Do you need a tag line? A sentence that encapsulates your business ethos, that sums up your product or service in one sweet phrase.
The ones that work...try and guess the brand from the line.
I'm loving it
Obey your thirst
You're worth it
Be your own label( no? ok, Clarks shoes!)
This website has a great database of tag lines and slogans from all kinds of brands. Great for inspiration or testing that your idea is original (or not!)
Do you have any examples of ones that don't work?
