FIELD OF THE INVENTION

[0002]The present invention relates to computer browsing and, more particularly, to providing a web page based on user interaction.

BACKGROUND OF THE INVENTION

[0003]Networks, such as the Internet, have become an increasingly important part of our everyday lives. Millions of people now access the Internet on a daily basis to shop for goods and services and obtain information of interest.

[0004]The web is built on a very simple, but powerful premise. Much of the material on the web is formatted in a general, uniform format called HTML (Hypertext Markup Language) or the like, and all information requests and responses conform to a similarly standard protocol. When someone accesses a server on the Web, the user's Web browser will send an information request to a Web server. The Web server will respond to the request by transmitting the desired information to the user's computer. There, the user's browser will display the received information on the user's screen.

[0005]For example, suppose an individual wishes to purchase a printer via the Internet. The individual accesses the Internet and types in a vendor's uniform resource locator (URL). The individual may then access that vendor's home page to determine whether the vendor has the product that this individual wishes to purchase.

[0006]If the individual does not know which vendors sell printers, the individual may access a web site associated with a search engine. The individual enters the generic term “printer” into the search engine to attempt to locate a vendor that sells printers. Using a search engine in this manner to locate individual web sites that offer the desired product or service often results in a list of hundreds or even thousands of “hits,” where each hit may correspond to a web page that relates to the search term.

[0007]Once a user decides which web page to visit, the web page is formulated to interest the user. In particular, many web pages allow a user to customize the web pager so that each time the user visits the web page, the customized web page is presented to the user. One of the challenges of online interactions is providing customers or users with consistent online experience while using different channels such as website navigation, email, chat, bulletin boards, discussion forums, chat, and the like. For this uniform presentation, cookies are used.

[0008]Cookies are pieces of information generated by a web server and stored in the user's computer, for future access. Cookies are embedded in the http information flowing back and forth between the user's computer and the servers. Cookies allow user-side customization of web information. For example, cookies are used to personalize web search engines, to allow users to participate in WWW-wide contests, to store shopping lists of items a user has selected while browsing through a virtual shopping mall, and the like.

[0009]Essentially, cookies make use of user-specific information transmitted by the web server onto the user's computer so that the information might be available for later access by itself or other servers. Typically, the servers are part of the same domain. In most cases, not only does the storage of personal information into a cookie go unnoticed, so does access to it. Web servers automatically gain access to relevant cookies whenever the user establishes a connection to them, usually in the form of web requests.

[0010]There are many reasons a given site would wish to use cookies. These range from the ability to personalize information, help with on-line sales/services, or simply for the purposes of collecting demographic information. Cookies also provide programmers with a quick and convenient means of keeping site content fresh and relevant to the user's interests. The newest servers use cookies to help with back-end interaction as well, which can improve the utility of a site by being able to securely store any personal data that the user has shared with a site to help with quick logins, and the like.

[0011]Prior dynamically generated web sites, based on cookie customization, allow users and content providers to customize content. However, while these pages are dynamically generated based on a cookie, or hard coding scenarios in the web page or server. There is no flexibility to change the web page. Further, control of the web page is with the programmer, not a marketing group.

BRIEF SUMMARY OF THE INVENTION

[0012]The present invention provides a system and method to dynamically alter web pages based on a user's activity, marketing objectives, and predetermined conditions. There are two major modules in the disclosed system:

[0013]1. SmartBar™ tool; and

[0014]2. Business rule engine.

[0015]The first component is the SmartBar™ tool. The SmartBar™ is an online marketing tool that provides a point of reference on the web page for information and communication that is relevant to the specific viewer. In a preferred embodiment, the SmartBar™ is placed at the same location on each web page for a given site. A SmartBar™ or frame is provided containing at least one SmartBar™ cells. Each SmartBar™ cell is associated with a particular marketing objective. For the visitor on the site, it delivers a guided and personalized online experience with relevant and timely content. In one embodiment, Smart Bar™ modifies web pages to be viewed based in part on the items a user selects as well as the time a user spends on a specific page. Additionally, past browsing experiences can be considered. Smart Bar™ dynamically selects cell content for a web page and dynamically renders each cell, or selects cells, or alternatively, dynamically generates content for a web page. One goal of the Smart Bar™ is to enhance the browsing experience and minimize shopping cart abandonment.

[0016]The second component is the business rules engine that processes, in real-time, the events associated with each viewer and decides what business action is required. Business intelligence in the rules engine identifies what content is displayed in the SmartBar™.

[0017]In one embodiment, Smart Bar™ is used to develop marketing campaigns. Rules consist of conditions and their associated action or actions. Rules are preferably organized by campaign. Rules are used to determine what content should be displayed. The system can display promotional material, help icons, chat icons, sale items, other potentially interesting links based on activity, and the like. Each rule is assigned a priority. Thus, if more than one rule is triggered by a user's activity or browsing behavior, the rule priority determines which rule is triggered first and if other rules are subsequently triggered.

[0018]The business rules engine processes, in real-time, events associated with each visitor, and decides what rule is required. In one embodiment, the rules engine identifies whether a current visitor is a returning customer or a new customer and initiates the appropriate outcome or outcomes.

[0019]Each campaign can be broken down into segments. Each segment is adapted to deal with a specific event or type of user. This speeds the customization process and enables marketers to quickly develop campaigns.

[0020]SmartBar™ users can generate and save rules for use in other campaigns. In one embodiment, rules are stored in a database. These rules are then selected and customized, if necessary, for a campaign. The same rule can be used in multiple campaigns. Each campaign can be considered a container to group rules.

[0021]SmartBar™ enhances a web site visitor's satisfaction with a site layout and assists performance of a specific task. If a user's activity is indicative of a problem, a frame can be loaded with instructions detailing how to complete a task. Alternatively, a help icon or chat icon for customer service can be loaded. In this manner, a user's web site experience is enhanced. For example, if a user's activity indicates problems with checkout, a frame will appear to guide the user through the checkout process, thereby avoiding shopping cart abandonment and lost sales.

[0022]In one embodiment, SmartBar™ can deliver directed advertising in the form of services or products to a visitor. The advertising will change as the user navigates the web site. In one embodiment, content is presented to a user based on the visitor's browsing history.

[0023]The SmartBar™ provides a structure for managing multiple marketing messages in real time. The SmartBar™ enables the marketer to define SmartBar™ Cells, each cell dedicated to deliver different type of marketing messages. The SmartBar™ tool provides a user interface to configure content for the SmartBar™ cells. The SmartBar™ serves as a valuable medium to deliver targeted promotions, relevant content and proactive communications. Offering a combination of audience-specific navigation aids and relevant information, the SmartBar™ employs dynamically generated content that actively guides visitors through the site, so the marketer can truly replicate the in-store experience in an online environment. An improved user experience yields improved conversion rates, increase customer satisfaction, and promote brand loyalty by delivering an unmatched experience on the website. For example, in a typical SmartBar™, one cell may deliver product promotions, a second cell may deliver product comparison information, and a third cell may deliver a button for live-chat with the call center.

[0024]This intelligent and proactive technology tracks customer behavior to accurately identify and reach audience segments most likely to respond to personalized offers. SmartBar™ dynamically embeds content seamlessly into a webpage.

[0025]The combination of these two components allows for an effective handling of large volumes of interactions required in today's online environment. The disclosed system and method addresses the challenge presented to website managers who are interested in modifying, in real time, a current session of customers on the site.

DETAILED DESCRIPTION OF THE INVENTION

[0030]FIG. 1 depicts an embodiment of a system according to the present invention. As shown, a user 10 is connected to a web server 11 via the Internet. The user 10 has additional means of communication such as a telephone 50, fax machine, cell phone, hand held computer, and the like. In one embodiment, radio communication is implemented via radio tower 40. The web server 11 includes a database 22, which stores a plurality of web pages such as web page 20. In one embodiment, a second server 30 includes a module 32 for the application of business rules and dynamic web page generation or SmartBar™ cell population. In one embodiment, module 32 is part of server 30. In another embodiment, module 32 is part of web server 11. In another embodiment, module 32 is housed in another computer. Module 32 accesses data from database 34. Business rules are preferably stored in database 34. It should be noted that the functions of module 32 can be performed using separate modules.

[0031]There are at least three configurations for SmartBar™ system. In the first embodiment, the web site content and the SmartBar™ system are housed on a single server or linked servers. The user requests a web page containing SmartBar™ content and the web page and SmartBar™ content is provided by a single server. In the second embodiment, a first web server retrieves SmartBar™ content from a second server and provides the content to a user. In the third preferred embodiment, a user requests a web page containing SmartBar™ content from a server. The SmartBar™ content has scripts that retrieve content from a SmartBar™ server.

[0032]In operation, a user 10 requests a web page 20 from server 11. Web server 11 retrieves web page 20 from database 22. The web server, or other computer, in conjunction with server 30 and module 32, populates areas 21 in web page 20. Areas 21 are populated based in part on business rules. It should be noted that areas 21 are not fixed for every page but can vary in position and size depending on page layout. In another embodiment, areas 21 are overlays or pop-ups. In one embodiment, module 32 also hosts the content for areas 21. In another embodiment, database 22′ hosts the content for areas 21. Preferably, web page 20 includes embedded code that defines each area 21. These areas 21 are populated based on the embedded code, the user's activity, and the application of business rules. In a preferred embodiment, module 32 includes a business rules engine and a SmartBar™ tool. In another embodiment, the business rules engine and the SmartBar™ tool are separate modules.

[0033]The areas 21, the SmartBar™ frame, are populated using elements retrieved from a database based in part on business rules. Preferably, server 30, and more particularly database 34, provides pointers to database 22 where the content is stored. The SmartBar™ tool modifies the user's experience via such items as chat, pop-ups, displays, cell content, clickable images, and the like, modify the user experience. The code is embedded on the page 20 at the desired location 21 chosen by the marketer, web designer, alike, possibly using an include file statement. It should be noted that the system can preferably push additional items to overlay or populate a new window such as a pop-up or chat channel. Overlays float over a page and pop-ups are new windows. The code issues real-time request asking the server for dynamic content that best match this visitor at this time. Each of these request triggers a sequence of business rule evaluations that are associated with the particular web page. These business rules determine the actual content to be displayed in each of the cells 21. The way the cells 21 are displayed to the visitor is de-coupled from the cell definition and from the rules that determine the content of the cells. The component that controls the display, or look & feel, of the SmartBar™ cell 21 is the SmartBar™ Template. The user can define SmartBar™ templates in the Content Library. The template may contain any web-page code (e.g. HTML, DHTML, or ASP).

[0034]As shown in FIG. 2, the process begins when a user requests a web page. The system retrieves a web page format for the requested page. (Step 100). In one embodiment, the web page format is retrieved from database 90. The system then generates the web page including any SmartBar™ cells 21. (Step 110). The content of the SmartBar™ calls is determined based on user activity and business rules. If there has not yet been any user interaction, business rules and embedded code determine the content of SmartBar™ cells 21.

[0035]Once the web page 20 is generated, the user's activity on that page, and subsequently viewed pages, is monitored and evaluated. (Step 120). The user's activity includes time spent on a particular page, additional data requests, adding items to a cart, and the like. The system revises the web page being displayed (Step 130) based on the user's activity or alternatively generates a new page based on the activity (Step 110).

[0036]The business rule engine processes, in real-time, the events associated with each user and decides what action to take, if any. If the business rule engine determines a need, action is taken in real-time. If no immediate action has to be taken, a non-modified web page is displayed. Specific actions to take include special offers, invitations to chat, help icons, related products, related material, displaying pop-ups, clickable images, and the like.

[0037]The business rules engine uses rules that are based on conditions and actions taken while a user is visiting a specified website or series of web pages. Certain conditions will result in specific actions being taken. The conditions include both the activities that a user that performs while on a site and the user's behavior while on a page, and if available, the past activity, IP address, search activity, and the like. Rules provide a way to react to customer activity. Visitor rules also customize the processing of visitors and/or people communicating via chat or another channel. In a preferred embodiment, rules are created within a specific context that determines the circumstances in which the rule will apply. The rules respond to conditions that exist. Conditions specify which actions are triggered. If no conditions are specified, the rule is triggered in response to all activity. It should be noted that multiple conditions can be specified or Boolean logic can be used.

[0038]Each rule can control multiple cells, and multiple rules can affect a single cell. The rules control the displayed content. Under certain circumstances, a cell may not display any content. Marketers or others define the content of the cells. Web designers place calls for SmartBars™ and SmartBar™ cell content. The management of the page is done using a template. The template for a SmartBar™ is preferably stored in a content library, not on a web page.

[0039]Rules allow the web site to react to visitor activity on the website. Visitor Rules customize the processing of website visitors; they are used to create custom business rules that trigger related actions such as chat invitations, promotional offers, marketing campaigns, and the like. Rules are preferably created with a specific rule context or Rule Type that determines the circumstances in which the rule will apply. For example, a rule that is set for “when a visitor enters site” will be triggered for processing each time a visitor enters the site. When the user visits the site, the conditions specified by the rule will be checked and if found true, the actions specified in the rule will be performed by the system.

[0040]Conditions may include the type of page, section of a page or a specific URL. Additionally, if the user reaches a page via a hyperlink or by typing a URL, that scenario can be monitored without taking any action. The time a user spends on a specific page may also be a condition. For example, the system can monitor whether a user spends more or less than a specified time on a page or group of pages. Conditions relate to events that occur as well as events that do not occur. For example, adding items to a cart but not checking out.

[0041]Rule conditions can also apply to variables. Rule actions can set the value of a variable to a predetermined value. For example, the value or occurrence may be a shopping cart total greater than a specified dollar amount or contain more or less than a specified amount/quantity. Further, other variables can indicate a transaction error (a Boolean variable). The system can also monitor at least such items as an occurrence of a specified event, entering a communication channel such as chat before or after a selection, days since last chat interaction, and the like. Further, other variables can be a new visitor, old visitor, user's IP address, and the like.

[0042]As discussed above, when certain conditions occur, an action is triggered. Actions may contain sub-actions. In one embodiment, the actions are executed in a specific order. However, in another embodiment, the actions occur in random or non-specified order. A sample of actions based on rules and alerts are shown below in Table 2.

[0043]FIGS. 3A-3H depict a typical user's interaction on a series of web pages for a given web site. FIG. 3A depicts a single page for a web site, retail.com. As shown, the SmartBar™ cells 21A and 21B are on the right side of the page 100 in a SmartBar™ frame. As shown, the SmartBar™ frame includes cells 21A-21F. In this embodiment, cell 21A is a communication channel, cell 22B is a product recommendation cell, cell 21C is an incentive cell, cell 21D is an express checkout cell, cell 21E is a buying guide, and cell 21F is a post purchase cell. It should be noted that other cells could be part of a SmartBar™ frame. Other elements such as headings 22, links, images and the like can be added using SmartBar™ cells. While the SmartBar™ cells are shown together on a background. In one embodiment, they are space apart from one another. In another embodiment, the SmartBar™ cells blend into the page as uniform elements. The SmartBar™ cells as shown provide a user with means to initiate help via online chat or investigate specials. In a preferred embodiment, the SmartBar™ frame and all of its cells are on each page, however, only those cells that have had their content requested are displayed. If the user browsing page 100 clicks (selects) SmartBar™ cell 21B, the web page shown in FIG. 3B is generated.

[0044]As show in FIG. 3B, web page 102 includes SmartBar™ cells 21A, 121, and SmartBar™ 221. SmartBar™ 121 is an example of a single-cell SmarBar™. A web designer or marketer may include cell 21A on every web page for this site because it is a help button. SmartBar™ cells 221 and 121 are generated based on business rules and user activity. For example, SmartBar™ frame 221 displays various cameras and camcorders based on popularity. Additionally, it should be noted other information can be presented to the users such as shop by brand options and the like.

[0045]If the user selects the camera designated in SmartBar™ cell 121 the user is brought to a webpage 104 depicted in FIG. 3C. As shown in FIG. 3C only SmartBar™ cell 21A is present. Depending on the web design other SmartBar™ cells can be displayed. When the user adds the items shown in FIG. 3C to a shopping cart, a new web page 106 is displayed as well as other options in the SmartBar™ cells. As shown in FIG. 3D, other sales and marketing SmartBar™ cells can be added to the shopping cart page such as a free shipping incentive (21C) and instruction for purchasing on the website (21E). It should be noted that the free shipping or other element can be determined based on the purchase price or value of items in the visitors shopping cart.

[0046]When the user selects the SmartBar™ cell 21C designating the free shipping a new screen is generated as shown in FIG. 3E. Here, the SmartBar™ cell can include other items such as other products manufactured by the same manufacturer 21B or an express checkout button 21D. Further, the item being featured in the center frame can also be managed as a dynamic-content SmartBar™ cell. It should be noted that cell 21B changes its content based on conditions present during user interaction. Based on the business rules used to generate the web pages, if the user selects the Sony item in cell 21B a new screen 110 as shown in FIG. 3F is generated. As shown, this screen 110 can include a SmartBar™ cell offering a discount if the user adds the current item to the cart. It should be noted that while a discount is shown in FIG. 3F as SmartBar™ cell 21D any offer can be implemented or information presented using SmartBar™ cells.

[0047]As shown in FIG. 3G, once the second item is added to the shopping cart a new basket screen is generated. This new screen reflects the discount offer. It should be noted that because the visitor already qualified for the free-shipping offer shown to the user previously, this incentive is no longer generated. Once the user checks out, she is provided with a receipt page (FIG. 3H). On this page, because the order is complete, the user is provided with an opportunity to request a catalogue (cell 21F). It should be noted that other offers can be provided to the user at any time and/or inst at any point on the screen.

[0048]In the preferred embodiment, the SmartBar™ code on the page requests its content to be rendered with respect to a specified template. The template is stored in the Content Library. This template is configured and customized by the user. Generic templates are also provided with the software.

[0049]In another embodiment, the code for rendering the SmartBar™ is embedded on the web page, requesting in real-time the content to be resolved through the business rules engine. As shown below, the SmartBar™ code establishes cells on a web page. The code below includes programmed content calls. Alternatively, the code includes calls to other content. These cells are then using the business rules as discussed above. It should be noted that the placement of the cells is at the programmer's discretion for the preferred presentation and that the business rules are designed for specific marketing purposes, informational services, and the like.

[0050]SmartBar™ cells are dynamic cells embedded in web pages. In a preferred embodiment, the HTML code embedded in the web page pulls information from a dedicated web server.

[0051]FIG. 4A depicts one embodiment of the content library used to generate SmartBar™ cell content. The user can select from clickable images, links, pop-ups, and SmartBar™ templates and the like. In a preferred embodiment, the user can create and modify content. The “create new” button generates a screen such as the one shown in FIG. 4B.

[0052]FIG. 4B is a template editor. A user can name and describe a template and link the template to various promotions. Further, the template provides an area whereby HTML code is entered to generate the cells.

[0053]As shown in FIG. 4C, a clickable image is defined. The marketer enters the name, description, resource type URL, destination URL. In a preferred embodiment, the user enters the height and width of the clickable content on this screen. Further, once the template is established, rules are associated with the specific SmartBar™.

[0054]FIG. 4D shows various rule types that will trigger a SmartBar™ template and the rule priorities within each type. Rule types include clicking a dynamic button, entering a page, entering a site, click-to-chat, leaving a site, browsing a site, and the like. Each of these rule types can designate a specific activity or group of activities. Additionally, other pop-ups or content is displayed based on rules and user activity as discussed above.

[0055]In one embodiment, rules can be organized under campaigns (FIG. 4E). Campaigns can be setup for a specific period of time.

[0056]It should be noted that in another embodiment, a user first establishes rules, then groups these rules into campaigns. After the rules and campaigns are established, SmartBar™ templates are generated to support the campaigns. Further, because the generation of the SmartBar™ cells, the business rules, and the web layout are discreet activities, no specific order is required for the overall implementation. In a preferred embodiment, a user defines a campaign. Rules are then written or selected to accomplish the campaign.
