Lower Shopify CAC: 7 Proven Strategies

Jacob Bytom Updated on Mar 17, 2025

Lowering your customer acquisition costs (CAC) on Shopify doesn’t have to mean cutting corners or chasing every new trend. It comes down to making smarter moves across your store—from how you run ads to how your site performs. In this guide, we’re breaking down seven practical strategies that actually help you spend less to gain more customers. Whether you're just starting out or looking to sharpen your current approach, these methods can make a noticeable difference in how far your budget goes.

1. Fine-tune Your Ad Spend

Getting the most out of your ad budget starts with precise targeting and careful planning. Focus on narrowing your audience and using tools that make every dollar count.

Implement Advanced Audience Targeting

Target your audience based on factors like age, location, income, shopping habits, website activity, and interests. For example, if you sell high-end skincare products, aim your ads at individuals interested in luxury beauty items who are likely to have higher purchasing power.

Optimize Your Ad Campaigns

Run small-budget tests for your ads. Keep an eye on metrics like click-through rate (CTR), cost-per-click (CPC), conversion rate, and return on ad spend (ROAS). Regularly reviewing these numbers allows you to make informed adjustments, improving results while keeping costs down.

Use Platform-Specific Features

Different platforms come with tools designed to boost your campaigns:

Facebook: Use Lookalike Audiences to find users similar to your top customers.
Google Ads: Take advantage of automated bidding strategies to optimize bids based on the likelihood of conversions.
Instagram: Add Shopping Tags to your posts, making it easy for users to shop directly.

Test and Refine Ad Creative

Experiment with your ad elements through A/B testing. Try out different headlines, images, copy, and formats (like carousel ads versus single-image ads) to see what resonates best with your audience.

Once your ads are live, keep a close watch on their performance:

Review overall campaign results
Pause ads that aren’t performing well
Increase spending on campaigns that are delivering strong results
Adjust bidding strategies and update targeting as needed

Adapt your budget to seasonal trends. For example, allocate more funds during busy shopping periods like Black Friday and scale back during slower times.

2. Build Free Traffic Through SEO

Targeted ads can deliver quick results, but SEO helps drive consistent, long-term traffic while keeping customer acquisition costs low. Here's how to effectively attract organic visitors to your Shopify store.

Optimize Your Product Pages

Focus on creating product pages that are both search-engine friendly and appealing to shoppers:

Use descriptive, keyword-focused titles to help search engines and users.
Write original product descriptions instead of copying manufacturer text.
Add alt text to images for better accessibility and improved SEO.
Create compelling meta descriptions to attract clicks from search results.

Technical SEO Basics

A solid technical setup ensures your store performs well in search engines:

Use keyword-rich, logical URLs for easy navigation.
Enable SSL certification to secure your site and boost rankings.
Compress images and clean up code to improve page load speed.
Generate an XML sitemap to help search engines index your pages.
Implement schema markup to enhance your search result listings.

Content Strategy for Better Rankings

Help your audience at every stage of their buying journey with targeted content:

Create buying guides for your product categories.
Start a blog that addresses customer interests and questions.
Develop resource pages to answer FAQs and provide useful info.
Write comparison content to help shoppers make informed decisions.

Mobile Optimization

With more shoppers using mobile devices, make sure your store is mobile-friendly:

Test mobile responsiveness to ensure your site works seamlessly on different devices.
Check load speeds across smartphones and tablets.
Design easy-to-click buttons for smooth navigation.
Simplify menus and navigation to keep users engaged.

Track Your SEO Performance

Use analytics tools to keep an eye on key metrics like organic traffic, keyword rankings, page speed, and user engagement. Regularly reviewing this data helps you refine your strategy.

Local SEO Efforts

Combine your broader SEO strategy with local optimizations to reach nearby customers:

Create location-specific landing pages to target local audiences.
Optimize your Google Business Profile for better visibility in local searches.
Build local citations and backlinks to strengthen your online presence.
Incorporate location-based keywords into your content.

If you're looking for tailored SEO strategies or advanced optimizations for your Shopify store, working with experts can make a big difference. Agencies like UltraLabs specialize in building Shopify stores that are optimized for both conversions and SEO, helping you boost your rankings and attract more organic traffic.

3. Set Up Email Marketing Systems

Email marketing is an affordable way to build relationships with leads and increase conversions. Here’s how to create email workflows that can help reduce your customer acquisition costs.

Welcome Series Automation

Kick off your email strategy with a welcome series that connects with new subscribers:

Day 1: Send a welcome email featuring a discount code.
Day 3: Share your brand story and what sets you apart.
Day 5: Highlight your best-selling products, including social proof.
Day 7: Offer helpful, product-related content.

Abandoned Cart Recovery

Recover lost sales by automating abandoned cart emails:

First Reminder (1 hour): Show the abandoned items with images and a direct link to the cart.
Second Notice (24 hours): Add urgency by mentioning low stock and include customer reviews.
Final Opportunity (72 hours): Offer a limited-time discount (e.g., 10–15% off) to encourage checkout.

Post-Purchase Sequence

Encourage loyalty and additional purchases with a post-purchase email series:

Order Confirmation: Include tracking information and delivery details.
Delivery Follow-Up: Ask for product reviews to build trust.
Cross-Sell Opportunity: Suggest related items your customer might like.
Replenishment Reminder: Send reminders based on typical product usage timelines.

Below is a simple automation setup using Klaviyo. This visual outlines a common abandoned cart sequence—starting with a trigger when someone begins checkout, a short delay, and a conditional check to determine whether the order was completed. If not, it moves the user into a follow-up email. This kind of structure helps bring shoppers back with minimal manual effort.

Platform Integration

Choose the right platform to streamline email automation on Shopify:

Platform	Key Features	Ideal For
Klaviyo	Advanced segmentation, predictive analytics	High-volume stores
Omnisend	Simple automation, SMS integration	Multi-channel retailers
Shopify Email	Built-in integration, easy to set up	Newer stores

Segmentation Strategy

Refine your email campaigns by dividing your audience into smaller groups:

Purchase History: Differentiate between first-time and repeat customers.
Average Order Value: Group customers by spending habits.
Product Categories: Focus on specific product interests.
Geographic Location: Tailor messages to local preferences.
Engagement Level: Separate active subscribers from inactive ones.

Track these metrics to measure email success:

Open Rate: Aim for 15–25%.
Click-Through Rate: Shoot for 2–5%, especially for retail.
Conversion Rate: Expect 1–5%, depending on the email type.
Revenue per Email: Check the ROI for each campaign.
Unsubscribe Rate: Keep this below 0.5%.

Regularly analyzing these numbers will help you refine your approach and improve results.

Email Design Best Practices

Make sure your emails are visually appealing and effective:

Clear Call-to-Action: Use buttons with contrasting colors to grab attention.
Concise Copy: Keep your message short and easy to skim.
Responsive Layout: Ensure emails look great on all devices.
Optimized Images: Compress images to reduce load times.
Brand Consistency: Stick to your brand’s visual identity.

For campaigns that drive revenue, consider teaming up with experts like UltraLabs. These email strategies not only cut acquisition costs but also set the groundwork for deeper customer engagement in the next steps.

4. Get Customers to Create Content

Encouraging your customers to share their experiences can be a budget-friendly way to build trust and attract new buyers. This approach reduces the need to rely heavily on paid advertising.

One way to do this is by automating post-purchase feedback requests. A simple follow-up message can encourage happy customers to share their thoughts, giving you valuable insights without extra marketing costs.

Ask your customers to share photos or videos of your products in action. Featuring these real-life experiences on your product pages can increase visitor confidence and make them more likely to buy. Visual content, in particular, helps establish trust quickly.

If you’re looking to take this strategy further, you might want to work with experts like UltraLabs (https://ultralabs.digital), who specialize in optimizing Shopify stores for better conversions.

5. Create Smart Discount Programs

Smart discount programs can help you attract new customers while keeping your profit margins intact. By carefully analyzing your product margins, you can set discounts that are enticing yet sustainable. For example, offering first-time discounts can encourage new buyers without cutting too deeply into your profits.

Here are some discount strategies that work well:

Time-limited welcome offers: A 24-hour discount for new email subscribers can drive quick purchases and grow your email list.
Bundle discounts: Encourage customers to buy more by offering discounts on product bundles, which also help maintain healthy margins.
Free shipping thresholds: Set a minimum order value slightly above your average purchase level to encourage larger orders.

Timing is everything when it comes to discounts. Consider these approaches:

Offer larger, short-term discounts during major events like store launches.
Provide smaller, ongoing discounts exclusively for email subscribers.
Use tiered discounts, like "buy more, save more", during busy shopping seasons.

To ensure you're getting the most out of your discounts, track the customer lifetime value (CLV) for each promotion. This data can help you identify which strategies encourage repeat purchases. Also, make sure to clearly communicate discount terms and expiration dates to create a sense of urgency.

6. Make Your Website Easy to Use

An easy-to-navigate website helps lower customer acquisition costs. When users can quickly find what they need and complete purchases, your business spends less on acquiring each customer.

Speed Optimization

A fast website keeps visitors engaged and reduces bounce rates. To improve loading times:

Compress images while maintaining quality
Enable browser caching for repeat visitors
Minimize and combine JavaScript and CSS files
Use a content delivery network (CDN) to serve content faster

Good navigation makes it easier for customers to find products. Include:

A visible search bar in the header
A well-structured category menu
Filters for narrowing down product searches
Features like "Recently viewed" items and breadcrumb trails

Streamline Checkout

A simple checkout process encourages more conversions. Focus on:

Allowing guest checkout for convenience
Using progress indicators to show steps
Offering multiple payment methods
Adding address auto-complete to save time

With more shoppers using their phones, mobile usability is key. Ensure your site has:

Large, tappable buttons and touch-friendly design
Text that’s easy to read without zooming
Fast-loading images for mobile users
A smooth cart and checkout experience

If you need help with technical adjustments, experienced Shopify developers can make a big difference. UltraLabs, for instance, specializes in building Shopify stores that are optimized for conversions and usability.

Trust Signals! Important

Reassure customers by adding trust-building elements:

Display security badges near the checkout
Show customer reviews on product pages
Include clear links to your return policy
Use SSL certificates and provide contact details

These updates not only improve the shopping experience but also support cost-effective customer acquisition efforts.

7. Start a Customer Referral Program

After refining your website’s usability and introducing smart discounts, take it a step further with a referral program to drive growth without overspending.

Customer referral programs tap into your existing customer base to bring in new buyers at a much lower cost than traditional advertising methods. When done right, they can be a game-changer for your business.

Choose the Right Rewards

The success of your referral program hinges on offering the right incentives. Here are some ideas:

Provide store credit, percentage discounts, or exclusive products for both the referrer and the new customer.
Ensure rewards are only released after the referred customer makes their first purchase.
Set clear eligibility rules and timelines for claiming rewards.
Offer incentives that attract participants while keeping your profit margins intact.

Set Up Your Program Structure

A well-structured program is key to avoiding confusion and misuse. Focus on these elements:

Define minimum purchase requirements to qualify for rewards.
Set expiration dates for rewards to encourage timely use.
Implement fraud prevention measures to protect your program.
Use unique referral codes to track referrals accurately.

Select Reliable Software

Shopify offers several apps that make managing your referral program simple. Here are a few options:

App Name	Key Features	Best For
ReferralCandy	Automated rewards, fraud detection, analytics dashboard	High-volume stores
Smile.io	Points system, VIP tiers, social sharing tools	Multi-channel retailers
Conjured Referrals	Easy setup, customizable rewards, budget-friendly	Small to medium-sized stores

Track and Optimize Performance

To ensure your program delivers results, monitor these key metrics:

Participation rate: How many existing customers are joining the program?
Referral conversion rate: Are referred customers making purchases?
Cost per referred customer: How much are you spending to acquire each one?
Average order value: Are referrals spending more or less than other customers?
Customer lifetime value: How valuable are referred customers over time?

Use this data to fine-tune your program and make sure it’s easy for customers to participate.

Simplify the referral process by offering multiple sharing options:

Ready-to-use email templates for personalized invites.
Social sharing buttons for platforms like Facebook, Twitter, or Instagram.
A mobile-friendly design to cater to smartphone users.
Clear, step-by-step instructions to guide participants.

Promote Your Program

Spread the word about your referral program through these channels:

Highlight it prominently on your website.
Include details in post-purchase emails.
Add a mention in order confirmation messages.
Share customer success stories to inspire others to join.

A referral program works best when paired with great customer service and quality products. When customers genuinely love what you offer, they’re more likely to recommend your brand, reducing your customer acquisition costs even further.
