Best Practices

Display Ads

• Brand Consistency: Use consistent colors, fonts, and visual style across all sizes
• Clear Hierarchy: Establish visual hierarchy - image, headline, CTA
• Minimal Text: Let imagery do the heavy lifting; Google prefers image-focused ads
• High Contrast: Ensure readability across different website backgrounds
• CTA Visibility: Make call-to-action buttons stand out clearly

YouTube Thumbnails

• Face Forward: Human faces with eye contact increase click-through rates
• Bold Colors: Use contrasting colors that pop against YouTube's white interface
• Readable Text: If adding text, ensure it's legible at small sizes
• Emotional Expression: Show strong emotions to trigger curiosity
• Avoid Clutter: Keep composition simple and focused

Discovery Ads

• Native Feel: Design to blend with organic content, not look like ads
• Aspirational Imagery: Use lifestyle images that inspire action
• High Quality: Discovery placements favor premium-looking content
• Mobile-First: Design for mobile screens where most Discovery traffic comes from

Performance Max

• Asset Variety: Provide multiple images in different ratios for ML optimization
• Consistent Branding: Maintain visual consistency across all asset variations
• Test Different Styles: Mix lifestyle and product-focused images
• Avoid Text in Images: Google's ML works better with text-free images

Responsive Display

• Test All Combinations: Design images that work with any headline/description
• Safe Zones: Keep important elements away from edges (15% margin)
• Scalability: Ensure images look good from 300px to 1200px wide

Prompt Tips for Google Ads

When creating Google ad creatives, include these details in your prompt:

1. Exact Dimensions: Specify pixel size or aspect ratio (300x250, 1.91:1, etc.)
2. Ad Format: Mention if it's for Display, YouTube, Discovery, or Performance Max
3. Product/Service: Clearly describe what you're advertising
4. Visual Focus: What should be the main visual element?
5. Color Scheme: Brand colors or desired palette
6. Text Space: Request space for headlines, descriptions, or CTAs
7. Style Reference: Professional, playful, minimal, bold, etc.

Example Prompt Structure

"Create a [dimensions] [ad format] for [product/service].
Show [visual description] with [color scheme/style].
Leave space for [text elements].
[Additional requirements like brand guidelines, urgency, etc.]"

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"
