What is a Slide-in Popup & Why Choose it?

Slide-in means something moves into view from the side or edge of the screen. A slide-in popup is a small lead-capture form. 

For example, a box might slide in from the bottom-right corner, bottom-left corner, or side of the page. It is also known as a flyout or corner box. 

Reasons to choose slide-in popups

• Non-intrusive design: Slide-in popups don’t block your main content. They appear smoothly while visitors are already engaged with the page.
• Better contextual engagement: You can easily match the popup offer with the specific content of the page, making it more relevant and effective.
• Mobile-friendly layout: Slide-ins fit neatly on small screens and don’t take over the entire display.
• Improved user experience: Since they’re less disruptive, visitors are more likely to interact positively, ensuring a smoother signup experience.

Where to Add Slide-in Popups? Where Not?

✅ Where to Add Slide-in Popups

• Blog posts: After a user scrolls 40–60%. They’re already reading, so engagement is higher.
• Product pages: To offer discounts, free shipping, or related products without interrupting the buying flow.
• Resource pages: Offer downloadable guides, checklists, or bonus content related to what they’re viewing.
• Exit-intent (desktop): A subtle last-chance offer before they leave.

❌ Where NOT to Add Slide-in Popups

• Immediately after page load: Feels pushy and reduces trust.
• Checkout pages: Never interrupt payment flow, that kills conversions.
• Login / account pages: Users are task-focused here, so don’t distract them.
• Pages with heavy forms: Too many elements = cognitive overload.
• Very short pages: If there’s barely content, there’s no natural moment to trigger it.

• 제목: Here you can input and edit the main text of the heading block.
• 부제: Offers a field to add secondary text that appears above or below the main Title.
• 제목 설명: It provides a field to add a longer body of text or a brief explanation associated with the heading.
