Quick answer
Website maintenance is the routine work that keeps a live website secure, fast, accurate and online. It covers software updates, backups, security checks, uptime and speed monitoring, link and content checks, and a yearly review of what the site is meant to achieve. Most of it follows a rhythm: a few quick checks every week, a bigger pass every month, a deeper review every quarter and a full audit once a year.
This checklist shows what to do at each interval, and which jobs you can handle yourself and which are worth handing to a specialist. Every site is different, so maintenance is quoted per website. Contact us for a quote based on your platform, your features and how much your site matters to your business.
Why websites need maintenance after launch
A website is software, and software ages. Plugins, themes and platforms release updates, security certificates expire, links break and content drifts out of date. None of this happens all at once, which is why neglected sites often look fine until the day something fails.
The security side is measurable. Patchstack’s State of WordPress Security in 2026 report counted 11,334 new vulnerabilities in the WordPress ecosystem in 2025, a 42% increase on 2024, and 91% of them were in plugins rather than in WordPress itself. It also found that about half of high-impact vulnerabilities were exploited within 24 hours. Other platforms have their own risks, but the lesson carries over: fixes arrive in updates, and attackers move quickly against sites that have not applied them. Our non-technical guide to zero-day exploits explains why speed matters.
Maintenance also protects what a website is for: speed, search visibility and customer trust. A slow or broken site loses enquiries long before anyone notices a technical fault.
What website maintenance includes
| Area | What it covers | What goes wrong without it |
|---|---|---|
| Updates | Platform core, plugins, themes and libraries | Known security holes stay open, and features break when one update is skipped |
| Backups | Database and files, kept in more than one place, with restores tested | One failed update or attack means rebuilding from scratch |
| Security | User accounts, strong passwords, two-step login, malware scans, a firewall | Stolen logins, spam injections and defaced pages |
| Monitoring | Uptime, speed, errors and form delivery | You learn the site is down from a customer |
| Renewals | Domain, hosting, SSL certificate and plugin licences | Browser warnings or a lapsed domain |
| Content and links | Accuracy of pages, broken links, outdated offers | Visitors hit dead ends and wrong information |
| SEO and analytics | Search Console errors, tracking and indexing | Pages drop out of search and nobody notices |
| Features | Forms, checkout, booking and integrations | Leads and orders fail silently |
The website maintenance checklist
Use these intervals as a starting rhythm and adjust them to your site. A shop with daily orders needs closer attention than a five-page brochure site.
Every week
- Open the site on a phone and a computer, and check the homepage, a key service page and the contact page.
- Submit a test enquiry through each form and confirm it arrives in the right inbox.
- Check that the latest backup completed.
- Review security alerts and failed login attempts.
- Clear spam from comments and form submissions.
Every month
- Back up first, then apply updates to the platform, plugins and themes, and test the site afterwards. WordPress’s own guidance is to back up before updating, check that plugins and themes are compatible, and visit the site afterwards to confirm everything works.
- Review user accounts. Remove people who no longer need access and turn on two-step login for administrators.
- Check speed and Core Web Vitals. The targets are loading the main content within 2.5 seconds (LCP), responding to interactions within 200 milliseconds (INP) and keeping layout shift to 0.1 or less (CLS), measured at the 75th percentile of visits. Our Core Web Vitals guide explains each one.
- Scan for broken links and 404 errors, and fix or redirect them.
- Open Google Search Console and look for indexing or crawl errors.
Every quarter
- Practise a restore. Confirm you can bring the site back from a backup, ideally on a test copy. A backup you have never restored is an assumption, not a plan.
- Review content: opening hours, services, team details, offers, dates and contact information.
- Remove plugins, themes and tools you no longer use. Each one is extra code to keep updated.
- Test the main business journey end to end on mobile: buying, booking or requesting a quote.
- Check third-party scripts such as chat widgets and tracking tags, and confirm you still need them.
- Spot-check accessibility: keyboard navigation, readable colour contrast and image descriptions on key pages.
Every year
- Check renewal dates for your domain, hosting, SSL certificate and paid plugins, and make sure the contact email on each account is one you read.
- Run a full security review: administrator accounts, permissions, your hosting plan, old files and forgotten test pages.
- Review your privacy policy and cookie consent set-up. What applies depends on where your visitors are, for example GDPR for visitors in Europe and state privacy laws in the US.
- Compare the site with your business goals. If your services, audience or branding have changed, plan what to update, and read what affects the cost of a website before you scope bigger changes.
After a big change or an incident
- After a redesign, migration, new plugin or hosting change, repeat the weekly checks and look in Search Console for new errors.
- After a security incident, change every password and key, restore from a clean backup, and find out how access was gained before the site goes live again.
Who should look after your website?
There is no single right answer. Choose by how much the site matters to your income and how comfortable you are with updates and backups.
| Option | Works well when | Watch out for |
|---|---|---|
| Do it yourself | The site is small and simple, and you are comfortable in the dashboard | Missed updates, nobody to call when something breaks, and the time it takes |
| Freelancer | You want one named person for updates and fixes | Cover when they are unavailable, and who holds the logins |
| Agency or maintenance plan | The site drives revenue or has custom features, and you want monitoring and a response process | What is included, how fast urgent issues are handled, and how reporting works |

What a website maintenance plan should include
Plans differ widely, so compare what is included rather than what the plan is called. Ask for these in writing:
- Which updates are covered (platform, plugins, themes) and how often
- Whether updates are tested on a copy before they go live
- How often backups run, where they are stored and whether restores are tested
- Monitoring for downtime, security problems and speed
- How quickly urgent problems are handled, and who to contact
- Regular reports on what was done
- What is billed separately, such as content changes, design work or new features
- Who owns the domain, hosting and accounts, and how handover works if you leave
Maintenance is quoted per website, because the platform, plugins, features, traffic and level of support all differ. Contact us with your website address and a short description of what the site does, and we will put together a quote.
Warning signs your website needs attention
- Browsers show a not secure or certificate warning
- Pages load slowly or time out at busy times
- Update notices have been waiting for weeks or months
- Contact form emails stop arriving
- Unexpected redirects, strange pages or odd titles appear in Google results
- Nobody can say when the last backup was tested
- The site relies on a plugin or theme that is no longer supported
Frequently asked questions
What is website maintenance?
Website maintenance is the ongoing work that keeps a site secure, fast, accurate and online after launch. It includes updates, backups, security checks, monitoring, content and link checks, and renewals for the domain, hosting and certificates.
How often should a website be maintained?
Quick checks weekly, updates and security reviews monthly, content and restore tests quarterly, and a full audit yearly. Security updates for important software should not wait for the next monthly pass if they are urgent.
How much does website maintenance cost?
There is no single answer, because maintenance depends on your platform, plugins, features, traffic, how much support you want and how quickly problems must be fixed. We quote each site individually. Contact us with your website address and what it needs, and we will send you a quote.
Do I need maintenance if my site is on Wix or Squarespace?
Hosted builders usually handle core software updates and hosting security for you, but you still look after content, apps and integrations, forms, domain renewals, accessibility and search checks. A lighter version of the weekly and monthly checks still applies.
Can I maintain my own website?
Yes, if the site is simple and you are comfortable with updates and backups. Use the checklist above, keep a record of every login, and know who to call when something breaks. Consider a specialist when the site takes payments, collects personal data or relies on many plugins.
What happens if I never update my website?
Security holes stay open, plugins and themes can stop working with newer software, speed and search visibility decline, and a failure is harder to repair because the gap between your version and the current one has grown.
