What is Hook?
A hook is the idea that grabs attention and makes someone want to watch.
Hook explained
The hook is the reason to click: a question, a surprising result, a challenge, a conflict. Thumbnail, title and the first seconds of the video should all deliver the same hook.
If you can’t say your hook in five words, the thumbnail will struggle to communicate it. Try thumbnail text ideas to sharpen it.
Why it matters for thumbnails
Thumbnails are the first thing viewers see, so they influence how hook plays out on your channel. Read our thumbnail best practices to put this into practice, or browse the rest of the glossary.
