# Collecting outcome data

For a trial to yield insight, we need to be able to track and measure meaningful outcomes, and connect these to the particular 'arm' of the trial the person saw ... (if they saw any arm at all)

## Notes from conversations (need explanation)

\
In this section we discuss **how to see the&#x20;*****results*****&#x20;of your promotions and trials, and how to access data sets of these results that you can analyze.**<br>

* [Facebook ads interface](/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes/facebook-meta-ads-interface.md) and [Pivot tables](/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes/facebook-meta-ads-interface/pivot-tables.md)
* [Google A/B, optimize interface](/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes/google-a-b-optimize-analytics-interface.md) and [Google analytics interface](/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes/google-analytics-interface.md)

<summary>Aside notes on modes of testing and tracking</summary>

1. Tracking: See a page, track action afterwards
2. Putting ads on Youtube and testing click through
3. [Geographic segmentation](https://github.com/daaronr/eamt_gitbook_public/blob/main/methodological-discussion/experimental-design-methods-issues/splits-randomization-in-practice/geographic-segmentation-blocked-randomization.md): Targeting zip codes and looking at activity from zip codes…

Other approaches include time-series and difference in difference in response to switching on or off the ad, trial, or page content.\

Nick:  Branch and Amplitude/apply/segment ... to track someone throughout the whole funnel

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://globalimpact.gitbook.io/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
