Step one: choose the promise and the audience
Start with one sentence saying who the brand speaks to and what they gain. Worked example: Yaradi as a handmade crafts shop speaking to home decorators who want pieces with a maker's story. The promise becomes finding objects that feel personal. Write this sentence at the top of the sheet and test every later line against it. If a caption or headline does not serve that audience and promise, cut it. Keeping the first decision narrow prevents the voice from drifting into generic lifestyle language that could belong to any shop.

Step two: set three voice traits with examples
Pick three traits and give each a do and a avoid-style example in plain words. For the crafts example, the traits might be warm, specific and unhurried. Warm means greeting a visitor like a neighbor. Specific means naming the clay, the dye or the maker's town. Unhurried means short sentences with no pressure phrases. Add one sample product description written in that voice. A teammate or freelancer should be able to read the traits and the sample, then produce a similar paragraph without asking questions or guessing about tone.

Step three: draft and test tagline options
Write six taglines in different styles: a benefit, a feeling, a command, a question, a place-based line and a short rhythm line. For the crafts example, options could include Made by hand, kept for years or Find the piece with a story. Read each aloud beside the name, because Yaradi has a strong cadence. Check length for a banner and a label, then ask five target shoppers which line they would repeat. Keep one primary tagline, one backup and a note on where each belongs in the brand.
