively dissatisfied with a competitor is often an easier sell than a cold prospect. They know the category, they have the budget, and something's already broken in their current situation.
The cost gap comes from somewhere else entirely: you can't reliably identify who's actually a competitor customer anymore.
When you bid on competitor keywords, you're reaching everyone who searches that term. Current customers logging in. Job seekers researching the company. Journalists writing articles. Investors doing due diligence. Actual switchable prospects are a fraction of your impressions.
The same problem hits display and social conquest campaigns. Without third-party cookies, building audiences of "people who use competitor X" has become guesswork. Lookalike models trained on thin data. Contextual placements near competitor content. Interest-based targeting that catches anyone who's read about the category.
You're casting a wide net and hoping competitor customers are somewhere in there. That hope is expensive.
Break down the math on a typical conquest campaign:
CPCs on competitor keywords run 2-4x higher than brand terms. You're competing against the competitor's own brand bidding, plus every other company trying to poach their customers. The auction is crowded.
Conversion rates run 20-40% lower. Not because the prospects are worse, but because most of the people you're reaching aren't actually prospects. They're noise that looks like signal.
Put those together and your cost per acquisition inflates by 30-50% or more. You're paying a premium for targeting that doesn't work, then paying again when the traffic doesn't convert.
This wasn't always the case. Third-party cookies gave marketers imperfect but useful signal on competitive audiences.
You could retarget people who'd visited competitor websites. You could build lookalikes seeded with known competitor users. You could layer behavioral data to approximate "people who use products like competitor X."
None of it was perfect. Match rates were never 100%, and privacy concerns were valid. But the infrastructure existed to at least narrow the target.
That infrastructure is gone. Safari and Firefox blocked third-party cookies years ago. Chrome is following. Apple's ATT collapsed mobile tracking. The signals conquest campaigns relied on have degraded or disappeared.
What's left is mostly inference. Probabilistic guessing dressed up in platform jargon.
There's a different way to think about this problem.
Instead of trying to identify competitor customers through targeting, let them identify themselves. Create an offer specifically for verified competitor users. Someone claims they want the switching bonus? They prove they have an active competitor account.
User logs in to their competitor account. Verification confirms they're a customer. Offer unlocks.
The economics shift immediately. Every dollar of switching incentive goes to an actual competitor customer. No waste on researchers, job seekers, or journalists who happened to search the competitor name.
Conversion rates look different too. You're not hoping qualified prospects are in your audience. You've verified they are before making the offer.
The 50% premium on conquest campaigns isn't a law of nature. It's a symptom of broken targeting.
When you can't tell who's a competitor customer, you pay to reach everyone and hope. When you can verify it, you pay only for the real thing.
Same strategy. Different execution. Very different unit economics.
The competitor's customers are still valuable targets. The question is whether you're going to keep paying the targeting tax or find a way around it.
