The website maintenance checklist (monthly and yearly)

A website is not a one-time purchase. Use this monthly and yearly checklist to keep yours secure, fast, accurate and ready for customers.

By Zentorum Agency5 min readUpdated 1 Nov 2026

A website is a bit like a shop. You would not open the doors on day one and then never sweep the floor, restock the shelves or check the lock. Your site needs the same small, regular care.

The good news: most of it takes minutes. This checklist breaks the work into monthly, quarterly and yearly jobs so it stays manageable.

Why maintenance matters

  • Security. Out-of-date software is a common way for sites to be attacked.
  • Speed. Sites tend to slow down as files and plugins pile up. See why is my website slow.
  • Trust. Wrong prices, old hours or broken forms make customers doubt you.
  • Visibility. Search engines prefer sites that work and stay current, although nobody can guarantee any ranking.
  • Lower cost. Small fixes are cheaper than emergency repairs.

Monthly checklist

Set a calendar reminder for the same day each month. Aim for about an hour.

1. Open your site like a customer

Visit your homepage and main pages on your phone and on a computer. Look for anything broken, odd or out of date.

2. Test the contact form and key buttons

Send a test message. Make sure it arrives, and that the automatic confirmation works. Click the phone number and the booking or buy buttons. A broken form can cost you customers for weeks without you noticing.

3. Check the speed

Load the page on mobile data. If it feels slower than before, investigate new large images or added tools.

4. Install updates

If your site runs on a system such as WordPress or a store platform, update the core software, themes and plugins. Update one at a time and check the site after each. Skip this and you leave doors open.

5. Check backups

A backup is a saved copy of your site. Make sure one ran recently and can be restored. A backup you have never tested is only a hope.

6. Look for broken links

Click through menus and the main links in your pages. Links to pages that no longer exist frustrate visitors.

7. Review messages and spam

Clear out spam from forms and comments. Answer real enquiries quickly.

8. Look at your numbers

Check your visitor statistics: how many people came, which pages they visited, and where they came from. You are looking for changes, not perfection.

Quarterly checklist

Every three months, go a little deeper.

  1. Review your content. Are the prices, services, hours and team photos still right?
  2. Refresh your top pages. Update examples, add new work, and remove anything that is no longer true.
  3. Check your Google listing. Make sure it matches your website. See how to set up a Google Business Profile.
  4. Review user accounts. Remove access for former staff or freelancers and use strong, unique passwords.
  5. Test on different devices. Try another browser and another phone.
  6. Check images. Compress any new large ones.
  7. Read your reviews and respond. They often point to problems on your site too.

Yearly checklist

Once a year, treat it like a service for your car.

Renew what expires

  • Domain name: make sure the registration is current and auto-renew is on. Our guide on choosing a domain name explains how domains work.
  • Hosting: check the plan still suits your traffic and price.
  • Security certificate (the padlock): usually renews automatically, but confirm it.
  • Paid tools and plugins: cancel those you do not use.

Take a fresh look at the design

Does your site still reflect your business? Compare it with your competitors. Has your offer changed? Does the homepage still say what matters? A homepage that sells gives you a useful checklist.

Review the basics

  • Is your main call to action still the best one?
  • Do you need new pages or a clearer path to buy?
  • Is the site still easy on phones? See mobile first.
  • Do you need a legal update, such as privacy or terms?

Check ownership and access

Know where your domain is registered, who can log in, and where backups are kept. Keep the logins in a safe password manager, not in an old email. You should own the files and accounts for your own site.

Security basics for every site

  • Use long, unique passwords and a password manager.
  • Turn on two-step login wherever it is offered.
  • Give each person their own login, with only the access they need.
  • Remove old plugins and themes you do not use.
  • Keep your own computer and phone up to date.

What to do if something breaks

  1. Stay calm and note exactly what you see and when.
  2. Check whether anything changed recently, such as an update.
  3. Restore the last good backup if needed.
  4. Contact your developer or host with the details.
  5. Test everything again before you relax.

Keep a simple site log

Open a shared note or spreadsheet and record each job as you finish it: the date, what you did, and anything odd you saw. After a few months, the log shows patterns, such as a plugin that keeps causing trouble or a page that always has broken links.

It also helps if you hand the site to someone else. A new developer can see at a glance what has been done and what is due. Include the renewal dates for your domain, hosting and paid tools, and the name of the person responsible for each one.

DIY or hand it over?

You can do the monthly checks yourself. For updates, backups, security and fixes, many owners prefer to hand it over so they can focus on customers. Either way, put the dates in your calendar today.

Printable summary

  • Monthly: look, test forms, speed check, updates, backup, links, spam, numbers.
  • Quarterly: content, Google listing, access, devices, images, reviews.
  • Yearly: domain, hosting, certificate, tools, design review, ownership.

Quick questions

How much time does website maintenance take?

For a small site, a monthly check can take under an hour if you follow a list. Updates, backups and fixes take longer if you have put them off.

Do I need maintenance if my site is simple?

Yes, though less. Even simple sites need working forms, renewed domains and correct information.

What happens if I never update my website?

Over time, old software can become a security risk, links can break, pages can slow down and information can go out of date. All of these cost you trust and customers.
