What is a Twitter cap? How should I decide what to set my cap as?

What is a Twitter cap?

A Twitter Cap is a user-set limitation on how many tweets Compass will capture and analyze in a 24-hour period.

Compass allows you to view all or a sample of tweets related to your seed and the keywords that the software identifies as the most closely related to your seed term. This is dependent on the volume of tweets and your Twitter budget. A good lower bound for a vibrant conversation is at least 10,000 messages a day.

How do I decide what to set my Twitter cap as?

This is primarily dependent on your Twitter budget and how vibrant the conversation is surrounding your seed.  A simple rule of thumb is to determine approximately how many tweets per day your chosen seed(s) is/are generating, and then set your Twitter cap at about 1.15x that amount.  See the article on "Smart Listening" for more information.

​Is there a maximum daily Twitter cap?

Technically there is no upper bound on the number of Tweets collected daily, as long as you stay within the limits of the Compass usage agreement. Most conversations are well captured by a daily cap between 20,000 - 100,000.

However, you should consider whether you need to listen to all tweets related to your seed(s), or if listening to a statistically significant portion will be representative enough for your needs. For most use-cases, it is not necessary to listen to all tweets/messages.
