Conversion Best Practices
Targeting
Show to right visitors:

- Traffic source
- Pages visited
- Time on site
- Cart value (e-commerce)
Exclude:
- Recent converters
- Active subscribers
- Customers (different offers)
- Mobile (unless optimized)
Timing
Not too early: Let user engage first Not too late: Before they leave Test: 30s, 45s, 60s start points
Frequency capping:
- Once per session
- Once per 7 days
- After X page views
Offer Strength
Strong offers:
- Free tool/calculator
- Exclusive discount
- Valuable content
- Free shipping
- Early access
Weak offers:
- "Sign up for newsletter"
- Generic "stay connected"
- Vague "updates"
Copy Formulas
Headlines
Offer-focused:
- "Get [valuable thing] free"
- "[X]% off your first order"
- "Unlock [specific benefit]"
Problem-focused:
- "Wait! Before you go..."
- "Don't leave [without benefit]"
- "Still deciding? Here's help."
Curiosity:
- "One more thing..."
- "Psst... insider secret"
- "[Number] of [audience] already have this"
Button Copy
Good:
- "Get My Free [thing]"
- "Yes, I want [benefit]"
- "Send Me the [resource]"
- "Claim My Discount"
Avoid:
- "Submit"
- "Subscribe"
- "Sign Up"
Negative Option
The "no thanks" link can boost conversions:
- "No thanks, I don't want to save money"
- "I'll pay full price"
- "Maybe later"
Use sparingly—can feel manipulative.
Design Principles
Visual Hierarchy
- Headline (largest, bold)
- Value visual
- Supporting copy
- Form/CTA
- Close option
Sizing
- Desktop: 500-600px max width
- Don't cover entire screen
- Mobile: Full-width, not full-height
Contrast
- Stand out from page
- Clear button color
- Readable typography
Animation
- Subtle entrance (fade, slide)
- Don't distract from content
- Fast transition (200-300ms)
Mobile Considerations
Critical Rules
- No full-screen takeovers (Google penalty)
- Easy to dismiss
- Large tap targets
- Consider bottom sheet
- Test thoroughly
Mobile Alternatives
- Slide-in bar
- Bottom banner
- Sticky footer
- In-line forms
