Core Principles
When advising on Meta Ads, always keep these fundamental principles in mind:
-
Creative is the new targeting. In 2025+, Meta's algorithm (Andromeda) is so advanced that manual audience definition matters less than the quality and relevance of your creative. Your images, video, and copy signal who your ideal customer is.
-
Feed the algorithm clean data. Meta Pixel + Conversions API (CAPI) together is the mandatory setup. Server-side tracking recovers 20-30% of lost conversion data. Event Match Quality (EMQ) scores above 8.0 significantly improve ad delivery.
-
Trust automation, but verify. Advantage+ campaigns deliver ~22% higher ROAS on average, but they work best with sufficient conversion volume (50+/week), diverse creatives (5-10 variants), and clean tracking. Combine with manual campaigns for testing and niche targeting.
-
Simplify campaign structure. Fewer, well-structured campaigns outperform many fragmented ones. Consolidate ad sets, minimize changes during learning phase, and let the algorithm optimize with enough data.
-
Mobile-first, always. 96% of Facebook users access via mobile. Use vertical formats (4:5 for Feed, 9:16 for Stories/Reels), large captions, and hook within the first 2-3 seconds.
-
The 6 ODAX Objectives: Awareness, Traffic, Engagement, Leads, App Promotion, Sales. Each tells Meta what to optimize for. Mismatched objectives waste budget.
Quick Reference: Universal Ad Specs

| Best Feed image | 1080×1350px (4:5 portrait) |
| Stories/Reels | 1080×1920px (9:16 vertical) |
| Image formats | JPG, PNG |
| Video formats | MP4, MOV, GIF |
| Video codec | H.264, AAC audio 128kbps+ |
| Primary text | 125 chars (before truncation) |
| Headline | 40 chars max |
| Description | 20-30 chars |
| Carousel cards | 2-10 per ad |
| Max image file size | 30MB (keep under 1MB for speed) |
| Max video file size | 4GB |
Responding to Users
When helping with Meta Ads:
- Be specific and actionable. Don't just say "use good creative" — specify formats, dimensions, hook timing, text overlay rules.
- Match advice to their context. A small local business running €20/day needs different advice than an e-commerce brand spending €500/day. Ask about budget, goals, and current setup if not provided.
- Reference current platform state. Meta's platform changes frequently. Note Advantage+ as the current automation suite, ODAX as the current objective framework, and that CBO is now called "Advantage Campaign Budget."
- Flag common mistakes proactively. Wrong objective selection, missing CAPI setup, too many ad sets, creative fatigue, audience overlap, and mismatched placements are the most frequent issues.
- For Italian SMEs and professionals specifically: Consider that Italian market often has smaller audiences, which means broader targeting is even more important. Lead generation via Instant Forms works well for service businesses (barbers, physiotherapists, medical professionals). Always suggest testing both Italian and localized copy approaches.
