Figure: Frosmo platform architecture and information flows at a glance

In a nutshell:

  • The Frosmo JavaScript library handles the modifications to the website, manages segmentation, collects usage data, and fetches content to display from the back end.
  • The Frosmo back end stores the usage data collected by the Frosmo JavaScript library and processes the data for reporting and analysis purposes. The back end also stores data related to modifications, segments, and other configurable resources.
  • The Frosmo Control Panel manages the Frosmo JavaScript library (and thereby how the website is modified and improved) and pools analytics data from the Frosmo back end.

The Frosmo platform is hosted on servers in Central Europe. However, Frosmo can also set up dedicated instances in specific market areas.

Frosmo JavaScript library

The Frosmo JavaScript library is the Frosmo presence in the front end. The library runs on top of a customer website site in the visitor's browser, integrating the site with the Frosmo Platform. The library provides both the framework for the Frosmo platform to operate on the site and Frosmo's custom solutions for improving the site. The library is platform-independent and can be used together with existing web application frameworks, such as Angular and React.

The Frosmo JavaScript library consists of two script files:

  • The Frosmo Core library implements the core front-end functionality and services of the Frosmo JavaScript solutionplatform. The library manages modifications and segmentation, collects usage data, and fetches modification content from the back end. The library is the same for all customers and sites.
  • The Frosmo custom script contains the configurations and custom code specific to a single site. These are used to modify the content and functionality of the site. The configurations include, for example, modifications whose content is preloaded, placements, segments, and triggers. The custom script runs on top of the Frosmo Core library and is unique to each site (or group of sites managed as a single site). Changes  Changes made to a site in the Frosmo Control Panel are automatically reflected in the custom script for that site.

The browser loads the Frosmo JavaScript library is loaded in the browser through two <script> elements placed directly in a web page's HTML source code, one for the . The first element loads Frosmo Core library and the other for second one loads the Frosmo custom script . Apart from adding these two elements, no other changes to the web page are required to use the Frosmo platformfor the site. The scripts are separated so that modifications can be pushed faster to your site without having to load the entire library every time. For more information , see about adding the scripts to a site, see Adding the Frosmo scripts to your site.

The Frosmo JavaScript library is optimized for fast loading. The Frosmo Core library is only 50 about 54 KB in size, while the Frosmo custom script usually ranges between 16-32 KB.

For more information about the Frosmo Platform and site performance, see Measuring and improving website performance.

Tip

The Frosmo JavaScript library is often referred to simply as the "Frosmo scripts". The Frosmo Core library typically goes by "Frosmo Core".

Script hosting and delivery

The Frosmo platform Platform uses content delivery networks (CDNs) to deliver the Frosmo JavaScript library and any Frosmo-specific media files used on websites. A CDN is a network of global servers connected to each other and used to store and deliver web content, such as images, videos, stylesheetsstyle sheets, and JavaScript files. When a visitor browses a site, the content of the site is delivered by the CDN server geographically closest to the visitor, decreasing page load timetimes.

By default, the Frosmo JavaScript library files are delivered through Amazon CloudFront, which serves the files using the CloudFront servers closest to the website visitor. Frosmo can also use other CDNs based on customer requirements.

The Frosmo platform Platform uploads the custom script and associated media files (ones added directly to modifications) to the CDN every time they need to be updated, that is, every time something on your the site is changed using the Control Panel. The assets files are always exported to CloudFront and, when needed, copied from CloudFront to other CDNs.

...

The data layer allows you to pass information data from a web page to the Frosmo JavaScript library. The library then sends the information that data to the Frosmo back end, where the data is stored in a database. The library can also use the information data directly in the browser to, for example, display content or manage segmentation.  The The exact behavior depends on how the Frosmo platform has been Platform is configured for your the site.

You can pass information data about the following events and items through the data layer:

Frosmo Control Panel

The Control Panel is the main Frosmo application for customizing and monitoring websites. In a nutshell, user interface of the Frosmo Platform. You use the Control Panel allows you to:

...

to customize your websites and monitor their performance.

The Control Panel is responsible for managing manages the Frosmo JavaScript library. Changes made to a site in the Control Panel are automatically reflected in the custom script for that site.

The Control Panel uses the Graniitti API to access the Frosmo back end , and to deploy the Frosmo custom script scripts to the CDN.

For more information about the Control Panel, see see Introduction to the Frosmo platform and User GuidesControl Panel and our user guides.

Graniitti API

The Graniitti API provides secure access to the data in the Frosmo back end. The  The API allows client applications to, for example, retrieve and create modification configurationsmodifications, and retrieve usage data collected by the Frosmo JavaScript library.The Graniitti API is currently only used by the Control Panel. However, in the future, the API will be made public. Customers can then Platform.

Customers can use the API to, for example:

  • Provide data to custom dashboards and management UIs.
  • Provide an outside access point to usage data that is collected and stored by the Frosmo platformPlatform.

The API uses token-based authentication for all requests.

For more information, see Graniitti API.

Message API

The Message API retrieves modification content to be displayed to visitors from the Frosmo back end. The , so that the content can be displayed in the browser. The Message API uses segmentation data and previous usage data to dynamically select suitable content for the visitor.

...

Optimizer API

The Optimizer API takes the data collected by receives and stores usage data from websites. In other words, the Frosmo JavaScript library and stores it in the Frosmo back end. The data is stored using a dedicated process, which ensures that no data is lost even if the website or the messaging component of the Frosmo JavaScript library becomes unavailablecollects usage data in the visitor's browser and sends the data to the back end by calling the Optimizer API. In the back end, the Optimizer API stores the data for further processing.

To secure the data during transit between the website site and the Frosmo back end, the Frosmo JavaScript library communicates with the Optimizer API over an HTTPS connection.

Custom APIs

A custom API is a customer-specific API created for a specific purpose that cannot be realized using the other APIs or the Frosmo JavaScript library. Frosmo creates custom APIs as needed.

Custom APIs are typically used to:

  • Return specialized data to the browser, such as data stored in a customer's back-end system or data read from a feed.
  • Send data to another service, such as email addresses to a mailing list for marketing automation purposes.

Modifications

...

Recommendations API

The Recommendations API retrieves recommendation data from the Frosmo back end. This data is generated by the Frosmo Recommendations subsystem and describes one or more recommended items, such as products.

Frosmo Recommendations generates recommendations based on usage data collected from a site and using an algorithm or filter that produces relevant results from that data. The generation process is driven by recommendation configurations, which define from what usage data the recommendations are generated, how exactly the recommendations are generated, and how frequently the platform should regenerate the recommendations. You define the recommendation configurations in the Control Panel, and then retrieve the generated recommendations for display by calling the Recommendations API from a modification.

For more information, see Feature: Recommendation and Recommendations API.

Frosmo Platform servers

The Frosmo Platform is hosted on multiple regional servers for improved availability. A customer's site is typically hosted on the server geographically closest to the majority of the site's visitors.

Frosmo has regional servers for:

  • Americas
  • Asia
  • Europe
  • Finland

Modifications

In the Frosmo context, a modification is a real-time change to a web page designed to personalize or otherwise improve the user experience of the website and to guide visitors to complete a conversion. For example, modifications can be used to improve the sales funnel of an ecommerce site, leading to an increased conversion rate. In technical terms, a modification is a managed piece of code that changes the content, appearance, or behavior of a web page directly in the visitor's browser. The code can consist of HTML, CSS, and JavaScript, in any combination. The purpose of a modification is to improve the user experience or usability of a website in some specific way. For example, modifications can be used to improve the sales funnel of an eCommerce site, leading to an increased conversion rate.

The Frosmo platform Platform can use the data stored in the browser's local storage and cookies, such as segmentation data, to determine which modifications to show to the visitor. Modifications can also use data stored in the Frosmo back end.

Here are some a few examples of common modifications:

  • Display personalized content based on the visitor's behavior or context.
  • Add new content, such as personalized product recommendations or content generated from data feeds.
  • Modify existing content, such as images or linksbanners.
  • Remove unnecessary content, such as distracting elements, site navigation elements in shopping carts, or surplus elements in mobile-optimized layouts.
  • Modify Test the layout and styling of and element or a web page.
  • Add custom JavaScript code that interacts with custom APIs.

Modifications are grouped into the following types:

  • Automatic modifications generate content automatically from a data feed or an API, or from existing content managed elsewhere on the website. The generated content is first stored in the Frosmo back end and then retrieved from there for display.
  • Basic modifications are used for content that is retrieved from the Frosmo back end and displayed only after the browser has rendered the web page.
  • Cached modifications are used for static content that must be inserted into the web page code before the page is rendered in the browser. (Like with all modifications, the content is maintained in the Frosmo back end, but unlike with the other modification types, the content is inserted in full in the Frosmo custom script for quick access.)
  • Recommendations generate content based on the visitor's previous behavior on the website.

Frosmo platform main cases:

  • A/B test: Create two or more content variations to test which variation performs best.
  • Multi-armed bandit: Select a multi-armed bandit algorithm that automatically decides the best-performing content variation and adjusts the variation distribution accordingly.
  • Personalization: Create a single piece of content that you can personalize.

Frosmo Platform administrators manage modifications in the Control Panel.

In terms of graphics and other media, Frosmo prefers to use the existing content on the site or content procured by the customer through their own CMS system. Customers deliver the content to Frosmo by providing us with access to their content management system (CMS). The Frosmo team then adds the content to the site using the Control Panel.

For information about how conversions are attributed to modifications, see Conversion attribution.

Data collection and storage

The Frosmo JavaScript library collects usage data in the visitor's browser and sends the data to the Frosmo back end over an HTTPS connection. The library sends the data in the background so as not to interfere with the visitor's user experience. The library also stores selected data locally in the browser.

The data can be categorized into:

  • Modification performance data
  • Product dataSegmentation data
  • Server logs
  • Visitor data

The Frosmo JavaScript library also stores selected data locally in the browser.

The data is mainly used for content targetingBy default, the Frosmo Platform collects and processes only anonymous and pseudonymous information about visitors and their behavior on a website. The platform does not collect data that in itself enables the identification of an individual data subject.

For more information about what specific data the Frosmo Platform collects and stores from websites, and how the platform processes and uses the data, see Data collection and processing.

For information about how Frosmo protects the data it collects, see see Data gathering protection and handlingprivacy.

Integration with external systems and services

The Frosmo platform Platform can integrate with customers' other back-end systems and other online services, such as analytics tools, marketing automation systems, and content management systemsdata management platforms (DMPs).

Integrations are typically used for synchronizing segmentation data between the Frosmo platform and a customer's Platform and an external back-end system, or for using the collected usage data outside the customer websitesite. Integrations also allow the Frosmo platform Platform to input data about displayed or clicked content directly into a web an analytics tool, such as Google Analytics.

You can integrate the Frosmo platform Platform with, for example:

  • Analytics tools: By default, the changes made on a site using Frosmo are not included in web analytics tracking. It is therefore important to integrate Frosmo to the analytics tools you use so . If you want to use a separate web analytics tool, you should integrate it with the Frosmo Platform, since changes made to your site with Frosmo are not, by default, included in 3rd-party web analytics tracking. Integration ensures that you have a clear understanding of what is happening on your site.
  • Marketing automation solutions: systems. The Frosmo platform can help you to make the most of it by effectively gathering data you Platform can gather and process segmentation and visitor data for marketing automation systems, which can then use the data to target your marketing efforts to the appropriate audienceaudiences. You can set up integrations with, for example, ad platforms and email services.
  • Data management platform (DMPs): platforms. As with many other systems, extracting useful data from DMPs can be laborious and requires the use of multiple APIs. The Frosmo platform Platform can be used as a master API, an interface for all data calls between your DMP and your website.

Here are some examples of common integrations:

  • Add visitor email addresses to specific mailing lists based on segmentation.
  • Use email notifications to provide shopping cart contents for interrupted shopping sessions ("abandoned carts").
  • Retrieve information from and store information to external databases. For example, retrieve user data from a customer's database and use the data to personalize website content, or send segmentation data to a customer's database.
  • Retrieve information from data feeds, such as product data feeds, or back-end systems, such as customer relationship management (CRM) systems. For example, retrieve information about new products or products currently on sale from a data feed, and generate corresponding product recommendations to visitors.

The Frosmo platform can also use segmentation data to identify target audiences for online advertising campaigns. The platform can integrate with the following ad servers:

  • Adform
  • Adtech
  • DoubleClick
  • Emediate
  • Google AdWords
  • KliKKi

Frosmo Platform security

The Frosmo Platform can limit user access to the Control Panel by IP address. This restricts means that users can access to the customer's dedicated Control Panel to Frosmo premises and to the IP addresses specified by the customeronly from the designated IP addresses and from Frosmo premises.

The Frosmo platform Platform can force all content that is provided through the Frosmo JavaScript library to the customer website a site to load resources only from specified domains. When this feature is enabled, the Frosmo platform Platform validates all modification content before it is saved to the Frosmo back end. If the content contains elements that could be used to load or inject resources from non-authorized domains, the content is rejected.

For more information, see Security overview.
