Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an internal configuration of an advertisement system according to an embodiment of the present invention. As shown in FIG. 1, the advertisement system 100 according to the present exemplary embodiment includes an advertisement product checking unit 101, a selling price adjusting unit 102, and a selling price determining unit 103.

The advertisement product checking unit 101 confirms the advertisement product to be adjusted to the selling price based on the selling rate of the advertisement product. Here, the selling rate may include a ratio of at least one of a ratio of page views sold to all page views (PVs) according to an advertisement product and a ratio determined according to whether the advertisement area is sold according to the advertisement product. have. For example, when a page view sold for an advertisement product having a total page view of "10,000,000" is "3,000,000", the selling rate may have a value of "0.3" or "30%". As another example, when "15" advertisement areas are sold for an advertisement product having "20" advertisement areas, the selling rate may have a value of "0.75" or "75%". As another example, when one advertisement area is recognized as one advertisement product, a selling rate ("0" or "0%") when one advertisement area is not sold or one advertisement area is sold You can also check the selling rate ("1" or "100%"). That is, the advertisement product checking unit 101 may confirm the selling rate according to the advertising product as in the above examples, and may identify the advertising product to be adjusted for the selling price according to the selling rate.

In this case, the advertisement product checking unit 101 may identify the advertisement product to be adjusted for the selling price by comparing the ratio of the M when the selling price and the predetermined value is N days before the sale time of the advertisement product is closed. . For example, when the selling rate is less than or equal to the ratio M, the advertising product checking unit 101 may check the advertising product as an adjustment target of the selling price. In more detail, when the sale rate is "0.45" (45%) and M is "0.5" (50%) a week before the closing time of the sale of the advertisement product "A", the advertisement product checking unit 101 The advertisement product "A" can be confirmed as an adjustment target of the selling price. Here, the N and the M may be determined based on at least one of the popularity, the average selling rate, and the value input from the manager of each advertisement area according to the advertisement product. The value input from the manager may be input by causing the manager to select one of a plurality of fixed grades, and the plurality of fixed grades may be determined in advance according to the symbolism or content characteristics of each advertisement area.

In addition, an exclusion option may be set to an advertisement product having a history of being sold at a price whose price is not adjusted within N days from the time when the sale of the advertisement product is closed among the advertisement products, and the advertisement product checking unit 101 may Among the advertisement products having a history, the advertisement product with the exclusion option activated may be identified and excluded from the advertisement product to be adjusted. That is, an exclusion option, which is an option of excluding the corresponding advertisement product from the adjustment target, may be set to an advertisement product having a history in which the selling price is not adjusted within the N days, and the advertisement product checking unit 101 may set the advertisement product. The advertisement product with the exclusion option activated may be excluded from the adjustment of the selling price. This history can be confirmed through the existing sales history, and whether to activate the exclusion option can be determined by the administrator of the advertising system 100 or the advertising system 100.

The selling price adjusting unit 102 adjusts the selling price of the identified advertising product. In this case, the selling price adjusting unit 102 may adjust the selling price by applying a discount rate to the selling price at the time N days before the closing time of the selling of the advertisement product. That is, the selling price adjusting unit 102 may apply the discount rate to the selling price once N days before the closing time of the sale of the advertisement product and sell the advertising product at the selling price to which the discount rate is applied until the closing time of the selling. have. For example, the selling price adjustment unit 102 may sell the advertisement product at a selling price of “700,000” in which a discount rate of “30%” is applied to a selling price of “1,000,000” from seven days before the closing time of the sale. have.

In addition, the selling price adjustment unit 102 may adjust the selling price by applying the discount rate to the selling price at a predetermined period from N days before the closing time of the sale of the advertisement product, unlike applying the discount rate at once. . In this case, the discount rate may be calculated based on the remaining time until the time limit for closing the sale every predetermined period. For example, the selling price adjustment unit 102 may sell the advertisement product at a selling price of applying a discount rate of “10%” to the selling price of “1,000,000” every day from seven days before the closing time of the selling. That is, the advertisement product may be sold at a selling price of "900,000" seven days ago and at a selling price of "810,000" six days ago.

Such a discount rate may have a fixed value as in the above example, but may have a relative value such as "30 / (day remaining until the sale is closed-1 day)%". The discount rate may be determined by a manager or a value calculated according to a default value preset in the advertisement system 100 or a selling price adjustment history.

In addition, the selling price adjusting unit 102 may adjust the selling price such that the selling price has a value equal to or greater than a predetermined minimum selling price for each advertisement area according to the advertisement product or the advertisement product. That is, when the selling price to which the discount rate is applied has a value less than the minimum selling price, the selling price adjusting unit 102 may adjust the selling price as the selling price of the corresponding advertisement product. That is, the minimum selling price may be determined and used so that the selling price of the advertising product falls below the minimum selling price so that there is no fear of lowering the value of the advertising product in the long term.

In addition, the selling price adjusting unit 102 may obtain a similar effect to adjusting the selling price by adjusting the page view provided through the same selling price instead of merely adjusting the selling price. For example, the advertisement product may include a product sold as a page view, and in this case, the selling price adjusting unit 102 adjusts the size of the page view provided as the selling price for the advertisement product to adjust the selling price. I can adjust it. That is, by increasing the page view to "2,500,000" for an advertisement product that provides a page view of "2,000,000" at a selling price of "1,000,000", an effect similar to discounting the selling price can be obtained.

The selling price determining unit 103 determines a new selling price after the advertisement product is sold. In this case, the selling price determination unit 103 may determine the selling price before the selling price is adjusted as a new selling price of the advertisement product or determine the adjusted selling price as a new selling price of the corresponding advertisement product. Even in this case, the selling price determining unit 103 may determine that the new selling price has a value equal to or greater than the minimum selling price.

2 is a flowchart illustrating an advertisement method according to an embodiment of the present invention. The advertisement method according to the present embodiment may be performed through the advertisement system 100 described with reference to FIG. 1. In FIG. 2, the advertisement method will be described by describing a process in which each step is performed through the advertisement system 100.

In step S201, the advertisement system 100 confirms the advertisement product to be adjusted the selling price based on the selling rate of the advertisement product. Here, the selling rate may include a ratio of at least one of a ratio of page views sold to all page views (PVs) according to an advertisement product and a ratio determined according to whether the advertisement area is sold according to the advertisement product. have. For example, when a page view sold for an advertisement product having a total page view of "10,000,000" is "3,000,000", the selling rate may have a value of "0.3" or "30%". As another example, when "15" advertisement areas are sold for an advertisement product having "20" advertisement areas, the selling rate may have a value of "0.75" or "75%". As another example, when one advertisement area is recognized as one advertisement product, a selling rate ("0" or "0%") when one advertisement area is not sold or one advertisement area is sold You can also check the selling rate ("1" or "100%"). That is, the advertisement system 100 may confirm the selling rate according to the advertisement product as in the above examples, and may identify the advertisement product to be adjusted to the selling price according to the selling rate. A method of identifying an advertisement product subject to interest adjustment according to the selling rate will be described in more detail with reference to FIG. 3.

In step S202, the advertising system 100 adjusts the selling price of the identified advertising product. In this case, the advertisement system 100 may adjust the selling price by applying a discount rate to the selling price at the time N days before the closing time of the sale of the advertisement product. That is, the advertisement system 100 may apply the discount rate once to the selling price N days before the closing time of the sale of the advertisement product and sell the advertising product at the selling price to which the discount rate is applied until the closing time of the sale. . For example, the advertisement system 100 may sell the advertisement product at a selling price of “700,000” in which a discount rate of “30%” is applied to the selling price of “1,000,000” from seven days before the closing time of the sale. .

In addition, the advertisement system 100 may adjust the selling price by applying the discount rate to the selling price at regular intervals starting from N days before the closing time of the sale of the advertisement product, unlike applying the discount rate at once. In this case, the discount rate may be calculated based on the remaining time until the time limit for closing the sale every predetermined period. For example, the advertisement system 100 may sell the advertisement product at a selling price of applying a discount rate of "10%" to a selling price of "1,000,000" every day from seven days before the closing time of the sale. That is, the advertisement product may be sold at a selling price of "900,000" seven days ago and at a selling price of "810,000" six days ago.

Such a discount rate may have a fixed value as in the above example, but may have a relative value such as "30 / (day remaining until the sale is closed-1 day)%". The discount rate may be determined by a manager or a value calculated according to a default value preset in the advertisement system 100 or a selling price adjustment history.

In addition, the advertisement system 100 may adjust the selling price to have a value equal to or greater than a predetermined minimum selling price for each advertisement area according to the advertisement product or the advertisement product. That is, when the selling price to which the discount rate is applied has a value less than the minimum selling price, the advertisement system 100 may adjust the minimum selling price as the selling price of the corresponding advertisement product. That is, the minimum selling price may be determined and used so that the selling price of the advertising product falls below the minimum selling price so that there is no fear of lowering the value of the advertising product in the long term.

In addition, the advertisement system 100 may obtain an effect similar to adjusting the selling price by adjusting the page view provided through the same selling price instead of simply adjusting the selling price. For example, the advertisement product may include a product sold as a page view, and in this case, the advertisement system 100 adjusts the selling price by adjusting the size of the page view provided at the selling price for the advertisement product. Can be. That is, by increasing the page view to "2,500,000" for an advertisement product that provides a page view of "2,000,000" at a selling price of "1,000,000", an effect similar to discounting the selling price can be obtained.

In step S203, the advertising system 100 determines a new selling price after the advertising product is sold. In this case, the advertisement system 100 may determine a selling price before the selling price is adjusted as a new selling price of the advertisement product or determine the adjusted selling price as a new selling price of the corresponding advertisement product. Even in this case, the advertisement system 100 may determine that the new selling price is greater than or equal to the minimum selling price.

3 is a flowchart illustrating a method of adjusting a selling price of an advertisement product according to an embodiment of the present invention. Here, the steps S301 to S304 may be performed by the advertisement system 100 described with reference to FIG. 1 as included in the step S201 described with reference to FIG. 2 as shown in FIG. 3.

In step S301, the advertisement system 100 compares the ratio of the predetermined M to the sales rate when N days before the end of the sale of the advertisement product, and in step S302, the sales rate is the ratio of M. In the following case, step S303 may be performed. In addition, when the selling rate exceeds the ratio of M in step S302, it may be terminated without adjusting the selling price of the corresponding advertisement product. In this case, in step S303, the advertisement system 100 may identify the advertisement product whose sale rate is equal to or less than the ratio of M as the advertisement product that is to be adjusted for the selling price. For example, the advertising system 100, when the sale rate is "0.45" (45%) and the M is "0.5" (50%) a week before the closing time of the sale of the advertisement product "A", The advertisement product "A" can be confirmed as an adjustment target of the said selling price. Here, the N and the M may be determined based on at least one of the popularity, the average selling rate, and the value input from the manager of each advertisement area according to the advertisement product. The value input from the manager may be input by causing the manager to select one of a plurality of fixed grades, and the plurality of fixed grades may be determined in advance according to the symbolism or content characteristics of each advertisement area.

In addition, an exclusion option may be set to an advertisement product having a history of being sold at a price for which the selling price is not adjusted within N days from the time limit for the sale of the advertisement product among the advertisement products, and the advertisement system 100 in step S304. ) May identify the advertisement product having the exclusion option activated among the advertisement products having the history and exclude the advertisement product to be adjusted. That is, an exclusion option, which is an option of excluding the corresponding advertisement product from the adjustment target, may be set to an advertisement product having a history in which the selling price is not adjusted within the N days, and the advertisement system 100 may include the exclusion option. This activated advertising product can be excluded from the adjustment of the selling price. This history can be confirmed through the existing sales history, and whether to activate the exclusion option can be determined by the administrator of the advertising system 100 or the advertising system 100.

As such, by using the advertising system or the advertising method according to an embodiment of the present invention, by adjusting the selling price of the advertising product in accordance with the market demand, it is possible to improve the sluggish sales of the advertising product that is low in demand or low in popularity. In addition, the price elasticity of the advertising product can be increased. In addition, by lowering the selling price or increasing the page view for an ad product whose sales rate is less than a certain rate, the advertiser can afford to buy an ad product with low demand at a lower price and execute the ad. It is possible to increase the advertising sales rate by increasing and lowering the selling price of the advertising product.

4 to 7 are tables illustrating various examples of information on which the selling price is adjusted in the advertisement system according to an embodiment of the present invention. Here, the tables 400 to 700 illustrated in FIGS. 4 to 7 show information on the daily sales rate, the selling price, and the page view seven days before the sale closing time.

Table 400 shown in FIG. 4 shows an example in which a discount rate of "30%" is applied to the selling price once when N is "5" and M is "50%". That is, since the selling rate corresponding to "5 days ago" is "35%" and has a value less than the ratio of "50%", the advertising system 100 may check the corresponding advertisement product as the adjustment price of the selling price, and the discount rate The advertisement product may be sold at a selling price of “3,500,000” in which “30%” is applied to an existing selling price of “5,000,000”. In addition, the table 400 indicates that the advertisement product is sold at the selling price to which the discount rate is applied until the closing time, regardless of the selling rate.

Table 500 shown in Fig. 5 is an example in which a discount rate of "10%" is applied to the sales price every day starting from "5 days before" the sale closing time when N is "5" and M is "50%." Indicates. That is, since the selling rate corresponding to "5 days ago" is "35%" and has a value less than the ratio of "50%", the advertising system 100 may check the corresponding advertisement product as the adjustment price of the selling price, and the discount rate The advertisement product may be sold at a selling price of “4,500,000” in which “10%” is applied to the existing selling price “5,000,000”. Thereafter, the advertisement system 100 may sell the advertisement product at a selling price that overlaps the discount rate of “10%” every day. Here, the discount rate may have a fixed value, such as "10%" as described above, but as described with reference to Figures 1 and 2 "30 / (day remaining until the time the sale is closed-1 day)% It may have a relative value such as ". For example, a fixed value of "10%" may be used as a discount rate in the table 500, but a discount rate of "30 / (5-1)% = 7.5%" is "5 days ago". 4 days ago, a discount rate of "30 / (4-1)% = 10%" may be applied to the selling price.

Table 600 shown in FIG. 6 shows an example in which a discount rate of "30%" is applied to the page view once when N is "5" and M is "50%". That is, since the sales rate corresponding to "5 days ago" is less than the ratio of "50%" to "35%", the advertising system 100 can confirm the advertisement product as an adjustment target of the selling price. The advertisement product may be sold at the same selling price, but may be set to provide a page view of "1,300,000" in which the discount rate "30%" is applied to the existing pageview "1,000,000". In addition, the table 600 may be sold at the same selling price until the closing time, regardless of the selling rate, and the discount rate may be applied repeatedly.

Table 700 shown in FIG. 7 shows an example in which a discount rate of "10%" is applied daily to page views starting from "5 days before" the sale closing time when N is "5" and M is "50%." Indicates. That is, since the sales rate corresponding to "5 days ago" is less than the ratio of "50%" to "35%", the advertising system 100 can confirm the advertisement product as an adjustment target of the selling price. The advertisement product may be sold at the same selling price, but may be set to provide a page view of "1,100,000" in which the discount rate "10%" is applied to the existing page view "1,000,000". Thereafter, the advertisement system 100 may set the advertisement product such that the daily page view is increased by the discount rate "10%". That is, "4" days ago "may be set to provide a page view of" 1,210,000 "when purchasing the advertising product at the same selling price, where the discount rate is left until the closing time, as is applied to the selling price. Depending on the day, relative values can be applied to the pageview.
