A website maintenance plan is a written schedule for keeping a site secure, accurate, recoverable, and usable. It should name the systems covered, the person responsible, the check frequency, the evidence to retain, and the response when something fails. A calendar reminder alone is not a plan; every task needs a clear owner and a verifiable result.

Start with the systems that can break

Inventory the domain registration, DNS, hosting, content management system, themes or packages, forms, payment or booking integrations, analytics, email delivery, certificates, backups, and administrator accounts. Record where each system is managed and who controls the account. Keep passwords and recovery codes in an appropriate credential manager rather than in the maintenance document.

Prioritize work by consequence. An expired domain, failed checkout, lost form submission, missing backup, or vulnerable dependency deserves a faster response than a minor copy edit. The NIST patch-management guide describes patching as preventive maintenance that reduces the chance of compromise, data breach, and operational disruption.

Use a repeatable cadence

A practical weekly check can cover uptime, important forms, checkout or booking paths, visible errors, security alerts, and pending updates. Monthly work can include dependency review, broken-link checks, accessibility spot checks, performance trends, account access, and a review of business details such as hours and contact information. Quarterly work can test restoration, review vendor ownership and renewal dates, remove obsolete access, and confirm that privacy and retention statements still match the site.

Backups need their own acceptance test. NIST's patch-management security practices include backing up data, exercising restoration, and being prepared to recover data used by critical software. A successful backup job therefore is not the same as a demonstrated restore. Choose a representative recovery exercise, record the restored item and time, and keep the result without exposing private data.

Record evidence and exceptions

For each task, note the date, exact asset or account checked, before-state when a change is risky, action taken, direct verification, and unresolved exception. Separate verified facts from vendor notices and untested assumptions. If a change fails, use the documented rollback path and record whether service returned to the prior state.

The plan is working when routine checks finish on schedule, critical renewals have an accountable owner, updates do not bypass testing, and a restore can be demonstrated. Review the plan after any outage, provider change, major release, or ownership transfer so that the document continues to describe the real website rather than an earlier version of it.
