To think that they influence each other is as usefull as all the roulette theories.
There are really people beliving that there has to come black, only because red was 20 times in a row before.
But it's simple 50:50 chance for red or black,
regardless what happened before.
Question is: Regardless of the slight extra income these sites are bringing in all together, should I be putting lots of time into tweaking the ad blocks for the reason of keeping my overall CTR higher alone? Is that enough reason?
I know the answer to the question is probably "yes"... but... just want to get input from others with the same limits on their time. I feel like it is a better use of my time to keep working on the biggest site and let the smaller ones just add up their pennies. But am I shooting myself in the foot by diluting the overall numbers? (Assuming that higher EPC is a reward for higher conversion).
Have you been able to see an earnings drop overall EACH time you added adsense to a separate site? If so, was the drop immediate, or did it occur gradually over time?
Also, are you tracking stats by channel and/or url?
I have nearly every day an other top site of the day earning the most money.
5 different sites from me are strong enough for chances in the top site of the day game.
Special at smaller sites with only a few clicks a day, EPC can change 1:100 from day to day. One day 3 lucky hits with $3 each, next day 3 bad hits with $0.10 all together.
I think even big sites can not make conclusions based on statistic data. Nearly all descisions are based on feelings.
The day as I put ebay in the URL filter started bad. So I let them 3 additional weeks out of the filter.
The day when I started to test an other color scheme for the ads started good. It was designed as a test for one of my top sites, but so I immedeately distributed the color scheme over all my sites.
A statistican would exactly tell how long a test has to run, until it's a fact with 99% probability.
If it was me, I'd risk losing a bit of income simply to test whether or not the other sites were somehow affecting things. In other words, I'd remove adsense from the other sites for a few days just to see if epc rebounded on what was previously the better earning site.
Ideally, the adsense data from one domain shouldn't screw up another. But...who knows? Makes me wonder if I should put adsense on a new site I am developing because I would hate to screw up the other. Also makes me wonder if I should simply use another program on the other site, perhaps yahoo when it launches.
Has anyone else experienced this----having good epc on a site and then having terrible epc and decreased earnings after adding adsense to a second or third site?
It's probably coincidence. But I saw the same thing earlier with channels. Killing off ads on the poor performing channels (low CTR or low CPM) seemed to help the CPM in other channels, whether on the same site or not. (there are earlier discussion on that on here).
I don't have anywhere near enough evidence for this, way too many other things change from day to day. But I do give a new site or channel only a couple of weeks to perform well on Adsense, otherwise it gets other ads instead.

I've seen the same thing on my site.
We keep talking about its effect on Smart Pricing, but I wonder if something different is at play? Google may have an algorithm that penalizes publishers who add low-CTR pages, on the theory that this will discourage them from blanketing their sites with ads and increasing the rate at which visitors become ad-blind. There are weaknesses in the theory (like, "Why wouldn't Google tell us about it up front?"), but I think it's worth looking into.
