You have to have a good understanding of the target market and where high traffic exists.What are those in the areas where people in your target market are likely to gather? Similarly,you have to think about the timing of your campaign.On what days and at what times are you likely to reach your target market? You also must remember that guerrilla marketing can be difficult to measure.What,exactly,will indicate that your campaign is a success or a failure? Monitoring social media is a good way to start seeking correlations between the campaign and sales.You must also consider the community in which your campaign will take place; don't be tone-deaf.Think about morality and legality.
