.@with_sherpa turns more website visitors into customers by running experiments autonomously. Ryan used Sherpa to ship 40 website experiments in 30 days and lifted Lindy's conversion 30%. So they made a movie about it. Congrats on the launch @ethan_kinnan and @norbusonam!

What this launch shows

The post went out from an account with 1.6M followers and was seen by fewer people than follow the account. The median for over 100K followers is 2.4 times, so this one stayed closer to home than most.

It ranks 598 of 611 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1824 of 1981.

Replies led. 17 of them, 7.9 per 10,000 views against a median of 2.3.

The post started a conversation, and the ranking model pays for conversation with reach in the hours after. Bookmarks came in at 63, reposts at 13.

The first line is “.@with_sherpa turns more website visitors into customers by running experiments autonomously”. It carries a 1:13 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 42 words, about the usual length for a launch post here, where the median is 41. The body carries a link, so the post had somewhere to send the reader and paid a little reach for it.

It went out on a Monday. Launches posted on a Monday have a median of 618K 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.
