Just thought I’d jump in at this point.
It’s just been agreed with @james that I will start developing an SEO plugin for CP in the not too distant future. It will only have the basics to begin with and I can’t give any idea of timescales at present. It’s still very, very early days and in fact, I was going to hold off announcing this until I had some sort of plan in place.
Many of us (including me) have reservations about using Rank Math for a variety of reasons so far better to develop our own. Just to emphasise, this will be a plugin and not part of the core.
