A common pattern among brands advertising on Meta is to launch campaigns on the first day of a promotion and shut them off when the period ends. No preparation before. The result is predictable: an audience that has never heard of the brand, doesn’t know the products, and has no reason to act fast.
Warming up your audience before a promotion is one of the highest-impact structural decisions you can make.
What “Warming Up” an Audience Actually Means
The idea isn’t new. In traditional marketing, any retailer opening a new location knew that unlocking the doors and waiting wasn’t enough. In the days before, there were flyers in the neighbourhood, spots on local radio, a banner on the storefront. The goal wasn’t to sell yet; it was to build anticipation. To make sure people arrived on opening day already curious, already familiar with what they’d find inside.
In digital, the principle is the same. Audience warming is the practice of running campaigns before the promotional window opens, with the goal of building purchase intent rather than driving immediate conversions.
The logic is simple: when someone sees an offer after already having contact with your brand and products, the decision to buy is faster, cheaper, and more likely.
There are a few ways to build that intent:
- Engagement campaigns that introduce the brand or product line to a new audience
- Video views campaigns that establish brand presence without pushing for a click
- Traffic campaigns to seed Meta’s tracking pixel, the code that records who visits your site and what they do, with high-intent visitors before the conversion window opens.
- Conversion campaigns with a purchase objective started early (a campaign set up to optimize for completed purchases, not just clicks or traffic; the most direct route)
That last one is less intuitive, but often the most effective. Running a purchase-objective campaign before the promotion starts means giving the algorithm enough time to find buyers, not just browsers. By the time the offer goes live, your audience has already been filtered for purchase intent, meaning Meta has already identified, from observed behaviour, the people most likely to buy.
What this looks like in practice: the top of the funnel typically delivers low-single-digit ROAS. By the mid-funnel, that figure climbs into the 20–30x range. The bottom, where the pre-warmed audience converts, is where the campaign earns its return. Starting the purchase-objective campaign early moves more of the audience into the higher-performing stages before the promotional pressure is on.
A Real Example: Specialty Cookware Retailer
A client of ours in Canada, the United States, the United Kingdom, Australia and Switzerland (a specialty cookware retailer with physical locations and a strong online presence) runs an annual liquidation sale; a limited window with steep discounts across the entire catalogue.
In 2025, the campaign was profitable. In 2026, on a smaller budget, the results were significantly better. The difference wasn’t money. It was structured.
2026 results:
- ROAS: 35.15×
- Meta-attributed revenue: US$69,888
- Spend: US$2,493
- Cost per purchase: US$9.94
- Revenue 57% higher than in 2025 on 45% less spend
- CPA is 61% lower than in 2025
Three structural decisions explain the improvement.
- The conversion campaign started during the pre-warm phase.
Rather than launching a purchase-objective campaign only when the promotion opened, the campaign went live earlier, already with that objective active. This gave the Meta algorithm time to find real buyers before the promotional window. When the sale started, the audience seeing the ads had already been filtered for purchase intent; it wasn’t cold traffic.
- The landing page showed the products and allowed purchasing.
The destination page used in the campaign wasn’t a dead-end editorial page. It presented the products that would be available in the promotion and allowed visitors to add them to their cart and complete a purchase (but still at full price; the promotional discount would only apply on the right date). Visitors arrived on the day of the sale knowing exactly what they wanted to buy. The conversion click became a formality.
- Geographic ad set structure connected online and in-store.
The 22% growth in physical store revenue during the same period (from CA$818K to over CA$1M) didn’t come solely from the video campaigns. It came from the decision to build location-specific ad sets across all campaigns, targeted to cities with a physical store. The ad didn’t close the online sale; it likely drove the store visit. This reinforces an important point: where you serve an ad determines which channels benefit from the campaign.
The campaign also revealed a gap: mid-funnel content was thinner than it needed to be, creating inconsistency across asset groups. The top and bottom performed well. The consideration layer in between needed more touch points. That’s the thing being built into the next campaign structure.
How to Apply This to Your Next Promotion
You don’t need a large budget to warm an audience. The principle scales down.
Start earlier than feels necessary. A pre-warm phase of 7 to 14 days gives the algorithm enough time to optimize. If your promotion runs for three weeks, the pre-warm should start two weeks before launch (not the day before).
Use a purchase objective from the beginning. Resist the impulse to start with traffic or awareness objectives and switch to conversions when the promotion opens. The algorithm needs time to find buyers. Give it that time before the pressure is on.
Build the right landing page. The destination page for the pre-warm period should show what will be on sale, let visitors explore the products, and offer a direct path to purchase (even if the discount isn’t active yet). You’re selling the anticipation before you sell the product.
Create assets that evolve as the date approaches. Early in the pre-warm, creatives can be more informational: introduce the products, preview what’s coming, build familiarity. As the promotion date gets closer, the tone shifts. Urgency enters the picture: countdown timers, reminders that the window is limited, highlights of the most sought-after items. The creative should match the emotional state of someone who has already been warmed up and is close to making a decision.
Segment by location if you have physical stores. Build ad sets specific to the cities where you have a location. The impact goes beyond online.
Don’t overcomplicate the structure. One video campaign for awareness, one conversion campaign for buyers. Signal quality comes from simplicity. More campaigns and more audiences mean fragmented signals and slower learning.
Conclusion
A good promotion doesn’t start on the day the discounts go live. It starts weeks earlier, when the audience is still cold, and you have time to warm them up without pressure. The algorithm needs that time. So does the consumer.
The difference between a campaign that hits 35× ROAS and one that repeats the market average is rarely in the offer or the budget. It’s in understanding that preparation is part of the campaign, and that the most important work happens before the promotion begins.
