Why Your Shopify Store May Need a Custom App?

Standard Shopify features and public apps often lack the necessary functionality to sell your business. However, a Shopify custom app enables you to: 

  • Synergize with third-party services like ERP, CRM, or marketing automation. 
  • Automate workflows such as custom checkout rules, discount scripts, or inventory management 
  • Collect and analyze data that exceeds the standard Shopify reports. 
  • Create a smooth, branded experience for customers and staff. 

A custom app helps your store align with your exact business model, boosting efficiency, conversions, and user experience.

Webspirit Agency’s Checklist: How to Improve Conversion on Your Shopify Plus Website

Conversion Rate Optimization (CRO) is at the heart of every high-performing Shopify store. Here’s our Shopify CRO framework that helps clients boost sales by up to 50%.

Get Started!

Technical Optimization

The foundation of every high-performing website.

Make sure your store runs fast and flawlessly on every device.

Checkpoints:

  • Fast page loading (under 2 seconds)
  • No broken links or missing images
  • Optimized high-quality visuals
  • Responsive layout for desktop, tablet, and mobile
  • Compressed scripts and images for speed

Tip: Use tools like Google PageSpeed Insights, and Shopify Analyzer to spot issues before they affect conversions.

Analytics

You can’t improve what you can’t measure.

Track every click, scroll, and purchase to understand how users interact with your store.

Checkpoints:

  • Install Google Analytics 4 (GA4) for data tracking
  • Connect Google Tag Manager (GTM) for event tracking
  • Add Hotjar or Microsoft Clarity (free forever) for heatmaps and session recordings
  • Track key funnels: product views → add to cart → checkout → order completion

Tip: Review analytics weekly to find friction points in your checkout or navigation flow.

Optimize Product Pages for Conversions

Your product page is where customers make their final decision — make it count.

Checkpoints:

  • Clean layout with high-quality images and zoom
  • Clear product title, price, and sizes/measurements
  • Add urgency and trust elements:
    • Countdown timers (“Offer ends soon”)
    • Low-stock alerts (“Only 3 left in stock”)
    • Social proof or review widgets
  • Add bundle builders and “Complete the Look” recommendations
  • Showcase shipping info, return policy, and trust badges

Tip: Test your layout regularly — even small design tweaks can increase conversions by 10–20%.

Smooth Checkout Process

Make the path from product to purchase as frictionless as possible.

Checkpoints:

  • Minimize checkout steps (avoid multi-page flows)
  • Ask for only essential information
  • Offer multiple payment options (Shop Pay, Apple Pay, PayPal, credit card)
  • Display order summary and shipping cost upfront
  • Add trust signals like SSL, badges, and refund guarantees

Tip: Shopify’s native one-page checkout already converts better than most platforms — keep it simple and distraction-free

On-Page and Off-Page SEO

Make your store discoverable and trustworthy.

On-Page SEO:

  • Optimize titles, meta descriptions, and headings (H1–H3)
  • Use long-tail keywords related to your products
  • Compress images and include descriptive alt text
  • Build internal links between products and collections

Off-Page SEO:

  • Get backlinks from guest posts, directories, or influencer mentions
  • Maintain Google Business Profile if applicable
  • Collect authentic customer reviews to build domain trust

Tip: SEO and CRO work hand-in-hand — the traffic you attract should convert easily once it lands on your site.

Personalization and A/B Testing

Data-driven personalization builds stronger engagement and higher conversions.

Your customers are not all the same — personalize their journey based on behavior, location, or interests.

Checkpoints:

  • Use Shopify Flow or Shopify Scripts to personalize discounts, banners, or messages (e.g., “Welcome back!” or “Free shipping for California orders”).
  • Set up A/B tests for product images, CTAs, headlines, and banners to discover which versions convert best.
  • Segment visitors by traffic source or returning users to tailor homepage offers or popups.
  • Offer personalized product recommendations using browsing history or order data.
  • Display local currency, language, and delivery info dynamically.

Tip: Use tools like Google Optimize, Optimizely, or ConvertFlow for experiments and Shopify’s native customer segments to personalize experience — continuous testing leads to compounding conversion gains.

Email, Retention, and Post-Purchase Optimization

Your job doesn’t end when a customer buys — it starts there.

Retention-focused CRO ensures buyers become repeat customers.

Checkpoints:

  • Implement automated post-purchase flows (thank-you email, review request, product-care tips).
  • Send abandoned cart reminders within 1–3 hours of drop-off.
  • Create personalized email campaigns for bestsellers, new drops, and exclusive offers.
  • Offer loyalty points or referral discounts for returning customers.
  • Use dynamic cross-sell emails (“Complete your set” or “You may also like”).
  • Optimize email templates for mobile — over 70% of users check email on their phones.

Tip: Use Klaviyo, Omnisend, or Brevo for automated flows and tracking. Email-based CRO can increase lifetime value (LTV) by up to 30% with minimal extra ad spend.
