Conversion Rate Optimization
Conversion Rate Optimization, Engineered to Ship the Fix
Most CRO agencies hand you a report and a backlog. We test, then ship the winning variant into production one accountable team running the experiment and writing the code. More revenue from the traffic you already have.

Test → Build → Ship
One team runs the experiment and deploys the winner. No hand-off, no dev-queue wait.
Data, not opinions
GA4, session replay, and behavioral analysis decide what to test not a redesign hunch.
Speed is conversion
We fix the Core Web Vitals and checkout latency that marketing-only CRO shops can’t touch.
AI-assisted prioritization
Our AI unit helps rank hypotheses by projected impact so you test the highest-impact bets first.
The problem with most CRO
Traffic isn’t your problem. What happens after the click is.
You’re paying to acquire visitors, and the majority leave without converting. Industry conversion rates average roughly 2–5% across sectors, and lower on many eCommerce stores meaning most of your marketing spend never turns into revenue. The gap is rarely the traffic. It’s friction, unclear value, slow pages, and untested assumptions.
The catch: most CRO partners diagnose that friction, then hand you a slide deck. Fixing it becomes your engineering team’s problem and it sits in a backlog for weeks while the leak keeps costing you.
❌
Recommendations you can’t ship. A prioritized test list is worthless until someone builds it.
❌
Redesigns based on taste. Big-bang rebuilds with no experiment to prove they helped.
❌
Analytics you can’t trust. Broken GA4 events mean you’re optimizing against bad data.
❌
Speed ignored. A three-second load kills conversions no amount of copy testing recovers
❌
No accountability for outcomes. The agency tests; your team owns whether revenue actually moves.
The CRO Program
A conversion program that ends in shipped code
Every service below feeds one loop: find the friction, prove the fix with an experiment, then deploy it. Research and engineering under one roof.
Conversion Research & Funnel Audit
Quantitative and qualitative diagnosis of where visitors drop off, backed by analytics, heuristics, and behavioral data not guesswork.
A/B & Multivariate Testing
Statistically sound experiments with clear hypotheses, proper sample sizing, and honest read-outs on what won, what lost, and why.
Landing Page & Product Page Optimization
Message clarity, layout, social proof, and calls-to-action tested and rebuilt on your highest-traffic, highest-intent pages.
Checkout & Cart Abandonment Optimization
Friction removal across the checkout flow guest checkout, field reduction, trust signals, and recovery flows that reclaim lost carts.
UX & Behavioral Analysis
Heatmaps, scroll maps, and session replay reveal where real users hesitate, misclick, and give up the “why” behind the numbers.
Core Web Vitals & Speed Optimization
LCP, INP, and CLS engineering. Faster pages convert better and this is friction only an engineering partner can actually remove.
GA4 & Analytics Instrumentation
Clean event tracking, funnels, and goal setup so every decision rests on data you can trust. Google Partner-grade GA4 implementation.
Personalization & Segmentation
Tailored experiences by source, device, and intent so anonymous and returning visitors each see the version most likely to convert.
Form & Lead-Capture Optimization
Field-level analysis, smart defaults, real-time validation, and multi-step flows that lift completion without losing lead quality.
Ongoing Experimentation Program
A continuous test-build-ship cadence with a shared roadmap, so wins compound month over month instead of stalling after one audit.
Why AddWeb
Most agencies sell you a service. We sell you an outcome.
Three things separate an engineering-led CRO partner from a pure-play testing shop.
The wedge
We ship the fix, not a PDF
Pure-play CRO agencies test and hand you a backlog then you wait on a dev team to build it. At AddWeb, the same team that designs the experiment writes and deploys the production code. The loop from insight to live change closes in days, not quarters.
Instrumented
Data-driven, GA4-native
As a Google Partner with GA4 and Adobe analytics depth, we start by making sure your measurement is trustworthy. Then our dedicated AI unit helps prioritize hypotheses by projected impact so test budget goes to the bets most likely to move revenue.

Answers
Conversion Rate Optimization FAQs
Conversion rate optimization is the practice of increasing the percentage of your visitors who take a desired action a purchase, signup, form submission, or demo request by systematically removing friction and testing improvements. It combines behavioral data analysis, A/B testing, and UX and performance engineering to turn more of your existing traffic into revenue, without needing to buy more traffic.
Most CRO agencies run experiments and hand you a prioritized backlog then your engineering team has to build the winning changes, which often stalls for weeks. AddWeb is an engineering-led partner, so the same team that designs the experiment also writes and deploys the production code. Insight becomes a live change in days, not quarters, and one team stays accountable for the outcome.
It includes conversion research and funnel auditing, GA4 and analytics instrumentation, A/B and multivariate testing, UX and behavioral analysis, landing and product page optimization, checkout and cart-recovery work, Core Web Vitals and speed engineering, and an ongoing test-build-ship cadence. The difference is that the build and deploy steps are handled by the same team, not thrown over a wall.
Meaningful results typically emerge over the first few months as tests reach statistical significance and winning changes ship. Timelines depend on your traffic volume, the current state of your funnel, and how much technical friction exists. Higher-traffic sites reach conclusive results faster; lower-traffic sites often benefit first from research-led UX and speed fixes while tests gather data.
We run controlled experiments. A redesign with no test behind it is a guess, and big-bang rebuilds can quietly lose revenue. We form a hypothesis, size the sample correctly, run the A/B or multivariate test, and read the result honestly keeping only the variants that actually beat the control.
We start from data, not opinion. Analytics show where visitors drop off, behavioral tools like heatmaps and session replay show why, and we rank hypotheses by projected impact and effort with our AI unit helping prioritize. Test budget goes to the highest-impact bets first, usually on high-traffic, high-intent pages like checkout, pricing, and key landing pages.
Yes that is the entire point of CRO. By converting more of the visitors you already have, you generate more revenue and leads from the same traffic and marketing spend, which also lowers your effective cost per acquisition. Even modest, compounding lifts translate into significant revenue over a year.
Yes, substantially. Slow pages and laggy checkouts increase bounce and abandonment in ways that copy and layout testing cannot recover. Because we are an engineering partner, we optimize Core Web Vitals LCP, INP, and CLS and reduce checkout latency directly. This is friction that marketing-only CRO shops usually cannot fix.
We work across the modern CRO stack: Google Analytics 4 for measurement and funnels as a Google Partner, mainstream A/B testing and behavioral platforms for experiments and session replay, and Datadog for performance monitoring. The specific tools are chosen to fit your platform and goals, and we make sure your instrumentation is trustworthy before we optimize against it.
Yes. We run CRO across Shopify, WooCommerce, Adobe Commerce, headless commerce, and fully custom stacks. As an official WooCommerce and Shopify partner with deep custom-engineering experience, we can implement winning changes natively on your platform rather than bolting on scripts that slow the site down.
CRO engagements are scoped to your funnel, traffic, and goals rather than sold as fixed packages, so pricing is defined during Discovery once we understand your baseline and the work involved. We compete on outcomes and engineering depth, not on undercutting on price, and every estimate is line-itemed with no padded contingencies.
You do. All work product, source code, experiment data, and instrumentation transfer to you under a US-law-governed agreement, and we sign a mutual NDA before any scoping conversation. There is no lock-in the winning variants live in your codebase.
Yes, and it is common. We frequently plug into an existing marketing or product team running the research and engineering while your team owns strategy and brand or run the full program end to end. Sprint reviews, shared roadmaps, and direct access to engineers keep everyone aligned.
