Structured Markup to Indicate Flexible Sampling / Metering

Hi there,

We are looking at using this plugin, but does it add the required markup so Google knows we are using metering, ie. 3 article per day, etc. as Google recommends?

We need to ensure our SEO will not be negatively affected.

Thanks for your help and guidance.
