Welcome to WebmasterWorld Guest from 184.108.40.206
I see my CTR starting to climb (almost double) after the first week. However income isn't following that trend -- it's basically gone down a little (not significantly yet).
After I make a change of this proportion, how long should I wait to decide whether it's "worth it" for me? I mean, it's great to double my CTRs and all, but that's not yet translating into income. Should I wait a month? 2 months?
See [webmasterworld.com...] for a method of working out when Smart Pricing updates on your account.
Were those pages also low EPC? I honestly don't remember, and I guess I should go back and see.
But it's a good question, because I see enormous variation in click value on my site.
As a side note, my current problem is that CTR has dropped by about a third recently. I can't figure out if it's seasonal, related to my site reorganization, due to expanded ads, or all three.
If Smart Pricing were all we had to contend with, then life would be simple, wouldn't it?
It could still be "site-wide page CTR" that matters. You knocking off a poorly performing page would up the average page-CTR for the whole site. My knocking off the footer ad block on a page with 3 adsense blocks might not have the same effect.
Anyway, we will see. For now I have replaced the adsense footer with an amazon recommends ad block.
However.. I will probably learn nothing... my revenue has been ramping up over the past few weeks as we approach the end of the year anyway (my site is seasonal, with the next couple of months being my best)... that effect will confound any attempt to work out whether it's a CTR thing.

Weekends are normally down 15 to 20 percent but not this one!
You need to do some testing. Our changes resulted in double the income overall on the test sites. The modifications were a huge success, and are now being implemented network wide.
Or look at your site average, and remove ads from all the pages with a CTR less than one tenth of it. Or some other fraction.
Don't overdo it. If it doesn't increase overall earnings, you may have done too much. If it hurts overall earnings, you have definitely done too much.
And, of course, on channels that are marginal--some clicks but not great--try to improve the CTR first.
I got my hands on an excel and calculated the deviation.
Two weeks before the change, deviation was 14,2. Since the change (10. nov - to date) deviation has been 15,4. Averages 104,3 and 148,2.
Hope that helps. :)
Yes, it does. But it is worth noting what it actually suggests: that your 30% average increase in earnings is statistically significant - because it appears to be of the order of a couple of standard deviations. What it doesn't do, necessarily, is attribute causality. That is, is your increase in earnings due to the changes you made, or is it due to other factors?
Most of our changes in earnings are due to changes in visitor numbers - earnings per visitor generally vary within a range almost irrespective of the tweaks we make to the site. However, I'm still waiting for the full SmartPrice impact of recent changes I made to feed through this Thursday/Friday, so we'll see if earnings per visitor go up then or not.
