    What is your intended go live date and how long will the experiment run?

Jun 09, 2020 - Jul 07, 2020 (28 days)

    What is the main effect you are looking for and what data will you use to
    make these decisions?

If we see higher engagement with Hero Layout we will make it the default New Tab layout. Our primary success metrics will be (1) the % of each variant that engaged with Pocket recs at least once during the test and (2) the click rate on the 1st position Pocket rec. This latter metric is important, as it allows us to understand whether showing Syndicated content in the Hero position can send more traffic there.


Do you plan on surveying users at the end of the delivery?  No.
