METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR MANAGING ADVERTISER'S DEPOSIT FOR SEARCH ADVERTISEMENT}

The present invention relates to a method, system and computer readable recording medium for managing an advertiser's deposit for a search advertisement. More specifically, the present invention is to manage the advertiser's deposit for the search advertising by maintaining the advertiser's deposit balance to be more than the advertising charges in order to ensure a stable payment of the advertising fee for the search advertising purchased by the advertiser A method, system and computer readable recording medium.

As information acquisition through Internet search has become commonplace, recently, search advertisement (Search Advertisement), which provides an advertisement related to a search clue (for example, a search keyword or a search category) input from a user through a search site, has been widely used. . Here, in the case of a search advertisement, when a user searches with a specific search clue on a search site, advertisement information such as an advertiser's web page address, a single line advertisement message, and an image advertisement may be displayed at a specific position on the search result page. Is an advertising technique.

According to these search advertisements, the advertisement is not unconditionally exposed to an unspecified number of people, but the advertisement is provided only to the users who searched with the search clues associated with the specific advertisement, so the possibility of using the product or service provided by the advertiser is relatively low. Because of the advantage that targeted advertising is provided only to high potential customers, search advertising is in the spotlight in recent years and its range of use is gradually expanding.

On the other hand, as in the case of ads using other media, advertisers paying for search ads and ad sellers selling search ads can determine whether advertisers can effectively serve search ads within a limited advertising budget. As a primary concern, several methods have been developed to reasonably charge for search advertising in accordance with these needs. As a specific billing method, a cost per mill (CPM) method for calculating an advertising cost according to the number of times an advertisement is exposed to a user, a cost per action (CPA) method for calculating an advertising cost according to a result of the user's action, Cost Per Click (CPC) method, which calculates an advertising cost based on the number of clicks on a web page containing advertisement information, etc.), and Cost Per Time (CPT) method, which calculates an advertising cost based on the time the ad is displayed. Etc.

In addition, as in the case of advertisements using other media, advertisers cannot spend unlimited advertising costs for search ads, and it is not desirable for an advertisement seller to generate an advertisement fee that is not guaranteed by the advertiser. In order to enter into a contract for providing a search advertisement according to a predetermined billing standard, the advertiser deposits a certain amount to the advertisement seller.

However, since the amount of advertising spending for search ads may vary depending on the situation, if the payment is made only within the range of the advertiser's deposit, the advertising cost increases unexpectedly and the advertiser's deposit is rapidly exhausted. May not be able to make payments normally. That is, even though the purchase or successful bid for the search advertisement is made effective, the payment of the advertisement fee is not made due to the lack of a deposit, and as a result, the advertiser's search advertisement may not be displayed as intended. In this case, the advertiser does not enjoy the intended advertising effect, and there is a problem that the opportunity of the loss due to non-payment of advertising costs from the position of the advertising seller.

In particular, the above problem may be more serious when the purchase balance of the advertiser is likely to fluctuate during the time between the purchase time and the payment time due to a mismatch between the purchase time and the payment time for the search advertisement.

For example, an advertiser who has already purchased a large number of search ads purchased a new Search Ad A with an advertising cost of $ 400,000 on September 20, 2008, and the payment deadline for Search Ad A was Assume the case at 17:00 on the 25th of the month. Here, since the purchase time and the payment time of the plurality of search ads purchased by the advertiser may be different, even if the advertiser charges his deposit by 400,000 won to pay for the advertisement at the time of purchase of the search advertisement A, You may make a payment of $ 20 for other Search Ads B prior to the payment for Ad A for Ad A, in which case your Advance Deposit is only $ 20 at the time you pay for Search Ad A As a result, payment of the advertisement fee for the search advertisement A may not be performed normally. Furthermore, if the deposit is insufficient and the time limit for the payment of the advertising fee for the search advertisement A has passed 17:00, September 25, 2008, the advertiser can no longer pay the advertising fee for the search advertisement A. As a result, there arises a problem that the search advertisement A cannot be published.

Can be included.

In addition, the information acquisition unit 210 according to an embodiment of the present invention may perform a function of constructing the database 250 by storing the obtained purchase information and payment information. In detail, the information acquisition unit 210 may charge the billing information according to a specific advertiser or a specific search advertisement so that the calculation of the unpaid advertising fee performed by the advertising fee outstanding amount calculation unit 220 is performed as described below. Database 250 can be built by processing or indexing. A detailed configuration of the database 250 constructed by the information acquisition unit 210 will be described later.

Next, the advertising fee outstanding amount calculation unit 220 according to an embodiment of the present invention is an advertising cost for at least one search advertisement purchased by the advertiser using the purchase information and payment information obtained by the information acquisition unit 210. Perform the function of calculating the outstanding balance. Here, the unpaid amount of advertising costs means the amount of the advertising costs for the search ads purchased by the advertiser that have not been paid yet. In order for the search ads to be displayed normally, the outstanding amount of the related advertising costs must be paid. . For example, the unpaid advertising fee may be determined by limiting the amount of the upfront payment for the at least one search advertisement purchased by the advertiser from the sum of all the advertising costs for the at least one search advertisement purchased by the advertiser.

According to an exemplary embodiment of the present invention, the unpaid advertising fee calculating unit 220 may calculate an unpaid advertising fee for all search ads purchased by the advertiser, and only pays a portion of the search advertising purchased by the advertiser. You can also calculate the payment amount. For example, the advertising fee outstanding amount calculation unit 220 may calculate an advertising fee outstanding amount only for a search advertisement selected by the advertiser as having a relatively high importance among a plurality of search advertisements purchased by the advertiser. An outstanding advertising fee may be calculated only for a search advertisement charged by a specific billing method (CPM method, CPT method, etc.) among a plurality of search advertisements.

In addition, according to a preferred embodiment of the present invention, the advertising fee outstanding amount calculation unit 220 may calculate the advertising fee outstanding amount at any point in order to smoothly perform the deposit balance management to be described later, more preferably May calculate the amount of the advertising expenses outstanding in real time.

3 is a diagram exemplarily illustrating a situation in which an advertising fee outstanding amount for a search advertisement purchased by an advertiser is calculated according to an embodiment of the present invention. For reference, in the text boxes corresponding to the advertisements A, B, C, and D illustrated in FIG. 3, the amount described in each text box means an advertisement fee for each advertisement, and the starting point of each text box corresponds to The point of time when the purchase of the advertisement is made, and the end of each text box means the point of time when the payment for the advertisement cost of the corresponding advertisement is made.

Referring to FIG. 3, an advertiser has made purchases or payments for four search advertisements (Ads A, B, C, and D) during the period of October 1, 2008 to October 7, 2008, respectively. According to this, purchases for ads A, B, C, and D were made on October 1, October 2, October 3, and October 1, respectively, and the advertising costs for ads A, B, C, and D were Payments were made on October 4, October 7, October 5 and October 6, respectively. The advertising fee outstanding amount calculation unit 220 according to an embodiment of the present invention may calculate the advertising fee outstanding amount for only a part of the search advertisement purchased by the advertiser, for example, it is determined that the importance is high in terms of advertising effect. Advertisement costs are calculated only for the advertisements B and C that are to be used as the basis of the deposit balance management to be described later. In addition, the advertising fee outstanding amount calculation unit 220 according to an embodiment of the present invention may calculate the advertising cost outstanding amount for all the search advertising purchased by the advertiser, in this case, the advertising cost outstanding amount calculated for all the search advertising May be used as a reference for deposit balance management to be described later. However, the above-mentioned advertising costs outstanding amount calculation method is merely an example for explaining the function of the advertising costs outstanding amount calculation unit 220 according to various embodiments of the present invention, the advertising costs outstanding amount calculation method according to the present invention This is not necessarily limited to this.

Next, the deposit balance management unit 230 according to an embodiment of the present invention, the advertiser's deposit balance is more than a predetermined amount on the basis of the advertisement fee outstanding amount calculated by the advertising cost outstanding amount calculation unit 220. To manage the function. That is, the deposit balance management unit 230 maintains the deposit balance of the advertiser above the amount of the advertising fee for the search advertisement purchased by the advertiser, so that the payment for the amount of the advertising fee outstanding can be made stable.

As a specific method for managing the deposit balance of the advertiser as described above, the deposit balance management unit 230 may perform a function of automatically filling the deposit of the advertiser. Here, when the automatic deposit is made and the amount of the deposit may be determined based on the deposit balance of the advertiser, the purchase status of the search advertisement of the advertiser, and the like, so that the deposit balance of the advertiser is equal to or greater than the amount of the advertising charges of the advertiser. It can be changed as appropriate within the scope. For example, if an advertiser automatically charges a deposit at the time of a new search ad purchase, the advertiser's deposit may be automatically charged in full for the search ad, whereas the advertiser may purchase a search ad. Then, when the deposit is automatically charged after a predetermined time has elapsed, the advertiser's deposit may be automatically filled with only the amount of the advertisement fee for the search advertisement excluding the amount prepaid for the predetermined time. On the other hand, in order to prevent the automatic charge deposit is made against the intention of the advertiser, it is a matter of course that the automatic filling can be performed only when the consent for the automatic deposit of the deposit from the advertiser.

According to an exemplary embodiment of the present invention, the deposit balance manager 230 may manage the deposit balance based on the amount of the advertising charges calculated for all the search advertisements purchased by the advertiser. The balance of the deposit may be managed based on the amount of the advertising charges calculated for only some of the search ads. For example, the deposit balance management unit 230 is a relatively high importance among the search advertisements purchased by the advertiser, based on the unpaid amount of the advertising costs calculated only for the search advertisement selected by the advertiser, and the deposit balance of the advertiser is It can be managed to be more than the amount of the advertising charges. For another example, the deposit balance management unit 230 is based on the amount of the advertising charges calculated only for the search advertising billed by the specific billing method (CPM method, CPT method, etc.) of the search advertising purchased by the advertiser. You can also manage your deposit balance. However, the search advertisement within the scope of the deposit balance management is not necessarily limited thereto, and as long as the search advertisement may not be paid normally because the purchase time and the payment time do not coincide with the deposit balance management of the present invention, Make it a target.

In addition, according to an exemplary embodiment of the present invention, the deposit balance manager 230 may manage the deposit balance of the advertiser in real time based on the amount of the advertising charges calculated in real time as described above.

In addition, according to an embodiment of the present invention, the deposit balance management unit 230, if the time limit for the payment of the advertising costs for the corresponding search advertising has not been completed, the payment of the advertising costs for the search ads, In order to pay for the advertising fee for the advertiser may be able to perform a function that refunds the amount charged to the deposit of the advertiser. As such, when the payment deadline for the search advertisement has elapsed and the payment for the advertisement is no longer possible, it is no longer necessary to add a deposit for the search advertisement, and thus the advertiser has made a deposit for the payment of the advertisement. By refunding, it is possible to increase the flexibility of the advertising budget from the advertiser's point of view, it is possible to obtain the advertiser's trust from the advertising seller.

Meanwhile, it may be assumed that an advertiser purchases a search advertisement charged by the CPC method. Unlike CPM Search Ads or CPT Search Ads, which charge you a fixed amount based on the number of times your ad is shown or how long it's run, the cost of CPC search ads is variable depending on the number of clicks on your users. In this case, the advertising fee charged for the search advertisement increases, and as the payment is made, the deposit balance of the advertiser may be unexpectedly exhausted. Therefore, in some cases, due to the payment of advertising costs for CPC search ads, the advertiser's deposit balance is insufficient, and the advertising costs for the remaining search ads (for example, CPM search ads or CPT search ads) among the search ads purchased by the advertiser. There may be a problem that can not be paid normally.

In order to solve this problem, the deposit balance management unit 230 according to an embodiment of the present invention, in the management of the deposit balance of the advertiser, at the same time considering the balance of the advertising costs of the advertiser, the CPC purchased by the advertiser Consider further advertising costs that are expected to be charged for search advertising. Specifically, the deposit balance management unit 230 is a sum of the advertiser's deposit balance calculated by the advertising expense outstanding balance calculation unit 220 and the estimated advertising cost for the CPC search ads purchased by the advertiser. Can be managed to be more than the amount.

On the other hand, the estimated advertising costs for CPC search ads are indicators (e.g., the number of times a search ad is displayed, the number of user clicks on the search ad, and the click through rate of the search ad) for the CPC search ad. Can be determined based on statistical information regarding Since a technique for calculating an expected advertisement cost for a CPC search advertisement is already widely used in the art as a known technique, a detailed description thereof will be omitted.

4 is a diagram illustrating a situation in which a deposit balance of an advertiser is managed according to an embodiment of the present invention.

Referring to FIG. 4, it may be assumed that a deposit balance of an advertiser is managed during a period from October 1, 2008 to October 7, 2008. Deposit balance management unit 230 according to an embodiment of the present invention, the advertiser's deposit balance based on the amount of the advertising charges for the other search advertising purchased by the advertiser and the estimated advertising cost for the CPC search advertising purchased by the advertiser. It can be managed to be equal to or more than the sum of the outstanding advertising costs and the expected advertising costs. In particular, according to an embodiment of the present invention, even if the amount of the outstanding advertising costs dropped to 10,000 won, as in October 7, even if the estimated advertising costs for CPC search exploded to 90,000 won, By maintaining an advertiser's deposit balance of 100,000 won, it is possible to ensure stable payment of advertising costs for all search ads purchased by the advertiser. However, the above-described deposit balance management method is merely an example for explaining the function of the deposit balance management unit 230 according to various embodiments of the present invention, the deposit balance management method according to the present invention is limited thereto. It doesn't happen.

Next, the automatic payment unit 240 according to an embodiment of the present invention automatically pays the advertising costs for the search advertising purchased by the advertiser using the deposit balance of the advertiser managed by the deposit balance management unit 230.
