Store Setup: Domain, Payments, Shipping & Taxes (Items 1–5)
Place a test order using every payment method you've enabled — not just the primary one. I've seen stores launch with a broken PayPal integration that went unnoticed for weeks because the team only tested credit cards.
Design & UX: Theme, Mobile, and Navigation (Items 6–10)
Load your store on a 4G connection using Chrome's network throttling. If any page takes more than 3 seconds to become interactive, you have a speed problem that needs fixing before launch.
Products: Descriptions, Images, Variants & SEO (Items 11–15)
Search Google for your main product keywords and look at what the top-ranking competitors include on their product pages. If they all have sizing guides, comparison charts, or ingredient lists and you don't, add them before launch.
Legal: Privacy, Terms & GDPR Compliance (Items 16–18)
Run your store through a GDPR compliance checker like Cookiebot's free scan before launch. It crawls your site and identifies every cookie and tracker, showing you exactly what needs consent management.
Marketing Infrastructure: Email, Social & Analytics (Items 19–21)
Send yourself through every automated email flow before launch. Check that discount codes work, links point to the right pages, and images load correctly. A broken welcome email with a dead discount code is worse than no email at all.
Testing: Orders, Checkout & Speed (Items 22–24)
Recruit 3–5 friends or family members who weren't involved in building the store. Give them a task — 'Buy the blue medium t-shirt' — and watch over their shoulder without helping. Fresh eyes catch what yours have gone blind to.
Launch Day: DNS, Go-Live & Post-Launch (Item 25)
Schedule your launch for Tuesday through Thursday morning. Avoid Mondays (you're catching up), Fridays (support coverage is thin over the weekend), and weekends. If something breaks, you want a full business day to fix it.
Conclusion
Key Takeaways
- 01Test every payment method with real transactions before launch — broken payment integrations are the most expensive oversight
- 02Over 72% of e-commerce traffic is mobile — test on real phones with real network conditions, not just browser simulations
- 03Build your email capture and automated flows before launch so you monetize traffic from day one
- 04EU stores need GDPR-compliant cookie consent, an imprint, and VAT included in displayed prices — missing these carries legal risk
- 05Launch on a Tuesday through Thursday morning so you have full business days to address any issues that surface
