I just put the adsense up just over a week but never received a big change like today. Usually i received .2% - .7% Page CTR but somehow today I've checked the stat. and it shows 2.2% of Page CRT there are 3clicks within 134page impressions Any ideas?
Yeah you don't have enough traffic for the numbers to be statistically significant. Don't worry about it. If you saw a 10fold difference with 100,000 impressions it might be something to investigate, but if you get a few more impressions with no clicks your ctr will plummet. And if you get another 2 clicks in the next few impressions it will skyrocket. Don't worry about it.
