WordPress maintenance checklist
Good WordPress maintenance is about regularity: updates, backups, security, performance and monitoring done structurally rather than only when something breaks. The core of a maintenance checklist is: update the core, theme and plugins safely, create and test backups, keep security in order, scan for malware, watch speed and uptime, and review users, permissions and forms. Below is a complete, practical checklist with a short note on why each item matters.
Core, theme and plugin updates
Outdated software is by far the most common cause of hacked WordPress sites. Update the WordPress core, the active theme and all plugins regularly — preferably on a staging environment first, so you can test updates before they go live. Read the changelog for major updates, as they can bring changes or conflicts. Remove plugins and themes you do not use: every extra plugin is a potential attack surface and extra maintenance.
Backups and restore tests
A backup you have never restored is not a backup but an assumption. Set up automatic backups of both files and database, store them off-site (separate from the web server) and keep multiple versions. The crucial and most forgotten part: periodically test that you can actually restore a backup. That way you know you can get back online quickly after an outage, a bad update or a hack — instead of discovering that recovery fails at the very moment you need it most.
Security and hardening
Limit access and the attack surface. Use strong, unique passwords with two-factor authentication, limit login attempts and protect or hide the login page. Put a web application firewall in front of the site, keep SSL/HTTPS active and correctly configured, and run a supported PHP version. Check file permissions and disable editing theme and plugin code from the dashboard. Much of this overlaps with secure hosting, where firewall and server security are already handled at platform level.
Performance and speed
A slow site costs you visitors, conversions and search rankings. Keep caching active and correctly configured, optimise and compress images (and use modern formats), clean the database regularly (revisions, transients, spam), and limit the number and weight of plugins. Periodically check load time with a tool like PageSpeed Insights and keep an eye on Core Web Vitals. Performance maintenance is not a one-off: new content and updates can slowly degrade speed.
Malware scanning and uptime monitoring
Scan the site regularly for malware and for unwanted file changes, so you catch an infection before visitors or Google do. Combine this with uptime monitoring that alerts you the moment the site is unreachable or slows down. Together they form your early-warning system: the sooner you spot a problem, the smaller the damage and the faster the recovery. If the site does get infected, follow our step-by-step guide WordPress hacked: what now?
WooCommerce, users, permissions and forms
If you run a web shop, treat WooCommerce with extra care: test the order and payment flow after every update, keep payment and shipping plugins current, and watch the PCI and privacy aspects of customer data. Also review users and permissions: remove old accounts, give no one more rights than they need, and check for unknown administrators. Finally, test your forms (contact, quote, newsletter): do emails arrive, does storage work, and do you meet GDPR for the data collected? If you want to hand all this over, see WordPress maintenance or the broader website maintenance.
Frequently asked questions
Short, direct answers to the most common questions.
A complete checklist includes: updates for core, theme and plugins (preferably on staging first), automatic and tested backups, security and hardening (strong passwords, 2FA, firewall, SSL), performance optimisation, regular malware scans, uptime monitoring, WooCommerce checks for a web shop, user and permission management, and testing of forms. Each item reduces the chance of downtime, hacks or data loss.
Install security updates as soon as possible, ideally within a few days of release. Routine updates, a malware scan and a backup check belong at least monthly, and weekly for busy or business-critical sites. Uptime monitoring runs continuously. A thorough review of performance, users and forms can be done quarterly. Regularity matters more than the exact frequency.
Because outdated core, themes or plugins are the most common way in. Updates close known security holes that attackers actively exploit, often shortly after a flaw becomes public. Besides security, updates also bring bug fixes, compatibility with new PHP versions and new features. Test major updates on staging first to avoid surprises on the live site.
Yes, your own backups remain wise. Host backups can be limited in retention, frequency or accessibility, and often sit on the same platform — a risk during a server failure. So keep your own off-site backups, with multiple versions, and periodically test that you can actually restore them. Two independent backup routes give the most certainty.
Yes, and for most businesses that is the sensible choice. With outsourced maintenance, updates are tested and applied, backups monitored and tested, security watched and problems solved proactively — without you spending time on it or missing risks. The site stays secure, fast and up to date, and you can focus on your own work.
Without maintenance, risks pile up: unpatched flaws make a hack more likely, missing or untested backups make recovery uncertain, and the site grows slower and more error-prone as plugins and PHP age. In the worst case the site goes down, you lose data or customer records, and your visibility and reputation suffer. Maintenance is cheaper than recovery.
