Shopify Tech Stack by Growth Stage: What 120,017 Stores Install at Every Traffic Tier

TL;DR from 120,017 Shopify stores across 5 growth stages:

• Stores in the 1M-5M visitor tier run 2.9 apps on average, nearly double the 1.5 apps at the starter level
• 69% of starter stores have no email marketing app. That drops to 43% by the scaling stage, but never reaches zero
• Paid themes peak at the growing stage (45% adoption), while custom themes dominate at enterprise (36%)
• The biggest jump in tech investment happens between the starter and growing stages: email adoption jumps 20 percentage points from 31% to 51%
• Even at the scaling stage, 66% of stores still have no reviews app and 80% have no customer support tool
• Klaviyo + Judge.me is the most common app pair at every growth stage

Every "best Shopify apps" article recommends the same 20 tools. They list features, pricing, and star ratings. Then they tell you to install all of them.

The problem: a store doing $2,000/month doesn't need the same stack as a store doing $200,000/month. A Rebuy subscription makes zero sense if you're getting 5,000 visitors a month. Advanced analytics from Elevar won't help if you're not running paid ads yet.

What nobody tells you is when to add each tool.

We have the data to answer that. We scanned 120,017 live Shopify stores and mapped their tech stacks to five traffic tiers. Instead of telling you what apps are "best," this post shows you what stores at your size actually use, what they skip, and where the biggest gaps are at every growth stage.

Whether you're building your own store or qualifying leads for your agency, this is the progression roadmap that doesn't exist anywhere else.

How We Collected This Data

Dataset: 120,017 Shopify stores in the StoreInspect database

Method: Frontend detection patterns identify apps, themes, and tracking pixels. Our scanner checks script signatures, JavaScript variables, DOM elements, and network requests for each store.

Growth stages (defined by monthly traffic):

*56 stores with unknown traffic tier excluded from stage assignment.

What we detect: Frontend apps (email marketing, reviews, support, upsell, analytics, loyalty, popups, subscriptions), 135 tracking pixels, themes, and Shopify Plus status. We cannot detect backend-only apps like inventory management, fulfillment, or accounting tools.

Shopify Plus: 70.8% of stores in our dataset are on Shopify Plus. Our sample skews toward established businesses, which makes the growth stage data more reliable for the mid-to-upper tiers.

Limitations: Frontend detection undercounts apps that run entirely server-side. The real app counts at every stage are likely higher. Pixel counts are more accurate since tracking scripts must load in the browser. Traffic tiers are estimated from multiple signals, not exact analytics data.

The 5 Growth Stages at a Glance

Here's the full picture before we break down each stage:

Three things stand out immediately:

1. The starter-to-growing jump is the biggest. Average app count increases 47% (1.5 to 2.2), pixel count increases 56% (3.4 to 5.3), and email adoption nearly doubles.
2. Growth plateaus after the established stage. App count, pixel count, and lead score all flatten between established and enterprise. Bigger stores don't keep piling on more tools. They add better tools.
3. Gaps never close. Even at the scaling stage with 1M+ monthly visitors, 43% of stores still have no email app and 66% have no reviews app.

---

Stage 1: Starter Stores (Under 50K Monthly Visitors)

52,281 stores | 1.5 avg apps | 3.4 avg pixels | Lead score: 55

Starter stores are the largest segment of the Shopify ecosystem. Most are new businesses, side projects, or early-stage brands still finding product-market fit.

What Starter Stores Actually Run

The pattern: Most starter stores run one app or none. 19% of all stores in our dataset have zero detected apps, and the majority of those are in this tier. The first app installed is almost always email marketing, specifically Klaviyo or Mailchimp.

What's Missing at the Starter Level

The gap data tells the real story. Seven out of ten starter stores have no email marketing at all. That means no abandoned cart recovery, no post-purchase sequences, no list building. For agencies pitching Shopify stores, this is the most common opportunity at the starter level: basic email setup.

Themes at the Starter Stage

Dawn and Debut dominate at this stage. Over 40% of starter stores use free themes, which makes sense. Early-stage stores are testing products and markets. A $350 premium theme isn't the priority. See our full theme analysis for the complete breakdown.

Starter Stage Summary

The typical starter store: Dawn theme, maybe Klaviyo or Mailchimp, Google Analytics, and the Meta Pixel. That's it. Minimal investment, maximum uncertainty about what works.

---

Stage 2: Growing Stores (50K-200K Monthly Visitors)

12,223 stores | 2.2 avg apps | 5.3 avg pixels | Lead score: 71

Growing stores have found something that works. They're getting consistent traffic, running paid ads, and starting to invest in their tech stack. This is where the first real tool decisions happen.

What Growing Stores Actually Run

The pattern: Email marketing adoption jumps 20 percentage points. Over half of growing stores now have an email app. Reviews adoption hits 26%, meaning roughly one in four growing stores has invested in social proof. Support tools triple from 4% to 10%.

This is the first stage where stores start building a real stack. The typical growing store has 2-3 apps: email + reviews, or email + loyalty.

The Most Common Growing Store Stacks

Based on our co-installation analysis, the most common app combinations at this level:

1. Klaviyo + Judge.me (email + reviews)
2. Klaviyo + Smile.io (email + loyalty)
3. Mailchimp + Privy (email + popups)
4. Klaviyo + Gorgias (email + support)

Klaviyo appears in three of the four most common pairings. This matches what we see in our email marketing app study: Klaviyo dominates among stores that take email seriously.

Themes at the Growing Stage

This is peak paid theme adoption. Nearly half of growing stores invest in premium themes like Prestige (3.8% market share), Impulse (3.7%), or Symmetry (1.7%). The logic is clear: once you have consistent traffic, converting that traffic better is worth $250-$400 for a theme upgrade.

Custom themes drop at this stage. Growing stores buy premium themes off the shelf. They don't yet have the revenue to justify a $5,000-$15,000 custom build.

Growing Stage Summary

The typical growing store: paid theme (Prestige or Impulse), Klaviyo, Judge.me or another reviews app, 5+ tracking pixels including Meta Pixel, Google Analytics, and Google Ads. This is the stage where stores go from "just launched" to "investing in growth."

---

Stage 3: Established Stores (200K-1M Monthly Visitors)

53,658 stores | 2.0 avg apps | 5.6 avg pixels | Lead score: 81

Established stores are the backbone of the Shopify ecosystem. They have real revenue, proven products, and steady traffic. Interestingly, their average app count (2.0) is slightly lower than growing stores (2.2).

What Established Stores Actually Run

The counterintuitive finding: Adoption rates for most app categories are slightly lower at the established stage than at the growing stage. This isn't a data error. It reflects the composition of this tier.

The 200K-1M range is the widest tier in our dataset. It includes both genuine DTC brands investing heavily and large-catalog commodity stores with high traffic but minimal marketing infrastructure. Some of these are established marketplaces or manufacturer-direct stores that drive traffic through organic search or wholesale channels, not through the email + reviews + paid ads stack.

What the Pixel Stack Reveals

Where the established stage really shows its maturity is in pixel sophistication. Average pixel count climbs to 5.6, matching the scaling tier. Our pixel detection study found that at this traffic level:

• Meta Pixel adoption exceeds 70%
• Google Ads reaches 65%+
• TikTok Pixel starts appearing at meaningful rates (10-14%)
• Pinterest and retargeting pixels emerge
• Hotjar or Microsoft Clarity for behavior analytics (combined ~12%)

Established stores may not all have fancy app stacks, but they track everything. Pixels are cheaper and easier to install than apps, so tracking sophistication outpaces app adoption at every stage.

Established Stage Summary

The typical established store: a mix of paid and free themes, Klaviyo (if they have email), a reviews app, and a mature pixel stack with 5-6 tracking scripts. The wide variance at this level makes it the hardest stage to generalize, and the most interesting for agencies looking to find stores with specific gaps.

---

Stage 4: Scaling Stores (1M-5M Monthly Visitors)

936 stores | 2.9 avg apps | 5.6 avg pixels | Lead score: 82

Scaling stores are doing real volume. At 1M+ monthly visitors, these are well-funded brands with dedicated marketing teams and serious ad budgets. This is where the full stack starts to emerge.

What Scaling Stores Actually Run

The pattern: Every category spikes at this stage. Support tools jump the most, from 7% to 20%. At this traffic level, brands can't handle customer service over email alone. Gorgias becomes essential.

Analytics jumps from under 2% to 11%. Scaling stores running six-figure ad budgets need attribution tools like Elevar to understand what's actually driving revenue. The "just check Google Analytics" approach breaks down at this spend level.

Upsell adoption hits 8.4%, the highest of any tier. When you have the traffic volume, even a small AOV increase compounds into serious revenue. Rebuy leads this category.

The Most Common App Trios (All Stores)

The co-installation patterns that dominate across the full dataset (not limited to scaling stores):

Klaviyo anchors every power stack. The second app reveals the store's priority: reviews for social proof, support for customer experience, loyalty for retention, or upsell for revenue optimization.

Theme Profile at the Scaling Stage

Custom themes start climbing back. At $1M+ monthly visitors, brands can justify a custom theme build for brand differentiation and conversion optimization. But paid themes still hold strong, and even 36% use free themes (often heavily customized Dawn builds with custom Liquid code).

Scaling Stage Summary

The typical scaling store: 3 apps (email + reviews/support + loyalty/upsell), a mature pixel stack, and increasingly custom themes. This is where stores graduate from "buying off the shelf" to "building a competitive moat" with their tech stack.

---

Stage 5: Enterprise Stores (5M+ Monthly Visitors)

863 stores | 2.8 avg apps | 5.4 avg pixels | Lead score: 81

Enterprise stores are the Gymshark, Fashion Nova, and Allbirds of the Shopify world. They process thousands of orders per day and run marketing operations that rival mid-size companies.

What Enterprise Stores Actually Run

The consolidation effect: App adoption rates dip slightly from the scaling stage. Enterprise stores don't add more tools. They add different ones.

The notable addition at this stage is personalization (5.3% vs 2.2% at scaling). Apps like Nosto and LimeSpot tailor product recommendations to individual visitors. At 5M+ visitors, even a 0.1% conversion rate improvement means thousands of additional orders.

Why Fewer Apps at the Top

Enterprise stores often consolidate their stack. Instead of running Klaviyo + a separate SMS tool + a separate popup tool, they'll use Klaviyo's built-in SMS and forms. Instead of Judge.me for basic reviews, they'll run Yotpo Reviews + Yotpo Loyalty as a unified platform.

This consolidation is invisible to frontend detection. A store using Klaviyo for email, SMS, forms, and flows registers as one app, not four. The actual functionality per store increases even as detected app count stays flat.

Theme Profile at Enterprise

Custom themes hit their peak. Over a third of enterprise stores run fully custom designs. At this scale, the investment in a custom theme ($10,000-$50,000+) is trivial relative to monthly revenue. Brand experience and conversion optimization justify every dollar.

Enterprise Stage Summary

The typical enterprise store: custom or premium theme, consolidated app stack centered on Klaviyo, enterprise-grade tools (Gorgias, Rebuy, Yotpo), personalization, and the most sophisticated pixel stack. Less quantity, more quality.

The Gap Map: What's Missing at Every Growth Stage

This is the data that makes agencies money. Here's the percentage of stores at each stage that are missing each tool category:

Read this table and think about what it means for anyone selling services to Shopify stores:

• Email marketing is the universal gap. Even at the scaling stage, 43% of stores generating millions of visitors per month have no detected email app. For Klaviyo agencies, this is a pipeline that never dries up.
• Reviews are the most under-adopted CRO tool. Two-thirds of scaling stores have no reviews. That's a conversion rate gap you can quantify: stores with review apps have demonstrably more sophisticated marketing stacks.
• Support tools barely exist outside the top tier. 80%+ of stores at every stage handle customer support through basic email. Gorgias consultants have a wide open market.
• Upsell and analytics are "advanced" tools even for enterprise. Over 90% of stores at every stage skip these categories entirely.

For a deeper breakdown of how to turn these gaps into outreach, see our cold email templates for Shopify stores.

---

When to Add What: A Data-Backed Timeline

Based on adoption patterns across 120,017 stores, here's when each tool category reaches meaningful adoption:

This isn't prescriptive advice. It's what 120,017 real stores have done. If your store is at the growing stage and you don't have email marketing, you're in the minority. If you're a starter store without analytics tools, you're in the majority.

---

How Themes Change With Growth

Theme choice tells a story about a store's priorities and budget:

The three-act theme journey:

1. Act 1 (Starter): Use Dawn or another free theme. Focus on product and messaging, not design.
2. Act 2 (Growing through Established): Upgrade to a paid theme like Prestige, Impulse, or Broadcast. The $250-$400 investment improves conversion without custom development costs.
3. Act 3 (Scaling through Enterprise): Build custom or heavily customize. At $1M+ traffic, the ROI on a $10,000+ custom theme is measurable in conversion rate improvements.

The data backs this up. Paid theme stores run more apps across the board. Our theme analysis found that paid theme stores are 1.8x more likely to use email marketing and 1.9x more likely to have a reviews app than free theme stores.

Paid theme stores are the most app-invested segment. This isn't because the theme makes them install apps. It's because the same stores that invest $350 in a theme also invest in email, reviews, and support. Theme choice is a proxy for marketing maturity.

For agencies, this is a qualifying signal. A store on Dawn with no apps is at a different stage than a store on Prestige with Klaviyo installed. See our lead qualification guide for how to use these signals in outreach.

How Pixel Stacks Evolve With Growth

Pixel adoption tells you about a store's advertising sophistication. Our pixel detection study covers this in depth, but here's how it maps to growth stages:

Pixel Count by Stage

Key Pixel Milestones

Based on adoption data from our competitor analysis:

The pixel progression mirrors the growth journey: first you track (GA4), then you advertise (Meta + Google Ads), then you diversify (TikTok + Pinterest), then you optimize (Hotjar/Clarity), then you consolidate (server-side tracking, fewer but better-integrated pixels).

---

Shopify Plus Adoption by Growth Stage

Shopify Plus is a strong proxy for store maturity and budget. In our dataset:

Plus stores run 2.75x more apps and 3.5x more pixels than standard stores. They also carry 2.3x more products. This isn't just about the platform fee ($2,300/mo for Plus). It reflects a fundamental difference in how these businesses invest in growth.

For agencies and SaaS companies, Plus status is one of the strongest qualifying signals for outbound prospecting. A Plus store on a free theme with no reviews app is a better lead than a standard store with the full stack, because the Plus store has demonstrated budget allocation capacity.

---

What This Means for Agencies and SaaS Companies

This data has direct implications for anyone selling to Shopify stores:

If You Sell Email Marketing Services

Your total addressable market at the growing stage is 49% of stores, roughly 6,000 stores in our dataset at the 50K-200K tier alone with no email app. The pitch writes itself: "You're getting 100K monthly visitors with no email capture. Here's what that costs you."

Filter by growing-stage stores without Klaviyo in the StoreInspect dashboard to build a targeted outreach list.

If You Sell Review App Setup

74% of growing stores and 75% of established stores have no reviews app. That's over 49,000 stores in those two tiers missing social proof. Lead with data: "Stores in your traffic tier with reviews apps have demonstrably higher lead fit scores."

If You're a Shopify Plus Agency

Target established stores (200K-1M) on standard Shopify with sophisticated app stacks. These are the stores ready to upgrade to Plus but haven't yet. Their tech maturity signals readiness even if they haven't crossed the Plus threshold.

If You Build Shopify Apps

The gap map is your market sizing tool. If you build upsell apps, your addressable market is 92-99% of stores at every tier. If you build loyalty apps, it's 86-95%. The question isn't "is there a market?" It's "which tier is most likely to buy?"

For bulk prospecting based on tech stack gaps, StoreInspect lets you filter 120,000+ stores by app presence, traffic tier, category, and contact availability.

How Niches Differ: Tech Stack by Industry

Growth stage isn't the only factor. Industry matters too. Here are the most and least tech-invested verticals:

Beauty stores lead in app investment (2.4 avg), driven by high Klaviyo adoption (38%) and review app usage (26%). Beauty is a category where social proof, email marketing, and loyalty programs directly drive repeat purchases.

Hobby stores are the least invested (1.5 avg apps, 63% Plus). Many hobby stores are passion projects rather than full-time businesses, which shows in their tech stack.

Fashion is interesting: it's the largest category by far (30,002 stores) but only average in tech investment. The sheer number of early-stage fashion stores dilutes the average. High-traffic fashion stores like Gymshark and Fashion Nova run sophisticated stacks, but they're outnumbered by the long tail of small fashion shops.

For the complete niche analysis with top apps per category, see our best Shopify niches study.

App Stack Complexity: How Many Apps Is Normal?

One of the most common questions we hear: "How many apps should I have?" Here's what the data says:

The correlation is clear: More apps = higher lead scores = more pixels. Stores with 3-5 detected apps average a lead score of 89 (out of 100) and 6.6 pixels. These are the stores actively investing in growth.

But note the distribution: 73% of stores run 0-2 apps. Only 2.7% run 6 or more. The "install 20 apps" advice you see in blog posts doesn't match reality. Most stores run a minimal stack.

Our tech stack overview has the full breakdown of what those apps are at each complexity level.

---

How many apps should a Shopify store have?

Based on 120,017 stores, the sweet spot is 2-5 detected apps. Stores with 3-5 apps average a lead score of 89 and run 6.6 pixels, indicating mature marketing operations. The average across all stores is 1.8 apps. However, frontend detection undercounts total apps since backend-only tools aren't visible. The real number at each stage is likely 1.5-2x higher.

What's the first app a Shopify store should install?

Email marketing. It's the first category to reach meaningful adoption (31% even at the starter level) and the app with the clearest ROI. Klaviyo leads at 25.8% overall adoption, followed by Mailchimp at 14.1%. Abandoned cart recovery alone typically generates 3-5% additional revenue. See our email marketing app comparison for the full breakdown.

When should a Shopify store add a reviews app?

Once you have consistent traffic. Reviews adoption jumps from 17% at the starter level to 26% at the growing stage (50K+ monthly visitors). Judge.me is the most popular choice across all tiers because of its free plan. Yotpo becomes more common among scaling stores with bigger budgets. See our review app comparison for details.

When should I upgrade to a paid Shopify theme?

Paid theme adoption peaks at the growing stage (45% of stores with 50K-200K monthly visitors). If you have consistent traffic and your conversion rate matters, a $250-$400 paid theme like Prestige or Impulse is one of the highest-ROI investments. Free themes work fine for testing products and markets.

Do more apps slow down a Shopify store?

Each app adds JavaScript to your storefront, which can impact load times. But the data shows that higher-traffic stores run more apps, not fewer. The key is choosing apps that justify their performance cost. Enterprise stores consolidate (2.8 apps) rather than accumulate, using platforms like Klaviyo that combine email, SMS, and forms in a single script.

What pixels should a Shopify store have?

At minimum: Google Analytics 4 and the Meta Pixel. These are nearly universal among established stores. Add Google Ads when you start running paid search. TikTok Pixel and Pinterest if you advertise on those platforms. Behavior analytics tools like Hotjar or Clarity when you're ready to optimize conversion. See our full pixel study.

When should a Shopify store switch to Shopify Plus?

Our data shows Plus stores average 2.2 apps vs 0.8 for standard, with 3.5x more pixels. Plus starts at $2,300/month, so it makes sense when your revenue justifies the cost (typically $400K+/month). Use tech stack sophistication as a readiness signal: if a standard store has 3+ apps, a paid theme, and 5+ pixels, they're likely a Plus candidate. Our Plus identification guide covers the detection methods.

What's the most common Shopify app combination?

Klaviyo + Judge.me is the most common pair, found in 4,042 stores (3.4% of all stores). The most common trio is Klaviyo + Judge.me + Shop Pay at 3,348 stores. Klaviyo anchors every top combination because email marketing is the first serious tool most stores adopt.

How do I benchmark my Shopify store's tech stack?

Compare your store against others at the same traffic tier using the tables in this post. Or use the StoreInspect dashboard to filter stores by your traffic level and category, then compare app adoption rates. Our audit framework provides a structured T.A.P.S. methodology for evaluating any store.

Which Shopify niche invests the most in apps?

Beauty leads at 2.4 average apps per store, with 80% Shopify Plus adoption and 38% Klaviyo usage. Baby & Kids (2.2 avg) and Health & Wellness (2.1 avg) follow closely. These categories have high repeat purchase rates, which justifies investment in email, loyalty, and review tools. See our niche analysis.

How can agencies use this growth stage data for prospecting?

Identify stores at the wrong stage for their traffic. A growing store (50K-200K visitors) with no email app is a qualified lead for a Klaviyo agency. A scaling store (1M+) on a free theme is a qualified lead for a Shopify design agency. Use StoreInspect to filter by traffic tier, missing apps, and category to build targeted outreach lists.
