What Is Conversion Rate Optimization (CRO)?

In digital marketing, “conversion” refers to your customer performing a specific action.

For example, it could be buying a product, subscribing to a newsletter, filling out a form, or achieving your conversion goal.

Your conversion rate is the percentage of website visitors responding to your call-to-action prompt.

Conversion rate optimization (CRO) increases this percentage by learning your customers’ motivation, reservations, and buying patterns and marketing your products or services based on this information.

How Does CRO Work?

We can divide the CRO process into five steps.

Step 1: Research and Data Gathering

The research and data stage involves gathering information about the behavioral patterns of the people who visit your website.

Obtaining this information allows you to figure out the best optimization strategy for your website.

Some CRO tools used in this stage are Abobe Analytics and Google Analytics.

Step 2: Forming a Hypothesis

After researching and gathering quantitative and qualitative data, the next step in the CRO process is forming a hypothesis based on your collected statistical data.

The hypothesis typically involves estimating how much you can improve your CRO rate by making specific changes to your website.

Step 3: Prioritization

During the prioritization process, you’ll figure out the areas where your website is performing the worst so you can focus on the most severe issues first.

PIE, PXL, and TIR are some of the most popular prioritization frameworks.

Step 4: Implementation and Testing

The implementation and testing stage is essential to the CRO process.

It’s where you see if your hypothesis was correct.

The three main testing methods are A/B, split, and multivariate.

Step 5: Learning and Reviewing

In this final stage, you make permanent changes to the website based on your results.

What Are the Benefits of CRO?

There are several benefits of conversion optimization.

Here are the most noteworthy ones.

It Gives You Insight Into Your Customer Base

Every business needs to know its customer base, which is especially crucial in eCommerce.

You need to know the products and services your customers are interested in and the best ways to market to them.

You Gain More Profits

The primary purpose of conversion rate optimization is to turn the traffic from your website into sales.

In addition, CRO improves the user experience for your website visitors, which earns you more customers by leveraging the current amount of website traffic you receive.

It Allows You To Spend Less on Marketing Campaigns

As we mentioned, CRO leverages the current amount of people visiting your website.

That means you gain customers without needing to pay for a marketing campaign, effectively lowering your customer acquisition costs.

Does CRO Affect SEO?

Your search engine optimization (SEO) and CRO strategies should go hand-in-hand.

If your website visitors leave your website and return to the search page, then this reflects poorly on the SEO value of your site.

Having meaningful content that gives your customers what they need helps your SEO ranking.

The Difference Between Conversion Rate and Click-Through Rate

Your click-through rate is the percentage of people who visit your website from ads.

The metric helps measure the traffic to your website.

Conversely, the conversion rate shows how many people complete an action.

Let’s say someone clicks on one of your Google ads but doesn’t respond to any of your call-to-action prompts.

They would increase your click-through rate but not your conversion rate.

What Is a CRO Agency?

A CRO agency is a team of conversion rate experts who commit to increasing the profitability of your website and lowering your customer acquisition costs.

They carefully analyze your website and then develop strategies for improving your website conversions.

The conversion optimization experts at these agencies are intimately familiar with the conversion funnel and will help your business achieve your conversion goal.

What Do CRO Agencies Do?

CRO Agencies can significantly improve your conversion metrics.

What this improvement looks like varies based on your company’s needs, but the agency will devise a plan for you after discussing your goals and analyzing your website.

Generally speaking, CRO agencies increase your website’s revenue and create a better user experience (UX) for your customers, which improves your brand perception, reduces your customer acquisition costs, and increases your customer lifetime value.

They upgrade everything, from your website copy to your layout, for a better customer experience.

What CRO Services Do Agencies Typically Offer?

CRO agencies offer a wide range of services to ensure they can accommodate the varying needs of their clients.

These services generally include:

  • CRO strategy
  • Data analysis
  • Development and design
  • Reports on your conversion metrics
  • SEO services
  • UX optimization
  • Landing page optimization
  • Experience with web analytics tools
  • Copywriting

What Is the Importance of CRO Agencies?

CRO is an essential part of your business’s success.

If you don’t have an internal team of experts to develop your CRO strategy, it’s in the best interest of your company to work with an agency.
