What role does online marketing play?

Online marketing plays an important role in marketing any business, product, or service. People rely on the internet to find almost anything, and with the advent of search engines, there is little need for certain aspects of traditional listings in offline directories like phone books, etc.
A properly optimized website can produce much greater results than an advertisement in a phone book. Search engine optimization plays a huge role in modern marketing strategies. Also, search engine marketing, another aspect of online marketing, produces quick results and can increase traffic to your website dramatically in a short period of time.
