Website Maintenance Checklist: What to Do Weekly, Monthly and Yearly

A website is not finished on launch day. Without regular care it slowly becomes slower, less secure and less accurate, and the day it breaks is always the busiest day of the year. This website maintenance checklist splits the work by schedule so nothing depends on memory.

Daily (automated)

• Backups: files and database, stored somewhere other than the same server.
• Uptime monitoring: an alert by email or messenger when the site stops responding.
• Security monitoring: alerts for failed logins and changed files.

None of these should need a person. Set them up once and check that the alerts actually reach someone.

Weekly

• Submit your own contact form and place a test order. Forms and payment gateways fail silently more often than anything else.
• Review new enquiries and orders to confirm none were missed.
• Check the error log for repeated errors.
• Publish or update content if you have a content plan.

Monthly

• Update the core system, theme and plugins or libraries, on a staging copy first where possible.
• Check speed on the main templates; new content and plugins often slow things down.
• Scan for broken links and fix or redirect them.
• Review Search Console: coverage errors, manual actions and pages losing traffic.
• Review analytics: traffic sources, conversion rate and top pages against last month.
• Remove unused plugins, old user accounts and test pages.

Quarterly

• Restore a backup to a test environment. A backup that has never been restored is only a hope.
• Review access: who has admin rights, and do they still need them? Rotate important passwords.
• Content audit: update prices, team members, opening hours and outdated articles.
• Test on current devices and browsers.

Yearly

• Renew the domain and SSL certificate, and confirm the registration email still works.
• Review hosting: is the plan still right for your traffic?
• Check legal pages and privacy notices.
• Run a full SEO and accessibility audit.
• Decide whether the design and structure still fit the business; see the signs your website needs a redesign.

What usually goes wrong without maintenance

1. An outdated plugin is exploited and the site is flagged as dangerous.
2. The domain expires because renewal notices went to an old email address.
3. The contact form stops sending and nobody notices for weeks.
4. Backups exist but cannot be restored.
5. The site gets slower with every added feature until rankings and sales fall.

Every item on this list is cheaper to prevent than to repair.

In-house or outsourced?

A person on your team can handle content, form tests and reviewing reports. Updates, security and backup restores need technical skill. Many businesses combine the two: an internal owner for content and a maintenance contract for the technical side. A good contract states response times, what is included each month and how work outside the scope is priced.

A simple way to keep the checklist alive

Put each item in a shared calendar with an owner. Keep a short log of what was done and when. When something breaks, the log is the fastest route to the cause.

Summary

Use this website maintenance checklist as a calendar, not a document: automate the daily tasks, test forms weekly, update and measure monthly, restore a backup quarterly and renew and audit yearly. For sites built on a custom codebase, maintenance is lighter because there are fewer third-party parts to update; see what custom software is.

FAQ

How much maintenance does a small site need? An hour or two a month is usually enough if backups and monitoring are automated.

Is it safe to enable automatic updates? For security patches, generally yes. For major versions, test on a copy first.

What is the single most important task? A tested, off-site backup. It turns every other disaster into an inconvenience.
