November 17, 2022 — It is estimated that the digital world currently accounts for about 3% of global greenhouse gas emissions. To put this number in perspective, that’s more than the entire global aviation industry combined. These emissions are largely caused by the energy required by end-user devices and the data centers that process data on the Internet. Therefore, every page on a Website that you view creates small amounts of greenhouse gas emissions. Fortunately, there are ways in which these emissions can be reduced by Website owners. For example, you can think about improvements like green hosting and optimization of things like loading speed, fonts, redirects, and images. This practical and applied session will cover several examples that attendees can apply immediately the next day to make their Websites more sustainable.

February 25, 2020 — The average conversion rate of a website is only 2%. Do you know why the other 98% of your visitors didn’t convert? Do you even know what made the 2% convert with you instead of your competitors? Getting answers to the questions above is one of the key aspects needed to increase your conversion rates. But how can you get these questions answered?

In this talk, I will explain three methods to help you with this. For each method, estimated time/cost, suggested tools and recommended tasks/questions will be provided to help you get the most out of your research efforts.

January 8, 2018 — These days, everyone is using the fastest hosting, superior caching, the minimal amount of plugins, etc. (right?).

Some examples include using image compression, removing dynamic Google Maps, optimizing your fonts and using lazy loading. For these, and many other issues we’ll provide actionable fixes, so you can start improving your website tomorrow.

October 14, 2017 — Je kunt nu twee kanten op (welke met real-life voorbeelden en bijpassende tools in de presentatie zullen worden uitgewerkt):

1) Niet geadviseerd: zorgen dat je toch kunt gaan A/B testen. Denk hierbij bijvoorbeeld aan het inzetten van SEA of SEO om je aantal conversies per maand te verhogen. Ook kun je denken aan een lagere significantie grens, varianten achter elkaar (in plaats van naast elkaar) neerzetten, grote veranderingen per keer proberen, een focus op micro conversies, etc.

2) Wel geadviseerd: jezelf eerst richten op methodes die ook bij minder verkeer werken. Dit zijn bijvoorbeeld user testing, expert reviews en surveys. Ook je web analytics data of gegevens voortkomende uit mouse tracking of formulier analyse kunnen hier erg inzichtelijk zijn. Hoewel het verzamelen van deze bevindingen niet per se voldoet aan de wetenschappelijke normen, brengen ze vaak wel kritieke pijnpunten aan het licht. Zeker ook door meerdere van deze onderzoekstechnieken te combineren, kun je een redelijk stabiele bron van verbeteringen samenstellen. Overigens is het zo dat ook websites met veel verkeer sowieso vanuit gedegen vooronderzoek hun variaties zou moeten bepalen, waardoor deze methodes bruikbaar blijven wanneer het aantal conversies is gegroeid.
