Welcome to WebmasterWorld Guest from 220.127.116.11
Our website has several subdomains based on different topics each containing our adsense code. When we first built the sites everything was displaying propperly with adsense ads on topic within each subdomain.
We then got indexed and the strangest thing has happened. Most of our pages ended being listed in the supplemental dbase and our adsense results have gone haywire.
Index page for each directory within the subdomains is pulling relevant adsense ads just fine...BUT... all of the inside pages within each of those directories is pulling ads from one of our other subdomains which is completely off topic.
Does anyone have a clue as to what is going on?
The main thing happening is that they take a secondary key word and go with ads on that which are sometimes way off if they don't also consider the overall topic.
Sometimes it displays ads for NearbyCity Widgets, but the city is in Arkansas where i live. You will frequently get ads targeted to the geo area your surf from.
The problem will probably correct itself. If all else fails you can always go with a contexual ad provider that will allow you to choose what keyword you display ads for. Of course, this has it's drawbacks to, unless your page content is constantly about the same subject.
...some of the Adsense ads are for Atlanta Widgets and i don't live near Georgia.
Are any of the site visitors showing IP addresses traceable to Atlanta? Would be interesting to see if a preponderance of visitors from certain locales could affect the ads being shown.
I once ran ads for a specific section of one of my sites, but ads for that subsection started showing throughout my site to me, even though I wasn't clicking through on those particular keywords.
Oh, yeah, site-targeted (CPM) ads account for only about 0.32% of overall impressions, so we're seeing a plentiful supply of CPC ads (with great targeting).
I'm really freaked out by this, because I know it just can't last...
