“Frequency vs. Recency vs. Relevance”: The 3 Mathematical Models Rewriting Media Planning and Marketing in 2025 (and How to Apply Them)

5 Keys to choosing your mathematical model today

This piece breaks down how companies like Coca-Cola and Netflix use neuroscience-based algorithms to optimize ROI—while we expose the common mistakes SMBs and multinationals keep making. Heads up: this isn’t theory. It’s the playbook you need to survive the digital ad jungle.

Make no mistake—whether you’re a tech startup, an auto dealer, or an ice cream shop—there’s no one path. You won’t achieve relevance (the #1 KPI today) with just digital ads, a TV spot, or an influencer.

The F1 Model to Win in Advertising

Just like Formula 1 teams, the winning brands of 2025 run on:

• Real-time data engines (sensors = AI).

• Agile pit stops (A/B testing every 72 hours).

• All-terrain tires (hybrid Relevance + Recency models).

• Miami isn’t the future—it’s the lab where the present is being built. Ready to stop watching from the stands and start owning the track?

• Above all, anchor in reality: events, shows, activations, multi-experiences—the “circus.” That means teams, signage, trucks, promoters. We live in the era of multi-experiences within a single ecosystem.

Frequency:

• Pros: Ideal for product launches.

• Cons: According to Meta, 43% of users block ads if they see them 7+ times per week.

• Miami example: Brickell condo campaigns use 4–6 exposures per month to avoid saturation.

Recency:

• Pros: Increases e-commerce conversions by 31% (Google, 2024).

• Cons: Requires investment in real-time tracking.

• LATAM example: Falabella uses 72-hour post-visit windows to recover abandoned carts.

Relevance:

• Disruptive twist: Combines AI + consumer psychology + real-world events.

• Key stat: Relevance-led campaigns deliver 2.3x higher CTR (Nielsen).

• Spain example: Iberia personalizes offers based on recent searches in Google Flights.

1. It’s vital today to co-create every action and amplify it with real (phygital) events—expanding cultural activations across the widest possible mix of media and touchpoints.

2. Secret tool: Use Google Analytics 4 + Power BI to measure “Decision Time” (a new KPI that predicts sales).

3. Miami alert: 68% of local agencies still don’t use hybrid models (Relevance + Recency), according to a UM School of Communication report.

Why the old Frequency model underperforms in today’s saturated environment

For decades, media planning worshipped reach and frequency—maximize impressions, reinforce the message, build recall. In a hyperconnected world drowning in content, that’s not enough. Audiences are more selective, hyper-informed, and, above all, more demanding.

The Power of Data in the New Advertising

Mathematical Models—From Theory to Practice

Frequency:

• Historical origin: Rooted in Thomas Smith’s “Rule of 7” (1885), now obsolete.

• Common mistake: Repeating without context. Miami startup Seddi boosted sales 90% by capping frequency and layering geotargeting in Wynwood.

Recency:

• Applied neuroscience: The human brain processes recent stimuli 40% faster (MIT study, 2023).

• Success case: Bacardí Mexico drove +18% sales by targeting 24-hour post-bar visits using beacons.

Relevance:

• Key tech: Machine learning fed with urban mobility + social data.

• Spain example: Santander uses ATM withdrawal patterns to offer credit to users pulling €500+ in tourist zones.

Comparative Analysis and ROI

Average ROI Table (2025):

• Frequency: Sales +12% | CPL $8.50 | Implementation 2 weeks

• Recency: Sales +27% | CPL $5.20 | Implementation 3 weeks

Relevance: Sales +49% | CPL $3.90 | Implementation 6 weeks

Must-Have Tools:

• Snowflake: Combine CRM + weather + local Miami events (e.g., concerts at Doral Amphitheater).

• Brandwatch: Track social sentiment and adjust Relevance in real time.

“The future isn’t Frequency or Recency—it’s Right Time, Right Place.” — Philip Kotler, Marketing 6.0 (2024).

FAQs

• Why is Relevance killing Frequency?

Because the 2025 consumer has an 8-second attention span (shorter than a goldfish). Relevance uses AI to serve messages only when purchase intent spikes.

• How do I apply these models in LATAM on small budgets?

Use free tools: Google Trends + Meta Ads Library to forecast trends and model top-brand strategies.

• What’s the most common mistake in Miami campaigns?

81% prioritize English over Spanglish—yet 67% of purchase decisions are made in Spanish (Nielsen, 2025).

• Is Relevance viable for SMBs?

Yes. Example: Café La Carreta in Coral Gables uses WhatsApp Business + geofencing to trigger rainy-day discounts.
