Hi Peter,
Thanks for you reply. I have added the MB RankMath plugin and the key and value to the fields. This works fine for the meta title and description.
What I am doing is adding shortcodes into the default text editor which are inserting the location and service from the MB custom fields. At the moment RankMath cannot analise these. Is there a way to get RankMath to analise them? I am also using the DIVI page builder to throw that into the mix.
Here is a screenshot showing where I have added the shortcodes: https://indigomarmoset.agency/dev/mbtest/mb.png
Thanks,
