DESCRIPTION OF THE EMBODIMENTS

(9) Reference will now be made in detail to the exemplary embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

(10) The present disclosure describes systems and methods for addressing limitations associated with traditional third party cookies, by allowing both third party ad networks and publishers to interact with cookies on browsers set to allow only first party cookies, while adhering to browser privacy settings. In one embodiment, addressing these limitations may generally involve: (1) first, setting a cookie on a user's browser, the cookie having the advertiser's domain and being served from a third party cookie server; and (2) second, checking, at a third party publisher website, for the existence of that cookie using an ad tag that does not necessarily match the advertiser's domain.

(11) In one embodiment, a method of performing these tasks may be described as involving three stages, which are separated in time. In a first stage, an advertiser participating in a method of targeting based on first party cookies may update its DNS record to include a subdomain that redirects to a server associated with an ad network. In a second stage, the ad network may incorporate that advertiser's subdomain in an ad pixel tag published on one or more of the advertiser's web pages, to set a cookie on the advertiser's domain. Specifically, when a user visits one of the advertiser's web pages, the ad pixel tag may be redirected by the advertiser's DNS update to an ad network server for receipt of a cookie that matches the subdomain. In a third stage, the ad network may distribute to its publishers an ad call that checks for the presence of any first party domain cookies set via the second stage, and then pass any such cookie data to the network's ad servers to decide which ad to serve. Specifically, the ad call may rotate through all subdomains set by advertisers via the second stage, and call a URL associated with each domain to determine whether the cookie is present. For each domain having a matched cookie, that cookie's data may be passed to the network ad server for an ad decision.

(12) FIG. 1 is a schematic diagram of an environment in which electronic advertising may be performed consistent with these methods and a system for accessing first party cookies and performing electronic advertising, according to an exemplary embodiment of the present disclosure. Specifically, FIG. 1 illustrates an exemplary environment including a plurality of user devices 102, advertiser web servers 104, publisher web servers 106, DNS servers 108, ad servers 110, and ad pixel servers 112, all disposed in communication with an electronic network 100, such as the Internet.

(13) In one embodiment, user devices 102 may be owned and used by one or more people, who may be viewers of web pages over the Internet, either through a mobile browser or web browser stored on respective user devices. User devices 102 may include any type of electronic device configured to send and receive data, such as websites and electronic advertisements, over electronic network 100. For example, each of user devices 102 may include a server, personal computer, tablet computer, mobile device, smartphone, and/or personal digital assistant (“PDA”) disposed in communication with electronic network 100. For example, in one embodiment, each of user devices 102 may be a handheld device, such as an Apple iPhone, Apple iPad, Samsung Galaxy, Amazon Kindle, Microsoft Surface, or any other equivalent or similar device. Each of user devices 102 may have a web browser or mobile browser installed for receiving and displaying web and/or ad content from web servers. Thus, each of user devices 102 may be configured to receive and display data that is received from one or more of advertiser web servers 104, publisher web servers 106, DNS servers 108, ad servers 110, and/or ad pixel servers 112, over electronic network 100.

(14) Advertiser web servers 104 may be owned and/or operated by any entities having content, such as online advertisements (e.g., display ads, banner ads, pop-ups, etc.) desired to be delivered to online users. Advertisers may interact with user devices 102, publisher web servers 106, DNS servers 108, ad servers 110, and/or ad pixel servers 112, through advertiser web servers 104 connected to electronic network 100. Thus, advertisers may be able to communicate advertising information, such as ad information, targeting information, consumer information, budget information, bidding information, etc., to other entities in the environment of FIG. 1.

(15) Publisher web servers 106 may be owned and/or operated by any entities having inventories of available online advertising space. For example, publishers may include online content providers, search engines, e-mail programs, or any other online site or program having online user traffic. Publishers may interact with user devices 102, advertiser web servers 104, DNS servers 108, ad servers 110, and/or ad pixel servers 112, through publisher web servers 106 connected to electronic network 100. Thus, publishers may be able to communicate inventory information, such as site information, demographic information, cost information, etc., to other entities in the environment of FIG. 1.

(16) DNS servers 108 may include name servers that host a network service for providing responses to queries against a directory service. Specifically, DNS servers 108 may map a human-recognizable identifier to a systematic, e.g., numeric, identification or addressing component according to a network service protocol, such as numeric Internet Protocol (IP) addresses. DNS servers 108 may also identify and locate computer systems, servers, and other resources on the Internet. DNS servers 108 may interact with user devices 102, advertiser web servers 104, publisher web servers 106, ad servers 110, and/or ad pixel servers 112 over electronic network 100.

(17) Ad servers 110 and ad pixel servers 112 may include any type of servers configured to process advertising information from advertisers and/or site information from publishers, and send and receive ad requests and information from user devices 102, either directly or indirectly. In one embodiment, ad servers 110 and/or ad pixel servers 112 may be owned and operated by an ad network 114. Ad network 114 may be a business that receives ad buys from advertisers, and serves ads on inventory supplied by publishers. Thus, ad network 114 may collect money from advertisers, and purchase impressions from publishers.

(18) In certain embodiments, ad servers 110 and ad pixel servers 112 may be remote web servers that receive advertising information from advertisers and serve ads to be placed by publishers. Ad servers 110 and ad pixel servers 112 may be configured to serve ads across various domains of publishers, for example, based on advertising information provided by advertisers. Ad servers 110 and ad pixel servers 112 may also be configured to serve ads based on contextual targeting of web sites, search results, and/or user profile information. In some embodiments, ad servers 110 and ad pixel servers 112 may be configured to serve ads based on ad tags served by advertiser web servers 104 and/or publisher web servers 106, and on ad requests received from user devices 102. Ad servers 110 and ad pixel servers 112 may be configured to send and receive data from user devices 102, advertiser web servers 104, publisher web servers 106, and/or DNS servers 108, over electronic network 100.

(19) Ad servers 110 and ad pixel servers 112 may include any type or combination of computing systems, such as clustered computing machines and/or servers. In one embodiment, each of ad servers 110 and ad pixel servers 112 may be an assembly of hardware, including a memory, a central processing unit (“CPU”), and/or a user interface. The memory may include any type of RAM or ROM embodied in a physical storage medium, such as magnetic storage including floppy disk, hard disk, or magnetic tape; semiconductor storage such as solid state disk (SSD) or flash memory; optical disc storage; or magneto-optical disc storage. The CPU may include one or more processors for processing data according to instructions stored in the memory. The functions of the processor may be provided by a single dedicated processor or by a plurality of processors. Moreover, the processor may include, without limitation, digital signal processor (DSP) hardware, or any other hardware capable of executing software. The user interface may include any type or combination of input/output devices, such as a display monitor, touchpad, touchscreen, microphone, camera, keyboard, and/or mouse.

(20) Regardless of specific physical components or layout, one or more of ad servers 110, ad pixel servers 112, or any other servers or systems associated with ad network 114, may be programmed with instructions to perform a method of setting and accessing first party cookies according to the exemplary disclosed methods, such as the exemplary methods described with respect to FIGS. 2-6B below.

(21) FIG. 2 is a flow diagram of a method for setting first party cookies for targeting electronic advertising (i.e., in a second stage, as discussed above), according to an exemplary embodiment of the present disclosure. Specifically, as discussed above, a method of setting first party cookies for targeting electronic advertising may include a user first visiting an advertiser website 200 (depicted as “advertiser.com”) using a user device 204. Advertiser website 200 may include web content and an ad pixel tag 202. In general, when a user device 204 visits advertiser website 200, the user device 204 may receive from the advertiser both the web content and an ad call. Specifically, the user device 204 may receive, e.g., from an advertiser.com web server 206 via a DNS server 208, both the content associated with the advertiser website 200 and, based on ad pixel tag 202, an ad call including instructions, or code, for receiving an ad network cookie.

(22) Thus, in addition to receiving the advertiser website content and an ad call, the user device 204 may also receive an ad network cookie, by executing the ad call received from the advertiser web server 206. Specifically, a web browser or mobile browser stored on user device 204 may execute the ad call received from advertiser website server 206, causing the browser to request a subdomain (e.g., “adnetwork.advertiser.com”) associated with the advertiser (e.g., “advertiser.com”). Because the advertiser may have previously updated a DNS record to redirect requests for the subdomain to an ad network (i.e., in a first stage, as discussed above), user device 204 may then direct an ad request, per the received ad call, to an ad network pixel server 210, via a DNS server 212 that executes the redirect. The user device 204 may then receive an ad network cookie from the ad network pixel server 210. As will be discussed in more detail, even if a browser associated with user device 204 is configured to accept only first party cookies, user device 204 may receive an ad network cookie from an ad network server, due to the DNS redirect, and because the ad call and cookie share a subdomain (e.g., “adnetwork.advertiser.com”) of the advertiser domain (“advertiser.com”).

(23) Having set an ad network cookie on user device 204 (i.e., in a second stage), FIG. 3 now describes a method for later accessing such first party cookies (i.e., in a third stage, as described above) and performing targeted electronic advertising, according to an exemplary embodiment of the present disclosure. Specifically, user device 204 may, at a later time (i.e., after visiting the advertiser website 200), visit a publisher website 300. Upon requesting publisher website 300, user device 204 may receive from a publisher.com web server 306, via DNS server 308, both publisher.com web content and an ad call.

(24) A web browser or mobile browser stored on user device 204 may execute the ad call received from publisher website server 306, causing the browser to request a subdomain (e.g., “adnetwork.advertiser.com”) associated with the advertiser and matching a cookie domain set above in the second stage. Specifically, the user device 204 may execute code that requests the subdomain from ad network pixel server 310, via a DNS server 312. If the user device 204 contains a cookie having a subdomain matching the requested subdomain (e.g., “adnetwork.advertiser.com”), then the ad network pixel server 310 may send the user device 204 a pixel image, thereby granting the ad network pixel server 310 access to the stored cookie of that subdomain. If the user device 204 does not contain a cookie having a subdomain matching the requested subdomain, then the ad network pixel server 310 may send the user device 204 a broken image.

(25) Having granted access to cookie data associated with the subdomain, user device 204 may now request a targeted ad from ad network ad server 314. Ad network ad server 314 may analyze the received cookie data and identify an ad targeted to user device 204, based on the analyzed cookie data. Ad network ad server 314 may then either send the identified targeted ad to user device 204, or send user device 204 instructions to receive the identified targeted ad. As will be discussed in more detail, even if a browser associated with user device 204 is configured to accept only first party cookies, user device 204 may grant access to an ad network cookie to an ad network server (one or both of ad network pixel server 310 and ad network ad server 314), because the ad call and cookie share a subdomain (e.g., “adnetwork.advertiser.com”) of the advertiser domain (“advertiser.com”). Furthermore, even if the browser of user device 204 is configured to accept only first party cookies, ad network ad server may still generate and send user device 204 targeted ads based on data stored in the cookie sharing the subdomain.

(26) FIGS. 4 and 5 depict exemplary embodiments of steps for performing the methods of FIGS. 2 and 3, respectively. Specifically, FIG. 4 is a flow diagram of a method for setting first party cookies on a user browser 400, according to an exemplary embodiment of the present disclosure. FIG. 5 is a flow diagram of a method for accessing such first party cookies on a user browser 400, and performing targeted electronic advertising, according to an exemplary embodiment of the present disclosure.

(27) As shown in FIG. 4, in one embodiment, a method for setting first party cookies on a user browser 400 may include several steps of a user browser 400 interacting with an advertiser (e.g., “advertiser.com”) web server 402 (step 4a), a DNS server 404 (step 4b), and an ad network pixel server 406 (step 4c). First, as shown in step 4a, user browser 400 may send a URL request to advertiser web server 402. As discussed above, the advertiser may have included an ad network pixel tag on its web page containing, for example, the “adnetwork.advertiser.com” sub-domain as its source. Thus, advertiser web server 402 may send back to the user browser 400 both web content associated with the advertiser's website and an ad call associated with that subdomain. The ad call may include instructions to request an ad from a subdomain of the advertiser (e.g., “ads.advertiser.com” or “adnetwork.advertiser.com”, etc.).

(28) At step 4b, upon receiving the ad call, the user browser 400 may request the indicated subdomain from a DNS sever 404, which based on instructions from the advertiser (e.g., in the first stage) may redirect user browser 400 to an ad network pixel server 406. At step 4c, having been redirected to the ad network pixel server 406, user browser 400 may issue a server request, such as an image tag (e.g., pixel tag) or ad call, to ad network pixel server 406, which may set a leadback cookie on user browser 400. As shown in FIG. 4, the leadback cookie may share a subdomain (“ads.advertiser.com”) with that of the ad call, and the leadback cookie may be served from the ad network pixel server 406 even though the ad call and cookie subdomain (“ads.advertiser.com”) is a subdomain of the advertiser domain (“advertiser”), and not the ad network.

(29) As discussed above, having set an ad network cookie on user browser 400 (i.e., in a second stage), FIG. 5 now describes a method for accessing such first party cookies (i.e., in a third stage, as described above) and performing targeted electronic advertising, according to an exemplary embodiment of the present disclosure. As shown in FIG. 5, in one embodiment, a method for accessing first party cookies on a user browser 400, and performing targeted electronic advertising may include several steps of a user browser 400 interacting with a publisher web server 502 (step 5a), a DNS server 504 (step 5b), an ad network pixel server 506 (step 5c), and an ad network ad server 508 (step 5d).

(30) As shown in FIG. 5, in step 5a, user browser 400 may be pointed to a publisher (e.g., “publisher.com”) web server 502. The publisher web server 502 may send to user browser 400 both web content associated with the publisher website and an ad call. In one embodiment, the received ad call may be a “universal ad call” disseminated to multiple publishers within a network of the ad network. In one embodiment, the ad call may include a segment of, e.g., JavaScript code that initiates several operations, including checking for JavaScript accessibility, checking whether cookies are turned on, making decisions based on HTTP metadata, and writing the ad call code (image tag equivalent). The code in the received ad call may also be configured to load up the domains, cycle through them, and make an image SRC call.

(31) In step 5b, user browser 400 may execute code in the updated universal ad call to perform a server call under each subdomain generated in the first stage, such as through a plurality of pixel calls, each of which checks a generated subdomain. Specifically, execution of code in the updated universal ad call may cause user browser 400 to cycle through one or more server calls, each server call being associated with a subdomain of an advertiser participating in a method of targeting based on first party cookies, e.g., via the second stage, or the method of FIG. 4. In one embodiment, the user browser 400 may cycle through the domains, e.g., using “for loop” logic. When embedding URLs or code that makes URL calls, HTML may, based on an associated IMG tag, retrieve content from any URL stored in a corresponding SRC element. Thus, for example, the user browser 400 may call each of “ads.advx.com,” “ads.advy.com,” “ads.advz.com,” etc. where “ads” is a subdomain associated with the ad network, and the method involves advertisers with domains “advx.com,” “advy.com,” and “advz.com.”

(32) However, as shown in step 5b, because each advertiser associated with the exemplary method may have updated its respective DNS record to redirect to an ad network server, a DNS sever 504 may redirect ad calls from user browser 400 to an ad network pixel server.

(33) Thus, as shown in step 5c, user browser 400 may redirect server calls for, e.g., “ads.advx.com,” “ads.advy.com,” “ads.advz.com,” and so on, to ad network pixel server 506. In one embodiment, the ad call received from the publisher web server 502 in step 5a may initiate code that checks for each advertiser's cookie, and stores all cookie matches for passing along to an ad network ad server. As shown in step 5c, ad network pixel server 506 may then return either a pixel image and cookie data or a broken image to the user browser 400. As discussed above with respect to FIG. 5, if the user browser 400 stores a cookie having a subdomain matching the requested subdomain (e.g., “adnetwork.advertiser.com”), then the ad network pixel server 506 may send the user browser 400 a pixel image, thereby granting the ad network pixel server 506 access to the stored cookie of that subdomain. If the user browser 400 does not contain a cookie having a subdomain matching the requested subdomain, then the ad network pixel server 506 may send the user browser 400 a broken image.

(34) In one illustrative embodiment, a user may have visited, for example, five advertiser websites that contain ad pixel tags set according to the second stage (e.g., FIGS. 2 and 4), and therefore have stored five cookies, each under a different subdomain. Because the user browser 400 interprets the ad call as a request to view the website of the subdomain, the browser may enable access to the cookie stored for the domain, and the ad network server and/or ad pixel server may obtain access to the contained cookie data.

(35) Since the ad network server and/or ad network pixel server 506 may now have access to cookie data of user browser 400, ad network 114 (FIG. 1) and its components may also have access to that data. The network pixel server 506 or ad network ad server 508 may read the cookie to see if it exists. For example, executed code, such as JavaScript code, may read and store the cookie data locally on the browser 400 and then send that data to one of the ad or network servers. Thus, as shown in step 5d, user browser 400 may issue an ad request to ad network ad server 508. The request may include or grant access to cookie data associated with one of the requested subdomains, or alternatively, the ad network ad server 508 may have already received or accessed that cookie data. It should be appreciated that the cookie data may include any data commonly stored in a cookie, such as user ID information, browsing history, purchasing history, user profile information, demographic information, shopping cart history, click history, impression history, predictions of user interests, and so on. Based on data stored in one or more accessed cookies, ad network ad server 508 may then identify or generate an electronic advertisement targeted to the user associated with user browser 400.

(36) It should also be appreciated that such accessed cookie data may be used for many other purposes other than targeted advertisements, such as frequency capping, saving state for purposes of maintaining log-in information, shopping carts, etc., or any other online function typically facilitated by third party cookies. Publisher impressions may also be segmented by different subject matter, for predicting, optimizing, and targeting advertisements based on groups of users that correspond to those publisher subject matter.

(37) Referring now to FIGS. 6A and 6B, exemplary methods for setting and accessing first party cookies will now be described with respect to steps performed by certain entities, including a user, advertiser, publisher, and ad network. FIG. 6A is a flow diagram of a method for setting first party cookies for targeting electronic advertising, according to an exemplary embodiment of the present disclosure. As shown in FIG. 6A, an exemplary method may include a user requesting to view an advertiser's web page (step 602), such as through a URL request, by pointing a browser such as user browser 400 to the advertiser's domain. The advertiser may, in response the user's request, send the user both web content associated with the advertiser's domain, and an ad call (step 604). For example, an ad tag may initialize an ad call or a pixel call. As discussed above with respect to FIGS. 2 and 4, the ad call may be associated with a subdomain that resolves to an ad network server associated with the advertiser. In response to receiving the ad call from the advertiser, the user may request an ad from the ad network (step 606). In response to receiving the ad request from the user, the ad network may send the user a leadback cookie matching a domain of the advertiser (step 608). Specifically, as discussed above, even if the user's browser is configured to accept only first party cookies, the user may receive an ad network cookie from the ad network, due to the advertiser's DNS subdomain redirect, and because the ad call and cookie share a subdomain (e.g., “adnetwork.advertiser.com”) of the advertiser domain (e.g., “advertiser.com”).

(38) FIG. 6B is a flow diagram of a method for accessing first party cookies set according to the method of FIG. 6A, and performing targeted electronic advertising, according to an exemplary embodiment of the present disclosure. As shown in FIG. 6B, at another time after the method of FIG. 6A was performed, the same user may request the web page of a publisher, where the web page contains an ad network pixel tag, as discussed above with respect to FIGS. 3 and 5 (step 652). In response to the user's request, the publisher may send the user both the web content associated with the publisher's web page and an ad call (step 654). Specifically, as discussed above, the ad call may be a universal ad call containing code that, when executed, initiates server calls to a plurality of advertiser subdomains generated according to the methods of FIGS. 2 and 4. In response to receiving such an ad call, the user may request the one or more subdomains of participating advertisers (i.e., those having subdomains associated with the ad network) (step 656). Because the advertisers associated with those subdomains may have updated respective DNS records to redirect to one or more ad network servers, the ad network may, upon receiving requests for those subdomains, check for a cookie associated with each advertiser subdomain (step 658).

(39) Specifically, as described above with respect to FIGS. 3 and 5, the ad network may then return either a pixel image and cookie data, or a broken image, to the user (step 660). As discussed above with respect to FIG. 5, if the user's browser stores a cookie having a subdomain matching the requested subdomain (e.g., “adnetwork.advertiser.com”), then the ad network may send the user a pixel image, thereby granting the ad network access to the stored cookie of that subdomain. If the user does not contain a cookie having a subdomain matching the requested subdomain, then the ad network may send the user a broken image. Thus, the ad network may be granted access to cookie data associated with advertiser subdomains.

(40) As shown in FIG. 6B, the user may then send an ad request to the ad network, based on any stored domains or accessed cookie data (step 662). For example, in one embodiment, based on the ad call received from the publisher, the user's browser may request a targeted ad from the ad network. Because the ad network has been granted access to cookie data associated with advertiser subdomains, the ad network may identify or generate a targeted ad based on one or more of the stored advertiser domains and cookie data (step 664), which were obtained as discussed above. Finally, the ad network may send the user the identified targeted ad, or send the user instructions to receive the identified targeted ad (step 666). Thus, even if the user's browser is configured to accept only first party cookies, the user's browser may grant the ad network access to an ad network cookie, because the ad call and cookie share a subdomain of the advertiser domain. Furthermore, even if the user's browser is configured to accept only first party cookies, the ad network may still generate and send the user targeted ads based on data stored in the cookie sharing the subdomain.

(41) As described above, the presently disclosed systems and methods may facilitate functionality typically associated with third party cookies even in a first party cookie environment. Specifically, even though an ad network server may set first party cookies on a user's device, such a cookie may be set according to an ad tag set by the website visited by the user, and therefore satisfy the user's cookie permissions, and the browser's cookie settings. Likewise, even though the ad network may access such first party cookies having the advertiser subdomain, access to those cookies may be enabled by execution of an ad call served from an ad tag of a website visited by the user, and again therefore satisfy the user's cookie permissions, and the browser's cookie settings.

(42) Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
