My idea is to grant users the ability to set-up "structured data" on blog posts to help with SEO.
Structured data is a system of pairing a name with a value that helps search engines categorize and index your content. Microdata is one form of structured data that works with HTML5. Schema.org is a project that provides a particular set of agreed-upon definitions for microdata tags.
Structured data seems to matter more often now with search engines and help boost SEO.
A little bit of a delayed update here, but just wanted to note you can now easily add custom HTML into the <head> section of individual blog posts. This makes it possible to add structured markup, such as JSON-LD schema, for each post. Click here to learn more.
Any questions/comments/concerns, please let us know.
Our engineering teams are actively working on making it easier to add structure markup to HubSpot-hosted blogs posts. We are starting with adding the ability to specify JSON-LD in the blog post <head> section (see this idea for more information).
As soon as we have an update available, I'll be sure to update this post.
