Hi, I daily submit 100 links on stumbleupon and i get maximum traffic from "California" . Why is it happening that most of the hits are coming from California ?
Yep, what content are you sharing? Are you targeting "California"? It's quite difficult to answer if we don't have the full query.
Are you targeted California as country? It may be the reason of your problem. On the other hand it also depends on server location. If your server location is California then you should change it. I hope it will help you to solve your problem.
It happens... Sometimes the content you are sharing becomes viral or popular among audience in specific geographic region. Some of your audience might have shared your content in their circle. This is how content sharing works. So, do not bother about it. But, if the traffic is very huge, it might be junk traffic (which is deliberately directed towards your website)... You better look into matter in that case.
Your keywords you are targeting are being related to the area of California. Articles themselves are targeting California. Other issues may be reasons why this is happening.
