Why the Smartest WordPress Agencies Offer CRO
The Admin Bar's 2025 survey of hundreds of WordPress professionals turned up something worth paying attention to. Agencies that offer conversion rate optimization services are outperforming those that do not, by a meaningful margin across nearly every metric.
If you are building WordPress sites but not offering CRO, here is what the data shows.
1. CRO agencies pay themselves more with similar team sizes
Agencies offering CRO services were twice as likely to pay themselves over $100,000 per year compared to agencies that do not. Their average team size was only slightly larger, 3.0 people versus 2.7.
The work is more strategic and the billing reflects that. You are not competing on hourly rate for design work. You are being paid for outcomes.
2. Recurring revenue is significantly higher
CRO agencies were far more likely to report recurring monthly revenue above $5,000. Over 30 agencies in the survey reported recurring revenue of $20,000 or more per month.
The reason is straightforward. CRO is ongoing work. You run a test, implement the winner, find the next thing to improve, and repeat. That is a retainer, not a project. Clients stay because the results keep coming.
This is the main way agencies get off the project-to-project cycle. If you finish a website and hand it over, the relationship ends. If you are actively improving conversions on that website every month, the relationship continues.
3. Hourly rates are higher
The average hourly rate for CRO agencies in the survey was $112, compared to $93 for agencies without CRO services.
When you are improving a client's conversion rate you are directly affecting their revenue. That changes the conversation from "how much does this cost" to "what is the return." It is a different kind of engagement and it gets priced differently.
4. AI adoption is significantly higher
72 percent of CRO agencies reported fully embracing AI in their workflow. Only a small fraction of non-CRO agencies said the same.
That gap makes sense. CRO already requires analyzing data, forming hypotheses, and iterating quickly. AI tools fit naturally into that workflow. Agencies doing CRO are already used to working with data and testing ideas, which makes AI adoption a smaller leap.
5. They work across multiple builders
CRO agencies in the survey were not locked into a single page builder. They worked across Bricks, Elementor, Breakdance, Kadence, and others, choosing tools based on what works for the project rather than defaulting to one stack.
That flexibility matters for CRO because testing often requires working inside the builder to create variations. A tool like AB Split Test integrates natively with all the major builders so you can test elements without switching workflows.
What this looks like in practice
Adding CRO to your agency does not mean overhauling your services overnight. Most agencies start by running split tests on one or two client sites, building a process, and expanding from there.
AB Split Test has an Agency Hub that lets you manage tests across multiple client sites from a single dashboard. You can see every running test, check results, and jump into heatmaps for any client without logging into each site individually.
The white label option lets you present the interface under your own branding, and public shareable reports give you a clean way to show clients their results without giving them a WordPress login.
The practical case
CRO is not the only way to grow an agency but the survey data is clear. Agencies that measure and improve client results earn more, retain clients longer, charge higher rates, and are better positioned as AI changes what clients expect from their web professionals.
Building beautiful sites will always matter. Proving that those sites actually work is what creates long-term client relationships.
