How much historical data can I see in Social Tracker?

Social Tracker can gather Engagement and Posting data from the previous 60 days (28 days for YouTube) or up to 2000 posts (1000 for YouTube) starting from the day you add a profile to your campaign. Audience data is available only from the day that you add social profiles to the tracker.

So if you created a new Social Tracker campaign on August 31st of 2018, you would be able to see data from July 1st, 2018.
