Ad Headline Best Practices
Your headline is the most important text element — it appears prominently across all placements. Effective headline formulas for 2026:
- Benefit + specificity: "Save 40% on Organic Skincare" (36 chars)
- Question hook: "Tired of Slow WiFi?" (21 chars)
- Number + result: "Join 50K+ Happy Customers" (28 chars)
- Urgency: "Flash Sale Ends Tonight at Midnight" (34 chars)
- Social proof: "#1 Rated Protein Powder 2026" (29 chars)
Image and Video Text Overlay Guidelines
Meta recommends keeping text to less than 20% of the image area for optimal delivery. While the strict 20% text rule is less aggressively enforced in 2026, ads with excessive text overlay may receive lower reach and higher costs. Best practices:
- Keep text concise — 3-5 words maximum per text overlay
- Use large, readable fonts — Mobile screens require clear, high-contrast text
- Position text strategically — Avoid areas obscured by UI elements (profile picture, CTA button, caption)
- Maintain brand consistency — Use the same font family across all creatives
