CHECK IF GOOGLE CAN INDEX YOUR CONTENT WITH A SITE: SEARCH

Summary from the TLDR Marketing newsletter

To check whether Google can index specific content on a page, copy a snippet of text and search site:[URL] [snippet of text] in Google. Check whether the text appears in the result's meta description. If it does, Google can access that content. If no results appear, test a few other snippets to confirm there may be an indexing issue.
