There are four steps between the notification and a conversation, and people fall away at each one. Knowing where is more useful than changing images at random.
Step one: the notification
Lost here are people with notifications off and people who swiped it away without looking. Little to influence, except timing: a story posted at four in the morning is not the first thing in a morning notification sweep.
Step two: opening it
Almost everyone who sees it opens it. Being named by someone works. Also lost here are people whose privacy settings hid the story — the notification arrived, the content did not.
Step three: reading the caption
The narrowest point. You have a few seconds and one sentence. What works is specifics: what you offer and to whom. What does not work is anything that looks like the opening of a long text.
More on writing that sentence: what to put in a story caption.
Step four: the reply
Replying to a story is easier than starting a chat from scratch — the reply box is already there. Use that: ask for a word back rather than a click. A link sends the person somewhere they are alone again; a reply brings them to you.
What happens next
The reply lands as an ordinary message. From then on it is a conversation with a conversation's rules — and speed decides: why fast replies matter.
How Neurogram does this
Everything above is manual work that runs into the number of hours in a day. Neurogram does it on your own accounts and without you: it collects channels and audiences, writes comments and replies with a language model, and keeps limits and quiet hours so the accounts survive.
