Website monitoring: what should you actually monitor?

A practical guide to monitoring availability, forms, customer journeys and the technical signals behind them.

Start with business outcomes

List the actions that generate leads or revenue and rank them by impact. For most stores that means checkout. For service businesses it is usually a contact or booking path.

Monitor the critical pages

Monitor the pages customers must reach, but do not stop there. A page being reachable is only useful if its controls, forms and next steps still work.

Test forms and conversion paths

Use a real browser for journeys that depend on JavaScript, widgets or multi-step interaction. Passive checks are safer for anonymous scans; active tests belong on verified sites.

Use technical signals as context

JavaScript errors, failed network requests and server responses are valuable because they help explain a broken journey. They should support the business-impact signal rather than replace it.

A practical monitoring rule

If the failure would cost a lead, booking or order, monitor the complete customer action rather than only the page or server behind it.
