Whether you're a developer or a business owner, this guide by Ben Bond, a seasoned WordPress consultant, will walk you through the top 10 tips for developing custom WordPress themes that not only look great but also perform seamlessly.

1. Understand Your Audience and Goals

Before diving into coding, take a moment to define who your theme is for. Who will use it? What are their needs?
