Call-to-Action Buttons: Design, Copy, and Placement

The call-to-action button is where conversions happen. Everything else on your page leads to this moment—the click that converts a visitor into a lead or customer.

Yet CTA buttons are often an afterthought. Getting them right can significantly improve conversion rates.

Why CTAs Matter

The Moment of Commitment

The CTA is where intent becomes action:

• All your messaging leads here
• All your design points here
• The user decides: act or leave

Incremental Gains Compound

A CTA improvement that increases clicks by 10% improves your entire funnel by 10%. Small optimizations compound across thousands of visitors.

CTA Copy: What to Write

Action-Oriented Language

Start with a verb that describes the action:

• Get: “Get Started,” “Get the Guide”
• Start: “Start Free Trial,” “Start Learning”
• Download: “Download Now,” “Download Free PDF”
• Join: “Join Now,” “Join 10,000+ Members”
• Try: “Try It Free,” “Try for 30 Days”

Avoid Generic Text

Weak CTAs:

• “Submit”
• “Click Here”
• “Learn More”
• “Continue”

Why they’re weak: They don’t communicate value or specific action.

Value-Focused Copy

Tell users what they’ll get:

• ❌ “Submit”

• ✅ “Get My Free Guide”

• ❌ “Sign Up”

• ✅ “Start My Free Trial”

• ❌ “Register”

• ✅ “Reserve My Spot”

First Person vs. Second Person

First person (“My”):

• “Start My Trial”
• “Get My Quote”
• Creates ownership

Second person (“Your”):

• “Start Your Trial”
• “Get Your Quote”
• Direct address

Testing shows first person often performs slightly better, but test for your audience.

Urgency and Scarcity

When appropriate:

• “Get It Now”
• “Start Today”
• “Limited Spots Available”
• “Offer Ends Friday”

Only use if genuine—fake urgency damages trust.

Reducing Friction

Address anxiety in the button or nearby:

• “Start Free Trial — No Credit Card Required”
• “Get Quote — Takes 30 Seconds”
• “Download Free — No Email Required”

CTA Design: How It Looks

Color

Contrast is key: The button must stand out from surrounding content. There’s no “best” color—the best color is the one that contrasts most with your page.

Common approaches:

• Brand accent color (if it contrasts)
• Complementary color to page palette
• Orange/green often test well (but context matters)

What to avoid:

• Same color as background
• Same color as other elements
• Muted colors that don’t pop

Size

Big enough to notice:

• Larger than seems necessary
• Especially on mobile (44px minimum height)
• Proportional to its importance

But not overwhelming:

• Shouldn’t dominate the entire page
• Balance with surrounding content

Shape

Common button shapes:

• Rounded corners (most common, friendly)
• Pill-shaped (fully rounded, modern)
• Square corners (formal, classic)
• Custom shapes (brand-specific)

Rounded corners tend to perform well and feel clickable.

Visual Weight

Make the CTA look “clickable”:

• Solid fill (not just outline)
• Subtle shadow or depth
• Hover state that changes appearance
• Cursor change to pointer

Whitespace

Don’t crowd the button:

• Space around the CTA
• Visual breathing room
• Nothing competing for attention
• Clear isolation draws focus

CTA Placement: Where It Goes

Above the Fold

Primary CTA should be visible without scrolling:

• Immediate opportunity to act
• Captures high-intent visitors
• Works for those who don’t scroll

After Value Proposition

Place CTAs after explaining value:

• After headline/subheadline
• After key benefit
• After social proof

Multiple Placements on Long Pages

For long-form content:

• Above the fold (first CTA)
• Mid-page after major section
• End of page (final CTA)
• Sticky CTA (always visible)

Rule: User should never have to scroll far to find a CTA.

Sticky/Fixed CTAs

For certain pages:

• Floating button that scrolls with page
• Sticky bar at bottom (mobile)
• Always visible when user is ready

Caution: Don’t obstruct content or annoy users.

Near Supporting Elements

Place CTAs near:

• Social proof (testimonials, reviews)
• Trust signals
• After addressing objections

Primary vs. Secondary CTAs

Visual Hierarchy

Primary CTA:

• Most prominent
• Filled button
• Brand/accent color
• Main goal of page

Secondary CTA:

• Less prominent
• Outline or ghost button
• Subdued color
• Alternative action

Example:

• Primary: “Start Free Trial” (solid orange button)
• Secondary: “Watch Demo” (outline button)

When to Use Secondary CTAs

• Different levels of commitment
• Alternative paths (buy vs. learn more)
• Different offers (free vs. paid)

Caution: Too many CTAs dilute focus. Limit to 2 options maximum.

CTA Context

Supporting Copy

Text near the CTA that supports conversion:

Before button:

• “Join 50,000+ happy customers”
• “No credit card required”
• “Cancel anytime”

After button (if applicable):

• “Takes less than 60 seconds”
• “You’ll receive instant access”

Form + Button

For forms, the button should:

• Be full-width or prominent within form
• Clearly indicate form submission
• Repeat value prop: “Get My Free Guide” not “Submit”

Mobile CTA Considerations

Touch-Friendly

• Minimum 44px height
• Easy to tap with thumb
• Not too close to other elements

Placement

• Bottom of screen is thumb-friendly
• Consider sticky bottom bar
• Above-fold priority even more important

Testing on Actual Devices

• What looks good on desktop may not work on mobile
• Test on real phones
• Consider different screen sizes

Testing CTAs

What to Test

Copy:

• Action verbs
• First person vs. second person
• With/without urgency
• Length (short vs. descriptive)

Design:

• Button color
• Size
• Shape
• With/without icons

Placement:

• Above vs. below fold
• Number of CTAs
• Sticky vs. static

How to Test

• A/B test one element at a time
• Adequate sample size (conversion-based)
• Track click rate and conversion rate
• Consider downstream metrics too

Metrics

Primary:

• Click-through rate on button
• Conversion rate

Secondary:

• Downstream conversion (did clickers become customers?)
• Bounce rate
• Scroll to CTA rate
