When looking at what the Google bots can view when crawling the page, it appears they cant see any of the text. I believe this is due to the use of Flash instead of HTML on XTheme.
X doesn’t use flash anywhere. Your WordPress setup might be blocking search engines. In Settings > Reading, ensure Search Engine Visibility is unchecked.
X is SEO ready however, you will need a plugin like Yoast SEO to display information for search engines. This is not an issue with X or themes in general. You might want to contact our trusted partners who caters X setup and customization needs. Please see https://community.theme.co/custom-development/
