I’m using ACF extensively on my website, but it seems like Google doesn’t see the content? Website testing tools show a couple of words per page, even though I have lots of ACF fields filled with content. Am I missing something, or is ACF not good for SEO?
Not having seen your site, I couldn’t say, however, when content that you can clearly see is not being indexed my experience is that it’s usually some type of HTML tag nesting issue causing the crawler’s XML parser to choke.
Have you tried running your page through some kind of HTML validation?
