How do I prevent invalid clicks?

On some rare days, I notice an unusually high CTR on my blog...

I think sometimes those clicks r invalid....done by someone for whatver reason I dont kno!

Is there any way I can prevent such invalid clicks?

 

Keep sending them emails whenever you suspect unusual activity on your blog.
Google will understand and will not ban your account.
This is one of the best way to prevent your account being sabotaged.

 

Try using Adlogger or someother Adsense tracker

 

I have already emailed them once..and I suspect sending too many emails will only make them suspicious towards me.

I think having a prevention software installed is better!

 

Yes indeed, One of my friend was also banned for sending lots of emails to them...

 

Oh my God....

We all gotta be reallly careful about the TOS...n also how to handle difficult situations.....

 

If I've inadvertently clicked on one of my own ads, or have noticed suspicious clicks (like 30 from same IP in China) I've always contacted Google about it.
They've always replied and thanked me for bringing it to their attention. I think there's a lot of unnecessary paranoia out there about what Google does and does not do.

 

well there is a paronia but its not unnecessary...especially for small publishers
