Ilana's JSON‑LD for SEO (TM)

This app is awesome but the support and info are even better. Opt in for the daily email and you will get tons of information everyday in your email. You cant go wrong with this at all unless you hate great info and improving your data structure on your site. This is a no brainer, especially at a one and done price! Started seeing rich snippets just as advertised and emails are always answered quickly.
