Search engine marketing is a way to create and edit a website which can be relative to the search engines than other pages. It should be also focused on keyword marketing or pay-per-click advertising (PPC). The technology enables advertisers to bid on specific keywords or phrases and ensures ads appear with the results of search engines.With the development of this system, the price is growing under the high level of competition. Many advertisers prefer to expand their activities, including increasing search engines and adding more keywords. The more advertisers are willing to pay for clicks, the higher the ranking for advertising, which leads to higher traffic.[15] PPC comes at a cost. The higher position is likely to cost $5 for a given keyword, and $4.50 for a third location. A third advertiser earns 10% less than the top advertiser, while reducing traffic by 50%.[16] The investors must consider their return on investment and then determine whether the increase in traffic is worth the increase.
