We looked at every app, pixel, and payment tool running on 1,041 established Shopify storefronts. The typical brand runs 9 apps — but the software a store adds as it scales tells you more about its revenue than almost anything on the page.
Tech-stack size scales cleanly with estimated revenue. Shopify stores estimated under $100K/year run an average of 2.1 apps; stores estimated at $10M+/year run an average of 10.8 — more than five times as many.
The gradient is monotonic across every band we measured: more revenue, more software, with no plateau in sight. A brand's app count is one of the cleanest revenue tells in the storefront.

Google Analytics leads every install, on 80.2% of stores, followed by Google Ads (74.3%) and the Meta Pixel (70.9%). Advertising and measurement are effectively table stakes.
The first non-Google, non-Meta tool on the list is Klaviyo, running on 58.4% of all stores — and on 92% of stores that run any dedicated email platform. No other category has a leader that dominant.
PayPal (56.2%) is the most common payment method after Shopify's own checkout, and Microsoft Clarity (41.5%) has quietly become the second-most-common analytics tool.
In four of the highest-value categories, a single app captures somewhere between a third and nearly all of every store that runs one. These are the defaults merchants reach for first.
Comparing $10M+/year stores against $1M–$10M/year stores, advertising (90% vs 85%) and product reviews (69% vs 71%) are adopted early and almost equally. They don't separate the winners.
The retention and lifecycle stack does. $10M+ stores are 3.2× more likely to run SMS marketing (19.6% vs 6.1%), 3.4× more likely to run a loyalty program (18.0% vs 5.3%), and 2.6× more likely to run a dedicated helpdesk (30.1% vs 11.5%) than mid-market stores.
The pattern is consistent: brands buy acquisition software to get off the ground, then layer on retention software to grow past the mid-market.
Across our sample, 83.8% of enriched stores estimate at $10M+/year, so any single app's baseline odds of belonging to a large brand are about 84.1%. These tools blow past that baseline — when you see them, you're almost certainly looking at a scaled brand:
% = share of each app's users that estimate at $10M+/year. Apps shown have ≥30 users in the sample.
82.5% of storefronts run both an analytics tool and an advertising pixel — 859 of 1,041 stores. It is the single most common pairing in ecommerce, and the foundation nearly every larger stack is built on.
Add product reviews and you have the most common full stack outright: Ads + Analytics + Reviews. Email and payments come next as stores mature.
A store's Shopify plan is only detectable from the public storefront for about 11% of our sample (115 of 1,041stores expose the checkout-extensibility markers that reveal it).
Among those, 95.7% are on Shopify Plus. The markers that leak a plan are the same enterprise features that Plus unlocks — so a detectable plan is itself a strong signal a store is large.
1,041 live Shopify storefronts that Undercart had fully enriched as of July 2, 2026, with crawls spanning June 25 – July 2, 2026. We excluded domains flagged as likely non-stores and any soft-deleted records. 872 of the 1,041 stores carry a revenue estimate, which is what the revenue-band cuts are computed on.
Undercart fetches each store's live HTML (including Google Tag Manager container scripts) and matches it against a library of ~300 app, pixel, theme, and payment signatures. Each detected app is filed into a category. A store "runs" an app if that signature is active on its storefront.
Revenue is a composite estimate combining catalog size and pricing, review velocity, advertising presence, social reach, and the detected tech stack, confidence-weighted and benchmarked against a truth set of stores with known revenue. Bands are annual: under $100K, $100K–$1M, $1M–$10M, and $10M+.
This is not a random sample of all Shopify stores. Undercart enriches established, discoverable brands, so the set skews large: 83.8% estimate at $10M+/year. Read every figure as describing notable, established Shopify storefronts, not the long tail of new or dormant shops. The sub-$1M bands are small (34 stores), so cross-band comparisons lean on the well-populated $1M–$10M and $10M+ cohorts.
Undercart maintains a live index of Shopify merchants — revenue estimates, full tech stacks, ad signals, social reach, and contact data, re-crawled nightly. The numbers in this report come straight out of that index. If you want this depth on a specific store, a competitor set, or the whole market, that's the product.
