A Monthly Website Maintenance Checklist

Website problems rarely arrive without warning. Most of them build up slowly: an update skipped here, a broken link there, a backup job that quietly stopped running three months ago. A short monthly routine catches these issues while they are still small.

This checklist is designed for business owners and marketing managers who want a repeatable process. For a typical small business site it takes an hour or two once you are familiar with it. Work through it in order, note anything that needs follow-up, and keep a simple log of what you checked and when.

Before you start

Have these to hand so you are not hunting for logins halfway through:

• Admin access to your content management system.
• Access to your hosting control panel and domain registrar.
• Google Search Console and your analytics account, which for most sites is now GA4.
• A spreadsheet or document to use as your maintenance log.

1. Backups

1. Confirm that automatic backups have run on schedule throughout the month.
2. Check that at least one recent copy is stored somewhere other than your web server.
3. Take a fresh manual backup before you make any updates.
4. Every few months, test a restore on a staging site. A backup you have never restored is a hope, not a plan.

2. Software updates

1. List the available updates for your core platform, themes and plugins or extensions.
2. Read the notes for major updates, particularly anything flagged as a security fix.
3. Apply updates on a staging copy first if you have one, then on the live site.
4. After updating, click through the key pages and test the main functions.
5. Remove plugins and themes you no longer use. Inactive software can still carry vulnerabilities.

3. Security checks

• Review the list of admin users and remove anyone who no longer needs access.
• Check that two-factor authentication is switched on for admin accounts where available.
• Look at your security plugin or hosting security reports for failed logins or flagged files.
• Open the Security issues and Manual actions reports in Google Search Console to confirm nothing is listed.
• Confirm your SSL certificate is valid and not close to expiry.

4. Forms, checkout and key journeys

Broken forms are one of the most expensive silent failures on a business website, because nobody complains about an enquiry they could not send. Each month:

• Submit every contact and quote form and confirm the email arrives in the right inbox.
• Check any automatic replies still read correctly.
• If you sell online, run a test order through checkout and confirm the payment and confirmation emails work.
• Test click-to-call links and any booking tools on a mobile phone.

5. Speed and performance

1. Run your homepage and two or three important pages through PageSpeed Insights.
2. Check the Core Web Vitals report in Search Console. The thresholds for a good rating are LCP of 2.5 seconds or less, INP of 200 milliseconds or less and CLS of 0.1 or less.
3. Look for new, uncompressed images added during the month, which are a common cause of slower pages.
4. Note any pages that have got noticeably slower since last month and investigate the cause.

6. Content accuracy

• Check contact details, opening hours, prices and team pages are still correct.
• Remove or update expired offers, past events and out-of-date announcements.
• Make sure the copyright year and any legal pages, such as privacy and cookie policies, are current.
• Scan recent blog posts or news items for typos and missing images.

7. Links and errors

• Run a broken link check with a crawler or plugin and fix or redirect anything returning an error.
• In Search Console, open the Pages report and look for new pages that are not indexed or that return errors.
• If you moved or deleted pages this month, confirm that 301 redirects are in place.

8. Search and analytics health

• Compare clicks and impressions in the Search Console Performance report with the previous month, allowing for seasonality.
• Check that your analytics is still recording data. Tracking often breaks silently after a site change.
• Confirm your XML sitemap is submitted and shows a successful status.

9. Hosting, domain and email

• Check upcoming renewal dates for your domain, hosting and any paid plugins.
• Look at disk space and resource usage in your hosting panel.
• If you send email from your domain, confirm SPF, DKIM and DMARC records are still in place, especially if you have changed email providers.

10. Record and report

Finish by writing a short summary in your maintenance log: what was updated, what was fixed, what still needs attention and who is responsible. Over time this log becomes very useful. It helps you spot patterns, gives a new team member or supplier a clear history, and shows exactly what changed if something goes wrong.

Quarterly extras

Some tasks do not need doing every month but should not be forgotten. Once a quarter, consider:

• Testing a full backup restore.
• Reviewing all user accounts across hosting, domain, analytics and Search Console.
• Checking your site on a range of devices and browsers.
• Reviewing your most visited pages to see whether the content still reflects your business.

Key takeaways

• A monthly routine catches small problems before they turn into outages, lost leads or security incidents.
• Always back up before updating, and test that backups can be restored.
• Test forms and key journeys by hand, because they fail silently.
• Keep a log. It turns maintenance from a chore into a record you can rely on.
