Headline Writing Best Practices
Include your primary keyword: At least 2-3 headlines should contain your main keyword to improve ad relevance and Quality Score.
Vary your messaging: Create headlines that highlight different benefits, features, and value propositions. Avoid repetitive headlines.
Use numbers and statistics: Headlines like "Save 40% Today" or "Trusted by 50,000+ Users" perform well.
Include CTAs: Action-oriented headlines like "Get Started Free" or "Request a Demo" drive clicks.
Pin strategically: Pin your most important headline (usually containing the keyword) to position 1 to ensure it always shows.
Description Writing Best Practices
Expand on your headlines: Use descriptions to provide more detail about your offer, benefits, and unique selling propositions.
Include social proof: Mention awards, ratings, customer count, or years in business to build trust.
Add urgency when appropriate: Limited-time offers or exclusive deals can improve click-through rates.
End with a clear CTA: Tell users exactly what action you want them to take.
