What Characteristics Make a Great CRO Agency?

Although it is necessary to select a CRO Agency to help increase your conversion rate, it’s hard to choose the right one out of the vast options available; moreover, choosing the wrong CRO agency can cause excessive waste of investment.

Here are the four characteristics that make a great CRO agency:

  1. Dedicated CRO Services
  2. Budget and Pricing
  3. Transparency
  4. Experience and Expertise

1. Dedicated CRO Services

 Many marketing agencies deliver various services at once; however, you need to hire a marketing agency that specializes mainly in the skills you need for your e-commerce business and maximizes results by applying the best strategies.

For instance, if you want to increase your conversion rate, you should hire a CRO agency, but if you want to increase the website traffic, you should choose an SEO agency instead.

2. Budget and Pricing

Hiring a CRO agency is less expensive than building an in-house team, but you should consider paying for three months of services in advance. Therefore, if an agency clarifies that the charge is about $30.000 a month, you would better doubt it as the best choice. A good CRO firm can be extremely profitable, but it is the wrong choice if it isn’t affordable for you.

3. Transparency

A great CRO agency embraces transparency as a crucial part of leading to success. It begins at the first meeting just before the beginning of the optimization process. To trust a CRO agency, you need to know their optimization roadmap. Moreover, if a CRO firm promises to increase the conversion rate in less than a month, don’t choose it for your partnership because conversion rate optimization takes time to reach desired results. Here, a transparent CRO agency’s activities for its clients are listed.

What does a transparent CRO agency do for its clients?

  • Conducting weekly status meetings
  • Updating clients with occasional data report
  • Responding to clients’ questions about the CRO program
  • Discussing different testing plans
  • Receiving feedback on their work
  • Accepting mistakes and being honest with clients

4. Experience and Expertise

Experience and expertise are essential factors for a great CRO agency. Hiring an agency with years of experience and many achievements in optimizing conversion rates increases your chance of fulfilling your goals. You should know that developing expertise in the field of CRO doesn’t happen overnight, so you should look at the firm’s achievements in the last five years or even more. Besides, a highly experienced agency can predict possible issues and the true way to deal with them. They easily recognize your website’s pain points and use a special CRO program to solve the problem faster. To figure out if a CRO agency has enough experience and expertise, examine their:

  • Testimonials
  •  Reviews
  •  Case studies
  • The current condition of the CRO agency’s website regarding CRO implementation 
  • The current condition of the previous clients’ websites regarding the effectiveness of CRO applied by the agency

How to Choose the Right CRO Agency for You?

As discussed earlier in this article, marketing agencies specialize in different marketing skills such as SMM, SEO, PPC, etc. Therefore, before hiring a CRO agency, you must know your goals, desired outcomes, and your exact needs based on which you represent a business brief to the CRO agency. Although you are about to hire a CRO agency to optimize the conversion rate of your company, it would be better to give them a complete brief that:

  • Presents all the relevant considerations to help the agency fully understand the situation,
  • Defines the company’s needs and goals,
  • Clarifies what parameters you want to track,
  • Determines what parts of your website need conversion rate optimization, e.g., the home page, a special landing page, a product page, etc.


Otherwise, the CRO agency has to test different methods to discover the problem you might already know, increasing the cost of services. Then, you can choose the company that suits your situation and specializes in your desired services. It is better to choose a CRO agency that has previously worked with clients whose businesses were similar to yours.

Questions before choosing a CRO agency:

Since you are looking for a long-term partnership, you should take your time and ask yourself the following questions before making a brief and choosing a CRO agency:

  1. What part of my business doesn’t work well?
  2. What is the solution for reaching more website traffic?
  3. What do our clients say in comments or reviews on YouTube, Facebook, etc.?
  4. What activity is the most profitable one for our company right now?
  5. How much monthly budget can I allocate for this work?

So answering the above questions helps you determine what should be optimized. Therefore, you know what services you need and then look for CRO agencies specializing in those special areas.

 Frequently asked questions:

What is a CRO agency?

A CRO agency has a team of CRO professionals whose duty is to ensure all conversion rate optimization aspects are fully accomplished; therefore, the client reaches its main goal of making more profit.

What is the CRO process?

CRO refers to optimizing clients’ websites to encourage more visitors to do a determined action. It collects quantitative and qualitative data to increase the percentage of visitors who do the desired action.

Why is CRO important?

CRO allows you to produce more profit while other factors, such as website traffic or ad spend, are still the same. You can reach more customers and develop your business by optimizing your conversion rate.

What are the main elements of CRO?

The main elements of CRO help you reach your goals, such as increasing your online sales or email subscription. However, even if you want to outsource it, knowing the following elements is good for tracking your conversion rate optimization and ensuring whether the agency is working effectively or just taking advantage of your lack of related knowledge in this field. That is why we recommend you benefit from the following four overlapping elements of CRO:

  • conversion research
  • website persuasion
  • user experience (UX)
  • A/B Testing & Personalization
1. Conversion Research:

To optimize your website’s conversion rate, you need to know why your visitors don’t take your desired action. For example, there might be broken links, website bugs, or a misleading design on the website. Therefore, as one of the essential elements of CRO, conversion research comes into play.

What is conversion research?

Conversion research is an inseparable element of CRO; it uses behavioral analytics tools to gather ideas for improving conversion rates.

What are behavioral analytic tools used through conversion research?

A list of the most powerful tools used to identify pain points of your website from the viewpoint of your customers are mentioned as follows:

2. Website Persuasion:

Running a website doesn’t guarantee converting a huge number of visitors to loyal customers. To convert more potential visitors, you should use persuasive copywriting that emphasizes the values of your services or products to encourage users to stay on your website, as well as the six principles of influence:

  • Reciprocity,
  • Commitment/consistency,
  • Social proof,
  • Authority,
  • Liking,
  • Scarcity.
3. User Experience (UX):

If your website has a poor layout and navigating through it is confusing for visitors, we call it a bad user experience. By improving your website user experience (UX), visitors find it easy to stay longer on your website, and your chance of having them as customers will consequently increase.

4. A/B Testing & Personalization:

A/B testing or split testing can optimize your website’s conversion rate. Through A/B testing, two variants of the same web page are shown to different audience segments simultaneously to conclude which of them leads to more conversions. For instance, one variant might include an image in the right corner of the page while the other displays the image in the left corner of the page. Then, according to the comparison results, it’s decided to put the image on the web page to attract visitors’ attention easily and increase the chance of a conversion.
