RebelMouse has a structured data integration straight out of the box. This helps manage your structured data strategy with every article you publish. For example, in Entry Editor you will see a warning when a headline's word count goes over 110 characters. This is too long for Google's standards for structured data.
Please note that this is just a warning, and it will not prevent a user from publishing long headlines. If you have any questions about writing for structured data, contact email@example.com or your account manager today.
