wizard- very interesting scenario- two identical sites-different languages. It appears like the site with much less competition (2.7 million results) popped out pretty fast. The other (25 million results) is in a really competitive area and is taking much longer.
It seems , based on this perfect scenario, that there must be a percentage of time based on competitiveness of terms for the filters to be removed.
Wizard- when the three month site popped out- was it during or after an update? Do you remember anything outstanding at the time of it's appearance? Did one achieve pr before the other?
