From observation, I would say that these types of pop-ups typically appear above the active item. However, you need to make your decision based on the design of the rest of your page. Where do you have the most room for it? The goal should be not to have it fall outside of the current window boundaries and not to cover up the active item or anything of importance. Which placement will most likely meet these goals? Also, what are the dimensions of the pop-up? Is it wider than it is tall or vice versa? Placement of the stem would then be based on the placement of the pop-up.


2. Are there any best practices around delay? (Are there any similarities to
the 250ms menu delay?)

It should be long enough that it won't pop up when the cursor is moving across the screen, but short enough that it is likely to show before the user clicks on the link.


3. Are there any best practices on making the layer actionable versus
informational? (with links and a close button versus text only and closing
on mouse-off?)

Both are valid. It depends on what the purpose of your pop-ups are. As far as closing on mouse-off vs. an explicit close, I base the decision on the amount of content. If there is actionable content, an explicit close is preferable. If there is a significant amount of content, an explicit close is preferable so you don't have to worry about leaving the mouse stationary to read it. Short amounts of content will do fine with an automatic close.


Best,
Jack

The details are not the details.
They make the design.
