Ecommerce Website Launch Checklist 2026: 60 Essential Checks

Launch day is the worst time to discover that your shipping rules charge the wrong amount, your payment gateway is still in test mode or your product pages are blocked from Google. Most of these problems are easy to prevent with a structured pre-launch review. This checklist brings together the checks we run before every ecommerce launch, grouped by area, with the research behind the most important ones. Why does a launch checklist matter? Because shoppers leave quickly when anything feels wrong. Baymard Institute's analysis of cart abandonment rate statistics puts the average documented online shopping cart abandonment rate at 70.22%, calculated from 50 studies.

Some abandonment is unavoidable, since many shoppers are just browsing, but Baymard's survey of US shoppers shows that a large share of it comes from issues a store can fix: Reason for abandoning during checkout (Baymard survey) Share of US online shoppers Extra costs too high (shipping, tax, fees) 40% Delivery was too slow 20% Did not trust the site with card details 19% Site wanted me to create an account 18% Too long or complicated checkout 17% Website had errors or crashed 17% Returns policy was not satisfactory 13% Could not see or calculate total cost up front 12% Credit card was declined 10% Not enough payment methods 9% Baymard also reports that an ideal checkout can be completed with around 12-14 form elements, compared with an average of about 23 in the checkouts it has benchmarked, and estimates that better checkout design could lift conversion rates by about 35% for the average large ecommerce site. Every item on that list maps to something you can check before launch. 1. Products and catalogue # Check 1 Every product has a unique title, description, price, SKU and stock level 2 Variants (size, colour) work and show correct prices and images 3 Product images are high quality, compressed and have descriptive alt text 4 Categories and filters return correct results 5 Search finds products by name, SKU and common misspellings 6 Out-of-stock behaviour is defined (hide, show with notice, or back-in-stock alerts) 7 Sale prices, discounts and coupon codes calculate correctly 8 Product content is original, not copied from manufacturers 2. Cart and checkout # Check 9 Guest checkout is available 10 Shipping costs and taxes are visible before the final step

# Check 11 Checkout form asks only for essential fields; address autocomplete works 12 Mobile checkout is easy to complete with one thumb 13 Clear error messages appear next to the field that needs fixing 14 Order summary shows items, quantities, discounts, shipping, tax and total 15 Trust signals (secure payment badges, returns summary, contact options) are visible 16 Cart persists across sessions and devices for logged-in users 17 Abandoned-cart emails are set up and tested 3. Payments, tax and shipping # Check 18 Payment gateway is in live mode with correct credentials 19 Every payment method has been tested with a real transaction (cards, wallets, UPI, net banking or local options as relevant) 20 Refunds and partial refunds work from the admin 21 Failed and declined payments show helpful messages and allow retry 22 Tax rates are correct for every region you sell to 23 Shipping zones, rates, free-shipping thresholds and delivery estimates are correct 24 Cash on delivery rules (if offered) are configured and limited where needed 25 Invoices contain the legally required details Payment card security is governed by the PCI Data Security Standard. Hosted platforms and reputable gateways handle most of the burden, but confirm with your provider which responsibilities remain with you, and never store card details yourself. 4. Speed and mobile experience # Check 26 Home, category, product and checkout pages pass Core Web Vitals on mobile in lab tests 27 Largest Contentful Paint image is compressed, correctly sized and not lazy-loaded 28 Unused apps, plugins and scripts are removed 29 Images and embeds have set dimensions to prevent layout shift 30 Pages are tested on a mid-range Android phone and an iPhone

Speed is directly tied to revenue. Deloitte's Milliseconds Make Millions study found that a 0.1-second improvement in mobile site speed increased retail conversions by 8.4%. Google's thresholds are LCP within 2.5 seconds, INP within 200 milliseconds and CLS of 0.1 or less; our Core Web Vitals guide explains how to hit them. 5. SEO and AI search readiness # Check 31 Store is not blocked by robots.txt, password protection or noindex tags 32 Every page has a unique title tag and meta description 33 Clean URLs for products and categories; canonical tags set correctly 34 XML sitemap generated and submitted in Google Search Console and Bing Webmaster Tools 35 Product structured data includes name, image, price, currency and availability 36 Organization and breadcrumb structured data in place 37 Category pages have helpful introductory content 38 301 redirects mapped from any old site URLs 39 Internal links connect categories, products and buying guides 40 Google Merchant Center product feed set up if you plan to appear in Shopping results Google's documentation on Product structured data explains which properties enable rich results with price, availability and review information. Make sure the markup matches what shoppers see on the page. 6. Security and reliability # Check 41 HTTPS everywhere, with no mixed-content warnings 42 Admin accounts use strong passwords and two-factor authentication 43 Staff accounts have only the permissions they need 44 Automatic daily backups are running and a restore has been tested 45 Plugins, themes and platform are fully updated (for self-hosted stores) 46 Firewall and malware scanning enabled (for self-hosted stores) 47 Uptime monitoring and error alerts configured 48 Hosting can handle launch and sale-day traffic

7. Legal, policies and trust # Check 49 Privacy policy reflects what data you collect and why 50 Cookie consent configured where required 51 Terms and conditions, returns and refund policy, and shipping policy are published and linked in the footer and checkout 52 Contact details, business address and customer support hours are easy to find 53 Customer reviews or testimonials are genuine and displayed honestly If you collect personal data from customers in India, review your obligations under the Digital Personal Data Protection framework; other countries have their own consumer and privacy rules. 8. Analytics, emails and operations # Check 54 Analytics tracks product views, add-to-cart, checkout steps and purchases with revenue 55 Advertising pixels and conversion tags fire once per order, not on page reloads 56 Order confirmation, shipping and refund emails are branded and tested 57 Staff know how to process orders, refunds and returns 58 Inventory sync with warehouse, ERP or marketplaces is tested 59 Customer support channels (email, chat, WhatsApp) are staffed for launch 60 A rollback plan exists if something critical fails How should you run launch week? Soft launch first. Open the store to friends, staff or a small customer group for a few days and place real orders. Watch the funnel daily. Look at add-to-cart and checkout completion by device. A sudden drop at one step usually signals a bug. Check Search Console. Confirm the sitemap is processed, pages are being indexed and there are no crawl errors. Review site speed under real traffic and remove anything that slows key pages. Collect early feedback through post-purchase surveys and support conversations, and fix friction quickly. What should you do in the first 30 days after launch? Launch is the start of optimisation, not the end of the project. In the first month, focus on learning from real customers: 4. 5.

Week Focus What to look at 1 Stability Payment success rate, error logs, order emails, stock accuracy, support tickets 2 Funnel Drop-off between product view, add-to- cart, checkout start and purchase, by device 3 Search Indexing in Search Console, product rich results, early impressions and queries 4 Growth First A/B test on the biggest drop-off point, review requests to early customers, abandoned-cart email performance Keep a simple list of every issue customers report and how long it took to fix. Patterns in that list, such as confusion about delivery times or a payment method that keeps failing, are often the quickest wins available to a new store. It is also the right time to set up a maintenance routine: who applies updates, who checks backups, who reviews site speed each month, and how quickly urgent problems will be fixed. Stores that treat maintenance as an ongoing job stay fast and secure; stores that do not tend to slow down with every new app and campaign. Which platform makes launch easiest? Hosted platforms such as Shopify take care of hosting, security and much of the payment compliance, which removes several items from this list. Self-hosted WooCommerce gives more control but makes you responsible for updates, backups and security. Our Shopify vs WooCommerce guide compares the two in detail.
