Website Maintenance Checklist: What to Review Every Month

A website can look fine while a form stops sending, a plugin falls behind, a phone number becomes outdated, or an important page disappears from search. A short monthly review catches those problems before customers do.

Use this website maintenance checklist as a repeatable operating routine. Record the date, result, and owner for each item instead of relying on memory.

1. Test the customer journey

Open the site on a phone and a computer, then complete the most important actions as if you were a customer.

• Submit every contact, quote, booking, and newsletter form.
• Confirm the success message appears.
• Confirm the notification reaches the correct inbox or system.
• Test phone, email, map, checkout, and scheduling links.
• Check the main call to action from the home page through completion.

Do not use a real charge to test checkout unless you have an approved test mode or a clearly reversible process.

2. Check business information

Review hours, phone numbers, email addresses, locations, pricing language, staff details, policies, and current offers. Compare important details with your Google Business Profile and other public listings.

Remove expired announcements. An old holiday banner or unavailable service creates doubt even when the rest of the site is current.

3. Review updates and security

For a managed platform or content management system, review core, theme, plugin, and dependency updates. Read the release notes and back up the site before applying changes that could affect production.

Also check:

• Administrator accounts and access levels
• Multi-factor authentication where available
• Security or hosting alerts
• Domain and certificate expiration dates
• Unexpected new users, files, redirects, or pages

Updates should follow the platform’s tested deployment process. A maintenance checklist is not permission to make an unreviewed production change.

4. Confirm backups can be restored

A green “backup completed” message is useful, but restoration is the real goal. Confirm the latest backup date, storage location, retention period, and the documented restore procedure.

Periodically test restoration in a safe staging environment. Do not wait for an outage to learn that the backup is incomplete.

5. Check speed and mobile usability

Open the highest-traffic pages on a real phone connection. Look for oversized images, layout shifts, slow third-party scripts, unreadable text, and buttons that are difficult to tap.

Use a performance tool to track changes over time, but pair the score with an actual visit. A fast page that hides the call to action is still not doing its job.

6. Find broken links and missing pages

Crawl the site or review the most important pages manually. Fix broken internal links, missing images, redirect chains, and links to outdated external resources.

Confirm the site’s sitemap loads and includes the public pages you want search engines to discover. Check that important pages have one clear canonical URL.

7. Review search and analytics signals

Compare the month with the previous period:

• Organic search clicks and impressions
• Top landing pages
• Form completions or other meaningful conversions
• Sudden traffic or ranking drops
• New indexing, mobile, or security warnings

Use the data to choose one or two focused improvements. Do not rewrite every page because of a normal short-term fluctuation.

8. Record what changed

Keep a simple maintenance log with the date, person responsible, checks performed, changes made, proof, and anything deferred. This makes the next review faster and helps identify recurring failures.

If the same problem returns, improve the process rather than repeating a manual fix forever.

A 30-minute monthly version

If time is limited, prioritize this sequence:

1. Test forms and primary calls to action.
2. Confirm backups and security alerts.
3. Check business information and expired offers.
4. Review the top five landing pages on mobile.
5. Check Search Console and analytics for major changes.
6. Record the result and owner of any follow-up.

A monthly website maintenance checklist will not prevent every incident, but it makes silent failures much less likely and gives the business a clear record of what was verified.
