CRO: What it is and how to apply it to your marketing strategy

Index Content

CRO or Conversion Rate Optimisation is a digital marketing strategy that serves to optimise the conversion rate of a business. It encompasses different methodologies to improve the performance of a brand. These techniques seek to increase user interaction with the website. Therefore, they are also beneficial for other actions such as generating more web traffic or consolidating the customer-company relationship. Its operation is based on defining a CRO strategy and developing tactics focused on testing, data analysis and customisation. Subsequently, new procedures are reviewed, reworked and implemented to obtain the best results.

The conversion rate is the indicator that determines the effectiveness of your website. It reveals the percentage of users who have come to perform an action. This can be from completing a purchase process to downloading an ebook. In other words, the strategy focuses on getting visitors to perform an action, not on generating more traffic. To develop this technique you must understand the behaviour of users with the website; tools like Google Analytics facilitate its measurement. SEO and CRO are complementary strategies since the first aims to position the website in the top search engine results and the second ensures that the traffic generated is translated into potential customers.

Call to action

CTAs should be eye-catching and catch the user's attention. They should clearly express the action to be performed by the visitor with imperative verbs such as "Register" or "Download".

Providing confidence and guarantee of performance in the products offered will improve the visitor's relationship with the brand. The main objective is to encourage them to take an action.croTips to improve your CRO

4 steps to implement a CRO strategy

1. Analyse the behaviour of users with the website

To start designing a CRO strategy, you must define the KPIs you want to achieve. After knowing them, you must calculate the current conversion rate of the website and collect information about its content. Google Analytics provides this type of information and reveals at what stage of conversion users leave the page.


Similarly, heatmaps help to understand what actions visitors perform on the website and represent them visually with a range of colours. Hotjar is an essential tool for creating heatmaps.cro

The information can be complemented with qualitative data by conducting questionnaires or user interviews.

2. Designing the ideal user journey

By obtaining information about the user's journey through the website, you can begin to design the ideal user journey to achieve a conversion. You should define the stages of the sales funnel and focus on those that will benefit your business the most.

3. Optimise the website

Depending on the pre-designed ideal journey, a series of elements are placed to facilitate the user's conversion. These can redo, delete or add content, images, videos, information or improve the UX. In digital marketing, calls to action are essential to achieve conversion. Adding floating or static notification bars serves to obtain emails, show irresistible offers or inform the visitor about something new. Banners can fulfil the same function as the bars. Pop-ups or pop-up windows interfere with the content of the site to impact the user.

4. Analysing data

Monitoring website activity will help to check the effectiveness of CRO, comparing the initial data with the data obtained after implementation.
