Are tag-lines really effective in marketing?

Taglines are often used at the end of a marketing effort. In effect they are your last chance to give your message to a future client.

Many of the writers of marketing blogs promote tag-lines as an opportunity to communicate an idea about your business. Sadly I’ve seen that many tag-lines are really not used effectively.

I say that because if the potential buyer of your product or service doesn’t know enough about you, the tag-line will have no effect at all. Instead of working on your tag-line, start developing better ways to explain in detail what it is that you do from the customers perspective.

It has been proven by experts in the field of marketing that frequently a longer description has more of an impact and is more influential than shorter descriptions.

So when can you improve and lengthen the descriptions of your offering?
