Yusp FAQ

What does personalization mean?

Personalization is a process that creates a relevant, individualized interaction between two parties designed to enhance the experience of the recipient. This process does not involve any consumer input besides the use of their purchasing or profile data. A perfect example is Amazon’s personalized recommendations that display as pop-ups showing suggestions of purchases that the consumers might like to make based on their previous purchase history.

What's a personalization engine?

Personalization engines are a type of information filtering system that can be applied on virtually any kind of website and help users find new content relevant to their interests – from music and events to products and dating profiles. Personalization engines are a useful alternative to search algorithms since they can guide visitors to items or content that they didn’t even know they were looking for. Product recommendation also allows for natural, logical upsell, and cross-sell opportunities.

What's the difference between traditional data analytics and machine learning-driven personalization?

At a high level, machine learning takes large amounts of data and generates useful insights that help the organization.

However, most organizations can benefit from traditional data analytics without more complex machine learning applications. One of the most important differences is that the data models typical of traditional data analytics are often static and limited in addressing fast-changing and unstructured data. When it comes to clickstream or IoT, it’s often necessary to identify correlations between dozens of inputs and external factors that are rapidly producing millions of data points. While traditional data analysis would need a model built on past data and a data scientist’s opinion to establish a relationship between the variables, machine learning starts with the outcome variables (e.g., CTR, eCPM/Revenue, cost/chat for the seller). It then automatically looks for predictor variables and their interactions.

In general, machine learning can create value when you know what you want, but you don’t know the important input variables to make that decision. You give the machine learning algorithm the goal(s), and then it “learns” which factors are important in achieving that goal from the data.

Besides, machine learning is also useful for accurately predicting future events. Whereas the data models built using traditional data analytics are static, machine learning algorithms continuously improve over time as more data is captured and assimilated. Machine learning algorithms can make predictions, see what happens, compare against their predictions, then adjust to become more accurate.

What's an A/B test?

A/B testing is a way to compare two versions of a single feature (e.g., variants of a webpage or an algorithm). Typically, the test is carried out by comparing the customers' response to variant A against variant B and determining which one of the two variants is more effective. Multivariate testing is an extension of A/B testing when more than two variants are tested.

Personalization engines run A/B and multivariate tests continuously to determine which variant is the most effective by using statistical models. The aim is to improve the recommendation to resonate more with the user and to achieve business goals.

A/B testing can also be used to compare two or more personalization engine vendors against each other to determine which one performs better. The vendor that performs better wins.

Does Yusp offer a demo?

We are happy to provide you a demo to showcase Yusp’s capabilities. Since Yusp provides specific personalization solutions tailored to our customers' needs, please contact us to organize a demo specific to your business.

What's Yusp's pricing model?

Yusp has a monthly fee proportional to the additional value it generates. The price also depends on the personalization modules that your business uses and the traffic size that Yusp needs to serve.

In certain implementation scenarios, there's also a one-time fee that covers our integration efforts. As the pricing depends on a couple of factors, first, we would like to understand your exact use case before we can provide you with exact pricing.

How does the Yusp personalization engine work?

Yusp generates recommendations similarly to how a human merchant recommends goods to his regular customer. Yusp knows which products and offers are the most relevant for the customers based on their taste, past purchases, current mood, new/fresh products, and their search context.

Besides, with the power of machine learning, Yusp can do it at scale, even for millions of customers at the same time. It goes beyond just considering the behavior of a single customer. It can also detect generic patterns in the behavior of a large number of customers.

What does the service fee include?

For example, how to differentiate between a support and a change request?

The monthly service fee includes:

  • the license fee,
  • the traffic fee until a reasonable limit (to cover our server and operation costs), and
  • a couple of technical support hours. 

If a request requires modification of the integration or the recommendation logic and can't fit into the agreed monthly support, it's handled as a change request and charged on top of the standard monthly fee.
