The fastest way to scale your ads profitably is to find more customers like the ones you already have. An AI lookalike audience builder analyzes your customer data and finds new prospects who match the profile of your best buyers — so you can target them with ads that convert.
What Is An AI Lookalike Audience Builder?
An AI lookalike audience builder uses machine learning to analyze your existing customer data — demographics, behaviors, purchase history — and find new prospects who share the same characteristics. These lookalike audiences convert at a higher rate because they match your best customers.
Step 1: Upload Your Customer Data
Upload your customer list — names, emails, phone numbers, and any attributes you have. The more data you provide, the more accurate the lookalike audiences.
Step 2: Identify Your Best Customers
Tell the AI which customers are your best — highest lifetime value, most frequent purchases, or highest order value. The AI builds lookalike audiences based on those customers specifically.
Step 3: Build Lookalike Audiences
The AI creates lookalike audiences on Facebook, Instagram, Google, LinkedIn, and TikTok — new prospects who match your best customers. Start with a 1% lookalike for the highest match quality, then expand.
Step 4: Scale Profitably
Test your lookalike audiences with a small budget first. Scale the ones that convert and pause the ones that do not. The AI continuously refines the audiences based on performance.
We use an AI lookalike audience builder to find more customers like your best ones — starting at $250/week.
