How do you convince WooCommerce clients you're an expert (before they hire you)?

One thing I've noticed is that many businesses don't actually need a "WordPress developer"—they need someone who understands how WooCommerce works under real business conditions.

After working on WooCommerce projects, I started noticing the same patterns behind successful stores.

Some things experienced WooCommerce developers usually get right:

Store speed that doesn't drop during traffic spikes.
Checkout optimization that reduces abandoned carts.
Secure payment gateway integrations.
Custom functionality without relying on dozens of plugins.
SEO-friendly product and category structures.
Scalable code that's easy to maintain.

I put together a practical guide explaining what separates an average WooCommerce developer from a true WooCommerce expert.

If you're planning to build, redesign, or scale an online store, I'd love to know:

What's the biggest challenge you've faced with WooCommerce?

I'll answer every question in the comments.
