Website monitoring checklist for agencies

Agencies juggle many client sites. This checklist covers what to monitor, how to route alerts, and how to communicate status without drowning in noise.

Prioritize client-facing URLs

Start with homepages, checkout, booking, and APIs each client relies on. Tag monitors by client or project for filtering.

Add SSL and domain coverage

Track certificate and registration expiry per hostname. Client stacks often mix registrars, CDNs, and managed WordPress hosts.

Separate internal and client alerts

Engineering may need webhooks; account leads may need email. Avoid sending every client all technical noise.

Document incident communication

Decide who contacts the client, what status page or message template you use, and when to escalate beyond a single monitor.

Use status pages where they help

For SaaS or high-visibility clients, a read-only status page can reduce repeated “is it down?” messages during incidents.

Review coverage quarterly

Onboard new launches, retire old domains, and confirm alert contacts still match the team handling each account.

Practical monitoring guide

Example content below is illustrative — values are placeholders, not live customer data.

Client onboarding checklist

  • Collect production URLs, API paths and stakeholder contacts in one brief.
  • Tag monitors by client for filtering, reporting and handoffs.
  • Add SSL and domain expiry for every public hostname you support.
  • Agree who receives alerts on the agency vs client side before go-live.

What to monitor first

  • Homepage and primary conversion or login path.
  • Checkout, booking or lead-capture endpoints tied to revenue.
  • Certificate and domain dates before the next client billing cycle.

Alert routing checklist

  • Route to the pod that owns the contract, not a shared agency inbox only.
  • Include a backup contact for nights, weekends and client timezone gaps.
  • Test alert delivery during onboarding — not after the first real outage.

Status and client communication

  • Define what you will tell the client for degraded vs full downtime.
  • Link a status page or update channel the client can share with their users.
  • Log incident start, updates and resolution for QBR and renewal conversations.

Frequently asked questions

What should agencies monitor first?

Client homepages, critical landing pages, SSL certificates, domains, and APIs tied to revenue or lead flow.

Can one workspace cover many clients?

Yes. Use tags and naming so filters, reports, and status pages can scope monitors per client or product.

Do clients need their own status page?

Depends on service importance. Critical SaaS and high-traffic sites benefit most; simple brochures may need alerts only.

How does SitePuls help agencies?

Uptime, API, SSL, domain, and heartbeat monitors share alert contacts and incident history in one workspace.
