A website is less like a printed brochure and more like a car: it runs on software that ages, on servers that need watching, in an environment that gets more hostile every year. A care plan is the service schedule - here is what a legitimate one includes, so you can judge what you are paying for.
Software and security updates applied promptly (the number one hack vector is outdated components). Daily off-site backups - tested ones. Uptime monitoring that alerts a human. SSL renewal. Speed checks. And a monthly allowance of small changes - prices, photos, text - so the site stays current instead of slowly fossilising.
Ask any provider: 'When my site goes down on Saturday night, what happens?' A real care plan has an answer with names and hours in it. 'We would probably notice Monday' is what no-plan looks like - and it is how sites stay hacked for weeks, quietly serving spam under your brand.
Compare it to one incident: a hacked site means emergency cleanup, lost rankings, blacklist warnings and days offline - easily twenty times a year of care fees. Ours start at £15/month and include the small-changes allowance most owners actually use every month. Details on the plans page.
