Let’s get started.

A CRO audit is an in-depth assessment of your website or landing page’s performance to help you determine how effective your landing page/website is in terms of driving conversions or the desired action (completing a form, scheduling a demo, downloading a resource) from visitors.

• UX

• Content

Primary goals of a CRO audit

The primary goals of conducting a CRO audit are to:

Conducting a comprehensive CRO audit is essential for identifying and addressing conversion bottlenecks, understanding user behavior, and ultimately boosting ROI by optimizing the landing page and conversions.

Failing to conduct these audits can lead to common CRO mistakes, such as overlooking critical user journey insights or missing out on potential improvements that could significantly enhance your site's performance.:

1. Identify potential gaps or pitfalls

Imagine you’ve followed all the required instructions to create a conversion-friendly landing page. Unfortunately, conversions have dropped even lower than they were before. How would you identify the issue?

Guess what will help you? A conversion optimization audit. By conducting a comprehensive conversion rate audit, you will be able to pinpoint the potential issues, enabling you to optimize and boost the conversions.

2. Understand more about your users’ journey

A CRO audit helps you analyze and understand how the users behave or interact with the elements on your website.

Why is that important?

When you perform a CRO audit, you can see whether the visitor is taking the desired action or where they’re dropping off. This information helps you identify where the issues are.

For instance, if the users are dropping off at the checkout page, it can mean a few things:

In short, by understanding the user’s journey you have something actionable. Now, you can make the optimizations, streamline your customers’ journey, and eventually drive conversions.

3. Boost ROI

CRO audits are meant to identify and fix issues that negatively impact conversions. When you fix these issues, your conversions grow - meaning you get more value from your existing traffic. And all this translates to more ROI on your marketing efforts.

Let’s assume you own an eCommerce business. Here are the details:

You perform a CRO audit and find out there are multiple CTAs that split the focus of your audience, leading to a lower conversion rate. You fix the CTA and focus the attention of the visitors, leading to a 0.5% increase in the conversion rate.

A 0.5% increase in conversion rateled to a 50% boost in your monthly revenue.

In a nutshell, a CRO audit is not something optional. It’s an essential process that every online business, regardless of its domain, must take advantage of.

The right time to conduct a CRO audit includes events like a sudden drop in conversion rates, website launches, upgrades, noticeable changes in conversion rates, and before promotions.

A CRO audit during these moments helps identify issues, optimize performance, and maximize ROI. Regular audits ensure your strategies remain effective and responsive to user behavior changes.

1. Sudden fall in conversion rates

Everything was fine.

But you suddenly noticed a drop in your conversion rates. Something is definitely wrong.

What should you do?

It’s time to perform a CRO audit.

A CRO audit will help you identify the potential reasons behind the decline in performance. Once you identify the problem, you can work on possible solutions and bring your conversions back up.

Pro Tip: Act the moment you notice a slump. This will help you minimize the impact on your bottom line.

2. Website launch

Launching your website or a new line of products? Wait for the results of your CRO audit.

Performing a CRO audit a few months before the launch of your website/product can help you identify potential issues early on. This will allow you to maximize your ROI and avoid any blunders.

Pro Tip: After the launch of the website/product, you’ll see a lot of traffic. However, it will slowly subside. Performing an audit at that time can:

3. Website upgrade

It’s common for businesses to make changes (web copy upgrade, a different theme, new features, etc) to their website every now and then. However, these changes can impact your conversion rate.

So, if you’ve recently made changes to your website, it’s advised to conduct a CRO audit. This will help you determine performance differences, if any.

Pro Tip: Prioritize the changes that might have a direct impact on conversions like CTAs, navigation over less important ones.

4. Change in conversion rate (high or low)

Earlier, we said you must perform an audit when your conversions drop. But what’s even better is to perform an audit whenever you notice a change (rise or fall).

Here’s why:

Pro Tip: make sure you review historical data to determine if the change is a temporary fluctuation or a part of a broader trend.

5. During promotions

Conduct a CRO audit If you’re about to launch promotions like discount offers. You’re expecting a lot more traffic than usual, and the same goes for the conversion. So, you’d want everything from the content and design to CTA placement to be perfect. And that’s something you can ensure with the help of a CRO audit.

Pro Tip: Include a load test in your CRO audit to ensure your site can handle the extra traffic seamlessly.

Now that you know what a CRO audit is, its importance, and the right time to conduct one, let’s learn how you should prepare for a CRO audit.

Preparing for a CRO audit involves setting clear goals, gathering relevant data, analyzing marketing efforts, and identifying key conversion pages. By prioritizing actions based on potential impact, you can focus on areas that directly enhance your website’s performance.

In the following sections, we'll dive deeper into each of these steps to help you get ready for a successful CRO audit.

1. Define your goals

What do you want? More sign-ups? Traffic? Sales? Leads? Defining your goals and objectives will help guide your audit strategy and decide what CRO metrics you need to track.

Say you want to improve traffic on your eCommerce website. The metrics to track will include organic traffic, referral traffic, etc.

And if your goal is to improve sales, the metrics you’d want to track will be conversion rate and average order value.

2. Collecting data (quantitative and qualitative)

The next step in the process is collecting data relevant to your website’s performance. When it comes to quantitative data, you need to collect:

Tip: To collect this data, you can rely on Google Analytics and Hotjar (visualize user behavior with heatmap).

And for qualitative data, you can go for customer feedback. This will help you understand the “why” behind the users’ behavior.

To gather qualitative data, you can review customer feedback such as reviews or comments.

Tip: to collect feedback, you can use tools like Zonka Feedback and Hotjar.

The entire point of gathering the data is to identify the potential pain points of the users.

3. Analyze your marketing efforts

You need to analyze your existing marketing efforts to understand how effective they are in driving traffic and conversions:

Here’s how you can approach it:

4. Where are the conversions happening?

Imagine you start your audit but you don’t know which pages to focus on. Would this type of audit make any sense? Of course not!

You’d want to focus your efforts on the pages where the real action (conversions) is. Examples of pages where conversions happen include product pages, payments pages, lead gen forms, landing pages, etc.

5. Prioritize your action

Let’s say your goal was to increase the conversion rate by 25% within the next 6 months.

And you identified these areas for improvement that could make a difference:

Now, you could start with the product page or the email sign-up issue. After all, only if more people add your product to the cart and sign up for your newsletter will you be able to nurture them further.

However, by doing that, you’d miss out on direct revenue. Why?

Because you’re not prioritizing the checkout issue. As it’s the last step before the money gets credited, you should first fix the checkout issue.

That’s why prioritizing your actions is crucial.

Now that you have all the prerequisites ready, it’s time to finally dive into the most interesting part of this article: conducting a CRO audit.

To conduct a comprehensive CRO audit, you need to set clear goals, break down conversion targets, select relevant metrics, and focus on high-priority pages. Key steps include evaluating landing page design and copy, analyzing the conversion funnel, understanding user behavior, forming hypotheses, and conducting A/B tests.

Continuous monitoring and optimization ensure sustained growth and improved conversions. Here is a step-by-step process to help you conduct a comprehensive CRO audit:

1. Decide the goals of your CRO audit

Yes, we talked about this in the previous section as well. However, it is essential to consider how important it is to define your goals.

Answer this: What are you planning to achieve with this CRO audit? What are your conversion targets? The answer to these questions depends primarily on:

Remember, the goals you set for your CRO audit, directly impact what you do and what metrics you track. So, make sure the goals you set align with your overall business objectives.

For instance, if your business objective is to increase revenue from your website, the goal would be boosting the percentage of people completing the checkout process.

And based on the above goal, here are the metrics you’ll be tracking:

2. Breaking down your conversion targets into actionable steps

You’re done setting the goals and objectives. What now? Now, you need to get more specific or granular with your conversion targets. Why is this important?

Say your goal is to double the conversions in the coming 3 months. While possible, doubling the conversion rate can sound pretty overwhelming.

Afterall, conversions could mean a lot of things in different industries. For instance, in e-commerce, conversion could be a purchase, and for SaaS, it could be a trial signup.

So, it’s important to get specific with your conversion targets by breaking down the primary goal into smaller achievable chunks. Here’s how:

3. Choosing the right metrics for your CRO audit

You should choose the metrics based on two things:

Here are some conversion metrics worth monitoring:

So, these were some general KPIs. Let’s also discuss some industry-specific KPIs:

CRO Audit Example for E-commerce Websites

Goal: Drive product purchases and boost revenue from sales.

KPIs

CRO Audit Example for SaaS Providers

Goal: increase trial signups, onboard users, and convert them into paying customers.

KPIs

Lead Generation Platforms

Goal: Generate quality leads for a sales team or further nurturing.

KPIs

CRO Audit Example for Content Sites

Goal: bring user engagement, boost page views, and potentially increase subscriptions or ad revenue.

KPIs

4. Identify and focus on high-priority pages

Identify the pages with high traffic volume that act as crucial touchpoints in the customer journey. Because these are the pages that have the maximum impact on your conversion rates. And you’d obviously want them to perform.

So, skip TOFU pages and zero in on high-priority pages like demo sign-ups, free trials, or whatever is relevant to your business goals.

5. Landing page evaluation (don't skip this)

Your goal is to convert visitors into paying customers. That’s what all marketers wish to achieve. To achieve this, you have to make sure that your landing page is marvelous.

Think of this part of your CRO audit from a customer’s perspective, i.e., how would a customer perceive everything? This will help you optimize your landing page better. Here’s what you need to do:

Analyze the landing page design

Your landing page is supposed to bring you conversions, provided:

How would you know for sure? Ask yourself these questions, and you’ll know for sure:

Technical issues in your landing page?

Finding answers to these questions can be overwhelming. But you’d be surprised to find out how effective it can make your landing page

Evaluate the landing page copy

Your landing page copy has one purpose: to persuade visitors to take the desired action. And if it’s not up to the mark, no matter how good your product or service is, you won’t get any conversions.

Here’s what you need to keep in mind when evaluating your landing page copy:

Bonus: Is your landing page message in sync with your ad?

Imagine you see a quirky ad with amazing graphics and copy making you want to click. We all have seen these types of ads. You end up clicking on the ad only to find out it’s a completely different story on the landing page.

What would you do? Of course, bounce off!

You bounced off because you did not get what you were promised.

So, when evaluating your landing page, make sure the ad copy and the landing page’s messaging are in sync. (we know an amazing CRO tool that’ll help you sync and personalize your messaging on all ad platforms and landing pages)

6. Conversion funnel analysis

A conversion funnel is what your visitors go through to transform into paying customers - starting from the awareness stage and ending with the decision-making stage.

Analyzing your conversion funnel as a part of your CRO audit can reveal important insights into user behavior and potential issues.

Let’s say, upon analyzing your funnel, you identify a dropoff between the conversion and subscription stages. Now, you know where the problem is. You can run A/B tests, fix the issue, and instantly boost conversions.

7. Understanding user behaviors

It’s time to understand user behavior. This step helps you skip the guesswork and understand:

You can leverage the goal conversions feature in Google Analytics and track events to closely analyze user behavior.

If you mix these insights with those from funnel analysis, you can:

All this makes your optimizations more powerful.

8. Form a hypothesis

By now, you’ll have some good data. And you might even have identified the potential problems and their solutions. Gather your data and form a hypothetical theory that explains what is happening, why, and what can be done to optimize the performance.

Here’s an example: Say you notice that users are dropping off at the checkout stage. You hypothesize that a complex checkout process may be causing that frustration. To test your theory, you might simplify your checkout steps or offer a guest checkout option to further reduce friction.

Once you have your hypothesis ready, go for an A/B test.

9. A/B testing your hypothesis

A/B testing is the final step of your CRO audit. It’s finally time to put your theory to the test and clear all your doubts.

The result of an A/B test will help you determine if what you were thinking was right. And you can then use these insights to improve further. Here are some elements you’d want to test:

Once you’re done with your A/B test, you’ll get to know if what you thought was right or not. Based on the results you get, you can create further theories and test them until you achieve complete truth.

Pro Tip: A/B testing is not worth the effort without the right tool. Fibr AI is an AI-powered personalization platform that can help you perform comprehensive A/B tests, craft and optimize landing pages, and create tons of landing page variations within seconds.
