What this launch shows

The post went out from an account with 12K followers. It was seen 2245.2 times over. For 5K to 25K followers the median reach is 50.8 times the following.

This launch beat that by 44.2 times. It ranks 1 of 479 launches from accounts that size. Against every launch in the directory it sits at 38.1 times the median of 688K views.

Every response ran below the directory's usual rate: 80 bookmarks, 14 replies, 4 quotes and 25 reposts against 362 likes.

The post was seen more than it was acted on, which is common for a launch that reaches past the people who care about the category. One bookmark for every 4.5 likes is a low ratio for a launch, and reads as entertainment more than intent.

It starts “Series E - raising $950 million from new and existing investors, led by @Tiger_Global and @GVteam, at a…”. It carries no media, which leaves the ranking model nothing to hold a reader with past the first line.

The copy runs 45 words, about the usual length for a launch post here, where the median is 41. 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.

How to announce a funding round covers this: the round is the news and the post has to turn it into customers and hires.

For the next one, read whether a launch needs a video: 99% of the launches in the directory carry one, and the guide is about when the 1% is the right call. Virality without conversion is the guide for it: reach that outruns response is the pattern this guide is about.
