What this launch shows

Inception posted this from an account with 244K followers and reached about 58.7% of them. The median for over 100K followers is 2.4 times, so this one stayed closer to home than most.

It ranks 553 of 611 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1501 of 1981.

Likes led, 1K at 91.6 per 10,000 views against a median of 26.8, with the heavier signals closer to usual: 544 bookmarks, 79 replies, 36 quotes. A like is a reaction. The post was enjoyed more than it was kept.

The first line is “Today we're excited to announce Mercury 2.5”, a first-person opening that the founder-account launches in the directory use most. It carries a 43-second video against a directory median of 65 seconds. Videos between 30 and 90 seconds have a median of 603K views in the directory.

The copy runs 39 words, about the usual length for 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 Tuesday. Launches posted on a Tuesday have a median of 651K views in the directory, and Friday is the strongest day at 880K.

Attributing signups to a launch covers this: a save rate this high is the number to follow into the product. For the next one, read giving people something to reply to: the conversation is what carried this one.

Why posts from large accounts under-reach is the guide for it: a post seen by fewer people than follow the account was held back by the ranking model. Every launch we track in Frontier Lab is on that vertical's directory page.
