Design is just as important as content. Design in terms of how nice the site looks and design in terms of ux and usability. If people ignore your site because it looks cheap then the content is pointless. Most users really expect SPAs, they don't expect having to reload the entire site to see new content.

Then you get into usability and many react component libraries really work well with you there. Accessibility for the visually impaired is baked into the library and the popular libraries follow modern UI conventions.
