Does anyone know how I can find out the usage stats for Product Mentions? I cannot find them in the admin section.
Unfortunately there is no analytics available for the product mentions feature as yet.
I would encourage you to add your vote and comments to this idea exchange post - http://community.lithium.com/t5/Product-Ideas/Analytics-needed-for-the-product-mentions-feature/idi-...
I do think it is very important to be able to test the feature's effectiveness, and tweak accordingly.
