Let me tag along on this thread and voice my opinion on why such a feature would be of utmost importance for the HubSpot team.
As a Marketing guy, I would love to use HubSpot for the all-in-one tool for all things marketing. Being able to integrate Bing while also having Google would make me spend the additional license fee to have it both work from within HubSpot.
I think many others are on the same page as I am. Numerous features that aren’t available in HubSpot make it an okay tool, but with a few tweaks, HubSpot could take over the marketing world by storm.
Integrating Bing would be one of these things. It’s a must.
