I set up my blog a while back and resubmitted my site map to Google. Although it has indexed my blog page, it isn't indexing or crawling any of the 3 blog posts I have added so far. I know things with Google can take a while, so I left it a few weeks but still nothing. After Googling to see if anyone else has this problem I found this article where it acknowledges this is a problem and says that Wix Support have been of no help whatsoever: Blog Post Indexing Issue with WIX – Solved - StepForth Web Marketing Inc.
I tried adding a blog feed as the above article suggests. Still nothing.
Next I did a text. I left 2 blog posts alone and then in Google Search Console, manually submitted 1 of my blog posts. Bingo. This post about scare attractions.
