Glossary
RPM against CPM
RPM is what you earn per thousand views. CPM is what advertisers pay per thousand ad impressions. Why CPM is always the bigger number.
What are active users?
DAU, WAU and MAU are de-duplicated counts, which is why weekly is never the sum of seven dailies. What active means, and who decides.
What is ARR?
Annual recurring revenue is MRR times twelve, and nothing else. What it is useful for, and the three ways people quietly inflate it.
What is average order value?
AOV is sales divided by orders, and almost every chart of it is computed wrongly. Why the headline is not the average of the points.
What is bounce rate?
A bounce is a single-page visit, which means bounce rate cannot see time. Why high is often fine, and why GA4's definition is different.
What is churn rate?
Churn is the customers or revenue you lose in a period. Why the denominator is the whole argument, and how voluntary and involuntary churn differ.
What is click-through rate?
CTR is clicks divided by impressions. Why a falling CTR is often good news, and why it must never be read without volume beside it.
What is MRR?
Monthly recurring revenue, what it includes, how to normalise annual and weekly plans, and why two correct MRR figures can disagree.
Questions
- What is in the Notch Metrics content library?
- Three kinds of page: roundups comparing the tools in this category, alternatives to the better-known ones, and a glossary defining the numbers a founder tracks, such as MRR, churn and average order value.
- How is the library different from the blog?
- The blog is how-tos you follow, step by step, usually against a provider's API. The library is reference: you arrive from a search, get the definition or the comparison, and leave. Keeping them apart stops a definition competing with the guide that uses it.
- Are the prices in the comparisons current?
- Every comparison carries the date its prices were read off each vendor's own pricing page. Prices move, so check the date at the top of the table before quoting a figure from it.
