And I also just store extra keywords in the database and output them only inside meta tags in the head section. They stay hidden on the page but still help search engines.

wanted to add that you can store extra SEO keywords in the database and output them inside a meta tag, like meta name="keywords". They won’t show on the page, but search engines can still read them. Another option is a hidden textarea in the admin panel that only gets rendered in the head section. Curious if anyone here has tried something similar with packages like Spatie SEO?
