Once you’re ready to commit to a real storefront, the core setup steps (Shopify or WooCommerce, the logic is nearly identical):

1. Choose a clean, fast-loading theme — avoid heavily animated templates; page speed directly affects conversion rate and your Module 7 SEO rankings.
2. Set up your product pages using the SEO structure from Module 7 from day one — retrofitting SEO later is far more work than doing it correctly the first time.
3. Configure shipping zones and rates matching what you confirmed with your supplier in Module 4.
4. Connect a payment processor (Module 6) and test a real transaction end-to-end before launch, including what the confirmation email looks like.
5. Install/verify Google Analytics tracking (Module 8) before you start sending any traffic — you cannot recover data from before tracking was installed.
