Ecommerce marketing technology stack: what earns a place
How are the tools rated?
Each tool carries one of three labels. They are our view, not a market fact, and we change them when our view changes.
Core
In our view, worth having in place for most brands.
Selective
Worth it under specific conditions. The entry says which.
Watching
Not recommended yet. We follow it.
A label is not a verdict on the vendor. It is a view on whether the tool is worth the effort for a brand of this size.
How is the index organised?
Measurement tools are rated like any other. A holdout test is one method for finding lift. Useful when it changes a decision. Wasteful when it cannot be read. Server-side tracking gets the same treatment: the rating depends on the problem it solves for you.
If your question is about the foundations, start with the ecommerce tracking audit. It is about the checks that change a budget decision.

How do we choose a tool?
Every tool on this index gets the same four tests. The rating is what is left when they are done.
Changes a decision
Does it change a budget decision? A dashboard that looks good and changes nothing is a cost.
Can be read
Can someone on your team open the output, understand it and say what to do next? If only the person who set it up can read it, it will stop being used.
Worth the effort
Count the build, the upkeep and the person who owns it, not only the licence. Then ask whether that effort is worth it for a brand of your size.
Fits your problem
The rating depends on the problem it solves for you. Each entry says when to skip it, and your account may be the exception.
Learn the words before someone uses them on you
Marketing has a lot of vocabulary. Some of it exists to win arguments. Start with the Glossary index (A–Z). Read incrementality for mid-size ecommerce brands if measurement is the worry. Comparing partners? See how to choose an ecommerce marketing agency.
FAQ

What do Core, Selective and Watching mean?
They are our labels, not an industry scale. Core: in our view, most brands in our segment need it. Selective: it depends on your situation. Watching: we are not recommending it yet.
Does a Core rating mean I need the tool?
No. It is our view for the typical brand. The entry for each tool lists when not to use it, and your account may be the exception.
Will the ratings change?
Yes. They are our view, and views move. A rating that never changes is not a view.
