The 2025 Shopify Growth Stack: 16 Must-Have Apps for Traffic, Conversions & Retention
Seeing tangible growth for your Shopify store is so much more than running ads. In fact, ads are not what they used to be - just ask around. It’s about creating a seamless tech stack that drives traffic and converts visitors. Plus the right people to work with, but that's a story for another day.
Ok, we’re halfway through 2025, but the title still holds, right? Scaling your Shopify store nowadays means more than just launching ads. In fact, ads are getting tougher to find the sweet spot for. Instead, it’s about creating a seamless tech stack that drives traffic, converts visitors, and maximizes customer lifetime value. And all this, while keeping your operations nice and clean.
There are basically thousands of apps on Shopify’s App Store, so it’s hard to know where to start. But a solid start does count, so here we are.
We have pulled together 6 essential app categories that every ambitious Merchant needs to build a thriving, future-proof business. The first one is in its league (sic!) of its own, while for the rest, we’re giving the best options we could think of.
Affiliate Marketing: BusinessLeague.com.
Why it’s essential
Affiliate marketing is the ultimate way to grow your number of sales without upfront ad spend. Yup, zero. By empowering Affiliates to promote your brand using their own resources, you only pay for results. No real risk, just the willingness to learn how to navigate one platform or another.
And by the way, some of these Affiliates are experts in certain categories of products (Books, Fashion, etc), including yours, most likely.
Why it’s useful:
- You set up a campaign in minutes
- You get access to the best Marketers out there who use their own budgets to promote your products
- You only pay them a percentage for sales made. Only when orders are confirmed.
- You get the full support of the BusinessLeague crew
- It’s all transparent, so you get to see your competitors’ stats as well
- Win bonuses through constant Challenges on the platform
- You’re part of the only affiliate competition in the world, where you can win prizes and so much more.
Email & SMS Marketing Automation
Why it’s essential
Email and SMS are your owned channels. They drive repeat purchases, recover abandoned carts, and build long-term customer relationships – all at a fraction of the cost of paid ads.
Top tools to consider
- Klaviyo – Powerful segmentation & predictive analytics
- Omnisend – Easy multi-channel workflows (email, SMS, push)
- Attentive – Best-in-class SMS with personalized automations
Pro tip: Coordinate your affiliate campaigns with email and SMS flows. Promote your top affiliates’ special deals, or send “as seen on Instagram” highlights to capitalize on social buzz.
Conversion Rate Optimization (CRO) Tools
Why it’s essential
More traffic is great, but without CRO tools, you’re leaving money on the table. Optimize your store to turn more visitors into paying customers.
Popular apps to explore
- Fomo – Real-time popups showing what others are buying (social proof)
- Optimizely – Advanced A/B testing for headlines, images, and layouts
- Lucky Orange – Heatmaps & session replays to understand shopper behavior
Small tweaks, like simplifying your checkout or testing urgency timers, can deliver huge lifts in conversion.
Subscription & Loyalty Programs
Why it’s essential
The cost of acquiring customers keeps rising. Subscriptions and loyalty programs drive predictable, recurring revenue and turn first-time buyers into lifelong fans.
Best-in-class options
- Recharge – Manage subscriptions, build bundles, reduce churn
- Smile.io – Reward programs, VIP tiers, referral incentives
- LoyaltyLion – Deep analytics plus robust loyalty campaigns
These sorts of tools are commonly used by top Marketers/Affiliates to bring in new customers for e-shops.
Reviews & Social Proof
Why it’s essential
93% of shoppers read reviews before buying. Reviews build trust and can dramatically increase conversion rates, especially for newer stores.
Leading apps to install
- Judge.me – Affordable, fast-loading reviews with photo & video support
- Yotpo – Premium UGC (user-generated content) and loyalty integrations
- Loox – Visual reviews that showcase customer photos
Analytics & Business Intelligence Dashboards
Why it’s essential
To scale smart, you need to know exactly what’s driving sales, which channels, which affiliates, and which products. Advanced analytics go beyond Shopify’s built-in reports to give you actionable insights.
Power analytics tools
- Glew.io – Unifies e-commerce, marketing, and customer data
- Triple Whale – Attribution plus customer lifetime value (LTV) dashboards
- Looker Studio + Segment – For merchants wanting fully custom BI
Pair these insights with your affiliate platform (like BusinessLeague.com, which already gives you great stats) to double down on your best-performing partnerships.
