You’ll often hear about conversion rate optimization (CRO) in the context of eCommerce, but it’s just as critical for digital agencies.
The only real difference is that agencies don’t focus on immediate sales. They need to refine their lead nurturing processes instead to turn prospects into long-term clients.
We caught up with Kurt Philip, founder of Convertica, to talk about conversion rate optimization (CRO) for digital agencies. With years of experience helping businesses fine-tune their websites, Kurt shares practical tips to boost client inquiries and ultimately increase conversions.
Here are some of the key takeaways from our conversation.

What is CRO for digital agencies (and why does it matter)?
CRO for digital agencies is the process of turning website visitors into paying clients, with a well-planned presentation of services. It’s a multifaceted process that involves building relationships, establishing trust, and optimizing lead generation for long-term and high-value services.

The goal of CRO is to ensure that every touchpoint — from the first visit to the inquiry stage — is designed to lead potential clients further into the funnel. Simply put, optimization should make the transition from prospect to client as seamless as possible.
CRO for digital agencies vs eCommerce
Although CRO principles apply to both eCommerce and digital agencies, the approach is different due to the nature of the buying journey.
eCommerce customers make purchasing decisions quickly, so the focus of CRO is on optimizing the user experience to encourage immediate purchases. On the other hand, digital agency clients have a more complex decision-making process:
- Longer sales cycle: Agencies nurture leads over a longer period that often spans a few weeks (or even more).
- Building trust: Online shops rely on immediate trust indicators like user reviews, whereas agencies continuously build credibility through client testimonials, case studies, and strong communication.
- Lead generation optimization: Digital agencies put a lot of effort into optimizing lead capture forms and inquiry processes across multiple touchpoints.
The bottom line is that agencies apply CRO strategies that align with their unique sales funnels and client relationships.
CRO strategies for digital agencies to optimize client conversions

CRO is all about refining how potential clients move through the inquiry process, from the first visit, to the final contract. Here are some proven optimization strategies that digital agencies can use to grow conversions:
1. Simplify your lead generation forms
This is a critical suggestion because lead generation forms serve as the gateway for potential clients to get in touch. Don’t ask for too much information upfront — it will cause potential leads to drop off. A much better option is to prioritize simplicity, like this:
- Keep your forms short: Only ask for relevant information such as name, email, and a brief project description. You can always gather more details later in the process.
- Use clear CTAs: Make sure the call-to-action (CTA) is easy to spot all over the place. As Kurt Philip says:
“It’s super surprising to see some huge websites that have like one very small CTA at the top and that’s it throughout the entire page.”
2. Build trust with client testimonials and case studies
Trust is the cornerstone of agency conversions. Potential clients want to see valid proof that you can deliver results before they commit to working with you, and this is where client testimonials and case studies come in. Some of the best practices in this area include the following:
- Strategic placement: Place testimonials on key pages like the homepage and service pages, and try to focus on quotes that speak to the problems you solve.
- Use case studies: In-depth case studies add to the overall credibility of your agency because they show tangible data and results achieved with your former/current clients.
- Highlight logos or client lists: If you’ve worked with notable clients, it’s always a good idea to display their logos as an instant trust boost for new visitors.
Kurt Philip claims that professional credibility is one of the most important aspects of agency CRO:
“80% of our homepage is basically trust-building stuff: testimonials, case studies, reviews. It’s all about building credibility.”
3. Optimize your inquiry-to-client funnel
Your work truly starts once a potential client submits an inquiry. If you don’t want to lose prospects along the way, it’s important to optimize how you manage leads throughout the inquiry-to-client funnel. This means ensuring you do a few different things:
- Automate follow-ups: Use automation tools to send follow-up reminders and keep your leads engaged.
- Personalization: Tailor your communication to address specific needs or challenges mentioned in the inquiry. This shows that you’ve paid attention and are able to help.
- Consistent engagement: Don’t let leads go cold. Keep the relationship moving forward with regular touchpoints such as emails, calls, demos, or meetings.
Agencies that build an effective funnel can quickly guide prospects through it. In the words of Kurt Philip:
“If there’s an agency with a very clear funnel, you’re going to need much less traffic than the eCommerce website that has 50 products where the traffic is split over the products.”
The importance of split testing for CRO

CRO cannot be productive without split testing (aka A/B testing). Split testing forces you to experiment with different versions of key website elements and determine which ones convert visitors into clients most effectively.
The beauty of split testing is that it removes the guesswork. Instead of assuming which element will perform better, you can rely on data-driven results. Kurt Philip claims that A/B testing helps to make Convertica so successful:
“I keep saying that we have a very high win rate… It’s because we always test everything with our clients because nothing is ever a hundred percent.”
The goal is to continuously refine your website and optimize it for higher conversion rates. For example, agencies should regularly test these elements:
- Headlines and subheadings
- CTAs
- Lead generation forms
- Landing page payouts
Our suggestion is to focus on the pages that matter most. For instance, your homepage and service pages are the key points where conversions happen — testing and optimizing these pages may lead to big improvements.
Another tip is to test one element at a time. For instance, isolate one variable (like the CTA text) to accurately measure its impact. Testing multiple elements at once can muddy the results and make it difficult to determine what’s driving the improvement.
Finally, do not rush your tests. Do your best to gather enough data over a reasonable period to make sure that the results are statistically significant and not influenced by temporary fluctuations.
Final thoughts: CRO is the simplicity game
At its core, digital agency CRO is about making the path from inquiry to conversion as simple as possible. Though optimization strategies vary from one firm to another, the underlying principles remain the same — remove friction, build trust, and guide potential clients through a clear and engaging process.
As Kurt Philip puts it, the idea is to create a straightforward experience for your clients:
“Just make what you want them to do very clear. Make it as easy as possible even for a five-year-old to buy or purchase or sign up.”
