A few years ago I introduced drop-down navigation on some of my sites. I wanted to move away from long columns of navigation links down the left side of my pages.
It has just dawned on me that all of my sites that have never performed well, or were hit by Penguin on April 24th last, have this drop down DHTML menu arrangement. Several other smaller sites with conventional html link navigation seem to performing much the same as they always have.
The numbers involved are waaaayy too small to claim there is a pattern here.... but I'd be very interested if anyone else has some experience/observations they would like to share.
