Amit has posted some analysis of his AdSense earnings since the changes that AdSense made two weeks ago to the clickable zones on their ad units.
Amit says that his CTR has dipped slightly and his eCPM has remained fairly steady.
I thought I’d take a look at the same figures of my own AdSense earnings (I run AdSense on a couple of my other blogs but not ProBlogger).
Here’s how my own stats look (I’ve stripped them of actual figures as it’d break AdSense TOS to share them).
I’ve gone back two weeks before the changes were officially announced by AdSense (on the 15th November) so that you can see the trend before the changes were made.
Here’s how it looks:
It’s an interesting graph on a few levels.
I should say that the interpretation of the figures are made more difficult because we’re just entered the ‘Silly Season’ where advertisers begin to spend more on advertising in the lead up to the Holidays – this traditionally pushes eCPM up a little.
Having said that – the raw figures show that CTR (click through rate) has definitely been lower (in fact some of those days are my lowest CTR for a long time) but the eCPM (the earnings per 1000 impressions) have remained steady – and in fact have had some very good days (or at worst, considering the ‘silly season’ seem to have remained steady).
It is too early to tell (we need another couple of months data after Christmas to see the real impact) but at least on my figures the expected hit in earnings hasn’t been too bad. My own actual earnings are steady (if not slightly up).
However I can’t help but wonder what earnings would be like if CTR were higher with the increased eCPM that I’m seeing.
How do these figures fit with your own?
