Volument - A new take on website analytics

volument.com

Author here: the title might seem like a clickbait, but we've seen it's accurate. Another option is "harmful". Correct answer is that it depends depending on how the testing tool is used:

1. If used correctly -> "harmful" (months of waiting without touching the site)

2. If not (like in most cases) -> "bullshit" (results are random)

The major difference between traditional A/B testing and Volument is that the comparisons are based on _cohort analysis_. It takes two groups of visitors and places them side-by-side starting from the very first visit: how they gradually build awareness and interest (metrics from the first visit) before taking action (on the first visit or on later visits). Then you take a cutoff day (say Day 7) and compare what has happened (how much retention, conversions, sales, virality) before that day. The whole "traction" so to speak.

This one is significantly more active than the others.

Can you give few examples of those other companies? Thanks.

It used to be like that, but that's no longer happening. Last winter, there was no snow in Helsinki at all :(

ePrivacy talks about "information stored in the terminal equipment", which includes any information you can get from the device. For example the user agent, location, and operating system. It's not about the information itself being essential or not, but what you do with it: is it for essential purposes (consent not needed) or non-essential purposes (consent needed).
