Essential questions you need to consider before
choosing a CRO agency.
A conversion rate optimization agency, also called a conversion optimization agency or CRO agency, provides a unique, cross-functional blend of analytics, research, creative, and development talent to drive measurable increases in conversions and revenue for client websites.
A CRO agency like ours specializes in squeezing every last drop of performance out of your website.
We’re here to make sure as many of your visitors as possible actually do what you want them to do — whether that’s making a purchase, signing up for your newsletter, starting a trial, calling you, or filling out your contact form.
So, what is a conversion rate optimization agency?
It’s your partner in maximizing the efficiency of your website.
We dive into the science of conversion and the art of user experience to turn more of your visitors into loyal customers.
The result? Sustained growth and increased revenue, driven by a site that’s firing on all cylinders.
A conversion rate optimization agency is like your personal team of data-driven detectives, dedicated to turning more of your website visitors into customers, subscribers, or leads. But we’re not just talking about tweaking a few buttons and calling it a day.
Here’s how a conversion rate optimization agency like Conversion Sciences gets the job done:
1. Diving Deep into Data
Visitor Behavior Analysis: First, we get to know your visitors. We use tools like Google Analytics, heat maps, and session recordings to figure out where they’re getting stuck, confused, or just plain lost on your site. Think of it as a digital autopsy that uncovers why many of your potential conversions died.
User Research: But we don’t stop there. We conduct surveys and user interviews, build personas, and map out the customer journey to fully understand what your audience needs from you.
2. Crafting Hypotheses (or Educated Guesses)
Identifying Issues: Once we’ve dissected the data, it’s time to zero in on what’s tripping up your visitors. Maybe your landing page is a maze, you’re burying the most important element of your value proposition, or your offer and CTA are failing to connect with visitor needs. Whatever it is, we’ll find it.
Hypothesis Creation: Then, we play detective. We create hypotheses like, “If we change this button color, will they click more?” or “What if we simplify the checkout process — will fewer people bail?” We’re not just guessing here; we’re making educated bets based on data and prioritizing our efforts accordingly.
3. Running the Experiments
A/B Testing: Now for the fun part — testing! We’ll set up A/B tests where we pit two versions of your webpage against each other to see which one wins.
Multivariate Testing: Got more complex problems? We’ll throw in multivariate testing to juggle multiple changes at once, figuring out which combination works best. It’s CRO on expert mode.
4. Making Data-Driven Changes
Implementing Winning Variations: After the tests are done and the data’s crunched, we roll out the winning changes across your site. No more guessing — just proven tweaks that drive results.
Iterative Optimization: We keep the optimization wheels turning with continuous monitoring and new tests to make sure your site stays ahead of the curve.
5. Breaking It Down in Reports
Transparent Results: We’re big on transparency, so expect detailed reports that don’t just give you the numbers but also explain what they mean. How much did your conversion rate improve? What’s your ROI? We’ll tell you.
Actionable Insights: Plus, we’ll give you insights that go beyond the numbers, helping you make smarter decisions across your business.
6. Beyond the Website: Cross-Channel Optimization
Multi-Channel Strategy: Conversion rate optimization isn’t just about your website. We optimize your entire user journey across email, social media, and ads, ensuring a seamless experience wherever your audience interacts with your brand.
7. Holistic Growth
Full-Funnel Optimization: From the first touchpoint to post-purchase engagement, our CRO agency optimizes every stage of the customer journey to maximize lifetime value and drive sustainable growth.
The cost of hiring a conversion rate optimization agency isn’t one-size-fits-all — it’s more like building a custom house. Your cost depends on what you want and how much you can or should reasonably spend. For most businesses where it makes sense to engage a CRO agency, the costs for ongoing CRO management typically range from $5,000 to $16,000 per month for comprehensive, expert program management.
But if your business has an exceptionally large sample size with the ability to explore multiple optimization lanes at once, you could be looking at a range between $20,000 to $30,000 per month. It’s important to remember, you’re not just paying for tweaks and quick fixes — you’re investing in detailed analytics, custom testing frameworks, and in-depth user research that can turn your website into a conversion powerhouse.
For one-off projects like audits, analytics implementations or landing page designs, CRO agency costs range from $5,000 to $25,000+, depending on the scope and complexity.
Accelerate revenue growth by 12 to 18 months.
Improve conversion quality: Bigger shopping carts, returning customers, better quality leads, lower cart abandonment rates.
Raise the value of every visitor. You vested time and money on your social media channels, paid ad campaigns and organic efforts. A CRO agency can help you convert more of these prospects/opportunities.
Increase profit margins by lowering cost per acquisition.
Identify issues with your positioning, messaging, and conversions more quickly. A CRO will be watching your data, so conversion-related issues won’t fall through the cracks.
Identify low hanging fruit (where you will get the most bang for your buck). The data used for conversion optimization will uncover additional opportunities that drive more revenue.
Every conversion rate optimization agency has its own unique focus. Ultimately, the best CRO agency is the one that’s right for your company. That said, here’s how to find your best fit:
Set realistic expectations. CRO is a process of testing and experimentation, and most tests are inconclusive. Are you comfortable with these odds?
Ask them how they work with websites with your “sample size.” Sample size is the volume of conversions across your website, channels, devices, and pages. It determines the most appropriate CRO strategy and CRO tactics for your website.
Be aware that if your website doesn’t have a big enough sample size, AB testing won’t work. It will give you false positives and false negatives while wasting your valuable time and money.
A CRO agency should not talk about AB testing until you have 500 conversions per month. However, they can use their experience and analytical powers to help you prioritize the changes you should be making to your online business. An ethical CRO agency will talk with you honestly about the strategies that can work for you.
Do you get an honest, high-integrity vibe from them? You should expect them to be brutally honest with you about where you are as a business and what tool or tools in the CRO toolbox are most appropriate for your business. Ask how they communicate with you and how often.
When you’re looking to hire a CRO agency, the guarantee they offer can say a lot about their confidence and commitment to delivering real results. Here’s what you should look for:
The best conversion rate optimization agencies, like Conversion Sciences, don’t just talk the talk — they walk the walk with performance-based guarantees. This means they’re willing to put their money where their mouth is by promising a certain level of improvement in your conversion rates. For example, they might guarantee something like a 15% or higher lift in conversions. Why does this matter? Because it aligns your success with ours.
A reputable CRO agency will guarantee transparency in its processes and provide measurable results. This isn’t just about handing you a fancy report with a bunch of numbers — it’s about showing you exactly how their work is moving the needle on your conversion rates. At Conversion Sciences, we’re all about tracking results with statistical accuracy so you get clear, data-backed evidence of success.
Conversion rate optimization isn’t a “set it and forget it” kind of deal. The best conversion rate optimization agencies understand this and offer long-term support as part of their core value. This means ongoing testing, continuous monitoring, and iterative improvements to ensure your conversion gains aren’t just a one-time spike but a sustained upward trend.
Here are some key signals that indicate working with a conversion rate optimization agency might be a good move for you.
Conversion optimization thrives on testing, and testing thrives on sample size. Since conversion optimization increases your marginal rate of return and decreases your marginal cost, it is a force multiplier. The more conversions (or force) you have, the greater the impact of the multiplier.
Your website is pulling in lots of visitors, but those visitors aren’t converting at a rate that is allowing you to reach your goals.
For businesses that live and die by online sales or lead generation — think e-commerce sites and B2B companies — conversion optimization is a no-brainer. You simply can’t afford to run blind or fall out of sync with your customer’s needs.
Conversion optimization isn’t a quick fix. It’s an ongoing process of testing, learning, and tweaking. If you’re committed to making your site better every day and are ready to invest in continuous improvement, conversion optimization is going to be the hub of your wheel. We often say our job is to put continuous upward pressure on your conversion rate at a rate that counteracts and defeats the constant downward pressure on your conversion rate.
In a cutthroat industry, every tiny improvement counts. Conversion rate optimization can give you that competitive edge by ensuring your site is a lean, mean, converting machine. It’s about turning every click into a customer, which in a competitive market or lean margin industry, can make all the difference.
Already spending on PPC, SEO, or social media ads? Conversion optimization is like supercharging your efforts. By boosting the percentage of visitors who convert, CRO makes sure you’re squeezing every drop of value from your marketing budget and increases profit margin by reducing CAC.
A reputable CRO agency will ask questions to get a feel for these signals. If CRO isn’t right for you at this time, they’ll let you know.
It might seem like a no-brainer to have your existing PPC or SEO agency take on conversion rate optimization (CRO) since they’re already managing a big chunk of your digital marketing. But before you hand them the keys to your conversions, here’s why you might want to consider a specialized conversion rate optimization agency instead:
Sure, PPC and SEO agencies are wizards at driving traffic, but once that traffic lands on your site, the game changes. CRO isn’t just about bringing people in the door — it’s about getting them to take action once they’re there. A specialized conversion rate optimization agency has a deeper understanding of user behavior, advanced testing techniques like A/B and multivariate testing, and the psychology behind what makes visitors click, sign up, or buy. Conversion optimization is a nuanced discipline that requires expertise in areas like data analysis and user experience design — skills that a dedicated conversion rate optimization agency excels at.
Your PPC/SEO agency is laser-focused on getting more people to your site. That’s great, but conversion optimization is all about what happens next. A conversion rate optimization agency is single-minded in its mission to turn visitors into customers or leads. They’re not juggling traffic generation with CRO; they’re 100% focused on improving the percentage of visitors who take the action you want them to take. This kind of specialized attention can make a big difference in your bottom line.
Conversion optimization is a playground for data geeks and experimenters. It involves sophisticated tools and testing methods that go beyond what’s typically used in PPC or SEO campaigns. A conversion rate optimization agency has access to cutting-edge testing platforms, heatmaps, session recordings, and advanced analytics tools that provide deep insights into user behavior. These tools allow them to run precise, effective experiments that can lead to significant gains in your conversion rates.
Your PPC/SEO agency knows your site inside and out — but that might actually be a disadvantage when it comes to CRO. They might be too close to your current strategy to see opportunities for improvement. A specialized conversion rate optimization agency brings a fresh, unbiased perspective. They’ll look at your site with new eyes, which can be crucial for uncovering issues or opportunities that have been overlooked.
Conversion optimization isn’t something you just tack onto an existing strategy — it’s a discipline with its own set of rules, processes, and best practices. A conversion rate optimization agency follows a structured approach that includes continuous testing, data analysis, and iterative refinement. While your PPC/SEO agency might offer CRO as an extra service, it’s not their main gig. A dedicated conversion rate optimization agency, on the other hand, lives and breathes conversion optimization.
When your sole focus is on improving conversion rates, you’re more likely to get a higher return on your CRO investment. A conversion rate optimization agency’s specialized knowledge, tools, and experience often lead to more effective optimizations, which can significantly improve your ROI.
When you partner with Conversion Sciences, your team will need to supply a few key resources to ensure the collaboration runs smoothly and has a successful outcome.
Here’s what you’ll need to bring to the table to partner effectively with our CRO agency:
Your team will need to provide access to your website’s analytics tools, such as Google Analytics, Adobe Analytics, or any other platforms you use to track user behavior and site performance, identify opportunities for improvement, and measure the impact of conversion optimization efforts.
We will ask your development team to implement an experimentation tool for us to use. Or, if you already have one, we will use that.
To tailor the CRO strategies to your specific business goals, your team’s input is crucial. Key stakeholders, such as marketing managers, product owners, and customer experience leaders, should be available to provide insights, approve strategies, and give feedback throughout the process. Regular meetings and updates ensure everyone is aligned and the strategies are meeting your business objectives.
Clear and open communication is key to a successful CRO project. Your team should be prepared to engage in regular communication with the Conversion Sciences team, whether through email, project management tools, or scheduled meetings. This ensures that all parties are informed, any issues are promptly addressed, and the project stays on track.
By providing these resources, your team will help ensure that the collaboration with Conversion Sciences is effective and that the conversion optimization strategies implemented lead to measurable improvements in your website’s performance.
When you choose us as your CRO agency, the timeline for seeing results can vary based on a few factors — your goals, your sample size, what kind of work we are doing, and the types of tests we’re running. Here’s a general idea of what the process looks like and how long each phase might take:
We kick things off by getting everything set up. This means diving into your analytics data, conducting a thorough website audit, and pinpointing key areas for improvement. During this time, we’ll also have deep-dive sessions with your team to get a solid grasp of your business goals, target audience, and the conversion challenges you’re facing.
Once we’ve got a handle on the current state of your site, we move into the hypothesis phase. Here’s where we start brainstorming changes that could boost your conversion rates. These ideas are then translated into A/B tests, multivariate tests, or other experiments. We’ll design different versions of your website pages, set up tracking, and get everything ready to launch the tests. This phase is all about planning — laying the groundwork for tests that will give us actionable insights.
Now, it’s showtime. We launch the experiments and start collecting data. Depending on your site’s traffic and the nature of the tests, it could take a few weeks to gather enough data to see what’s working and what’s not. Typically, a single test runs anywhere from 2 to 8 weeks. The key here is reaching statistical significance, which ensures that the results we’re seeing are reliable and not just a fluke.
Once the tests wrap up, we dive into the results to see which variations performed best. This analysis phase is followed by implementing the winning changes across your site. If we’ve got a clear winner, you could start seeing improvements pretty quickly after implementation. This phase is about turning data into action, making sure the successful strategies are live and ready to drive conversions.
Here’s the thing about conversion optimization — it’s not a one-and-done deal. While you might see some positive changes within the first few months, the biggest gains often come from ongoing optimization. We’ll keep running new tests, analyzing fresh data, and tweaking your site to drive continual improvements. Conversion rate optimization is a marathon, not a sprint, and we’re with you every step of the way.
When you bring Conversion Sciences on board as your conversion rate optimization agency, you’re not just hiring one person — you’re getting a lab full of scientists and technicians, each playing a crucial role in supercharging your website’s performance. Here’s a peek at the key players who will be working on your project:
Your project’s mastermind is a dedicated Conversion Scientist®. This role is unique to Conversion Sciences and is the heart of our approach. The Conversion Scientist manages everything from developing hypotheses to executing tests and analyzing results. They combine data analysis, user research, and strategic insight to ensure every conversion optimization effort is rooted in scientific rigor and tailored specifically to your business needs. Think of them as your CRO quarterback, calling the plays and ensuring everything runs smoothly.
Data Analysts are the detectives of your project, digging into performance metrics and user behavior data. They spot patterns, trends, and opportunities for improvement that might not be immediately obvious. These insights are the foundation for developing effective optimization strategies and for measuring the impact of any changes. With data analysts on the case, every decision is data-driven, cutting down on guesswork and boosting the chances of success.
The design team, known as Creative Scientists, is all about making your website not just look good but perform even better. They design A/B test variations, optimize landing pages, and ensure every visual element of your site is aligned with the CRO strategy. Their work is where creativity meets science — making sure design changes don’t just catch the eye but also drive conversions.
The Developers at Conversion Sciences are the tech wizards who bring the CRO strategy to life on your website. They handle the technical side of things — coding A/B tests, tweaking the backend, and making sure all the changes run smoothly without a hitch. They’re the ones who make sure the beautiful designs and smart strategies actually work in the real world.
When you’re shopping around for a conversion rate optimization agency, you’ll quickly find that not all are created equal.
