I collaborated with the CEO, Product Manager, and Software Devs. We had an assortment of data for click-through, bounce, and conversion rates that informed us on how our users were interacting with our website.
Because of our small team and limited resources, we did a lot of internal user-testing and design reviews. Google Optimize was what we used when we did A/B testing on designs. Our visitors ranged from 50k-80k per day which allowed us to get a decent sample of feedback whenever we implemented a design.
