Example of email Ranking Model
personalization email content
1. As the section position increases the Uctr drops.
2. As the section size increases the Uctr drops.
3. Top position is important
1. First link is very important, since it actually contains
more than 50% of all the clicks.
2. The section order that we have now is not optimal.
3. On the Mobile data, the click distribution for the first
position is higher than the Desktop data, but the click
distribution on mobile drops faster than the desktop data
from the first position to the second position.
