Principles
Because conversion optimization is a broad field, almost every conversion optimization specialist has his or her own ideas about the best principles to get the maximum result from a collaboration.
Connecting to the organization
Every organization has a different level of 'digital maturity'. Connecting to this is very important. For example, a website analysis is often better suited to a slightly less mature website and A/B testing is usually better suited to a more mature website. Issues such as available employees and budgets also play a role in which activities will yield the greatest return.
Communicate clearly
Successful conversion optimization is created by collaboration between several people. Consider, for example, managers, developers, analysts, and psychologists. Clear communication between these different people is therefore necessary to achieve the best results.
Thinking from the visitor's perspective
Ultimately, it is the visitor who decides whether or not to make a purchase, request or donation. This is why it is important to think from the visitor's perspective and stay away from 'tricks' to entice them to convert. Things like user tests can help with this.
Working with an eye for detail
If you do something, do it well. Experience shows that tackling a problem at its root usually has a much greater effect than treating the symptoms over and over again. For this reason, there is a focus on pursuing a scientific standard in the work. Consider things such as well-written code, tests that are reliable and valid, and visually attractive reports.
CSR
Corporate Social Responsibility (CSR) plays an important role within this organization. The items below are an indication of how Theo runs a future-proof conversion optimization company.
- Planting trees: For every new customer he plants 10 trees via TreesForAll. Every collaboration starts with a positive impact on the climate, biodiversity, and a healthy living environment. The trees are planted in the Netherlands and abroad.
- Low consumption: The company is completely paperless and uses green energy. In addition, almost all meetings take place digitally to avoid unnecessary transport. At times when travel is required, this is done by bus and train.
- Sustainable website: An analysis with Website Carbon Calculator shows that this website produces only 0.08 grams of CO₂ per page view, which is cleaner than 92% of the tested websites. The website also runs on sustainable green hosting.
- Knowledge sharing: Knowledge is shared about sustainable conversion optimization on our own blog and social media channels. Theo also presents at national and international conferences on topics surrounding sustainability, such as sustainable marketing.
- Sustainable customers: We are specifically looking for collaborations with more sustainable companies. As a result, well-known green organizations such as Solarfields, Natuurhuisje, Pieter Pot, Greenchoice, and Well Water are among the satisfied clients.
- Charities: Various charities such as Longfonds and Hartekind have been helped on a voluntary basis with optimizing their websites. The resulting findings have been bundled in an article about CRO for charities.
Besides work
In addition to his work as a freelance conversion specialist, Theo is involved in various matters. He enjoys playing chess or painting landscapes in watercolor. He also likes to get to the bottom of things, for example how to make even healthier green smoothies.
Theo has been with his girlfriend Lisanne for more than 10 years. They share a passion for (among other things) train travel and this has already taken them to beautiful places, such as the Swiss Alps and Swedish Lapland.
