Website Maintenance: The Monthly Checklist for a Fast, Secure Site

An unmaintained website degrades quietly: outdated plugins, forms that stop delivering, slower pages, broken links. The problem is rarely visible straight away, but it costs you clients. Here is our monthly checklist.

Security and backups

  • Check that automatic backups run and that a restore has actually been tested.
  • Update the CMS, theme and plugins after checking them on a staging environment.
  • Remove unused plugins and user accounts.
  • Check the HTTPS certificate and its expiry date.

Performance

  • Measure Core Web Vitals: Google considers an experience good when LCP is under 2.5 s, INP under 200 ms and CLS under 0.1.
  • Compress new images and use modern formats such as WebP.
  • Check that recently added third-party scripts aren't slowing the site down.

SEO

  • Review Google Search Console: indexing errors, excluded pages, queries going up or down.
  • Fix broken links and add the redirects you need.
  • Check that the sitemap is up to date and new pages are indexed.

Conversion and forms

  • Send a test message through every form and check it arrives (email, CRM).
  • Test the key journeys: contact, booking, checkout.
  • Check conversion tracking in your analytics tools.

Content

  • Update details that change: prices, opening hours, team, offers.
  • Review your most visited pages and improve those that convert poorly.
  • Publish or refresh at least one useful piece of content for your clients.

Do it yourself or delegate?

This checklist takes a few hours a month and some technical skills. If your team is short on time, our managed services handle it, with a monthly report. Read also when to outsource website maintenance.

Frequently asked questions

How often should a WordPress site be updated?

Security updates should be applied quickly. For everything else, a monthly pass tested on staging is good practice.

How long does monthly maintenance take?

For a brochure site, a few hours a month is usually enough. An e-commerce or feature-rich site needs more testing.

What happens if a website isn't maintained?

The risk of security breaches grows, the site slows down, features stop working and Google visibility can drop.
