A lot of people call me in order to improve their Internet Marketing Strategy. Many have started with banner ads. Others want to start directly with SEO. My advice to almost everyone is to start with a paid Google Adwords or Yahoo PPC campaign. This way you can quickly find out what works and what doesn’t. This information can then be use to guide you in your SEO, banner ad and other marketing efforts.
Internet marketing demands resources, so it makes sense to do things methodologically and in the right order.
