The blank page is the hardest part! My process is to start with a content inventory, even if it's just sticky notes on a wall. I list every piece of content or functionality needed, then group them into logical clusters based on user goalsthese become your top-level categories. For the actual structuring, I highly recommend a guide focused on creating a site map that walks through techniques like card sorting and shows how to visualize the hierarchy. It emphasizes that a sitemap is a communication tool to align your team and stakeholders on the site's structure before any design begins, which saves countless hours later.
