Arguably, if the website does not have a positive value and only negative, the logical thing is to shut it down and keep the Google Business profile imo. I assume she has been paying for the domain name all this years too or is it a subdomain?
I think the new version is a net positive value as creates a better "vibe" to prospective patients than just a Google Business listing would, and I expect will age well.
The domain's used for email anyway and is on a very cheap local hosting plan, probably all-in-all like ZAR 84 per month and ZAR 200 per year for the domain, so ZAR ~1200 (USD ~75) per year.
Old website was built in a different era, Google Business didn't exist, "HTML5" wouldn't be a thing for another 5 years, web design styles were completely different and was before iPhone meaning that modern day "mobile friendly" was not even a thought.
When my father started running guest suites over 10 years-ago I made a single page website with essentially the same goals but using a Hugo template. The website still feels "modern" today, so I expect this new one of my mother's will age well too.
Scope of work and urgency were so minimal that it was simply not worth the hassle to actually subscribe and then have to unsubscribe later.
If there was no free option we could have done it on my Claude sub or she would have just paid.
