Your experience isn't unusual for a new site/account.
It can take Google a couple weeks or so to asses the value of clicks from your site. That's called "Smart Pricing" and basically it means they charge advertisers less for clicks from some sites and pay the publisher less as well.
The idea is something like clicks from a "how to take good pictures" site might be worth less than clicks from a a site that reviews the latest new cameras.

Well the good news is that you're off to a good start. But as ken_b said, this is not unusual. You really need a few years of data to understand how your site will really perform.
Yes it could be related to your design, and you could easily find out - just set it all back tto the way it was at the beginning. If your revenue goes back up, then you're done.
Otherwise it could be related to Smart Pricing, seasonality, the economy, current events, Google updates to the algorithm, the weather, or something else.
Day-to-day my statistics look like a picket fence. Some days higher, some days lower. There is no way to accurately compare one day to the next.
Month-to-month I can see seasonality trends, where the number of visitors rise and fall - it looks like a sine wave. Due to seasonality, it doesn't make sense to compare one month to the prior month.
Year-to-year I can pretty much match up the corresponding months. October 2009 is much lower than July 2009, but it's a little higher than October 2008, so I consider it to be a successful month... even though the revenue was only around 80% of July's totals.

Forgetting the time based variations. My experience over years is less ads per page equal higher earnings.
That's quite the opposite of what the google people suggest when they email.
I've not figured out the system, but I have figured out that for me a single ad in the footer works just as well as big ugly ads placed where they recommend them. I don't know why, but it makes my pages look tidier so I'm not complaining.

Just re-read the opening post - Other members have observed that removing ads from poorly performing pages can increase earnings overall.
See this recent thread: [webmasterworld.com...]

One other factor which the OP didn't mention was the CTR. Are the original sites seeing reduced CPC or just fewer clicks?
A site with a good level of returning visitors will see an early peak in clicks which will then tail away as visitors see the same or similar inventory on subsequent visits. Regular visitors also quickly become "ad blind".
One other point is that you need to make heavy use of channels to track exactly where your clicks are coming from. Not just which site or even which page but which position on the page.

It's likely to be a usual fluctuation.
However I cannot have ads on my galleries for example, which generate hundreds of thousands of impressions per day because the CTR is too low.
It essentially causes the entire account to earn less after a couple of weeks. One channel DOES effect others. Don't listen to anybody who tells you otherwise.
I think it's only going to be a problem though, when one channel has a significantly low CTR etc.

|I'm wondering if it's possible that Google gives less money per click as you increase the number of ads in your account? |
No. Your earnings are based on the value your ads provide to advertisers. Though the number of ad units on your page (and other elements of site design) may affect your earnings, Google only wants what's best for you, your users, and the advertisers who bid on your inventory.
I agree with most of the advice you're getting on this thread. These guys know what they're talking about.
The one big caveat I'd throw out there is that while less ad units may lead to higher revenue for some publishers, our data shows that most publishers do not benefit from removing ad units. Of course, YMMV. Channels are a great way to determine what works best for your site.
Before you start adding and removing units, though, I'd suggest experimenting with size, position, and colors. Switching from a rarely-used size to one of the top 3 ad formats [google.com], for example, can often make a huge difference. And moving an ad from the bottom of the page to above the fold can really increase CTR. Just my two cents. :)

ASA I'd be really interested on your take on the above.
Why does my main earning unit suffer when I add ads to my gallery which has a very low CTR?
I've tested it over and over and every time overall income lowers. My adsense account analyst was puzzled and couldn't explain it.
The same is true if you add a bad performing website to your account, the entire account suffers as a result. It's so frustrating having to treat of egg shells.

A few of my older sites ( > 5 years) have shown this behaviour. I tested reducing ad units (kept 1 ad unit plus 1 link unit) then max'ing them out (3 ad units + 3 link units). More units indeed meant a healthy increase long term. The trick for me atleast, was not to get too excited over rising CPM or EPC of fewer units but keeping an eye on the bottom line (revenue.) Higher EPC means nothing if CTR is low because of low exposure of ads (and EPC can only get high to a limit.)
For these old sites, it seems I just can't have enough of these ad units.
However, a few of my newer sites have shown the opposite. Fewer ad units mean higher CPM, EPC and revenue.
So, again, with AdSense, it's all in testing and experimenting.

realmaverick, this could be any number of things, and I'm afraid I can't say much without knowing more about your site, your implementation, your channels, your history, etc.

Thank you to all who have replied for the good advise and words of encouragement, this forum is awesome!
In my original post I forgot to mention that the overall CTR of my account has remain approximately the same when I added more ad units, only earnings is geting lower.
And when I track each website individually I see that my site 1 et 2 (the most visited ones) still perform well as far as number of clicks per day. And my less visited webistes have a good CTR also but of course generates less earnings because of the lower traffic but I was happy to make a little money from these sites too.
What is sad is that revenue coming from my site 1 and 2 is getting lower and the only difference from before is that I now have more ad units in my account.
I basically have 2 ad units + 1 link unit on each page which has a large amount of content, and 1 ad unit + 1 link unit of each page with less content. I use the top 3 ad format as much as possible, especially the large rectangle.
I know that I have only a few weeks of data and I'll continue monitoring closely the performance of each ad unit using channels, will also experiment more with position and colors, etc. and hoping that earnings will get back up.
