The increase is not due to those same 5 clicks. Its because you might have add more page impressions and earned $0.01 from them.
multiple clicks from the same IP are paid normally.... I can vouch for that up to about 4/5 clicks from same user
I've had end of day CTRs at 100% on some of my webpages. It's not rare but most likely on pages that get very few impressions.
Google can be very mysterious like that... it's impossible to tell whether a click will bring you in 1 cent or 1 dollar! Hope your earnings get better!
Do you have any link units on the site? You only get paid for those clicks if the visitor then clicks on another ad on the resulting search page. Vito
Time for you to look for Adsene Alternatives. if you make a penney what is the use of having a web site? See if you can find some other way of making money. Thanks
