How long does it take the Alexa ranking update? Every weeks or every months? Also if does not install alexa widget, will the rank update? Thanks
The widget, toolbar, and the like are not needed for an update. The rank seems to update at regular intervals, dependant upon the rank of the site. 80k-150k seem to update around once every three days. The lower the faster, the higher the slower... Just check it daily for a week and you'll find the trend.
