You've decided to sell online. Maybe you're moving a brick-and-mortar business to the web, or maybe you're starting fresh with a product line you believe in. Either way, the gap between "I want an online store" and "my store is actually ready for customers" is bigger than most people expect.
The technical setup is only part of it. Plenty of stores launch with a working checkout but no shipping policy, decent product pages but no SEO strategy, or a beautiful homepage but no way to track whether anyone's buying.
This checklist covers the things that actually matter before you hit publish — organized by what will cost you money if you skip it.
The Foundation
1. Your Own Domain Name
Don't launch on a subdomain like yourstore.shopify.com. A custom domain (like yourstore.com) costs $12–20/year and is the single cheapest credibility boost you can get. Customers trust branded domains more, and it matters for SEO.
If your exact .com is taken, consider .co, .shop, or .store — but avoid anything too obscure.
2. SSL Certificate (HTTPS)
This isn't optional. Every page on your store should load over HTTPS. Without it, browsers will show a "Not Secure" warning that will kill your conversion rate instantly. Most modern hosting platforms include SSL for free — if yours doesn't, that's a red flag about the platform itself.
3. Mobile-First Design
Over 60% of e-commerce traffic comes from mobile devices, and that number keeps climbing. Your store needs to work flawlessly on phones — not just "render" on phones, but actually be easy to browse, search, and check out on a small screen.
Test the entire purchase flow on your own phone before launch. If you have to pinch-zoom at any point, it's not ready.
Products and Payments
4. Product Pages That Actually Sell
Each product page needs:
- Multiple high-quality images — at least 3 per product, showing different angles and scale
- A clear, specific description — not just features, but why this product matters to the buyer
- Price displayed prominently — no "contact for pricing" unless you're selling enterprise software
- Stock status — if you can run out, show availability so customers don't order and wait
- Shipping information — or at least a link to your shipping policy
A weak product page is the #1 reason visitors browse but don't buy. This is worth spending real time on.
5. Payment Processing
You need to accept cards at minimum. Most stores should also support:
- Digital wallets — Apple Pay, Google Pay. These reduce checkout friction significantly on mobile.
- Buy now, pay later — services like Klarna or Afterpay can increase average order value by 20-30% for products over $50.
Set up a test transaction before launch. Actually buy something from your own store and make sure the confirmation email arrives, the order shows up in your dashboard, and the charge appears correctly on your statement.
6. Sales Tax Configuration
This catches more new store owners off guard than almost anything else. Sales tax rules vary by state (in the US) and by country, and getting them wrong can create legal and financial headaches down the road.
If you're using Shopify or a similar platform, enable automatic tax calculation. If you're on a custom build, integrate a tax API like TaxJar or Avalara. Don't try to hardcode tax rates — they change.
Trust and Legal
7. Shipping, Returns, and Refund Policies
Nearly half of online shoppers check a store's return policy before they buy anything. If you don't have one — or if it's buried in a PDF somewhere — you're losing sales.
Your policies should be:
- Easy to find — linked in the footer, on product pages, and in the checkout flow
- Written in plain language — no legalese
- Specific — "30-day returns, no questions asked" beats "returns accepted per our discretion"
Be honest about shipping times too. If it takes 7–10 business days, say so. Overpromising and underdelivering is worse than setting accurate expectations.
8. Privacy Policy and Terms of Service
These are legally required if you collect any customer data (and you will — emails, addresses, payment info). Most e-commerce platforms offer templates, but you should customize them to reflect your actual practices.
If you're selling to EU customers, you also need GDPR compliance — including cookie consent banners and data deletion requests.
Discovery and Growth
9. Basic SEO Setup
If nobody can find your store on Google, it doesn't matter how good your product pages are. Before launch, make sure:
- Every page has a unique title tag and meta description — including product pages
- Your URLs are clean and readable —
/products/blue-running-shoesnot/products/item-38291 - Images have alt text — this helps with Google Images traffic and accessibility
- Your site loads fast — Core Web Vitals matter for e-commerce SEO especially
A framework like Next.js gives you a head start here — server-side rendering means Google can crawl your pages more effectively, and automatic image optimization handles one of the biggest performance bottlenecks.
10. Analytics From Day One
Install Google Analytics (or a privacy-friendly alternative like Plausible) before you launch — not after. You want data from your very first visitors.
At minimum, set up tracking for:
- Page views — which pages get traffic
- Conversion funnel — where do people drop off between landing and purchasing
- Traffic sources — where your visitors are coming from
- Revenue — tie purchases back to your analytics so you can calculate actual ROI on marketing
If you launch without analytics, you're flying blind. Every day without data is a day you can't learn from.
11. Email Capture
Even if you're not ready to run email campaigns yet, start collecting emails from day one. A simple "Get 10% off your first order" popup can capture 3-5% of visitors.
These email addresses become your most valuable marketing channel over time — you own the list, unlike social media followers that can disappear overnight if an algorithm changes.
12. A Launch Marketing Plan
"Build it and they will come" has never been true on the internet. Before launch, have a plan for driving your first 1,000 visitors:
- Social media announcements — tell your existing audience
- Email to your personal network — friends, family, former colleagues
- Paid ads budget — even $10/day on Google Shopping or Meta can validate demand
- Content marketing — blog posts targeting keywords your customers are searching for
You don't need all of these, but you need at least two or three. A store with zero traffic is just a beautiful page nobody sees.
Before You Hit Publish
Run through this quick final check:
- [ ] Place a test order and verify the entire flow (payment, confirmation email, order in dashboard)
- [ ] Check every page on your phone — especially product pages and checkout
- [ ] Click every link in your navigation, footer, and CTAs
- [ ] Verify your shipping rates are correct for at least 3 different addresses
- [ ] Make sure your 404 page exists and looks intentional, not broken
- [ ] Test your site speed — aim for under 3 seconds on mobile
