I am using plugin-The SEO Framework for SEO optimization. Unfortunately, it does not add Schema.org microdata as JSON-LD script in site posts. I want to use a hook to add a code for outputting Schema.org microdata as a JSON-LD script for articles. Could you please tell me the code. I do not want to use plugins for micro-markup, so as not to create unnecessary load.
GeneratePress adds basic structured data by default. However, extending it would require quite of bit of custom development.
If it were me and I need a more robust structured data system, I would 100% find a plugin to do it. The extra load you get from a good plugin will be very close to the extra load you get from having something custom coded.
we see a lot of mixed reviews for different schema plugins. Might be best to ask on our FB group as we have a lot of users that will have more experience of the different plugins available:
