Interesting Stats

Adsense and Adwords differ greatly

For one of our sites we receive 100% of our visitors from PPC. The same site has an adsense banner on every page.

Here's the problem - every day we average paying for 12,000 clicks through google and overture (8,000 google & 4,000 overture), yet our adsense reporting area only shows an average of 6,500 impressions per day.

It seems awfully convenient for google & overture to be charging us for double the amount of visitors that adsense says we're getting. It seems we could be paying for clicks we're not getting, or being underpaid by adsense, or both!

Is adsense a reliable source for true impression numbers? Does adsense always display for every visitor, or only some?

Anyone else experience something similar?

IMO, I would trust AW and OV over the Adsense reporting.. Sorry I can't be of more help..

No it doesn't... which is why they have the alternate ads systemw where you can specify a page URL with some other ad networks ads.
The reason is geo targeting. Many a times there are no ads for a region or country.

That's an interesting observation. It might well be that that many people click the link and immediately regret it and go back before the page loads. That sounds like an awfully big difference, though.

(Or maybe it has something to do with kitty litter.)

I have an opposite experience.

Page impressions in AdSense are actually the ad impressions.

I would say geotargeting too - Just because you always see ads, doesn't mean that someone from another country would see them too.

Take a spin around your site with the preview tool set to different geo-locations.

I've had the same problem when I first started with Adsense. New publishers don't usually get consistent showing of ads, therefore the discrepancies in reports.

I've only been with adsense for 4 months but learned to trust Google completely. I sensed that they are the very few trustworthy PPC & contextual ad companies out there. Even though they don't reveal much, I believe they are giving publishers more than 50% of the total earnings per click.

I've tried many other companies and will never go back to them again.

Perhaps try dropping the adwords or overture for a day and see if each one is accurate by itself or if both are over by about the same amount. If one of them alone is right on the money (or very close), but the other is not then you have found your problem. If they are both over by roughly the same % then you should go with the geo targetting issue. If your page is large and the adsense is near the bottom of the code then that could also cause it and that should definitely be looked at. No sense paying for a click if they can't even stay around til the page loads.

What do your server logs say?

I had an interesting related observation just today. I was switching a page from named channel tracking to URL channel tracking a few days ago, but left the name channel tag on the page and forgot to delete the name channel on my account, so it was getting tracked by both channel name AND URL for a few days.

Turns out on the second complete day of this overlap the name channel was 490 impressions vs 481 via the URL and one Click higher, whereas one would expect them to be identical. On the third day they were 578 and 569 respectively with the same amount of clicks. Hmmm.
I even double checked to make sure no other page was using the same name tag. Anyone else observe this?

AdSense impressions number is consistently 20-25% lower than page impressions measured by Urchin for all of my sites.

I've been using adsense and seeing this discrepancy since summer 2003. This should be because of the ads not delivered to some pages once in a while. Google states somewhere that adSense impressions no should not be used as a measure of page impressions.

I track by channel and url. I don't get many impressions at all, but there's a substantial difference in the number of impressions tracked by url vs. those same pages tracked by channel. I don't understand it, but I'm not going to worry (just keep reading for something I might be doing wrong :) ) until my impressions are higher.

I posted this elsewhere the other day but it bears repeating. Manny people never see your ads unless you are extremely lucky.

Many people use personal firewalls like Norton which also blocks ads. I've seen my site on a few computers that had ad blocking enabled and they were all gone except for the few I serve up directly from my server.

So, out of my 36,000 pages a day:
- deduct search engines crawling the site
- deduct the google media bot
- deduct no ads on personal firewalls and banner blockers
- deduct google PSA ads

I think you see where this is going....

Good points incrediBILL, I wasn't even thinking about the bots.

Looks like Google was correct with the stats, as they gave a thorough explanation. They let me know that even if someone types in keywords on yahoo to get to our site, adsense doesn't recognize that, and does not display, because yahoo owns overture. And the same goes for other search engines not in the google network as well.

I was under the impression that adsense recognized keywords from any search engine and displayed accordingly. That is obviously not the case.

I'm not sure I'm understanding that answer.

If someone goes to Yahoo, searches for a site using the keyword widgets and clicks on a search engine result to go to widgets-domain-here.net with an adsense ad on it, Adsense won't show or log an impression?

That's not correct.

I've got to be missing some piece of the puzzle here.

Nope, that sure isn't the case. Adsense matches ads to the text that is on your page(s). It could care less how someone found your site.

MikeNoLastName,

The discrepency between URL tracking and Channel name tracking might come from various cached sources, which are displaying an older version of your code. It could easily acount for that small difference of 9 impressions. There are so many versions of every page around (in google's cache, askjeeves cache, site strippers, web browsers ...)that I wouldn't expect the stats to come out equal.

That's a good point, creepychris. I wish they'd tell me if my ads were getting clicked on somewhere besides my site, tho!

I had a senior account rep at Google confirm that clicks from Overture sites will not trigger an adsense ad on our site.

They wrote:

"As you may already know, Overture is not a member of the Google network. Therefore, the 2000 clicks you received in your Overture account would not impact your number of AdSense impressions".

I'm just the messenger.

Does that mean google is screening the referrer to the site? Why would they care HOW someone got to a page with their ads on it, if someone clicks the ad they make money.

It's just stupid.

Wonder who else they filter?

More importantly, do they filter out ALL Overture links from all Overture partners?

Do they filter out the "additional listings" beyond the paid listings on overture?

That would be real easy to defeat, sign up for one of googles competitors and write a little javascript that determines bases on the referrer whether Google gets displayed or BrandX ads.

I know posting URLs here is verbotten, but if someone has a working example of an Overture link to an Adsense site, I'd like to see it - send me sticky mail, as if it's true I got some javascript to start writing.

This statement from senior account rep has costed me 20 cents. I clicked on my own ad from MSN & Yahoo searches for one of my cheapest keyphrases in my Overture account. (I can't wait 2 days for channel data and testing.) I saw the landing page with AdSense ads on it, very well targeted ads. If the AdSense is shown, the AdSense impression must be counted also. If it didn't count, someone clicks on it and the result is a buy. How does Google treat this sale? A sale with an invalid click?

The above statement can not be true. This senior account rep has missed something. She/he doesn't understand the connection between a click and its impression.

Hmmmm....I sent an email to the Google rep asking for clarification. I'll post the response here. Maybe they'll credit you the $.20 Rocky!

Do any google adwords or adsense people post on these boards?

I bet they're just confused about what the situation is. They must somehow think you also have Overture ads on your website or just not understand why you are talking about Overture.

The best thing to do here is resort to your own webserver logs. How many clicks in do you see in your own logs?

You should be able to identify clicks in your logs that came from Overture and from Google and verify that they are billing you correctly.

You should be able to estimate how many AdSense impressions you should have based on the number of page views in your own log file, and cross-check that with AdSense stats.

Once you have data based on your logs you should be able to forward that data to Overture, Google, and AdSense and demand an explanation for why your logs show something different than their statistics.

I don't think Google is going to care or pay any attention to what a competitors stats show, but they ought to pay attention to what your own logs show.
