Account Penetration is a measurement of the extent to which your products or services are used within a particular customer account.

Activation Rate

Activation rate refers to the percentage of users who have completed a desired action or engaged with a product or service in a way that indicates they are fully using it. This metric is often used in digital marketing to measure the effectiveness of a campaign or product launch. A high activation rate implies that a large percentage of users are actively engaging with the product or service, which can lead to increased revenue and customer satisfaction. For example, if a new app has 10,000 downloads but only 5,000 users have actually created an account and started using it, the activation rate would be 50%. By measuring activation rate, companies can identify areas of improvement and optimize their marketing strategies to increase engagement and retention.

Active users are engaged users who have used a specific product at least once within the last 30 days, or some other duration of time set by your organization. By tracking Active Users, marketers and product managers can proxy the popularity and effectiveness of their product, identify areas for improvement or expansion, and even upsell to more committed users. For more advanced organizations, it's common to avoid measuring Active Users just by login frequency—marketers should also consider in-product actions and interactions that showcase real value generation for these users. Keeping an eye on Active Users helps companies ensure their products remain relevant and useful.

Beta Testing

Beta testing is the process of testing a software, application, or product before its official launch to identify and fix any errors or bugs that may have been missed during the development process. It involves releasing the product to a limited number of users who try it out and provide feedback on its performance, usability, and overall user experience. The feedback received during beta testing helps developers improve the product and ensure that it meets the needs and expectations of its target audience. Beta testing is a crucial phase in the product development cycle, as it helps ensure that the final product is of the highest quality.

Botton-Up Adoption

Bottom-up adoption is a process in which a new technology, product or service is adopted by individuals or small groups within an organization, rather than being imposed from the top-down by management or executives. This approach is often considered more organic and allows for greater individual autonomy and creativity. For example, if a company wants to introduce a new project management tool, instead of mandating its use from the top, they might allow individual teams to test and adopt the tool on their own. This way, the tool can be evaluated on a smaller scale before it is fully implemented across the organization. Bottom-up adoption can also help build buy-in and enthusiasm for the new technology or process.

As a popular sales tactic, over 40% of companies see 11–30% of their revenue coming from cross-sells.

Customer Effort Score (CES)

The Customer Effort Score (CES) is a metric that measures how easy or difficult it is for customers to interact with a company while resolving an issue or completing a task. It is a customer satisfaction metric that gauges the level of effort customers had to put in while engaging with a company. CES is measured by asking customers a simple question: "How easy was it to solve your problem with our company?" and then customers can rate their experience on a scale from one to five (or ten). For instance, if a customer service experience is smooth and effortless, the CES score would be high, indicating high customer satisfaction. On the other hand, if the customer had to put in a lot of effort and experienced frustration, the CES score would be low, indicating poor customer satisfaction.

It is a method of assigning credit to multiple marketing channels or touchpoints that have influenced a customer's decision to buy a product or service. Unlike traditional single-touch attribution models, which give credit only to the last touchpoint before conversion, multi-touch attribution models consider every touchpoint along the customer journey, providing a more comprehensive understanding of the customer's behavior.

Net Promoter Score (NPS)

Net Promoter Score (NPS) is a metric used to gauge the loyalty and satisfaction of customers towards a brand or company. It is based on a single question survey that asks customers how likely they are to recommend the product or service to others on a scale of 0 to 10. Those who respond with a score of 9 or 10 are considered promoters, while those who score 7 or 8 are passive, and those who score 0 to 6 are detractors.

CRR is calculated by taking the number of customers at the end of a period (minus any new customers acquired during that period) and dividing it by the number of customers at the start of the period, then multiplying by 100. For instance, if a business starts the month with 100 customers, gains 20 new ones, and ends with 110 customers, the CRR would be 90%.

Churn Analysis

Churn Analysis is used to identify the rate at which customers stop doing business with a company over a given period, and the reasons behind their departure.
