Advice on WIX for a small local business SEO

Hi,

I am currently using Wix for one of my client's local massage therapy website. I've been looking everywhere most people say that Wix is horrible for SEO. I have worked with wordpress with good SEO results using Yoast. However, I just wanted some opinions on WIX. My clients wix website is just a simple modern design with just information and a book now / call now ATC. Since its a local business I will only be doing simple SEO but mostly doing media buying on google ads.
