Measure Largest Contentful Paint, Cumulative Layout Shift, and interaction delays using realistic devices, throttled networks, and cached states. Track regressions by page type, prioritize fixes that lift conversion, and validate CDNs, image formats, and lazy loading. Tie numbers to meaningful business impacts, not abstract technical vanity.
Continuously simulate add‑to‑cart, address entry, shipping selections, taxes, discounts, and payment authorization across gateways and currencies. Capture screenshots, network logs, and errors automatically, then route failures to the right owners. Prove resilience under peaks with staggered schedules and safe synthetic orders that never pollute reports.
Validate product availability, variant logic, images, pricing, and structured data against your source of truth. Catch broken links, orphaned categories, and stale copy before shoppers do. Monitor search synonyms, merchandising rules, and recommendations so seasonal changes uplift discovery rather than introducing embarrassing surprises or silent dead ends.
Identify your money paths: search to PDP, PDP to cart, cart to checkout. Document systems, owners, and risks. Define acceptable thresholds for vitals and errors. Pick two markets and devices. Align stakeholders on goals, cadence, and evidence format before building anything automated or permanent.
Create reusable journeys with parameters for locale, currency, inventory, and gateway. Add screenshots, logs, and data validations. Set schedules tied to deployments and morning checks. Publish a shared dashboard and agree on alert destinations, severity definitions, and response expectations everyone understands and willingly supports.
Stress test edge cases, calibrate thresholds, and fix noisy steps. Run a show‑and‑tell with merchandisers, support, finance, and engineering. Invite subscribers to alerts and a weekly digest. Ask for one improvement request from each group, then deliver it quickly to build lasting momentum.
