Invesp performed a comprehensive conversion audit, user behavioral research, and data analysis to design and run A/B testing experiments and track weekly results.

Our Research in Detail

Continue reading for a detailed breakdown of our findings, derived from each metric in the report above:

Employees per Agency

  • 89% of conversion rate optimization agencies have fewer than 49 employees, revealing that the CRO market is primarily composed of small businesses.
  • Only 8 out of over 1,200 companies are large CRO agencies with 250+ employees on their teams, suggesting that a large workforce is not a necessary key component for successful operations and that specialized, boutique business models are more commonplace.

Minimum Budget

  • A staggering 62% of conversion optimization agencies offer services within the $1,000 to $10,000 budget range. These numbers demonstrate the ability of CRO solutions to cater to smaller businesses or projects with limited budgets.
  • A small but significant 1% of the market caters to high-end clients with budgets exceeding $50,000, indicating a demand for specialized or enterprise-level CRO services.

Average Hourly Rate

  • Most conversion optimization agencies operate within a mid-market pricing structure with 28% charging between $100/hr and $200/hr and 26% offering services from $51/hr to $100/hr. This majority represents a balance in cost and quality of services provided for businesses looking for value for cost.
  • Approximately 22% of CRO agencies offer budget-friendly hourly rates below $50, catering to clients with smaller budgets or cost-sensitive projects. Specifically, 9% of agencies charge $30/hr or less, while 13% charge $31/hr to $50/hr.
  • Only 3% of agencies operate at the high end of the market, charging premium hourly rates between $201 and $500. These agencies likely provide end-to-end services or cater to high-profile clients with complex needs.

Founding Years

  • The CRO market exhibits diverse company tenures, from established pioneers founded in the early 2000s to innovative startups launched in 2024. This reflects the market’s evolution, combining the experience of established agencies with the agility and fresh perspectives of newer companies.
  • Driven by the expansion of digital marketing and e-commerce, the market saw a steady increase in new agencies established, peaking at 277 new companies from 2015 to 2018. This increase is fueled by advancements in digital technologies and the growing recognition of CRO's importance.
  • 97 new conversion optimization agencies emerged in 2020 as businesses adapted to digital operations. While new agency formation declined slightly in 2021, the overall number remained significantly higher than the years prior, demonstrating the sustained importance of CRO amid and beyond changing market trends.

Industry Focus

  • Marketing and advertising are the primary client sectors for CRO agencies, accounting for 7% of reviews. This strong correlation highlights the critical role of CRO in optimizing brand building and marketing campaigns.
  • The technology and commerce sectors are seconded as primary users of CRO services. Information technology and services (6%) and Computer Software (6%) sectors leverage CRO for product optimization, while financial services (4%) and retail (4%) focus on customer acquisition and retention strategies.

Conversion Rate Optimization Agency FAQs

What is a conversion rate optimization (CRO) agency?

A conversion rate optimization (CRO) agency is a marketing agency that specializes in improving a website's ability to turn visitors into customers or leads. It focuses on increasing conversion rates for its clients.

How does a CRO agency help increase website conversions?

A CRO agency helps increase website conversions by analyzing user behavior and adjusting the site to increase the percentage of visitors who complete a desired action, such as purchasing or signing up for a newsletter.

Which businesses benefit most from CRO services?

CRO services are most valuable for eCommerce stores, SaaS platforms, financial services, and subscription-based businesses, where even the smallest conversion lifts directly increase revenue.

They also benefit B2B companies with high-value leads, such as legal, healthcare, and enterprise tech, where optimizing forms, landing pages, and funnels boosts qualified lead generation and lowers acquisition costs.

What are the top-rated CRO agencies on DesignRush in 2025?

What core and specialized CRO services do they offer?

Conversion rate optimization companies offer services including:

  • CRO audit
  • CRO strategy development
  • A/B testing
  • Landing pages optimization
  • Website audit and optimization
  • Heat mapping
  • Visitor analytics and reporting

Specialized CRO services:

  • Personalization and segmentation
  • Mobile and app CRO
  • Checkout optimization UX/UI enhancements
  • CRO for SEO and paid ads
  • Advanced testing

How much do CRO services cost in 2025?

Depending on the pricing model and the type of project, a CRO agency may charge from $2,000 to $30,000 per month.

How long does it typically take to see improvements in conversion rates?

Most businesses see initial conversion rate improvements within 4-6 weeks once testing and quick wins are implemented. Deeper, more sustained gains usually appear after 3-6 months as multiple A/B tests, UX changes, and optimization cycles compound.

What should you look for in a CRO agency?

Look for a CRO agency with proven case studies, data-driven methodology, and expertise in A/B testing, analytics, and UX/UI design.

Ensure they provide transparent reporting, industry experience, and a clear testing roadmap tailored to your goals. The best agencies also integrate seamlessly with your marketing stack and emphasize measurable ROI.

What warning signs indicate that a CRO agency may not be the right fit?

A CRO agency might not be the best fit if it displays the following warning signs:

  • No proven case studies or vague claims of past success
  • One-size-fits-all approach without tailoring to your business goals
  • Overpromising quick wins without a clear testing roadmap
  • Lack of transparency in reporting or unclear KPIs
  • Little to no UX/UI expertise, focusing only on copy tweaks
  • Ignoring data and relying solely on opinions or assumptions
  • Poor integration skills with your analytics, CMS, or marketing tools

What questions should I ask a conversion optimization firm when choosing one?

Before signing a contract with a CRO agency, ask them the following questions:

  1. How many years of experience do you have in CRO?
  2. Do your team members have relevant certifications like Google Analytics, HubSpot, and others?
  3. How do you make clients stand out from the competition?
  4. What is your approach to A/B testing?
  5. What does your CRO audit process entail, and how long does it last?
  6. How do we define project milestones? What happens if they are not met?
  7. What metrics will you use to define the success of this CRO campaign?
  8. What is the planned budget? Are there any additional costs we can expect?

How does CRO differ from broader digital marketing or UX services?

Conversion rate optimization focuses specifically on turning existing traffic into leads or sales through testing, analytics, and funnel improvements. Digital marketing, on the other hand, drives traffic via channels like SEO, PPC, and social, while UX services improve overall usability and design.

CRO bridges both by using data to maximize conversions from the traffic and experiences those efforts create.

Which testing tools, analytics platforms, and experimentation frameworks do top CRO agencies use?

Top CRO agencies use A/B and multivariate testing tools like Optimizely, VWO, and AB Tasty, together with behavior analytics platforms such as Hotjar, FullStory, Mixpanel, and Heap to track user actions. They also rely on feedback tools for surveys and usability testing, plus onboarding optimization tools like Userpilot to refine customer journeys.

For experimentation, conversion rate optimization agencies rely on frameworks such as ICE, PIE, and PXL to prioritize tests, along with models like the Lift Framework and JTBD for structured hypothesis building.

How legitimate is the content in the FAQs?

Our goal is to provide accurate and useful information to both businesses and agencies, which is why we partnered with Mike Melen, co-founder of digital marketing agency SmartSites. He shared best practices for optimizing user journeys and reducing friction in the conversion process. 

As a young entrepreneur, Mike Melen sold his first company at 19 years old. He has since led SmartSites, which has garnered eight Inc. 5000 recognitions and more than 1,000 5-star reviews. Melen’s work in the marketing field has also received honorable mentions from Forbes, AdWeek, and Inc. Magazine.
