Today, my site got the highest number of visitors its ever had in 3 years. Over the past 3 months my traffic has been increasing steadily. Everything looks great and I'm working my azz off creating useful and quality content. Thats the good news. The bad news? Google Adsense continues to perform like $hit and report results nowhere near what my logs show. Impressions are three times less than what my weblogs show. Its so far off its ridiculous. Clicks? ZERO. I've never seen my website perform this horribly with Adsense over the past 6 years I've ran it. Is this program for real?!
What are you using for your website logs? Many/most logging systems will track any hit, from any source, which includes spam-bots, search-engine spiders, etc.. Adsense and Analytics will only track "real" visitors..
Lets put it this way. I use several analyzers and yes I am aware there are discrepencies. However that does not explain a significant increase in page views, multiple increase in uniques. Adsense reports XXX (yes hundreds) impressions - hundreds of times less than my pageviews. When pagviews and ad impressions aren't close that is a reason to be concerned. I've checked my logs and there is nothing in it that looks strange. I've looked at the ads on the page and relevancy - nothing unusual. Links and text colors are chosen appropriately. Placed appropriately too. Resulting CTR% is absolutely abyssmal. Calm? Heh if you were in my shoes you'd be pissed.
So, have you checked that your adsense ID is still on your adsense code? If it was changed on some pages by a hacker, then it could results in what you see.
That does sound weird. And we all know that Adsense support is not very responsive. How long has it been like that?
I've had similar problems , but it was more based around blogs on sub domains and Adsense channel setup e.i. www.mydomain.com, mydomain.com. I surfed all over your sites and I don't think it is the same issue. In the end I replaced all my adsense channels with the mydomain.com format (eliminating the www) and now have a higher impression count. I verified this by having both the www.mydomain.com and mydomain.com channels both active and I could see the difference in numbers. It's worth a try and takes only a minute to do.
I also looking for this because mostly when i compared the Adsense account impression with Google Analytics it does not same . . .
Where is your traffic coming from ? I wonder if Adsense is disregarding traffic from say, India or China, or some other locations..
I redirect www (or the other way around) via htaccess so you eliminate the two domain thing. Is your niche very techy, or opensourcy? That group of people are prone to using ad blockers, so they'll really decrease your adsense impressions : pageviews. I have one site that is more techy than the others and it has far lower impressions than pageviews AND really low CTR. Geeks don't make good adsense customers
Are the adverts on every page? Or do the pages getting lots of views have ads on them? Could also be an issue with adblockers depending on your site's niche
