How it compares
A launch means nothing against no one. These are the launches it is actually comparable to, and where this one sits among them.
| Compared with | Launches | Median views | This one | Rank |
|---|---|---|---|---|
| Product release the same kind of announcement | 954 | 692K | 4.6x | 136 |
| over 100K followers accounts of a similar size | 611 | 1.4M | 2.3x | 175 |
| Every launch all of them, for scale | 1981 | 688K | 4.6x | 289 |
What this launch shows
The post went out from an account with 164K followers. It was seen 19.2 times over. For over 100K followers the median reach is 2.4 times the following.
This launch beat that by 7.9 times. It ranks 175 of 611 launches from accounts that size. Against every launch in the directory it sits at 4.6 times the median of 688K views.
Saves led. 12K people bookmarked it, 38.5 per 10,000 views against a directory median of 11.7.
A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does. The rest: 741 replies, 752 quotes, 2K reposts.
It starts “Jev is now available to everyone”. It carries no media, which leaves the ranking model nothing to hold a reader with past the first line. The copy runs 13 words, shorter than a launch post here, where the median is 41.
There is a link in the body, which costs a post some reach and buys it a place to send people. It went out on a Sunday. Launches posted on a Sunday have a median of 526K views in the directory, and Friday is the strongest day at 880K.
The waitlist launch guide covers this: the call to action was a queue, and the four days after decide what the queue is worth. For the next one, read attributing signups to a launch: a save rate this high is the number to follow into the product.
Giving people something to reply to is the guide for it: the conversation is what carried this one. Every launch we track in Frontier Lab is on that vertical's directory page.
