Conversion Rate Optimization Agency
A conversion rate optimization agency should do more than run A/B tests and email you a monthly report. Build Grow Scale runs your store's entire conversion operation (the testing, the checkout, the data) so every win compounds instead of resetting with the next project.

What a Real CRO Engagement Includes
“One of the things that sets us apart from a lot of other agencies is the way that we test, and how frequently we test.” Most agencies run surface-level changes that make a site look better without putting more revenue in the owner's pocket.
Every BGS engagement starts in the same place: the checkout. “Typically, we want to go to the checkout because if I fix your checkout and now you get a 1% lift there, that's more money in your pocket every day... once your checkout and your cart are optimized, every change we make generates more money for you.”
That sequencing isn't a preference. It's math. “A 1% lift at that spot is a hundred times more valuable than a 1% lift on your homepage.” Once the checkout and cart are solid, testing moves outward to the rest of the store, backed by a clean data layer so every result is trustworthy rather than a coincidence.
Curious what a 1% lift is actually worth on your store? Try our conversion rate calculator before we ever talk.

Built for Shopify Stores
Everything above is delivered by a team that has worked exclusively in Shopify for 10+ years, across 2,500+ brands. That specialization matters because Shopify's checkout, app ecosystem, and theme architecture behave differently from any other platform. A test that works on a generic ecommerce stack doesn't automatically work inside Shopify's constraints.
That is the bar we set for the start of an engagement. Not a strategy deck in month three — money back in the business while the first month is still running.
It also means the CRO work never happens in isolation. The same team that runs your testing program can also touch the theme, the app stack, and the data layer underneath it, because Shopify site builds and re-builds and custom Shopify apps sit inside the same turnkey scope.
The Embedded-Team Model
BGS doesn’t hand a single generalist a login and call it a CRO program. As Matthew Stafford, Managing Partner at Build Grow Scale, puts it: “E-commerce has matured to the level where you can’t be an email expert, and a Facebook Ads expert, and a Google Ads expert, and a CRO expert, and a Google Analytics expert.” What it takes instead is a team of specialists who work well together, the whole point of how the Ongoing CRO Partnership retainer works.
That team structure is also why roles shift as your store’s needs change: in Stafford’s words, “it’s much easier to swap roles and put the right butts in the right seats” than to force one hire to cover every discipline. Testing itself is only reliable with outside eyes on it, too analytics and data consulting that makes tests trustworthy is what keeps the whole program honest, because a team staring at the same site every day stops noticing what a fresh set of eyes catches immediately.

What a typical CRO agency does,
and what BGS does instead
You already know you need conversion rate optimization. Here's what that actually looks like once you're a BGS client.
| Typical CRO Agency | Build Grow Scale | |
|---|---|---|
| What you get | A handful of A/B tests on isolated landing pages | A full growth system across data, testing, builds, and reporting |
| Who runs it | A rotating tester assigned to your account | An embedded team with 10+ years on Shopify, running your store like their own |
| How wins are decided | Generic best-practice guesses | Your store's own data: checkout first, then the pages behind it |
| Reporting | A monthly deck of vanity metrics | Custom reporting built around your P&L, not impressions |
| Commitment | A fixed-scope project that ends | An Ongoing CRO Partnership that compounds |
Who This CRO Engagement Is Built For
Strong Fit
- A Shopify store with real traffic already coming in
- Checkout and cart data you're willing to hand over and trust
- An owner who wants a testing partner, not a one-time page redesign
Probably Not If
- You're pre-product-market-fit and still validating whether people want what you sell
- You're looking for a single A/B test rather than an ongoing testing program
- You're not ready to act on what the data shows
