So, was the overlay more effective at conversions than no overlay at all?

I think this is a great article about how to measure overlay timing effectiveness, but didn't convince me that overlays work at all in general.

Yes, the overlay became more effective. Saw 4-5x increase in sign up rate in some cohorts. It certainly gave a much higher sign-up rate than without any overlay. In fact, just trying a dismissable overhead banner was also not working as great as an overlay.

Ahh that's interesting. Was the overlay un-dismissible?

[aj_ycombinator]

It was dismissible. The whole idea was not to take an approach where the content is locked down.
