The first screen
What a buyer sees first on a phone loads first, and anything that can wait does.
For Shopify stores that were told the score is the problem
Speed matters where it costs you sales.
We make Shopify and Shopify Plus stores faster. We start with the pages where slowness costs you buyers, not with the score, because a better number on a test page and more revenue are not the same result.

You have probably seen this already.
The score went up and nothing else did
Someone spent a sprint on speed, the PageSpeed number improved, and sales looked the same the month after.
Every app adds a script
Reviews, upsells, pop-ups, chat, tracking. Each was worth installing, and together they load before the product does.
Mobile is where it hurts
The store feels fine on the office laptop. Most of your buyers are on a phone, on a slower connection, deciding in seconds.
Nobody can say what slow is costing
Everyone agrees the store should be faster. Nobody can say which pages matter, or how much a faster one would earn.
The costly assumption
A faster store is worth paying for. A higher score is not.
Is your store slow where buyers decide, or only on the test?
A PageSpeed score is a lab test of one page on a simulated phone. It is useful, and it is easy to chase. It can rise while the product page your customers actually use stays slow, and it can sit in the middle on a store that sells well, because some themes and apps set a ceiling that no amount of work removes.
So we do not promise a score. Speed optimization improves each store from its own baseline, within what its Shopify theme allows. What we measure is the store your buyers load: the landing pages your ads send people to, the product pages, the cart.
Leak six of nine
What we inspect before anyone touches code.
- Real loading data from your visitors, not only the lab test, split by phone and desktop
- The pages that earn money, ranked by traffic and revenue, measured first
- Apps and third-party scripts: what each one loads, where, and whether it earns its weight
- Images, video and fonts, and whether the theme serves the right size to a phone
- Theme code: what runs before the page can be used
- Anything slowing the cart and the path to checkout
- Whether your analytics can show the effect of a faster page at all
Speed and technical drag is one of the nine places a store leaks revenue, and it is checked alongside the other eight. Sometimes the slow page is not the expensive problem. When it is, it goes to the top of the list.
When speed is the leak
The work, grouped by what it protects.
The product page
Images, reviews and add-to-cart load in the order a buyer needs them, so the page can be used before it is finished.
The app stack
Apps that do the same job are cut down to one, with your approval, and the ones that stay load only where they are used.
The cart
Upsells, shipping estimates and scripts on the way to checkout are trimmed so the last step is the fastest one.
Every change is measured on the same pages it was meant to speed up. If one did not move, we say so.
In order
Measure, rank, fix, measure again.
Baseline
Loading data from real visitors on the pages that earn money, recorded before anything changes.
Rank
What is slow, where, and what it is likely costing, against the other eight leaks.
Fix
The changes that matter most, built and tested away from the live theme, published with your sign-off.
Measure
The same pages, the same measures, after the change.
If you want a read from outside first, the $497 Revenue Leak Audit covers speed and technical drag and is delivered in 3 business days. With access to your analytics, a 21-day Profit Sprint covers all nine leaks.
The evidence
Three leaks, three measured outcomes.
Every result below names the change we made, the sample it was measured across, and the window it was measured over. Where we do not have a published result yet, we say that instead of filling the gap.
Speed is one of the nine leaks, and these are results from the others. A faster store is what lets work like this show up in revenue.

Largest session sample in our test history. Conversion rate was the primary metric. Revenue per visitor rose 3%, which did not clear the decision threshold on its own.

Our longest test window. When the window matters more than the number, this is the one to read.
Projected monthly contribution is extrapolated from the test window. It is not revenue banked, and we will not present it as though it were.
Results are specific to the cited experiments. Not every test wins, and projected contribution depends on the measurement window and store economics.
Six of the nine leaks VASTA inspects do not yet have a published result behind them. Those are described as process, not proof, until a proof pack exists. How we measure
The VASTA agreement
Agency fatigue is earned. These are the boundaries.
- No diagnosis, no pitch.
- No proof, no public claim.
- No scope creep disguised as strategy.
- No-fit means no forced sale.
And no speed project we cannot tie to the pages that earn money.
This works when speed is worth finding.
Likely a fit
- Shopify or Shopify Plus, with meaningful traffic and revenue
- Most of your buyers are on phones
- Your store runs several apps, or a theme that has been customised over the years
- You want speed judged by sales, not by a score
Probably not a fit
- You want a guaranteed score
- Pre-revenue, or too early for the result to be measurable
- You want every app kept, whatever it costs in speed
- You are unwilling to set a baseline before changes go live
Before you talk to us.
No. Speed optimization improves each store from its own baseline, within what its Shopify theme allows. Some themes and apps cap the score whatever is done, so a promised number would be a promise about something we do not control.
Only the ones that cost more in speed than they earn, and only with your approval. Often an app can stay and simply load later or on fewer pages.
Usually not. A rebuild is prescribed only when the theme itself is the constraint, and the reasoning comes with it. See the Development page.
The Audit is delivered in 3 business days. A Profit Sprint runs 21 days and covers speed alongside the other eight leaks. Speed work beyond that is scoped after the diagnosis.
No. Changes are built and tested away from the live theme and published only with your sign-off.
