Website Maintenance Checklist: Monthly, Quarterly and Yearly Tasks

A website is not a one-time project. Software ages, security threats change, content goes out of date and small problems quietly accumulate. Regular maintenance keeps your site fast, secure and effective, and it costs far less than repairing a hacked or broken site. Use this checklist to stay on top of it.

Weekly tasks

• Confirm the site is online and key pages load correctly.
• Check that automatic backups completed successfully.
• Submit a test enquiry through your main contact form.
• Review new enquiries, comments and form spam.
• Apply urgent security updates if any were released.

Monthly tasks

• Update the CMS, plugins, themes or framework dependencies, after a backup.
• Run a security scan and review login activity for unusual attempts.
• Test checkout and M-Pesa payments if you sell online.
• Check Google Search Console for new errors and pages that dropped out of the index.
• Review analytics: traffic, enquiries and top pages compared with last month.
• Fix broken links and missing images.
• Remove unused plugins, accounts and test pages.

Quarterly tasks

• Restore test: restore a backup to a test environment to confirm it actually works.
• Speed review: test key pages with PageSpeed Insights and fix regressions.
• Content review: update prices, services, team members, opening hours and contact details.
• SEO review: titles, descriptions, internal links and structured data on key pages.
• Accessibility check: readable contrast, alt text and keyboard navigation.
• User accounts: remove access for former staff and contractors.

Yearly tasks

• Renew your domain name and check the registration details are in your business's name.
• Confirm the SSL certificate renews automatically.
• Review hosting performance and capacity against your traffic.
• Update your privacy policy and terms if your data practices changed.
• Review your site structure and plan improvements or a redesign if needed.
• Check that brand assets, photos and messaging still reflect your business.

Why are tested backups so important?

A backup you have never restored is a hope, not a plan. Keep automatic daily backups stored separately from your hosting, retain several versions and test a restore regularly. When something goes wrong, a working backup turns a disaster into an inconvenience. See also data backup and disaster recovery.

What happens if you skip maintenance?

Skipped task	Typical consequence
Software updates	Known vulnerabilities exploited by automated attacks
Backups	Data lost permanently after a failure or hack
Form testing	Enquiries silently lost for weeks
Domain renewal	Website and email go offline
Content reviews	Customers see old prices, staff or services
SEO monitoring	Ranking drops noticed too late

Should you maintain the site yourself or use a plan?

If you have technical skills and time, you can follow this checklist yourself. Most businesses prefer a maintenance plan, because tasks are done consistently, updates are tested before they reach the live site and someone is responsible when something breaks. Compare the cost of a plan with the cost of a single day of lost enquiries or a hack clean-up. Read why maintenance plans save money.

Who should have access to your website?

Keep a list of everyone with access to the website admin, hosting, domain and analytics, and review it every quarter. Give each person their own account rather than sharing logins, grant only the access they need, and remove accounts as soon as staff or contractors leave. Shared and forgotten accounts are among the easiest ways for attackers to get in, and among the easiest risks to remove.

How should maintenance be documented?

Keep a simple log of what was updated, when, and by whom, along with the location of backups and a list of who has access to the site, hosting and domain. Good records make troubleshooting faster and handovers between providers painless.

Example: what a monthly check catches

During a routine monthly check, a maintenance team notices that a plugin update has stopped the quote form sending notifications, while the form still shows a success message to visitors. Enquiries were being saved but nobody was alerted. Because the check runs monthly, the issue is caught within days, the notification is fixed and the stored enquiries are followed up, instead of weeks of silent lost leads.
