TL;DR: User cold start is a common challenge that businesses face when launching new products or services. It refers to the difficulty of gathering user data and making informed decisions without a pre-existing user base. This blog explores the effects of user cold start on business decisions, such as marketing strategies and product development.
Let’s start with an example:When a new subscriber joins Netflix- Netflix wants to recommend the relevant content. Yet, the recommendation system does not have access to the user’s historical data as none exists. To solve this problem, Netflix asks a series of questions through an initial survey to help determine a user's set of preferences. Then, Netflix recommends titles based on users with similar tastes. Once the user starts engaging with the content - Netflix leverages this data and gradually improves the user’s experience through better personalization.
That’s how Netflix handles with the cold start problem, but for most cases, and recommendation service, this solution is not feasible - as we don’t have the ability to survey the user and collect the crucial X amount of data points, to transition from a popularity based recommender into a personalized based recommender.
A cold start refers to a situation where a system or process has little to no information or historical data to work with when starting up or launching. In the context of business and user data, a cold start can occur when a new product or service is launched, and there is no pre-existing user base to gather data from.
There are three types of cold starts:
The answer is a definitive yes, particularly in the context of user data and product launches. Cold starts can make it challenging to gather user data and make informed decisions about marketing strategies, product development, and user engagement. This can lead to costly mistakes, inherent biases and missed opportunities for growth. However, with proper planning and strategies, businesses can overcome cold-start problems and successfully launch new products and services, for new and existing users, as one.
For example, the cold-start problem can make the promotion of new products a challenging issue. According to the collaborative filtering concept, the recommendation engine will always rate popular products higher than new products, regardless of a user’s interaction or preferences. Typically, products with higher visibility sell better than products that are hardly ever recommended. That leads to the situation of falling into a loop where the recommendation system promotes products that are already popular, and often those that do not suit the user.
Over the past two decades, businesses have been trained to believe that the third-party cookies (i.e., external data sources) — is the easiest and fastest way to gain access to customers’ personal information, and is the best way to get around the long-standing cold start problem. Unfortunately, this strategy has also opened up a new can of worms, resulting in customers who either feel spied on, due to hyper-personalized recommendations or who become frustrated by poor recommendations based only on very simple set of rules. In those cases, allowing third-party cookies to pull personal information is a sacrifice consumers have made for years, without fully understanding the repercussions.But things are changing. The power of the third-party cookies and mobile identities is in a rapid decline, thanks to constantly tightening consumer privacy laws. Facebook made headlines for its privacy protections that led to the Cambridge Analytica scandal, and Google has announced plans to phase out its own use of third-party cookies in Chrome by the end of 2024, joining Apple and others, who already opted out their third party cookies and identities.
A world without third-party cookies could exacerbate the cold start problem for businesses. With the phasing out of third-party cookies, businesses will need to find alternative ways to gather user data. This lack of meaningful personalization can have dire consequences when it comes to conversion rates and consequently to revenues. In fact, 91% of today’s consumers say they’re more likely to shop with brands that provide offers and recommendations that are relevant to them — but on average, 68% of visitors on a site are new users.
