5. RECURRENT AND TERM OF AGREEMENT: The duration of each advertising service begins on the date the advertiser accepts these terms and conditions. Billing takes the form of a one-time furnishing payment and an automatic monthly payment, as stated in the specific service/product conditions mentioned in an order agreement between the two parties. In addition to ads on SERPs, large ad networks allow contextual ads to be displayed on third-party properties with which they have partnered. These publishers sign up to host ads on behalf of the network. In exchange, they receive a portion of the advertising revenue generated by the network, which can range from 50% to more than 80% of the gross revenue of advertisers. These properties are often called content networks and the ads on them are contextual ads, because the ads are associated with keywords based on the context of the page where they are found. In general, ads on content networks have a much lower click-through (CTR) and conversion rate (CR) than ads on serps and are therefore less valued. Content network features may include websites, newsletters and emails.

Pay-per-Click (PPC) is an Internet advertising model that is used to promote traffic to websites, in which an advertiser pays a publisher (usually a search engine, website owner or web network) when clicked on the ad. Google started in December 1999 with search engine advertising. It was not until October 2000 that the AdWords system was introduced, which allowed advertisers to create text ads for placement in the Google search engine. However, the CPP was not introduced until 2002; Until then, ads were calculated at a cost per thousand impressions or per thousand (CPM). Overture filed a infringement lawsuit against Google and explained that the competing search service exceeded its limits with its ad placement tools.  As a general rule, the contextual advertising system (Google AdWords, Yandex.Direct, etc.) uses an auction approach as an advertising payment system. In February 1998, Jeffrey Brewer of Goto.com, a 25-employee start-up (later Overture, now part of Yahoo!), presented a proof-of-concept search engine per click at the TED conference in California.
 This presentation and the events that followed created the PPC advertising system. The PPC model concept is generally attributed to Idealab and Goto.com founder Bill Gross.  Pay-per-Click, with cost per print (CPM) and cost per order, are used to assess the profitability and profitability of internet marketing. In Cost Per Thousand Impressions (CPM), the advertiser pays only for the 1000 impressions of the ad. Pay-per-Click (PPC) has an advantage over cost per print because it provides information on the effectiveness of advertising. Clicks are a way to measure attention and interest; If the main purpose of an ad is to generate a click or drive traffic specifically to a destination, Pay-per-Click is the preferred metric.
