Blog Page not being indexed?

Hi,
I;m not convinced my blog page is being indexed.
https://www.nusparkmarketing.com/blog-3/

My regular page is
https://www.nusparkmarketing.com

I’m not a programmer or much of a techie,
But I’ve tried to submit site maps, robot files, etc.

I’d like someone to go thru the specific steps or contact me and we’ll do a desktop share with my wordpress dashboard, webmaster tools, plugins whatever.

Thank you.
Paul
