Product Development Checklist for E-Commerce

Calculate landed cost, COGS, pick-pack, shipping, marketplace fees, and return rate. Set CAC and CPA guardrails so every test aligns with contribution margin and payback targets.

Use Google Trends, Keyword Planner, and Amazon category volume to confirm seasonality and intent. Prioritize SKUs where search volume, margins, and supplier lead times line up.

Spin up a feature-light PDP, drive small-budget traffic from Meta and TikTok, and measure CTR, ATC, and checkout start. Collect emails or preorders to prove intent before inventory commitments.

Scrape top PDPs and Amazon reviews to find repeated complaints on sizing, shipping speed, or quality. Turn pain points into headline copy, FAQs, and imagery that directly address objections.

For cosmetics, supplements, or electronics, review FTC, FDA, CE, and CPSIA requirements. Avoid restricted phrasing and ensure required warnings and documentation are present on PDPs and packaging.

Align ads, content, and influencer activations to supplier lead times and inbound freight buffers. Add contingency for QC failures so campaigns do not drive demand you can't ship.

Issue unique SKUs and GS1 GTINs for each variant so inventory, feeds, and returns stay accurate. This is essential for Google Shopping, marketplaces, and warehouse scanning.

Use 3-5 high-res images plus a short video and 360 where useful. Serve WebP/AVIF via a CDN, include scale references, and show size on-model to cut fit-related returns.

Add JSON-LD Product schema with price, availability, and aggregateRating. Ensure canonical URLs per variant to prevent duplicate content and stabilize organic rankings.

A/B test title length, price presentation, trust badges, and "Ships by" messaging using VWO or Optimizely. Optimize for add-to-cart rate and scroll depth on mobile.

Automate review requests via post-purchase flows and showcase UGC that answers sizing and material questions. Moderate for shipping-specific complaints and update PDP copy accordingly.

Create complementary bundles and volume discounts tied to margin thresholds. Use in-cart cross-sells that do not slow checkout and validate lift with A/B testing.

Offer Apple Pay, Google Pay, PayPal, and local wallets to cut form friction. Track conversion by payment method and prioritize those that lift mobile checkout completion.

Use Avalara or TaxJar for nexus tracking, EU VAT OSS, and category-specific codes. Display estimated tax early to prevent surprises that spike cart abandonment.

Enable AVS/CVV checks, 3D Secure on risky markets, and risk scoring via Stripe Radar or Kount. Monitor chargeback rates and fine-tune rules to avoid blocking good orders.

Trigger email and SMS within 30 minutes with dynamic cart contents and a soft incentive. Cap discounts to protect margin and stop sending once purchase is detected.

Offer free shipping above a calculated AOV where shipping cost as a percent of revenue stays profitable. Show delivery estimates pre-checkout to reduce anxiety.

For replenishable items, add subscription cadence options with clear incentives and easy pause features. Use dunning and card updater tools to curb involuntary churn.

Evaluate cut-off times, same-day pick-pack, and zone coverage. Connect via ShipStation or native apps and test label costs and error rates before migrating fully.

Blend historical sales, campaign calendars, and lead times to project demand. Set safety stock and reorder points per SKU to avoid stockouts during paid pushes.

Allow customers to exchange sizes and generate RMAs without tickets. Automate restocking and refunds and measure return reasons to feed back into PDP improvements.

Right-size mailers vs boxes to cut dimensional weight fees while protecting goods. Add QR inserts for care instructions and UGC prompts to reinforce retention.

Assign HS codes, estimate duties, and consider DDP with tools like Easyship. Localize size charts and translate key PDP content for top international locales.

Inspect incoming lots using AQL and document defects to prevent costly returns. Share defect photos with suppliers and adjust POs to maintain quality standards.

Implement GA4 ecommerce events (view_item, add_to_cart, begin_checkout, purchase) with value and currency. Use server-side tagging and ensure Meta and TikTok pixels receive deduped events.

Pipe orders into a warehouse like BigQuery and compute LTV by acquisition source. Set CAC caps based on gross margin and return rates, not top-of-funnel CPMs.

Deploy welcome, post-purchase care, replenishment, and winback sequences in Klaviyo or similar. Segment by product type and RFM to keep incentives profitable.

Use behavioral data to surface recently viewed and complementary items via Nosto, Algolia, or custom logic. Track impact on AOV and repeat purchase rate.

Defer non-critical scripts, lazy-load below-the-fold media, and use an image CDN. Monitor LCP, CLS, and INP via Lighthouse and real-user monitoring to protect SEO and conversion.

Create macros in Gorgias or Zendesk for "Where is my order", sizing exchanges, and address changes. Publish clear policies and track CSAT and first response time.
