Welcome to the Q&A Forum

As a recent Moz subscriber, I'm trying to up my game in terms of inbound marketing.  One of the most pressing tasks is to add json-ld across all of my WordPress sites. What is the best way to do this? Should I use the technique set out here: https://moz.com/blog/using-google-tag-manager-to-dynamically-generate-schema-org-json-ld-tags Or should I use one of these plugins? https://en-gb.wordpress.org/plugins/schema/ https://en-gb.wordpress.org/plugins/wp-structuring-markup/ I want to get this right so any guidance would be gratefully received.
