Help Seddon define the correct measurements for two A/B testing experiments he'd like to run to:
* Drive some traffic to Wikivoyage
* Test a new mobile main page (vs. the old one)
We have some notes from Ellery when he worked with fundraising systems (Under Practical A/B testing at http://ewulczyn.github.io/projects/ ) which may become handy in this conversation.
Seddon would like to run the campaign before the end of June 2018 and do the analysis in July-September 2018.
