as one of the emerging network marketing methods, search engine marketing (SEM) has been favored by many enterprises. In particular, a large number of small and medium enterprises, because of insufficient funds, please do not promote professional talent, can not afford to invest in traditional advertising, so the search engine marketing as a preferred means of business promotion. Even during the two sessions this year, more than NPC deputies suggested that the search engine marketing should be written into the SME Promotion law.
, however, from my experience for many years engaged in the Internet, search engine marketing easy entry, seemingly in Baidu, Google and other search engines can open an account, but if you want to do, is not an easy thing. Whether it is keywords, creativity, selection, delivery, bidding, or ranking management, all of them need some professional knowledge and experience.
