All-in-one SEO
An all-in-one SEO plugin is the one I use, it is installed by default on Hostinger web hosting.
This plugin provides basic guidance and helps to create more optimized content for Search engines.
At this moment I cannot recommend other plugins since the feedback they are getting at the moment isn’t complimentary.
I have used in the past Yoast SEO, Rank Math, and SEOPress and didn’t have any troubles with them.
