Sometimes a searcher may claim payment for a site to take a certain position in search lists. These are usually advertisements that cannot be found in natural lists results. There are sponsored search data where such ads appear responding to a specific search term. Usually they are situated on the right side of the page with the results of a searcher. There are lots of factors justifying the sum spent on such a marketing campaign. Moreover, you can decide if to spread the advertisements nationwide or just regionally. Calculation of the price for placement of these ads is made up counting the number of clicks that the ad gets. The quality of the position the Internet site takes depends on the budget of advertising: the position will be better if the budget is higher. Search engine advertising is especially necessary if a site does not take a high position in the lists of search as it is little known or in case of contest for the key term.
