Hello,
Thank you for contacting Rank Math today.
Could you give us more details about why is it not being indexed? Did you get any error in the Search Console?
Just by checking the links I think it could be due to Thin Content, since Google recommends at least 300 words of unique content. You can read more about it here: https://www.searchenginejournal.com/what-is-thin-content-how-to-fix-it/270583/
Looking forward to helping you. Thank you.
Thanks for the reply
When looking at the Google Search Console I get the following indicating it has not been indexed.

Hi,
As per this website, your pages are indexable:

Please note that in your screenshot, the last check date is 11 May. Maybe you had that issue before switching to Rank Math. You must allow Google some time to check your website again.
Hope that helps.
