Lesson #1 – Don’t be insulting.
This may go without saying, but consumers are not big fans of being insulted. As if PETA didn’t get enough flack already, they ran this offensive ad on a Florida billboard in 2009. I don’t know about you, but I’m pretty sure that calling everyone who is not a vegetarian a whale is not necessarily the best way to recruit new supporters. You should build a reputation for quality products and services, not the most offensive advertising.
