Website maintenance is the regular work that keeps a website secure, working, fast and up to date. A neglected site slowly breaks: forms stop sending, plugins become vulnerable, information goes stale and pages slow down. Most of these problems are invisible until a customer finds them.

What maintenance covers

Area	Tasks
Software updates	Updating the platform, theme and plugins, especially security updates
Backups	Automatic backups stored separately, and a tested restore
Security	Strong unique passwords, two-step login, removing unused accounts and plugins
Functionality	Testing forms, booking, checkout and links
Speed	Checking load times and image sizes
Content	Updating prices, opening hours, team, services and dates
Search	Checking Search Console for errors and pages losing visibility
Renewals	Domain name, hosting and security certificate renewals

Security comes first

The National Cyber Security Centre's guidance for small businesses stresses keeping software up to date, backing up data and using strong passwords with two-step verification. For websites, outdated plugins and themes on platforms such as WordPress are a common way in for attackers. Apply updates promptly, remove anything you no longer use, and limit who has admin access.

Keeping the site fast

Slow pages lose visitors, especially on mobile data. Check key pages with PageSpeed Insights every few months and after changes. The usual culprits are oversized images, too many plugins or scripts, and cheap hosting under strain. Resize and compress images before uploading, and question every new plugin.

Checklist

Weekly (or automated)

Backups run successfully
Security and plugin updates applied
Contact form and booking tested

Monthly

Check Search Console for errors and drops
Review opening hours, prices and offers
Remove spam comments or form entries
Check for broken links on key pages

Quarterly

Run PageSpeed Insights on main pages
Review user accounts and remove old ones
Test restoring a backup
Update team, services and portfolio pages

Yearly

Check domain and hosting renewal dates and contact details
Review the privacy notice and cookie set-up
Read through every page as a new customer would

Do it yourself or pay for a support plan?

On hosted website builders, much of the technical maintenance, such as software updates and security, is handled by the provider; you look after content and checks. Self-hosted sites, such as most WordPress sites, need someone to manage updates and backups. Many web designers offer monthly support plans. Before signing, ask:

Which tasks are included, and how often?
How quickly will they respond if the site goes down?
Where are backups stored, and how often are restores tested?
How many hours of content changes are included?
Will you keep admin access and ownership?

Questions

What is website maintenance?

Regular work to keep a website secure, working, fast and current: updates, backups, security checks, testing, content updates and renewals.

How often should a website be maintained?

Some tasks weekly or automatically (backups, updates), others monthly, quarterly and yearly, as in the checklist above.

Do website builders need maintenance?

Less technical maintenance, as the provider updates the platform, but you still need to keep content, forms and settings current.
