How Much Does CRO Cost? A Transparent Breakdown of Conversion Optimization Pricing

How much does CRO cost? It is one of the harder things to pin down in digital marketing. SEO and paid media have fairly standard pricing. CRO does not. The scope swings widely. A one-time audit of a single landing page is one kind of work. A nonstop, multi-channel testing program is another. Both go by the name "CRO." Yet they share almost nothing in cost or output.

This guide shows what you get at each CRO price point. More important, it shows how to do the math. You can then see if the return is worth the cost at your own traffic and conversion level.

CRO Pricing by Engagement Type

One-Time CRO Audit: $1,500-$8,000

A CRO audit is a diagnostic job. It is a careful review of how your site converts. It looks at your data and how users move through the site. The goal is to find your biggest friction points. At the low end, you get an expert review and a written list of fixes. At the high end, you get more. You get heat maps, session recordings, and funnel data. You also get user research and a ranked roadmap. Each fix comes with an estimated impact. This is the right first step if you need to understand the problem first. Then you can decide on an ongoing program.

Project-Based CRO Engagement: $5,000-$20,000

A project-based CRO engagement has a set scope. It might redesign and test one landing page. It might improve a checkout flow. Or it might run a structured A/B test on the homepage for a set time. This is the most common setup for a clear bottleneck. You know the problem and want a specialist to fix it. Related: cro-agency-vs-diy covers whether a project or an internal program fits better.

Ongoing CRO Program: $3,000-$15,000/month

An ongoing CRO program fits some businesses better than others. It makes sense with heavy traffic and many conversion points. It also helps when your conversion rate trails industry benchmarks by a lot. At $3K-$5K/month, you get a steady testing pace. That is usually 2 to 4 tests a month, plus reporting and rollout. At $8K-$15K/month, you get a full team. That means a data analyst, a UX designer, a copywriter, and a developer. They run test cycles at once across many pages and channels.

How to Calculate Whether CRO Investment Pays

The CRO math is simple. Say your site gets 10,000 visits a month. Say it converts at 1.5%. That gives you 150 leads. Now say each lead is worth $500. Your lead revenue is then $75,000 a month. A 0.5-point lift, to 2.0%, gives you 200 leads. That adds $25,000/month in lead value. Now picture an ongoing program at $5,000/month. Say it drives a steady 0.5-point lift. It pays for itself at about the three-month mark. After that, the extra revenue keeps coming.

The math assumes the lift sticks. It usually does. That is because CRO fixes are built into the site itself. They do not depend on ongoing ad spend. See ux-audit for the diagnostic step that often comes before a CRO program.

"The question is never whether CRO is expensive. The question is whether your current conversion rate is expensive. Most businesses are leaving more money on the table every month than a good CRO program costs all year."

What TTGC Offers in CRO

Through The Glass Creatives treats CRO as a design and data craft. It is not just a tool setup. Each engagement starts with a diagnostic phase. Next comes hypothesis work grounded in real behavioral research. Then the changes go live. These changes are built to convert, not just tested to see what sticks. For a business starting with a site audit, the growth assessment is the first step.
