1,500 Mechanical Turk workers were instructed to:
- search for [money term]
- search for [money term, test site brand]
- click on [test site]

I wanted to see if a follow-up search and high CTR had any impact on Google Suggest and rankings.

While we did notice a spike in clicks and impressions, Google Suggest wasn't influenced in any way and neither were rankings.
A follow-up experiment could include a and consistent longer test period with more workers but it would cost a fair bit, so I'm parking this idea for now.
