Welcome to WebmasterWorld Guest from 18.104.22.168
It would be nice to introduce 150-200 new visitors to my site a day but what if 15-20 different people click on a ad from the same computer? Is this dangerous? Should I remove my adsense from the site during this time?
3 user accessing your blog dozens of times a day from the same IP without referrals (i.e. opening the page without having any link pointing to it..) . There might be a painful mis-judgement from Google!
If you don't want to remove adsense you might play with php or server-side includes and serve the adsense to all the world except the IP of the cafe.
I was last year several times in spain in an internet cafe.
Using Google, I recieved a strange error message. Something like searching Google is not possible from this IP address.
This year, I was on vacation in Italy. When I visited webmasterworld.com from the internet cafe, I received an error message, that I have to log in, because of abuse from this IP address.
Visiting an internt cafe is some sort of an emergeny action, because GPRS would cost me 15.-EUR per MB in Italy. Just to check my emails and my AdSense stats and upload the latest changes from my web sites.
There is NO WAY to prove that the ads are NOT clicked by the same person on that set of IPs.
The is a gray area, on the darker side actually. Call it Dark Gray...
I expect a good conversion when somebody searches, comes to a page about the search term with information and some ads about it.
What conversion should a random visitor from an internet cafe have?
Low CTR, low EPC because bad conversion and smart pricing. I would expect only 5% of the eCPM compared to visitors coming from a search engine.
Even with 10 visitors a day * 3 computers * 7 days, it's only 210 visitors total, and a site has to be really good to convert such random visitors to only $2.
So for nearly no money risk the AdSense accout?
