Early bird
Discounted registration that closes on a published date. The discount is the visible half and the deadline is the working half, because a deadline moves people who have already half decided to come. Early bird does a second job as a signal: the size of the early-bird take tells you whether an audience exists at all, months before the room has to fill. Its close is also an announcement moment, and the convention is to pair it with the program launch so the two spikes land together. A free event has no price to discount, so the mechanic gets read one level up. Build a real deadline instead: a first batch of spots that closes, a seat guarantee or a perk for anyone registered by a date, a small session only early registrants get into. Faking a sold-out is not the free-event version of this, it is just a lie your community can screenshot.
Source: Standard registration practice, documented most concretely in the DevOpsDays organizing guide, which advises offering discounted early-bird registration to encourage people to register early, schedules the early-bird close at T-3.5 months alongside the program launch so that people who bought before there was a program are rewarded, and gives the reading number: “Did we sell a good bit of early bird tickets? What to look for is probably 15% of the expected ticket sales (e.g., of 400, 60 early birds). Again, this shows an audience and interest.” That share is a structural anchor for reading your own pace, not a target to copy. Samaaro’s promotion timeline places the early-bird deadline in the ramp phase for the same urgency reason.
