Hook

The hook is the first thing a person sees or hears when they come across your content: the sentence on a carousel's cover, the words on screen in a video's first seconds, the opening line of a caption. Its only job is to stop the thumb. On Instagram and TikTok nobody's searching for your content: they stumble onto it while scrolling. If in that instant you don't give them a reason to slow down, everything else — the nice photos, the polished copy, the offer — never gets seen.

The reason the hook matters so much is practical, not philosophical. Platforms show content to a small group of people first and watch how they react. If almost everyone scrolls past immediately, the content stops circulating. If many stop, save, or move to the next slide, it keeps getting shown. So the hook is the front door: it doesn't decide a post's fate on its own, but without a good one the content never even reaches the point where it can prove its worth.

In practice a hook works when it speaks about the viewer, not the poster. 'New autumn collection available in-store' talks about you. 'Does your hair keep breaking after a blow-dry? There's usually one reason' talks about them, and touches a real annoyance they already have in mind. The angles that work almost every time are few: a recognisable problem, a direct question, a common mistake to avoid, a small concrete promise, or something that goes against what everyone assumes.

The fastest way to find one isn't a branding exercise: it's watching what you've already posted. Every week, look at which of your covers made the most people stop and which slid right by, and try to work out what the good ones had in common. Over time you'll notice your business has three or four types of opening that work well with your audience, and that you can reuse them while changing the topic. You don't need to invent something brilliant every time: you need to stop opening with the most predictable sentence.
