Ask what they'll watch, page by page. A useful proposal names the templates and journeys: home, a top collection, a best-selling product, cart and the step into checkout. "We'll monitor your site" often means one homepage check every few minutes, which says little about whether people can buy.
Ask who gets each alert, and what they do next. Alerts sent to a shared inbox get ignored. Every alert should land with a named person, with a backup contact for nights and weekends and a first step written down.
Check they start with Shopify's own data. The web performance reports in your admin already show Core Web Vitals from real visitors. A specialist should read those before recommending paid tools. Extra tools can earn their place, but every monitoring script added to the storefront is also a script the store has to load.
Ask how they'll handle noise. A setup that alerts twenty times a week gets muted, and a muted alert is worse than none. Ask how they set thresholds and when they'll tune them after launch.
Ask for a sample weekly report. It should fit on one page: what alerted, what caused it, what changed in the store that week. Pages of charts without a conclusion are a red flag.
Know where monitoring stops. A monitoring specialist spots regressions and traces them to a cause. Fixing a slow template is speed work; fixing a broken app is troubleshooting. If you hire one specialist for both, price the watching and the fixing separately.
