Do you recognize this?

  • There are recurring questions about the behavior of visitors on the website
  • Tools like Hotjar have been around for a while, but are hardly used
  • In practice, many decisions are still made 'by feeling'

And want the following?

  • Someone with knowledge and experience of visitors and research
  • Who knows how to uncover new concrete insights in a short time
  • And thus help make the organization more data-driven

Highlighted benefits

Flexible approach → Customized help

Sometimes plans, expectations and needs simply change. Dealing with this flexibly creates the greatest added value for the customer. For example, training or coaching in-house specialists is also possible.

Experienced consultant → Clear communication

I now have decades of experience as a consultant. In addition to excellent project management skills, this also ensures that I can communicate well with stakeholders at all levels. Explaining findings to directors, developers, or obstacles is therefore no problem.

Hands-on experience with tools → Fast and reliable insight

I have extensive experience with tools such as Google Analytics and Hotjar. This means that minimal valuable time is lost finding out what the (im)possibilities are with these tools for your website.

Frequently asked questions

How does CRO contribute to data-driven working?

By nature, CRO works very much from data rather than from gut feeling. Working with a CRO consultant automatically ensures that more attention is paid to matters such as data quality and research.

What about the implementation of the advice?

If necessary, consultation will take place with your developers about the implementation. After all, they know the code best and will know how the advice can be implemented as best as possible on the website or webshop.

What tools are needed for CRO research?

Basically, a tool for web analysis (such as Google Analytics) and a tool to view visitor behavior (such as Hotjar) are particularly important. In addition, other tools may provide added value in specific cases.

How important is good data quality?

The quality of the data determines how reliable and valid an analysis will be. If the data in Google Analytics is not clean (for example due to problems with tagging, tracking, filters, etc.) then it is very difficult to work with it. Therefore, ensure that data quality is checked and kept high.

Need a lot of data for CRO research?

The more relevant data, the more complete the picture from the CRO research will be. Keep in mind that the quality of the data is often more important than the absolute quantity. The presence of additional data (such as by using Enhanced Ecommerce) can also help with this.
