Step-by-Step Guide: How to Set Up Sticky Add to Cart on Your Shopify Store
April 28, 2025
In today's competitive e-commerce landscape, optimizing your Shopify store for conversions is essential for success. One of the most effective yet underutilized tools for boosting conversion rates is the sticky add to cart button. This feature keeps your call-to-action visible as customers scroll through your product pages, significantly reducing purchase friction. In this comprehensive guide, we'll walk you through the entire process of setting up sticky add to cart functionality on your Shopify store using the Libautech Sticky Add to Cart app.
Why Your Shopify Store Needs a Sticky Add to Cart Button
Before diving into the implementation process, let's briefly examine why sticky add to cart buttons are so effective:
The Mobile Shopping Experience Problem
Approximately 60% of e-commerce traffic comes from mobile devices, where screen space is limited and product pages require extensive scrolling. When customers reach the bottom of a product page after reading descriptions and reviews, they often face the friction of scrolling back up to find the purchase button—a common point of cart abandonment.
The Conversion Impact
Shopify stores implementing sticky add to cart buttons typically see:
15-30% increase in mobile conversion rates
Reduced cart abandonment
Improved customer satisfaction
Higher engagement with product page content
As one Shopify seller noted: "When the customer is on your site and he's scrolling through your product page, it's good to always have visible Add to Cart or Buy now button. Because when he's reading all the information and he's ready to purchase your product, he doesn't need to scroll back up, he just needs to click on the Buy now and he will buy your product."
Now that we understand the importance of this feature, let's implement it on your store.
Step 1: Installing the Libautech Sticky Add to Cart App
The first step in adding sticky add to cart functionality to your Shopify store is installing a reliable app designed for this purpose. The Libautech Sticky Add to Cart app offers comprehensive features with a user-friendly interface.
After installation, you'll be redirected to the app dashboard
You'll notice the app offers a 14-day free trial to test its effectiveness
Step 2: Configuring Mobile Settings
Since mobile optimization is crucial for e-commerce success, we'll start by configuring the mobile version of your sticky add to cart button.
Select Mobile Configuration:
In the app dashboard, locate the "Mobile" tab
You'll see several pre-made templates to choose from
Choose a Template:
For mobile devices, simplicity often works best
The "Just Button" or "Standard" templates are popular starting points
Click on your preferred template to select it
Customize Button Appearance:
Edit the button text (e.g., "Add to Cart," "Buy Now," "Get It Now")
Adjust the button colors to match your brand (both background and text)
Consider adding an icon (like a shopping cart) for better visual recognition
Configure Button Behavior:
Decide where customers should go after clicking the button:
Redirect to checkout (fastest path to purchase)
Add to cart and stay on page
Add to cart and open cart drawer
Add to cart and redirect to cart page
Add Product Information:
Decide what product information should appear on your sticky bar:
Product title
Price
Variant selectors (if applicable)
Quantity picker
Set up Attention Badges (Optional):
These badges can significantly increase conversions
Navigate to the "Badges" section
Select "Limited Stock" or another attention badge
Customize the text and appearance
Configure badge behavior (e.g., show only when inventory is below 5 items)
Step 3: Configuring Desktop Settings
While mobile optimization is crucial, desktop users still account for a significant portion of e-commerce traffic. Let's configure the desktop version of your sticky add to cart button.
Select Desktop Configuration:
Navigate to the "Desktop" tab in the app dashboard
Review the template options available
Choose a Template:
Desktop allows for more complex layouts
Popular options include:
Full-width bar (maximizes visibility)
Half-width bar (less intrusive)
Compact bar (minimal screen space usage)
Rounded bar (softer visual appearance)
Customize Appearance:
Adjust colors to match your brand identity
Set font styles and sizes
Position the bar (typically bottom or top of screen)
Configure Desktop-Specific Features:
Desktop screens offer more space for additional elements:
Product image thumbnail
Star ratings
Savings amount
Stock level indicators
Set Display Conditions:
Configure when the sticky button should appear:
Immediately visible
Appear after scrolling past the original add to cart button
Appear after scrolling a certain distance
Step 4: Adding Attention Badges for Improved Conversions
Attention badges are powerful conversion tools that create urgency and encourage immediate purchases. Let's set these up for maximum impact.
Navigate to Badge Settings:
Locate the badge configuration section in your app dashboard
This may be under "Expand All Settings" or similar
Choose Badge Types:
Limited Stock: "Only X Left" (ideal for creating scarcity)
Select colors that create contrast with your button
Choose appropriate icons to reinforce the message
Ensure text is brief but impactful
Configure Badge Logic:
For inventory-based badges, set the threshold (e.g., show when fewer than 10 items remain)
For time-based badges, set display schedules
For custom badges, determine display rules
As one Shopify seller explained: "When your customer is on your product page and looking through and wants to buy this product, it's a good thing to show Urgency badge example as a limited stock. It works very well on sticky add to cart bar where customers reading about your product and he always sees that there's only two left and that creates urgency for him to purchase that product because he knows if he doesn't buy today, maybe tomorrow there won't be that product."
Step 5: Advanced Configuration Options
To truly customize your sticky add to cart experience, explore these advanced options:
Variant and Quantity Selectors:
Decide whether to include variant pickers (color, size, etc.)
Configure quantity selector appearance and behavior
Set minimum and maximum quantity limits if applicable
Custom CSS (Optional):
For those with technical knowledge, custom CSS allows for precise styling
Access this feature in the advanced settings section
Use to match exact brand specifications
Display Rules:
Set conditions for when the sticky button appears:
All product pages
Specific collections only
Specific products only
Based on inventory levels
Integration with Other Apps:
Configure how your sticky add to cart works with other Shopify apps:
Upsell apps (like Libautech Smart Upsell)
Currency converters
Reviews apps
Step 6: Testing Your Implementation
Before finalizing your setup, thorough testing is essential to ensure optimal performance:
Cross-Device Testing:
Check appearance and functionality on:
Multiple mobile devices (iOS and Android)
Tablets
Desktop computers
Different browsers
Functionality Testing:
Test the complete user journey:
Adding products with different variants
Changing quantities
Button redirect behavior
Badge display logic
Speed Impact Assessment:
Ensure the sticky add to cart implementation doesn't negatively impact your page load times
Use Google PageSpeed Insights to compare before and after implementation
User Feedback Collection:
Consider using a feedback tool to gather initial customer opinions
Watch for any confusion or friction points
Step 7: Optimization Strategies
After your initial implementation, consider these optimization strategies to maximize conversion impact:
A/B Testing Different Configurations:
Test different button text variations
Compare different attention badges
Evaluate various color schemes
Assess different positioning options
Segment-Specific Customization:
Create different experiences for different customer segments:
New vs. returning visitors
Mobile vs. desktop users
Discount-seeking vs. premium shoppers
Product-Specific Customization:
Consider different configurations for different product types:
High-value items might benefit from more detailed information
Low-cost impulse buys might work better with simplified buttons
Products with many variants need more space for options
Seasonal Adjustments:
Update badges and messaging for holidays and sales events
Create urgency during peak shopping seasons
Highlight limited-time offers during promotions
Step 8: Integrating with Upsell Opportunities
To maximize the value of each customer, consider integrating your sticky add to cart with upsell functionalities:
Install Complementary Apps:

There's often a package deal available ($9.99 for both apps together)
Configure Post-Add-to-Cart Upsells:
Set up offers that appear after customers click the sticky add to cart button
Focus on relevant, complementary products
Consider offering a discount on the upsell item
Set Up Bundle Offers:
Create "frequently bought together" bundles
Display these near your sticky add to cart button
Highlight the savings available when purchasing bundles
Implement "Complete the Look" Suggestions:
Particularly effective for fashion and home decor

Create urgency with limited-time bundle discounts
Step 9: Measuring Success
