A promoted trend features in the Trending Topics on the Left of Twitter Dashboard.

Another way to spot the promoted trend is that irrespective of the position it stands after the promotion, it’s the only, which has the number of tweets mentioned besides it.
You need at least a Lakh of Rupees to trend a topic for a couple of hours.
