Search engine advertising is usually a part of a marketing or branding strategy. One of the primary objectives of SEA is to increase the ''click-through rate'' since the number of clicks on a website can quickly be increased through the posting of advertisement space
Before publishing an ad in the most common search engines, is important to define keywords that correspond to the search terms that internet users use to reach this or other similar themed pages that are relevant to the advertiser page.
The elaborate set of keywords is used to create the advertising texts and, finally, the price that the company is willing to pay for each click made by users will be fixed.
