Overlays can enhance ad communication by introducing contextual cues, limited-time offers, and promotional hooks. BigAtom enables brands to apply, update, and personalize overlays at scale—without disrupting Meta’s ad learning phase. While results vary by brand and audience, applying thoughtful overlay strategies can help improve engagement directionally.

1. Align Messaging with Events or Shopping Moments


Tailoring overlay communication to coincide with specific shopping events (e.g., “Black Friday Sale”, “Singles’ Day Special”) tends to resonate more than static, evergreen messaging. Even without changes to discount depth, referencing the event makes the communication more relevant to users.

Best Practice: Use seasonal hooks to refresh overlays during key periods without altering core ad creatives.

2. Highlight Freebie-Based Offers Where Applicable


In categories like Beauty and Personal Care (BPC), overlays promoting free gifts (e.g., “Free Cleanser on Orders Above ₹799” or Buy 1 Get 1 free) have shown to improve user engagement. By using BigAtom’s rule engine, such messages can be applied only to eligible SKUs, keeping the offer experience consistent.

Best Practice: Display freebies only where available using product-level rules for accuracy.

3. Leverage Brand Exclusivity


If a brand or product is exclusive to your platform, calling that out in the overlay can support trust-building and differentiation. This can also be a subtle way to position your platform as a preferred destination.

Best Practice: Use phrases like “Only on [Brand]” or “Exclusive Online” to establish uniqueness.

4. Use Dynamic Pricing Overlays to Pre-Qualify High-Intent Audiences


For high-AOV or premium products, showing the actual product price in the ad overlay can help pre-filter users and attract only serious shoppers. By using BigAtom’s dynamic attributes, you can automatically populate overlays with real-time pricing pulled from your catalog. This ensures transparency and helps improve downstream conversion metrics by reducing irrelevant clicks.

Why it Matters:

Generic messaging for high-ticket items may drive curiosity clicks but not conversions. Showing the price upfront sets expectations and helps reach users who are genuinely in-market for the product.

5. Limit Use of Generic Discount Language


Messages such as “20% Off” tend to blend into the ad landscape, especially during crowded sale periods. More descriptive overlays often perform better directionally.

6. Test Multiple Messages with Rule-Based Segmentation


Use BigAtom’s capabilities to run multiple overlay variations simultaneously across product sets, categories, or audience types. Testing messages like “Free Gift Inside”, “New Launch”, or “Only Today” may surface insights into what resonates most.

Best Practice: Set up controlled tests across high-traffic SKUs to evaluate which overlay communication delivers better engagement or conversion behavior.


Not all overlays that drive high CTR lead to high-quality traffic. Conversely, certain overlays may reduce broad clicks but result in better AOV or conversion rates by pre-qualifying interested users. Evaluate overlays holistically—consider metrics like conversion rate, and AOV alongside CTR.
