I am first time posting my issue here, if it is in wrong forum then please guide me.
I have a niche blog. Usually I was getting around 100 visits daily from Google.
Now from 4th May 2013 onwards I have started getting 450+ visits from Google.
I haven't made any major change in my blog except I have set my Categories and tags as noindex around 2 weeks ago.
My blog is around two year old and I have changed it domain around 1 year back.
Some Analytics Details
All Traffic is coming from US
98% keywords are (Not Provided) so I am not able to find the keywords that may have get some good ranking in SERP.
All traffic is landing on my Home Page and then visiting 3-4 other pages.
Avg time per visit is arounf 30 sec.
Bounce Rate is 20%
I have tried to check the pattern using my AwStat (CPanel) and I didn't find any unusual activity.
All bots and IP addresses are same as in the month of April 2013.
I have tried to check the IP address from stacounter and it seems ok to me.
But I have an intention that it is fake traffic but I am not able to find more about it.
I have never submitted my site to any traffic exchange network.
Can anybody suggest what is happening with my traffic?
