- what's range of clicks are we talking about?
10, 100, 1,000, 10,000 ..
- what duration
<1h, 2h, 3h, .. 1day, 2days .. 1 week, weeks
- what size of traffic is your site
- what %'age is the ctr fluctuation compared to the last 12 months average?

Any or all the above can sway the call on what's "normal" for you.

And to add to what Hobbs said, YOU see the same ads. That doesn't mean that all of your visitors do....

I don't like the feeling of being a guinea pig either, though over the years I've come to accept that Google actually isn't out to mess with my head. They may be messing with the system as a whole, or it may be random.

That only means that they've succeeded at the ultimate 'messing with your head' PC, look into my eye and repeat after me: subliminiminal.

On topic, even if you and your visitors are seeing the same ads, it does not mean advertisers are paying the same. The uncertainty and complexity is well designed for publishers to never be sure about anything, still think they're not messing with your head?

Is not a big site, but here the specs
2000 uniques daily
usually at list as of 3 days ago was getting 300 clicks a day.
Lol I guess is just my site then, purplecape you might have a point maybe now people are seing different ads, at I dont know I was just getting happy that numbers were getting back to normal after almost 6 months of down turns :(

lol just check my stats right after my last post, got a hugeeee click dump ehheh Yessssss I love google again at list tyl things go wrong againg :)

Well, Hobbs, if you put it like that, of COURSE they are messing with my head! I was trying to address the feeling of being a guinea pig--and from his later posts it was just a click audit delay.....
