Introduction
A website does not become maintenance-free after launch.
Forms can stop delivering email, third-party integrations can expire, software can become outdated and business information can slowly become inaccurate.
Monthly maintenance does not mean rebuilding the site every four weeks. It means checking the parts that could quietly affect customers or revenue.
This checklist works for many business websites regardless of the platform.
1. Confirm Backups Are Running
Do not assume a backup system is working simply because it was configured months ago.
Check that recent backups exist, include the required website data and are stored somewhere recoverable.
For business-critical websites, periodically test the restoration process.
A backup that cannot be restored is not a useful backup.
2. Test Contact and Lead Forms
Submit every important form as a real visitor.
Confirm that the success message appears, notification email arrives and any CRM or spreadsheet integration receives the lead.
Email delivery can fail after DNS, hosting or mail-provider changes.
Lead forms should be treated as business infrastructure, not decorative page elements.
3. Check Important User Journeys
Test the actions customers use most often.
This may include booking, checkout, account login, downloads, quote requests or WhatsApp links.
Do not only inspect the homepage.
A problem on the final conversion step can exist while the rest of the website looks normal.
4. Review Software and Dependencies
CMS websites, frameworks, plugins and external libraries receive updates over time.
Review available updates and apply them using an appropriate testing process.
Do not update everything blindly on a complex production site without a recovery point.
Remove dependencies that are no longer used.
5. Check Security Alerts and Accounts
Review administrator accounts and remove access for people who no longer need it.
Check security or hosting alerts for suspicious activity.
Use strong unique passwords and multi-factor authentication for critical accounts where available.
Website security includes hosting, domain, email and third-party services, not only the CMS login.
6. Review Performance
Websites often become slower gradually as new images, scripts and features are added.
Check important templates and investigate noticeable regressions.
Look for oversized media, extra marketing tags or new widgets that load across every page.
Performance maintenance is easier when problems are caught early.
7. Check Broken Links and Missing Media
External resources disappear and internal URLs change.
Review important pages for broken links, missing images and outdated downloads.
Automated crawling tools can help on larger sites, but manual review of key commercial pages is still valuable.
Fix redirected internal links so the site points directly to current destinations.
8. Update Business Information
Check service descriptions, team members, pricing guidance, contact details, hours and policy information.
Outdated content creates customer confusion even when the website is technically healthy.
Remove expired campaigns and old offers.
Keep the site aligned with how the business actually operates.
9. Review Analytics and Search Data
Look for unusual drops in traffic, conversions or indexed pages.
Check whether key forms and events are still being recorded.
Search Console can reveal indexing or performance issues that are not visible from the front end.
Use trends to decide whether deeper investigation is needed.
10. Document What Changed
Keep a simple maintenance log.
Record major updates, plugin changes, hosting changes, incidents and significant content edits.
Documentation helps the next developer understand what happened when a problem appears.
It also prevents teams from repeating the same troubleshooting work.
