SEO plugin? Which one?

1

or this one

2

Never heard of the first one, and it’s quite old and not maintained.

I’d go for MetaKnight.

4

There is also Kirby SEO.

I think Meta Knight is not maintained anymore

5

I’d 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.

There’s also Kirby Meta by @fabianmichael: GitHub - fabianmichael/kirby-meta: All-in-one solution to all of your SEO/OpenGraph/JSON-LD needs. 👀
