Here's the myth: you launch a website, and then you have a website. Done. It just sits there, working, until you need to change something.
That's not how it works. WordPress sites run on a stack of moving parts — core software, plugins, themes, a server underneath all of it, a certificate proving to browsers you're legitimate. Every one of those parts updates on its own schedule, sometimes conflicts with something else when it does, and occasionally breaks something you rely on. Nobody sends you an email when that happens. You find out when a customer mentions it, or when a competitor asks if you knew your site was down.
The specific things that bite people: a plugin update that fights with another plugin and kills the contact form — not with an error message, just silently stops delivering emails. An SSL certificate that expired because nobody was watching it, and now every visitor gets a "Not Secure" warning before they even see your homepage. Spam bots that find an unprotected form and flood it until you can't find the real inquiries. A WordPress core update that went wrong because nobody checked for compatibility first. None of these are exotic problems. They happen to real local businesses every week.
And the cost of finding out too late is real. Every day your contact form doesn't work is a day a potential customer filled it out and heard nothing back — and hired someone else. Every week your site throws a security warning is a week Google is watching and quietly updating its opinion of you. A 404 page where your services page used to be doesn't just disappoint visitors — it tells search engines your site is unreliable. These aren't technical problems. They're business problems.
