You need frequency in all your marketing efforts to achieve results. Marketing experts state that it takes 9 exposures in order for people to see your message 3 times before they buy. Exposures can combine various media and activities such as print advertising, trade shows, and sales efforts. Frequency also ensures that your company is in front of prospects when they’re ready to buy, which may not be the day your salesperson calls. If you have a choice to place one large ad or a series of smaller ads, your best investment is a series of ads.
