HELLO ALL!!!! well i wanted to ask that by getting clicks by different users and diferent Ip but at a same particular time is it a problem ?
No, you can have few hundred or thousand users online at same time, so there will be also clicks in same minute. This is no problem, as long as they are valid clicks and not fraud clicks.
This is not a prob as number of visitors present on site differ from time to time and so a number of clicks can come at same time . BUT ... dont try to cheat . They will catch you and you know the result .....
If you're afraid about invalid clicks, you may install and use this free software: http://www.adlogger.org/index.php/Main_Page
If you are worried about the pattern of clicks on your site, email the AdSense team. They may be able to confirm that everything is alright, and it at least solidifies your position as attempting to curb possible fraud.
