Yep, i got the same prob..

Dunno if you also use Adsense for search.. but i guess that is missing in my stats..

I also use Adsense for mobile pages, also missing!

I only use Adsense for content...

I see discrepancies too. Thought it was because I was still using some of the old Analytics code on some sites, but I replaced the code, and it still doesn't add up.

Of course, AdSense is run on Pacific time and my Analytics sites are all set to Eastern, but the totals are still way off.

But then - across the board I lose about 15 - 20% in Analytics anyway - pageviews, visits, ecommerce transactions - the whole shmear. I use it as an indicator of trends, not as something that is dead accurate. If I were paying for it, I'd probably be more upset at the discrepancies.

Anyone else noticing this?

It makes linking your Adsense account with Analytics useless.

It's not useless, but yes, it's certainly less useful.

I don't even compare Analytics earnings to that shown in the panel as I know only the one that shows in the panel is what I will receive

The biggest use for me of Analytics is determining where the biggest source of Adsense revenues come from in terms of traffic

In our case, we found that we get the most income from traffic coming from Yahoo Answers. So I may have slackened my participation a bit before, but now jumpstarted again because the folks coming from that site are who clicks most on my Adsense ads

With only 50% difference, Your Analytics earnings is very precise.

Here the data from one of my sites for March 1st to April 7th

$1,37 reported by Google Analytics

There is a link "Why are differences between the reports"

$323,05 is reported there

Google Adsense reports for this site

$1115,78
$620,46 from ad blocks
$495,31 from AdLinks

So there is 98,5% difference between my Analytics and AdSense stats.

What I gathered is that Analytics only shows revenue gathered through contextual income and not placement.

If you remove the placement income from the adsense report the 2 figures match more evenly.

I'm also having a big discrepancy too. I thought only adlinks are not showing on Google Analytics, only adblocks. Now there is a placement and contextual income difference as Rufal said. Maybe for now I'll accept that as the reason for the discrepancy. BTW Rufal, where did you get that info?

Advanced reports --> "Show Data by" (drop list) select "Individual Ad" --> Check the checkbox to show data by targeting type.

Generate a report for the past month (or 30 days, whichever). Click CSV link, and in a spreadsheet sort by contextual/placement and seperate. Compare the sum of contextual to what Analytics was showing me.

It added nicely up for me at least,. Though I find the analytic adsense reports quite useless since they are missing what is (for me) a big percentage. (at least enough for me to not use this analytical feature except to figure out which pages are earning the most)

There are some pretty granular explanations in this Help Center article [google.com] for why your stats may differ between AdSense and Analytics.
