I just try a new layout.
I have done also much load time optimzations.
I tested the results with a very slow internet connection.
The difference between the 2 versions had been amazing.
But I can see also the results in Google Analytics.
The average visit time decreased.
Maybe because the visitor sees faster, that this is not exactly what he searched.
So there are 2 reasons for a low average visti time
* The page is bad
* The page loads very fast
Any rumors about, that average visit time could have an influence on search results?
