A website isn't a brochure you print once — it's software running on the internet, and software needs upkeep. Here's a realistic cadence, not a paranoid one.
Weekly: automated backups (so a bad update is always reversible), and a quick uptime check if you don't have monitoring in place.
Monthly: CMS and plugin updates, a broken-link check, and a look at analytics to see what's actually changing in traffic and behaviour.
Quarterly: a security review, a performance check (page speed tends to creep up as content and plugins accumulate), and a content refresh on your most important pages.
Yearly: a genuine look at whether the design, messaging and structure still reflect where your business is now — not where it was when the site launched.
Skipping this doesn't usually cause a dramatic failure — it causes a slow decline: a slightly slower site, a plugin conflict nobody noticed, rankings quietly slipping. Our Website AMC plans exist to keep this cadence running without it being one more thing on your own plate.
