Go to your community, list your discussions in the last month by the number of views, and look at the top questions listed there.
Take the top 5 to 10 and send them to an internal expert to write a detailed answer or opinion piece on one of them.
Then promote the piece internally and externally. If you have some paid social budget, you can use this to promote the answer too.
There aren’t many wins as easy as taking some of the most popular questions in your community and inviting a product or topic expert to create a world class solution for your members.
