The Competitive Advertising Playbook: How to Ethically (and Legally) Steal Your Competitor's Best Customers
Why the smartest advertisers don't compete for attention, they intercept it
You know that sinking feeling when a potential customer walks right past your superior product to buy from your inferior competitor? That moment when you think, "If they only knew what we offered, they'd pick us instead."
Every business owner has been there. You've got better features, better service, maybe even better pricing. But somehow, your competitor got there first. They captured the customer's attention at exactly the right moment, while you were stuck shouting into the void with generic ads that nobody really cares about.
Here's what most businesses get wrong about competitive advertising: they think it's about outspending everyone else on broad keywords. But what if I told you there's a way to surgically target people who are already browsing your competitor's website? (And it's completely legal.)
The Competitive Intercept Framework
Think of competitive advertising like fishing. Most businesses cast wide nets in the middle of the ocean, hoping to catch something. But the smart money? They're fishing right where they know the fish are already biting, at their competitor's pond.
I call this the Competitive Intercept Framework, and it operates on three levels of strategic escalation.
The first approach is what I like to call silent targeting. You're going after people who've visited your competitor's website, but you're not mentioning the competitor at all. It's like setting up a lemonade stand right outside the grocery store, you know people are thirsty, you just don't announce why you picked that spot. In Google Ads, you'd create custom audiences based on competitor website behavior. Think Waitrose targeting people who browse Tesco or Sainsbury's websites, but their ads just talk about premium quality without throwing shade.
But what happens when you want to be a little more direct? That's where implied superiority comes in. You highlight your advantages without naming names. Your ads focus on premium features, better quality, extra benefits, all the things that subtly suggest why you're the better choice. You're not saying "we're better than Brand X," you're just making it crystal clear why someone should choose you instead.
Now, if you're feeling particularly bold (and your lawyers give you the thumbs up), there's the direct callout approach. This is where you explicitly name competitors and explain why you're superior. "Our stuff has better pricing than [competitor's] stuff." "Extra warranty compared to Brand X." It's advertising warfare, but the civilized kind.
The beauty of this framework is that you start conservative and escalate based on your risk tolerance and results. Google's algorithm is smart enough to work out who to put your ads in front of when you include competitive messaging in your ad copy.
The Proof Is in the Targeting
I know an agency owner who used this exact strategy for a premium supermarket client. They set up custom segments targeting people who browse mass market competitor websites, then served them ads highlighting premium quality and better products. The targeting wasn't perfect, it's not like they were remarketing to an exact competitor customer list, but they could guarantee some of those ad impressions were hitting competitor customers at exactly the right moment.
Here's the tactical breakdown: Go to Google Ads Tools > Audience Manager > Custom Segments, then create a custom audience using "people who browse types of websites" and enter your competitor domains. This creates a targetable segment of people who are already interested in your category but shopping elsewhere.
The real magic happens when you apply this to Performance Max campaigns. The platform's automated optimization takes your competitive intercept signals and finds similar warm prospects across Google's entire ecosystem. You're not just stealing customers, you're teaching Google's algorithm to find more people just like the ones already shopping your competitors.
But here's what you absolutely cannot skip: you need genuine product superiority to make this work. If your competitor's "rubbish stuff" is actually better than your "great stuff," this strategy backfires spectacularly. The comparison has to be real, measurable, and defensible.
The Strategic Stakes
Every day you wait is revenue walking into your competitor's bank account instead of yours. These aren't cold prospects you need to educate about your category, they're warm leads already in buying mode, just shopping at the wrong place.
The question isn't whether your competitors' customers would prefer your product. The question is whether you're brave enough to find out. Your competitor's customer base is one Google Ads setting away from becoming your customer base instead.
This is completely legal, totally ethical, and devastatingly effective when executed properly. It's not about being sneaky, it's about being smart enough to fish where the fish already are.
