This thread is about using Smart Content the main website, not on LP’s. I am not sure where you got that a Pro customer isn’t using LP’s.
Smart Content would be SUPER useful on the main website as well.
I keep coming up with ideas for my Shopify client. I have another client on WP that is using smart content on landing pages, but it would be much better to deliver the smart content to the main website as well. Actually, if we had this option, I wouldn’t have to use the one landing page. Since the content would be on the main site, it would be pretty much seamless, which would also be a better user experience.
The OP was well before HS announced their move to a stand-alone CMS. Nonetheless, I raised this questions during Partner Day in May and was directed to the product manager of Smart Content. We had a good conversation about this and was told they are circling around to this feature now to fully develop it out. While HubSpot knew how they liked to use Smart Content internally, they never grasped exactly how their customers would.
I am not expecting Smart Content to be available on 3rd party sites. But I am hopeful that it will eventually because it has awesome potential. Otherwise, HubSpot’s is hand-cuffing some customers that can’t ever be on their CMS.
