CTR and eCPM....a method to their madness?

One day there there up next there down.....

my traffic has been steadily increasing since my site went live but these numbers seem to bounce up and down.

What exactly are they based off of? and furthermore what should I be doing to make them increase?

impressions / number of clicks = CTR (click through rate)
(total earnings / impressions) x 1000 = eCPM (estimated cost per thousand impressions)

To make them increase, you basically need more clicks on your ads OR, less total traffic and keep the number of clicks you have. Note that the second option usually sucks because your earnings won't ever grow. More traffic & good content will insure that the ads stay relevant to your page.

Be sure theree aren't too many options for your users. You want: "read, read, read. Hmm, now what *click*"

hmmm now that I check my stats my clicks have been decreasing...

yeah my site could be too cluttered. I'll work on simplifying things. thanks.
