May want to use Adlogger if you mean clicks on ads. A thread on the new version is @ http://forums.digitalpoint.com/showthread.php?t=219621
Some times adlogger report is wrong because it treat when some one move the mouse over the ads also as clicks. Other than that its very good.
A click is counted when the mouse is over the ads and the page exits. For example, a false click is generated if you close window with keyboard (ALT+F4) with mouse is over the ads.
What I'm wondering is what happens when someone is blocked from clicking because they already clicked - do they just not see any ads or are the ads there and they just can't click? If the ads are gone entirely, do I just have a big blank spot on the page, or can I assign some default text/image to be displayed?
On YOUR server you CAN detect when multiple clicks come from same IP. It's up to you what to do then: fill the space with an alternate banner, insert an image, ... or even ignore, and continue filling AdSense code on your pages.
humn, let me see if i get this right, the publisher is now responsible for the user only clicking on 1 ad? can't go back and try other advertisers to see if they offer what he/she is looking for? and if they do click on various ads, you (publisher) should have a way of prevention for that? WTF!!
In my opinion publishers don't need to do that way of prevention. Google has it's own antifraud click methods.
adlogger seems to be the best. just make sure you install it correctly so that it will disable the ads from showing. I have used adlogger and it does report many false clicks as it counts right clicks as clicks also but I believe its the best program out right now. I wish Google would just make a program that can atuomatically do this for publishers it would stop so many invalid clicks
I wish Google would take care of their business-look at ip addresses, and negate the repeated clicks from the same ip to the same advertiser. Geeeez, here i am getting .01 a click and i have to also invest in some software that was developed by a former G employee? that probably suggested to Google that the publishers, should be the one's keeping track of multiple clicks to the same ads.
