My question is, is the size of window required to get a pretty smooth line different for each website, reliant on the level of traffic, or...? Anybody else care to post how big a window required to get a smoothed moving average of their AdSense income? Of course, this presumes a relatively stable website (e.g., if you just made a wrenching structural change last week, there probably shouldn't be a smooth line in moving average income at that point.)
Note: I think this is an abstract enough topic that it doesn't violate AdSense TOS.
Adding new pages can also make a big difference. Sometimes a single new page can drastically affect income.
As far as the window goes, I think 30 days is probably a minimum time frame to use. 90 days may be a lot better.
The short answer is you probably can't get enough data for future predictions. When projecting the future, an average can really only work when the input behaves in a regular, consistent manner. Even then, you may have an average but it won't tell you anything specific about future trends.
Adsense is extraordinarily complex and your site is just a tiny piece of a very big dynamic puzzle. Just when you think you get enough, all the parameters will change.
On a somewhat related note; What do you use to make those statistics?
I would like to know my moving averages as well. Moving averages, sounds almost dirty ;)
I use Microsoft Excel.
Steps
1. Download the report in CSV format
2. Open with Excel
3. Get EPC by adding the earnings of seven days by clicks of seven days. Once you get the formula right, you can copy it down and fill the whole column.
4. Graph it.
When I do it by single topic I get very different results—wild swings up and down. I had chalked this up to game-theory instabilities in the AdWords keyword markets, particularly in low-competition markets. But maybe this is over-thinking it.
Anyway, this pattern of topic swings and general stability has concinved me that all posts about how Adsense was great or terrible on this day or week came from people with single-keyword sites. I don't think someone up in Google corporate is looking at a screen going "Oh my God, Adsense is up 300% today! WHAT'S GOING ON GUYS?"
Also, regarding CSV Adstats, I see it is on a France website: nix.fr - Is the program in French? Also wondering why it say's this: "Warning, This beta version will stop to work the 12/07/2004" P.S. The fact is stops working soon and the bad English does not give me much confidence!
What happens after that date, oddly it does not say anything about that from what I can see?
I actually log my stats 4 times a day at the same times to make sure nothing funky is going on (like some way off target or raunchy ads being displayed). All depends on your site(s) volume if that much attention is worthwhile.
