# Survey/marketing platforms

## Why use survey/experiment/marketing platforms?

* To test content in more depth than an A/B trial permits
* Better control over 'who is participating' and how much attention they are paying
* Things more towards 'basic background research'
* Closer to a 'representative sample'

## Some **p**articipant recruitment platforms

[Prolific  participant recruitment](https://globalimpact.gitbook.io/untitled/marketing-and-testing-opportunities-tools-tips/collecting-data-trial-outcomes/www.prolific.ac.uk): Created specifically for (academic research). Our impression is that this is among the highest quality panels, although there is some controversy over this.
