Trending feeds can be sorted by language, and with some plans, you can select to monitor a narrower time frame, including posts from the last 1, 3, 6, or 12 hours. 

If you would prefer to have trending content filtered based on total shares/shares by network (not how quickly it is being shared), select the option from the drop down above the feed dashboard.

Trending includes a geographic filter which lets you choose to see Trending Content from a specific country, or a state in the US.
