the best schema plugin available

no other words to say than this ones: SNIP is the best! Let me say that I’ve tried ALL the schema plugin in their Pro version, and when I say ALL I mean ALL (the last one I tested is the superb schema module in rankmath pro, but SNIP is even better). You can create every possible schema and customize them in all their properties (which are “mapped” on schema.org so you have a searchable field and you can import them with all the supported properties). The plugin has a free video course and a lot of other resources you’ll need to use the plugin at its best). The customer service is pure gold.
