or this one
Never heard of the first one, and itโs quite old and not maintained.
Iโd go for MetaKnight.
There is also Kirby SEO.
I think Meta Knight is not maintained anymore
Iโd advise to not go for Meta Knight as it has been unmaintained for a while, with quite a few breaking bugs in the open, and the agency has made no notice of trying to maintain or update Meta Knight.
Thereโs also Kirby Meta by @fabianmichael: GitHub - fabianmichael/kirby-meta: All-in-one solution to all of your SEO/OpenGraph/JSON-LD needs. ๐
