What does this change?
This PR adds an AB test, to match that introduced in this PR, that we'll use to test the impact of limiting the eligibility of rendering inline merchandising slots on articles.
We introduce the same AB test definition as on DCR, and use the
canRunfunction to only enable the test on page views for which an inline merchandising ad slot is eligible. These pages are defined by the rules on this dashboard page (private link), which is reproduced at the time of writing below:If we detect the pageview is in the variant of the test, then we override the value of
hasInlineMerchandiseand therefore never show such an ad, even on articles that would usually be considered eligible. If not in the test, or in the control, the behaviour will remain the same as previously.We'll be able to assess the impact of this change by measuring metrics in the usual way, in order to see what impact blocking the inline merchandise has on things like ad-ratio and revenue per 1000 pageviews. Also, we can set up a line item for the control group (using targeting we already supply as part of our page targeting object) that will collect statistics about interactions with the inline merchandise ad.
Screenshots
Note in the variant, where we block the inline merch slot from rendering, the
inline1ad appears much higher up the page.Why?
We'd like to measure the tradeoffs when running an inline merchandising campaign. Running such a campaign and displaying an inline merchandising advert has the effect of pushing subsequent inlines further down the article. This can have an impact on ad-ratio (as less impressions may be recorded if a reader doesn't reach further down the page), and therefore on revenue.
To assess the impact, we'll run an AB test where inline merchandising is disabled for eligible pageviews in the variant, with no change in the control.
