Periscope Question

I run a few Periscope accounts for my businesses and I'm trying to figure out why at certain times broadcasts are wayyyy more crowded than others. One of the accounts I run is @camwithher and we have models sign on and broadcast to promote our site. We've built up the account fairly nicely (28K following) and usually get around 100 to 300 users in chat on every broadcast. BUT every once in a while the numbers spike to over 1K and I have no clue why that is. It doesn't seem like anything is different or the broadcast is shared more than other times so I'm trying to figure out what the outlier is here.

Hey, thanks for sharing. I dont know the exact answer to your question. But i think sometimes the broadcast can be featured in the search section longer than other times.... then that would send a lot of viewers to the broadcast and sometimes less. I think the caption is very important as well. Message me on skype: sm.mkt - I own 5 periscopes with similar theme and we range from 10k-80k followers per account.
