SEO without yoast

I’m transferring a blog to frontity for a client
for SEO I installed the head tags plugin and package, but the client said me he doesn’t use yoast (or any SEO plugin)
so I imagine that without this he should have everything manually in the frontity project, and that will over complicated things
so is there another easy solution, or should I advise him to use yoast as it make things easier and automatic for everybody

Hello Alexandra!

How is he managing the head tags right now? In his “classic WordPress” installation I mean

Using the Head Tags plugin is the equivalent of doing wp_head in a PHP theme. It gets all the default WordPress tags, even if no SEO plugin is installed.
