i checked the Google Analytics reports of my company and found out that at some days i get spammed from a traffic generating service.
I have no idea why? Maybe some agency we worked together "did that for us". I could filter out some of the wrong organic traffic by keyword use (in the keyword report i can see the url of the service). But on the same days the traffic ist still wrong because the service also generated direct traffic. Its from all the countries, languages is always set and they generate pages per visit (mostly 2) and an average sessions-duration (mostly beteween 7 and 10 seconds). I now will filter out bacause of these metrics. Do you have another idea how to solve this problem?
