A website maintenance contract keeps your site updated, secure and available. But “maintenance” covers very different services from one provider to another.

What it should include

  • Preventive: CMS, plugin, theme and PHP updates tested on staging; off-site backups with restore tests
  • Security: vulnerability monitoring, firewall, HTTPS, an incident procedure — see hacked website: the first 24 hours
  • Monitoring: uptime, performance, errors, forms
  • Corrective: fixes within defined response times
  • Evolutive: hours for small improvements

Clauses to check

Exact scope, response times by severity, included hours, reports, term and notice, and reversibility (access, code and backups handed back).

A good contract tells you what happens, and how fast, when the site goes down on a Friday night.

Prices: website maintenance cost. WordPress: monthly checklist.
