Do you need a logo before you start advertising?

Waiting for the perfect logo before running your first ad is a very common way to advertise nothing for six months.

What an ad actually needs is consistency, not polish: the same name, the same colour, the same feel, showing up the same way every time someone sees it. A plain wordmark used consistently beats a beautiful logo that isn't finished yet.

The logo will improve. It always does, over years, as the business does. What it can't do is retroactively fix the months you spent not advertising while you waited for it.

Start with something simple and repeat it. Repetition is doing more of the branding work than the design ever will.
