Conversion rate optimization pricing is one of the more variable categories in digital marketing services. Unlike SEO or paid media, where pricing structures are relatively standardized, CRO engagements vary enormously in scope: a one-time audit of a single landing page and a multi-channel, multi-variant continuous optimization program are both called "CRO" but have almost nothing in common in terms of investment or output.

This guide maps what you actually get at each CRO price point - and, more importantly, how to calculate whether the return justifies the investment at your current traffic and conversion level.

CRO Pricing by Engagement Type

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

A CRO audit is a diagnostic engagement: a structured review of your site's conversion performance, behavioral data, and user flow to identify the highest-priority friction points. At the lower end of this range, you get a heuristic expert review and a written recommendations document. At the higher end, you get behavioral data analysis (heat maps, session recordings, funnel analytics), user research synthesis, and a prioritized implementation roadmap with estimated impact per recommendation. This is the right entry point for businesses that need to understand the problem before committing to an ongoing program.

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

A project-based CRO engagement covers a defined scope: redesigning and testing a specific landing page, optimizing a checkout flow, or running a structured A/B testing program on the homepage for a defined period. This is the most common engagement structure for businesses that have identified a specific bottleneck and want a specialist to solve it. Related: cro-agency-vs-diy covers whether a project engagement or internal program is the right fit.

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

Continuous CRO programs make sense for businesses with significant traffic, multiple conversion touchpoints, and a meaningful difference between their current conversion rate and industry benchmarks. At $3K-$5K/month, you get a structured testing cadence (typically 2-4 tests per month), reporting, and iterative implementation. At $8K-$15K/month, you get a full optimization team: data analyst, UX designer, copywriter, and developer - all running optimization cycles simultaneously across multiple pages and channels.

How to Calculate Whether CRO Investment Pays

The CRO ROI calculation is straightforward: if your site receives 10,000 visits per month and converts at 1.5%, you generate 150 leads. If the average lead value is $500, your monthly lead revenue is $75,000. A 0.5-point lift in conversion rate (to 2.0%) produces 200 leads - an additional $25,000/month in lead value. An ongoing CRO program at $5,000/month that produces a sustainable 0.5-point lift pays for itself at roughly the three-month mark and generates pure additional revenue indefinitely after that.

The calculation assumes the lift is sustained - which it usually is, because CRO improvements are baked into the site's structure, not dependent on ongoing ad spend. See ux-audit for the diagnostic starting point that often precedes 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 annually." - Ravve Jay, TTGC

What TTGC Offers in CRO

Through The Glass Creatives approaches CRO as a design and data discipline - not a tool-configuration service. Our CRO engagements begin with a diagnostic phase, move through hypothesis development grounded in behavioral research, and implement changes that are designed to convert, not just tested to see what happens. For businesses starting with a site audit, the growth assessment is the first step.
