Best Shopify Spy Tools in 2026 [Honest Guide + 4,898-Store Data]
We compared 10 Shopify spy tools and analyzed 4,898 stores to find what actually works. Honest accuracy expectations, real user ratings, and the signals that matter.
Learn 7 ways to estimate any Shopify store's revenue. Original data from 4,898 stores reveals which signals actually predict revenue. Free methods included.

TL;DR: You can't check exact Shopify store revenue - but you can estimate it. We analyzed 4,898 stores and found that stores with 1M+ monthly visitors average 4.4 apps vs 2.2 for stores under 10k. Traffic tier is your best signal. Use a Shopify store database to filter by revenue signals, or check any store's tech stack with the free Store Inspector extension.
You want to check Shopify store revenue. Maybe you're researching a competitor. Maybe you're thinking about buying a store. Maybe you're an agency looking for good leads.
Here's the truth: you can't see exact revenue numbers for any Shopify store (unless they're public or tell you directly).
But you can get estimates. Some methods work well. Others are useless. This guide covers seven ways to estimate Shopify store revenue - ranked by how well they work - plus real data from 4,898 stores that shows which signals actually match up with revenue.
We're going to be honest about accuracy. Most guides claim "70-85% accuracy" with no proof. Real accuracy is closer to 50-70% for most methods, and we'll explain why.
Before diving into methods, here's why people estimate competitor revenue:
| Use Case | What You Need |
|---|---|
| Competitor benchmarking | Understand market size and your position |
| Acquisition research | Validate asking price before buying |
| Partnership evaluation | Assess potential collaborators |
| Lead qualification | Prioritize high-value prospects |
| Market research | Size opportunities in a niche |
The method you choose depends on your goal. Quick competitor check? Traffic estimation is fine. Buying a store? You need to cross-check multiple methods.
Every revenue guide uses some version of this formula:
Monthly Revenue = Traffic × Conversion Rate × Average Order Value
Example: 50,000 visitors × 2% conversion × $80 average order = $80,000/month
Sounds simple. But this formula has serious problems:
The formula gives you a starting point. But don't treat it as accurate.
What we'll show you: How to cross-check estimates using multiple signals - tech stack, social proof, and real data from nearly 5,000 stores.
Accuracy: 40-60% | Cost: Free-$100/mo | Best for: Quick competitor checks
The most common method. Estimate traffic, apply conversion benchmarks, guess AOV.
How to do it:
Conversion rate benchmarks by category:
| Category | Avg CVR | Notes |
|---|---|---|
| Gifts & Occasions | 4.9% | High intent, seasonal |
| Health & Wellness | 3.4% | Repeat buyers, subscriptions |
| Food & Beverage | 2.4% | Consumables drive loyalty |
| Beauty & Cosmetics | 2.2% | High competition |
| Fashion & Apparel | 1.5% | Browsers > buyers |
| Electronics | 1.4% | High research, price shopping |
| Home & Garden | 1.3% | Considered purchases |
| Jewelry | 1.2% | High AOV, low CVR |

Example calculation:
A fashion store shows 100,000 monthly visitors on SimilarWeb. You check their catalog and see products averaging $65.
100,000 × 1.5% × $65 = $97,500/month
Why this method fails:
When to use it: Quick rough estimates. Comparing competitors to each other (who's bigger?) rather than exact numbers.
Accuracy: 50-70% | Cost: Free | Best for: Checking traffic estimates
This is where we have data no one else has. We analyzed 4,898 Shopify stores and found clear links between tech stack and traffic tier - which connects to revenue.
The insight: Stores buy more apps and tools as they grow. A store running Klaviyo + Gorgias + Rebuy + Elevar isn't doing $10k/month. That stack costs $500+/month minimum. They wouldn't pay for it unless they had the revenue.
For a deeper dive on tech stacks, see our analysis of what apps top Shopify stores use.
App count by traffic tier (4,898 stores):
| Traffic Tier | Avg Apps | Avg Pixels | Revenue Range |
|---|---|---|---|
| Under 10k | 2.2 | 4.3 | $0-$50k/month |
| 10k-50k | 3.0 | 5.7 | $50k-$250k/month |
| 50k-200k | 3.8 | 6.0 | $250k-$1M/month |
| 200k-500k | 3.6 | 5.8 | $1M-$3M/month |
| 500k-1M | 3.6 | 5.6 | $3M-$5M/month |
| 1M-5M | 4.4 | 6.1 | $5M+/month |
Revenue signals by specific app:
| App/Tool | What It Signals | Minimum Revenue |
|---|---|---|
| Klaviyo | Serious email program | $20k+/month |
| Gorgias | Dedicated support | $50k+/month |
| Rebuy | AOV optimization | $100k+/month |
| Elevar | Server-side tracking | $100k+/month |
| Northbeam | Advanced attribution | $200k+/month |
| Recharge | Subscriptions | Varies |
| Shopify Plus | Enterprise features | $500k+/month typical |
How to check a store's tech stack:
Example: A store running Klaviyo (email), Gorgias (support), Rebuy (upsells), Judge.me (reviews), and Elevar (tracking) = 5 apps. That puts them in the 50k-200k traffic tier, suggesting $250k-$1M/month revenue.
Real example: We looked at Gymshark. They run Klaviyo, Gorgias, Rebuy, Yotpo, Attentive, and several analytics tools - 7+ apps visible. That matches their 1M+ traffic tier. No surprise they're doing $500M+/year.
Why this works: Stores don't pay $300-$500/month for apps unless they have the revenue to justify it. Tech spending grows with business size.
Pixel count shows ad spend:
We also found that pixel count connects to ad budget:
| Pixels | Signal |
|---|---|
| 1-3 pixels | Minimal paid ads |
| 4-5 pixels | Active on 1-2 platforms |
| 6+ pixels | Diversified ad strategy, real budget |
| Meta + TikTok + Pinterest | DTC brand investing across platforms |
A store with Meta Pixel, TikTok Pixel, Google Ads, Pinterest Tag, AND Snapchat Pixel is spending serious money on ads. That means serious revenue.
Accuracy: 30-50% | Cost: Free | Best for: Product-level estimates
Reviews can reveal sales volume - but only roughly. The idea: if you know what percent of buyers leave reviews, you can estimate total sales.
The formula:
Estimated Sales = Review Count ÷ Review Rate
Typical review rates:
| Scenario | Review Rate |
|---|---|
| No review requests | 1-2% |
| Basic review emails | 2-3% |
| Aggressive review program (Judge.me, Yotpo) | 3-5% |
| Incentivized reviews | 5-8% |
Example: A product has 500 reviews. Assuming a 2% review rate:
500 reviews ÷ 2% = 25,000 sales
If the product is $50, that's $1.25M in revenue from that single product.
Problems with this method:
When it's useful: Estimating relative product performance (which products sell best) rather than absolute numbers. Works better for stores under 2-3 years old.
Accuracy: 30-50% | Cost: Free | Best for: Direct-to-consumer brands
Social following and ad activity show marketing budget - which connects to revenue. Big ad spend usually means big revenue.
Social following benchmarks:
| Instagram Followers | Typical Revenue |
|---|---|
| Under 10k | Early stage, under $50k/month |
| 10k-50k | Growing, $50k-$200k/month |
| 50k-200k | Established, $200k-$500k/month |
| 200k-1M | Scaled, $500k-$2M/month |
| 1M+ | Major brand, $2M+/month |
These are rough correlations, not guarantees. Follower counts can be bought.
How to check ad activity:
What to look for:
| Signal | What It Means |
|---|---|
| 50+ active ad creatives | Serious testing budget ($50k+/month spend) |
| Ads running 6+ months | Profitable campaigns, sustainable revenue |
| Multiple ad formats | Diversified strategy, real team |
| UGC + polished creative mix | Mature marketing operation |
Red flags:
Accuracy: 30-40% | Cost: Free | Best for: Filtering out new stores
Older stores with large catalogs typically have more revenue. Simple, but useful for quick filtering.
How to check store age:
Catalog signals:
| Metric | Signal |
|---|---|
| 10-50 products | Small/niche operation |
| 50-200 products | Growing catalog |
| 200-500 products | Established operation |
| 500+ products | Mature business or marketplace |
| 20+ collections | Organized, scaled operation |
Combined with age:
Accuracy: 50-70% | Cost: Free-$100/mo | Best for: Quick estimates at scale
Several tools specifically estimate Shopify store revenue. Here's an honest comparison:
| Tool | Price | Data Source | Pros | Cons |
|---|---|---|---|---|
| StoreCensus | Free tier + paid | Traffic, apps, pricing | 2M+ store database, methodology transparency | Claims 70-85% accuracy (unvalidated) |
| ZIK Analytics | $29-$99/mo | Traffic, product data | Daily updates, product-level data | Primarily designed for dropshipping |
| Koala Inspector | $9.99/mo | Traffic, store analysis | Easy Chrome extension | Revenue estimates are rough |
| WinningHunter | $49-$99/mo | Ad + store data | Good for ad research | Revenue is secondary feature |
| PPSPY | $29-$99/mo | Traffic, sales | Large database | User complaints about data accuracy |
| SimilarWeb | Free tier + enterprise | Traffic analytics | Industry standard for traffic | No direct revenue estimates |
Our take: Use these tools for rough estimates and filtering leads. Don't trust any single tool's number. Cross-check with other methods.
Our approach: StoreInspect combines tech stack data with traffic tiers for 4,898+ stores. Filter by category, apps, and revenue signals - then export with verified contacts. Or use the free Store Inspector extension to check individual stores.
Accuracy: 30-40% | Cost: Free-$100/mo | Best for: Content-heavy stores
SEO investment signals marketing budget, which correlates with revenue.
How to check:
Domain rating benchmarks:
| Ahrefs DR | Typical Investment | Revenue Signal |
|---|---|---|
| Under 20 | Minimal SEO | Early stage |
| 20-40 | Some content investment | Growing |
| 40-60 | Dedicated SEO program | $200k+/month |
| 60+ | Major content operation | $500k+/month |
What to look for:
Limitation: This only works for stores investing in SEO. Many DTC brands ignore SEO entirely and rely on paid ads. Low DR doesn't mean low revenue.
Based on our analysis of 4,898 Shopify stores, here's what each traffic tier typically means for revenue:
| Traffic Tier | Stores in Our Data | Revenue Range | Decision Maker | Sales Cycle |
|---|---|---|---|---|
| Under 10k | 1,503 (31%) | $0-$50k/month | Founder | Days |
| 10k-50k | 866 (18%) | $50k-$250k/month | Founder + 1 hire | 1-2 weeks |
| 50k-200k | 264 (5%) | $250k-$1M/month | Small team | 2-4 weeks |
| 200k-500k | 409 (8%) | $1M-$3M/month | Department heads | 1-2 months |
| 500k-1M | 719 (15%) | $3M-$5M/month | Multiple stakeholders | 2-3 months |
| 1M-5M | 856 (17%) | $5M-$15M/month | Committees | 3+ months |
| 5M+ | 28 (1%) | $15M+/month | Enterprise process | 6+ months |
Key insight for agencies: The 10k-50k traffic tier is the sweet spot. These stores have budget ($50k-$250k/month revenue) but founders still make fast decisions. Our data shows they average 3.0 apps - plenty of room to grow their stack. Learn more in our guide on how to find Shopify stores for lead generation.
Validation signals by tier:
| Tier | Look For | Red Flags |
|---|---|---|
| Under 10k | Basic setup, founder energy | Claims of high revenue |
| 10k-50k | Klaviyo, 1-2 support tools | No email marketing |
| 50k-200k | Gorgias, Rebuy, analytics tools | Still on Mailchimp |
| 200k+ | Full stack, multiple pixels | Outdated theme, few apps |
Different categories have different revenue patterns. Here's what our data shows:
| Category | Stores | Avg Apps | Avg CVR | Revenue Pattern |
|---|---|---|---|---|
| Health | 26 | 4.1 | 3.4% | High LTV, subscriptions |
| Kids | 31 | 3.8 | 2.8% | Seasonal spikes |
| Outdoor | 27 | 3.7 | 2.2% | Seasonal, high AOV |
| Home | 34 | 3.6 | 1.3% | Considered purchases |
| Sports | 47 | 3.5 | 2.0% | Passionate buyers |
| Food | 57 | 3.4 | 2.4% | Repeat purchases |
| Beauty | 39 | 3.2 | 2.2% | High competition |
| Fashion | 80 | 2.9 | 1.5% | Brand-driven |
| Electronics | 33 | 2.8 | 1.4% | Price-sensitive |
| Jewelry | 21 | 2.4 | 1.2% | High AOV, low CVR |
What this means for estimates:
When estimating revenue, adjust for category. A fashion store at 100k traffic will likely convert at 1.5%. A health store at 100k traffic might convert at 3.4% - more than double the revenue.
Health and Kids stores invest the most in their tech stack (4.1 and 3.8 apps respectively). These categories rely on retention and subscriptions.
Fashion stores invest less despite being the largest category. They rely more on brand and social media than apps.
Let's be honest about accuracy. Every method has significant limitations.
| Method | Best Case | Typical Case | Worst Case |
|---|---|---|---|
| Traffic × CVR × AOV | ±30% | ±50% | ±80% |
| Tech stack analysis | ±40% | ±50% | ±70% |
| Review count | ±40% | ±60% | ±90% |
| Social signals | ±50% | ±70% | ±100% |
| Revenue tools | ±30% | ±50% | ±70% |
Best case: Multiple signals agree. Traffic estimate, tech stack, and social presence all point to the same range. You can feel confident.
Typical case: Methods give you a range. A store might be anywhere from $100k to $300k/month. You know the ballpark, not the exact number.
Worst case: Limited data, weird business model, or brand new store. Your estimate could be 2x off in either direction. Proceed with caution.
These store types break the usual patterns:
Can I see exact revenue for any Shopify store?
No. Shopify doesn't expose store revenue publicly. You can only estimate based on traffic, tech stack, and other signals. The only way to get exact numbers is if the store is public (SEC filings), they share it themselves, or you have direct access to their analytics.
How accurate is SimilarWeb for Shopify stores?
SimilarWeb is reasonably accurate for stores with 100k+ monthly visitors (typically within 30%). For smaller stores, accuracy drops significantly - estimates can be 50-70% off. Always treat SimilarWeb numbers as directional, not precise.
What's the average Shopify store revenue?
Industry data varies widely. Backlinko reports average annual revenue of $72,000. Median is closer to $24,000 (most stores make less than average). The top 10% of stores make $100k+/month.
Why do app count and revenue correlate?
Stores invest in apps as they grow. A store doing $10k/month won't pay $500/month for Gorgias + Rebuy + Elevar. The tech stack reflects what the business can afford and needs. More apps = more operational complexity = more revenue to justify it.
Is checking competitor revenue legal?
Yes. You're using publicly available information (traffic estimates, visible tech stack, social profiles). You're not accessing private data. This is standard competitive intelligence.
Which free method is most reliable?
Tech stack analysis. Check a store's apps and pixels, then match against our traffic tier tables above. The app/pixel count connects reliably with traffic and revenue based on our data from 4,898 stores.
How do I check my own store's revenue?
In Shopify Admin: Analytics → Reports → Sales by channel/time period. You have exact data - no estimation needed. Use this for benchmarking against the category averages above.
What's the most common mistake in revenue estimation?
Using one method and treating it as fact. The traffic formula gives you a number, but it could easily be 50% off. Always cross-check with tech stack, social signals, and other sources.
Here's how to estimate Shopify store revenue:
| Method | Accuracy | Cost | Best For |

| Traffic estimation | 40-60% | Free-$100/mo | Quick checks |
| Tech stack analysis | 50-70% | Free | Cross-checking estimates |
| Review count | 30-50% | Free | Product-level |
| Social/ad signals | 30-50% | Free | Direct-to-consumer brands |
| Revenue tools | 50-70% | $29-$99/mo | Research at scale |
| SEO/DR analysis | 30-40% | Free-$100/mo | Content-heavy stores |
Our recommended approach:
