Prospecting

What prospecting means

Prospecting campaigns go after people who do not know you. You exclude existing audiences (site visitors, buyers, email subscribers) and buy reach among everyone else. Broad targeting, interest stacks, lookalike audiences (new people who resemble a list of buyers you already have), and most YouTube or TikTok reach buying sit here.

The exclusion list is what makes it prospecting. If site visitors and past buyers are still eligible, you are running a blended campaign and calling it cold.

Let's take a drink brand as an example. They sell a low-sugar sports drink for active women over 50, mostly from their own website. The drink brand advertises on Meta (Facebook and Instagram), TikTok, and YouTube. On Meta, the prospecting campaign excludes anyone who visited the drink brand's website in the last 30 days and anyone who already bought. The people who see those ads have no relationship with the drink yet.

Why prospecting matters

Nothing else in the account works without it. Retargeting (ads to people who already visited, watched, or bought) can only re-approach people prospecting already reached. Cut prospecting and the retargeting pool drains a few weeks later, usually right after someone praised the efficiency.

Prospecting is also where CAC (customer acquisition cost: what you spend to win a genuinely new customer) actually gets decided. Cheap conversions from warm audiences flatter the average and hide what a genuinely new customer costs.

Let's take a drink brand as an example. They sell a low-sugar sports drink for active women over 50, mostly from their own website. A month of Meta (Facebook and Instagram) spend looked efficient after the drink brand shifted budget into retargeting. New customer counts fell the next month, because fewer strangers had ever landed on the site. The cheap retargeting line had been feeding on the expensive prospecting line.

How to read prospecting results

Judge prospecting on new customers and total revenue, not on the platform return next to the campaign name. A prospecting campaign that lifts overall sales while showing a mediocre return on ad spend is doing its job.

Let's take a drink brand as an example. They sell a low-sugar sports drink for active women over 50, mostly from their own website. The drink brand spends $40,000 on Meta ads (Facebook and Instagram) in one month. $28,000 of that $40,000 goes to prospecting (ads to people who have never engaged). $12,000 of the $40,000 goes to retargeting (ads to people who already visited). Prospecting is credited with 200 new customers. Divide $28,000 of prospecting spend by 200 new customers. That is $140 per new customer. Retargeting is credited with 240 orders at $50 of ads each. The retargeting line looks like the winner. Then the drink brand counts how many of those 240 retargeting orders were people who would have bought anyway. About 120 of the 240 orders (half) were. The honest new-customer cost still lives on the prospecting line.

Watch new-to-file share (the share of buyers who had never purchased before) and incrementality tests (turn the ads off in a matched group and see whether total sales move) rather than last-click. If total orders move when you scale prospecting, the campaign is working even when the dashboard disagrees.

Common prospecting mistakes

• Comparing prospecting return to retargeting return and cutting the loser.
• Forgetting to exclude buyers, then reporting warm conversions as cold ones.
• Rotating audiences every week so nothing ever exits the learning phase (the unstable period after you launch or heavily edit a Meta ad set).
