Impressive, with product clicks increasing by 249%, transactions lifting by 51%, and revenue rising by 50%.

Targeting and personalization

Optimizely

A key feature facilitating this is Optimizely’s Adaptive Audiences. This feature can revolutionize personalization by blending rules-based targeting control with the scalability of automated personalization. It harnesses machine learning to segment users based on real-time behavior, providing a more tailored and responsive user experience. 

Moreover, your game of personalization can be taken to the next level with its built-in customer data platform aka Optimizely Data Platform (ODP). Why is it happening? We will clarify below.

Customer data platform 

Customer Data Platforms (CDPs) are integral to understanding and optimizing customer experiences. They collect, analyze, and activate customer data, enabling businesses to deliver personalized experiences.  

Optimizely 

Optimizely Data Platform (ODP) unifies segments and activates customer data in real time. It collects and enriches customer data from various sources, providing a comprehensive view of customer profiles. This data can be used to create and reuse segments based on behavior, preferences, and attributes, enabling more sophisticated and impactful tests. 

A strong point of this CDP is its diverse list of pre-built connectors, including Optimizely DXP, Shopify, Facebook, Google Ads, Google Tag Manager, and over 45 more.  

What makes this capability so special? If the system you're looking to integrate with lacks a pre-built connector, ODP offers tools to streamline the creation of custom integrations. This is particularly valuable for B2B manufacturers and distributors who need to link multiple data sources, such as ERP, CRM, accounting, and marketing automation platforms. 

AB Tasty 

On the other hand, AB Tasty does not have its own CDP. To have proper data management, it should be integrated with a third-party CDP such as Segment. These integrations allow AB Tasty to receive users' traits collected in Segment and use them to create segments within AB Tasty.  

VWO

Its Stats Accelerator feature allows for faster results by having the option to speed up getting to learnings, by allowing the system to send more traffic to one variant when more data is needed.

AB Tasty

AB Tasty relies on Bayesian stats which are magnets for high chances of making an incorrect decision. It encourages accepting findings with high rates of false positives.

VWO

SmartStats is VWO’s advanced, Bayesian-powered statistics engine for A/B testing, designed to provide intelligent results for smarter business decisions and reduce testing time by half. By calculating actual probabilities and clearly communicating uncertainties associated with statistical estimates, SmartStats aims to enhance decision-making.
