This essay sheds light on what are pay-per-click marketing campaigns, demystifies the different types of pay-per-click advertisements that can be apart of pay-per-click marketing campaigns, explicates how to launch pay-per-click marketing campaigns, elucidates how to improve your pay-per-click marketing campaigns, delineates the benefits of companies leveraging pay-per-click marketing campaigns, and reveals the metrics that are utilized for measuring the effectiveness of a pay-per-click marketing campaign. Pay-per-click marketing campaigns are marketing campaigns that are comprised of pay-per-click advertisements. Pay-per-click advertisements perish once a company's marketing budget is depleted. Unlike certain other types of advertisements, such as product placement advertisements and specialty advertisements, that have the latent potential to last for centuries on end, pay-per-click advertisements are not perennial advertisements. Pay-per-click advertisements are appealing to companies since leveraging them only depletes marketing dollars in contexts in which they are clicked on. If pay-per-click advertisements earn impressions, but are not clicked on then marketing dollars are not depleted. Yielding clicks on pay-per-click advertisements has a low probability of yielding product sale conversions for companies. Customers detest being solicited with pay-per-click advertisements during their internet browsing sessions. Customers prefer for their internet browsing sessions to be devoid of encounters with advertisements. Companies earnestly hope that only qualified prospective buyers click on their pay-per-click advertisements since advertisement clicks from unqualified prospective buyers not only costs them marketing dollars, but also does not elicit additional product sales for companies. Pay-per-click marketing campaigns differ from pay-per-impression marketing campaigns. Pay-per-impression marketing campaigns yield marketing costs when advertisements that are apart of the pay-per-impression marketing campaigns earn impressions. On the other hand, pay-per-click marketing campaigns yield marketing costs when advertisements that are apart of the pay-per-advertisement campaigns earn clicks. It is much easier for companies to earn impressions on their advertisements than it is for them to earn clicks on their advertisements. Companies often prefer to leverage pay-per-click marketing campaigns in lieu of pay-per-impression marketing campaigns in contexts in which the overarching goal of their marketing campaign is to increase the company's sales volume, sales revenue, and profits. In stark contrast to pay-per-impression marketing campaigns that yield marketing costs every time an advertisement that is apart of a pay-per-impression marketing campaign is viewed, pay-per-click marketing campaign only yield marketing costs whenever an advertisement that is apart of a pay-per-impression marketing campaign is clicked on which renders pay-per-click marketing campaign far more cost effective marketing campaigns than pay-per-impression marketing campaigns. It is beneficent for companies to avail themselves of leveraging pay-per-click marketing campaigns, especially in contexts in which they have a finite marketing budget and do not want to incur marketing costs from viewers of their advertisements who are disinterested in buying their products. Customers who are disinterested in procuring a company's products are inapt to click on the company's advertisements. On the other hand, if the marketing campaign being leveraged by a company is a pay-per-impression marketing campaign instead of a pay-per-click marketing campaign, then customers who view the advertisements of the pay-per-impression marketing campaign will cause the company to incur marketing costs even if the customers who viewed the advertisements of the pay-per-impression marketing campaign are disinterested in buying the company's products. Running pay-per-impression marketing campaigns can be extraordinarily expensive and is far less apt to yield favorable results than employing pay-per-click marketing campaigns, especially since utilizing pay-per-click marketing campaigns can help companies to stretch out their marketing dollars which allows their marketing budgets to last longer and take longer to be depleted. Most customers will desist from clicking on the advertisements of the pay-per-click marketing campaigns unless they are genuinely interested in procuring the advertised products. Since it can however be extraordinarily expensive for a company to run pay-per-click marketing campaigns that yield marketing costs whenever the advertisements that are apart of its pay-per-click marketing campaigns are clicked on, a company should ensure that the products being advertised are enticing enough to sell themselves based on their own merits.
