Is One page (or single page) website design Good or bad for SEO?

According to me, the single-page website isn't preferable compared to multiple pages with proper categories.

Single page websites are bad for SEO. Or at the very least they aren't optimal for search optimization. This doesn't necessarily mean that they're bad for selling or making money, but a single-page website is not going to do well in Google search results for a number of reasons.
