How do I start with A/B testing if I've never done it before?

As a new e-commerce entrepreneur, I'm overwhelmed by the concept of A/B testing. I know it's crucial for improving conversion rates, but I have no idea where to start. I've heard terms like 'statistical significance' and 'conversion optimization' but find the whole process intimidating. I want to understand the basics, learn how to set up my first test, and avoid common beginner mistakes that could waste my time or provide misleading results. What are the fundamental steps to implement A/B testing in my online store, and how can I ensure I'm doing it correctly?
