Post subject: Site visits vs. AdSense impressions
|
|
|
Is anyone noticing a significant difference between the number of visitors to a page where AdSense ads are displayed (as revealed by your site statistics) vs. the number of page impressions reported by AdSense?

| I'm assuming you mean the number of visitors to your site since AdSense does not report Impressions by page, but yes I have. My overall AdSense Impressions : Site Stats is down about 15%-20% from where it was a couple of months ago. |

I don't mean that my impressions are down.
On any given day, the number of visitors to just one page on my site (according to the site statistics), is much higher than the total impressions shown by AdSense.
For example, if 400 people visit a page in a day, and that page has relevant AdSense ads, shouldn't the AdSense stats show at least 400 impressions for the day?
My impressions are being reported as significantly less than the number of page visitors.

I realize that. By saying "My overall AdSense Impressions : Site Stats is down about 15%-20% from where it was a couple of months ago," I mean that the ratio of AdSense Impressions to my site stats has declined.

No. From the "My Account" section of the AdSense FAQs:
| Quote: | 3. Why do I detect a different number of page impressions than what shows in my reports?
We count page impressions only when our ad code is executed by a user's browser. There are therefore several factors that would cause a discrepancy between the page impressions you register and the page impressions listed in your AdSense account. Instances that wouldn't execute the code include:
Spiders, robots, or crawlers from other search engines
Browsers that don't have JavaScript enabled or don't support JavaScript
Browsers that don't support the <iframe> tag

| And by the way, Public Service Ads are included in the AdSense Impression count, so you don't need to have relevant ads for an Impression to be counted. |

I guess I can't explain much without violating AdSense rules about discussing statistics.
I'll let it suffice to say that I recently experienced a significant increase in site traffic due to print advertising and that increase has held. At the same time, there has been no corresponding increase, not even a small spike, to AdSense impressions.

Bobby, that corresponds with what I'm saying. Your site stats have increased but your AdSense stats have not which means you've experienced a decline in the ratio of AdSense Impressions to your site stats. |

What I think Bobby is saying is that he is getting X number of page impressions according to SBI, but he is only getting X-100 impressions according to Adsense or something like that. Is that correct Bobby?
I don't know what that would mean, do you have Adsense on all of your pages? Maybe the pages that don't have Adsense on them have seen an increase in page views?
Besides that, maybe someone else can shed some light on this. _________________ Robert

| Gosh, I thought I gave an adequate explanation. I confirmed that I have had the same experience and I referenced the language in the AdSense FAQs where the reasons are given. |

Yes, except for the SBI part. I don't use SBI. My site statistics are provided by my host.
Yesterday, for example, twice as many page views were recorded as AdSense impressions.

The site statistics provide details on how many page views are realized for each page. I'm not considering page views for pages that don't have AdSense when I mention an increase in page views.

My site statistics tell me when spiders, robots, etc. visit from other search engines, so I can subtract those out and see how many visits come from other sources. For the site that has resulted in the huge increase in overall page views, visits by robots, spiders, etc. is an insignificant number.
As for the other 3 reasons given above, it's certainly possible some of that is happening, but it seems very odd that that would all of a sudden have such a significant impact on the overall numbers when it didn't previously.

Have you taken into consideration the number of visitors who may have blockers installed that won't permit javascript, iframes, and specifically Norton Firewall which I understand now specifically blocks Adsense as well as CJ?
Also, a page view can register with your site stats even if the page doesn't fully load. However, Adsense needs to fully load for it to register an impression and it takes a few seconds or so for Adsense to load.
Other than what is mentioned above I don't know why you would see a big difference. Contact Adsense through your account admin and see what they have to say, at least then you can discuss specifics

It never ceases to amaze me how willing people are to install softawre that interferes with the proper display of web sites, but I never realised Adsense (or any syndicated javascript) was blocked.
It's one thing to disable automatic downloads and prompt for ActiveX and Java (NOT javascript) in your browser settings, but the rest is pretty harmless at worst.
I think it just depends on how you use the web, but most of the sites I visit don't bombard me with pop ups or anything else. Certainly not twice, if you see what I mean.
Don't you want to use your own judgement rather than rely on inflexible censors in software form?
Just my opinion,
Charlie. _________________ "Before I speak, I have something important to say."

Yes, see the post just before yours.

I would venture a guess that more than 90% of these users have no idea what the full ramifications are of these programs. It's not the user's fault. It's the software developer that has willy nilly blocked (and overwritten in some cases) the technology required to effectively use the Internet today. Blocking affiliate links is a perfect example. |
