As a general rule there are good times and bad times to advertise. Of course it depends on the industry, but warm weather is typically not as effective as colder months. Why? Think about your habits when the nice weather hits. Are you reading less ads and playing more golf or outside gardening? So put yourself in the target audiences shoes and ask yourself…would you be more or less inclined to read your ad at this time of year? Remember, marketing is an investment. Make sure you're getting the best returns for your money.
