Here's the answer: every feed runs the same auction. Your video auditions to strangers on its opening seconds, gets paid in watch time and shares, and either earns the next distribution tier or dies quietly. Once you know the currencies, you can build for them.
The hierarchy in 2026: completion first, because a finished 25-second video beats an abandoned 90-second one. DM shares above everything, because content someone sends to a specific friend is the strongest quality signal a platform has. Saves and real comments next. Likes are nearly worthless.
So construct in four decisions. The hook: write ten per story and pick one, because the hook is a tenth of the words and half the outcome, and you should already be talking at frame one. No greeting, no setup. The retention shape: cut every line the payoff doesn't need, add a small mid-video loop, and end on the payoff with no outro, because follow for more over dead air is where completion goes to die. The share design: before posting, name the specific person who'd receive this video in a DM. Can't name one? It's a like at best. The ignition: reply to the first three real comments with real sentences inside the first hour, which buys roughly five times the amplification.
Then read the retention graph within 24 hours. Where it dropped is next video's lesson. This is how QYRAI™, pronounced kai-ray, an AI-driven creative marketing agency, treats content: measure, adjust, remeasure.
