CRO Frequently Asked Questions

  • Conversion rate optimisation, often abbreviated as CRO, is the process of increasing the number of users on a website completing a desired action. This action may be a macro event such as the main conversion action onsite or a softer micro event that helps move a user along the decision making journey.

    A desired action could be to buy a product or service, fill out a form, or add a product to a cart.

    However there is much more to conversion rate optimisation. For example, CRO is misleading. A user will not just look to optimise conversion rate. However this is one of the most common macro events a website is optimised towards and has been known as this specifically up until recently. Now more and more specialist CRO testing companies refer to the service as ‘experimentation’ as this is really what CRO is all about.

    It is the process of using quantitative and qualitative research to create a hypothesis. Then using that hypothesis to create and run experiments that evidence change. This is what conversion optimisation is really all about.

  • A CRO agency, or a conversion rate optimisation agency, is a group of experimentation specialists that help clients understand their quantitative and qualitative data. Prioritise opportunities then run a controlled and scientific approach to experimentation and change for that company and its customers/website. The aim may be to increase the number of users completing a desired action on a website, to enhance conversions, leads, or revenue.

    A good CRO agency goes beyond tactics and ‘best practice’ and finds the best solutions for that client. They create a culture of evidence-led change and ‘customer first’ improvements.

    Here at Converted, we’re a conversion rate optimisation agency that has helped many companies increase their conversions, leads, and revenue through optimising their websites. One of our clients, the London Travel Clinic, saw a 163% increase in the conversion rate of visitors to bookings. Likewise, an eCommerce website, Badgemaster, saw a 75% increase in goal inquiry rate.

    These real world examples are just two of a long line of clients who have seen their company improve the core KPI’s using our CRO services.

  • A CRO specialist like Converted optimises a website or landing page to increase the number of people conducting a desired action, such as buying a product.

    In practice, we analyse 25 elements of a business to audit and create a hypothesis on what’s not working and how we can improve it. We will then design and implement changes while thoroughly testing to see what is the most effective method for increasing conversions.

    We use leading testing technology, AI, and quantitative and qualitative data analysis to do this. We’ll then report our findings back to you and help improve your KPIs.

  • We have created a useful article to help you understand how to calculate your conversion rate. You can find this here

    We also have created specifically for CRO testing the following calculators that will help you run more controlled experiments. These are:

    Test Duration Calculator, which helps you understand how long your conversion optimisation tests should last.
    CRO Test Significance Calculator, which helps you understand if the data you have captured on existing CRO test has reached a significant point.
    But if you’re a B2C business and want an affordable CRO agency then get in touch and we’ll do the hard work for you!
