Conversion Engineering for Ecommerce and Paid-Traffic Sites

We rebuild your measurement layer, read the real user journey, and engineer the fixes in your codebase. If you are buying traffic against a funnel nobody has instrumented properly, the cheapest growth available to you is already on your site.

The short answer

Conversion rate optimization (CRO) is the practice of increasing the percentage of visitors who complete a valuable action — a purchase, a form, a booking, a call. Done properly it is a measurement discipline before it is a design discipline: you instrument the funnel accurately, identify where qualified users drop out and why, fix the specific cause, and verify the change against clean data. The most common reason CRO programs underperform is that the underlying analytics were wrong from the start, so every decision downstream was made on bad numbers. Engagements at Smith Network Solutions begin at $3,000 per month and are delivered remotely nationwide.

Most CRO agencies test. We instrument, then engineer.

A typical conversion agency starts by A/B testing things it can change without a developer — headlines, button colors, hero images. That work has a ceiling, and it is low. We start somewhere else: we rebuild your measurement layer until the data is actually trustworthy, then read the user journey end to end and find where revenue is leaking. Usually it is not the headline. It is a checkout step that fails silently on mobile Safari, a shipping estimate that appears after the payment form, a third-party script blocking interaction for four seconds, or a purchase event that has been double-firing for a year and quietly ruining every optimization decision your ad platform makes. Those are engineering problems. We are engineers, so we fix them in your codebase rather than filing a ticket and waiting.

The cheapest growth you can buy is already on your site

Acquiring a new customer gets more expensive every year. Converting a visitor you already paid for does not. If your site converts at two percent, ninety-eight out of every hundred visitors you bought left without buying — and a meaningful share of them left for a reason you could fix this quarter.

The reason that opportunity sits untouched at most companies is not indifference. It is that finding the reason requires trustworthy data, and producing trustworthy data requires engineering. Marketing teams are handed a dashboard and asked to explain a number that nobody has verified. So the conversation stays at the level of headlines and hero images, because that is what the available evidence can support.

We start by making the evidence good. Then the answers stop being opinions.

How an engagement runs

  1. 1

    Validate

    We test whether your analytics are telling the truth — reconciling reported revenue and conversions against your order system or CRM, checking for duplicates, broken triggers, cross-domain attribution loss, and consent misconfiguration. Nothing downstream is worth doing until this passes.

  2. 2

    Diagnose

    With clean data we build the real funnel and segment it by device, browser, source, and landing page. Aggregate conversion rate hides almost everything worth finding; the actionable failure is nearly always confined to a segment.

  3. 3

    Explain

    For each significant drop-off we identify the mechanism — session replay on the failing segment, reproduction on real devices, network waterfall analysis, and a read of the components involved. The output is a cause, not a hypothesis.

  4. 4

    Ship

    We implement the fix in your codebase. This is the step that separates this from an audit, and it is the reason the work compounds instead of accumulating in a document nobody has capacity to act on.

  5. 5

    Measure

    Every change is verified against the metric agreed at the start — usually revenue per session or qualified leads per unit of spend, not raw conversion rate, since raw rate can be improved by making your traffic worse.

Developers

not a marketing agency with a dev contractor

The people who audit your funnel are the same people who ship the fix. We build production software — custom applications, ecommerce platforms, and internal systems — which is why we find the failures that show up in code rather than in a heatmap.

Full stack

measurement, front end, back end, and infrastructure

We are not limited to what a tag manager can reach. We instrument server-side, fix render-blocking third-party scripts, refactor checkout components, and change hosting configuration when that is what the data points to.

Retained

ongoing engagements, not one-off audits

Conversion work compounds. Our clients stay on a monthly engagement because every cycle produces a new instrumented hypothesis, a shipped change, and a measured result — and because the measurement layer needs an owner as the site keeps changing.

Frequently asked questions

What is conversion rate optimization?
Conversion rate optimization is the practice of increasing the percentage of visitors who complete a valuable action — a purchase, a form submission, a booking, or a phone call. Done properly it is a measurement discipline before a design discipline: instrument the funnel accurately, find where qualified users drop out and why, fix the specific cause, then verify the change against clean data.
How is your approach different from a typical CRO agency?
Most conversion agencies are limited to changes they can make without a developer, so the work concentrates on headlines, imagery, and layout tests. We are a software development firm. We rebuild the measurement layer, read the front-end and back-end code, and ship fixes into your repository — which is where the larger problems usually live.
How much does conversion rate optimization cost?
Our engagements begin at $3,000 per month and include implementation, not just recommendations. The initial conversion audit is free for qualified businesses. Market rates for retained CRO run from roughly $2,000 to $20,000 per month, and the largest driver of the range is whether the firm can actually build the fixes.
Do you only work with businesses in Atlanta?
No. Conversion engineering is delivered remotely and we work with clients nationwide. We are headquartered in the Atlanta metro, so clients in Georgia also get on-site working sessions when that is useful.
How long before we see results?
The first measurable changes usually land in weeks four to eight. The first month is weighted toward diagnosis and rebuilding the measurement layer, because shipping changes before the data is trustworthy means you cannot tell whether they worked.
What if our analytics are a mess?
That is the normal starting condition and it is the first thing we fix. In the large majority of sites we audit we find at least one tracking defect serious enough to have distorted every optimization decision made in the prior year.
