Adsense is being presumptuous!

I am more than health!

Hi GodSenses,

Well our forum started by topics around “Health”. Now that we are adding new page and topics, adsense shows ads for 'general health' issues instead of really focusing what is actually on the page, for example 'buy a new camera".

Have you encountered this issue before?

I am thinking that the adsense engine is showing Neural Networks behavior, it has taken the initial data as the training set and now forecasts everything with a huge bias.

I appreciate your comments and thoughts.

How are people getting to these threads? Via AdWords or via the health-discussion forum?

I have the same issue. On a subject I have maybe one page about, I get ads for that subject all over the site.

From my experience, it takes some time for Google to work out what a specific page is about. If you add a page on "Digital Cameras" to a site that is usually dealing with "Trips to Elbonia", then you will see ads for "Elbonian Hotels", "Elbonian Airport Transfers", etc. during the first few weeks, even on the page on "Digital Cameras". Can take up to eight weeks. But at some point, Google will display the right ads (i.e. digital camera ads on a page for "Digital Cameras", even if the rest of the site has a completely different topic).

It has been years for me and the issue still exists. To use a fictitious example, if I have a site on cars, I'll see Chevy ads on the BMW pages, while at the same time there will be BMW ads showing on the Subaru pages, and then Subaru ads on the Ford pages, etc.

Hey Jane, here's a test: type a typical search query that a user will be coming in on and evaluate the ads. The ads could be targeted for your users in that way, as well as from whatever site they'd just come from.

Maybe it's a flaw in the algo if Google is showing a more expensive or well-clicked ad and overriding what's on the page. I see it too.

I'm pretty satisfied with the targeting on specific topic pages of a broad subject. For me it seems that a key word or two in the html file name with page title and H1 header spot on topic provides good targeting quickly.

It also helps (I think) to move navigation code to bottom of page and use google hints appropriately.

However, if someone bids high enough and broad enough then they will sneak in most anywhere.

Also, the site targetted ads have a tendency to dominate the entire subject. I asked G to turn on CPM ads today to give them another shot.

ps. I've noticed when G gets confused about a page it runs home to mamma to shows general site topic ads.

Martinibuster, I think you are right, they are targeted better when entering a page from a search query than when just going from page to page looking through the site.

However, I think the ad targeting on this one site in particular still leaves a lot to be desired, and many unrelated ads still show up on each page. On most of my other sites the targeting is better, but I think the rest most likely have a bit tighter themes.

Yes, when you look at a page, the ads are tailored to what you have been doing (that google knows about). Often, it is based on the pages you were surfing earlier that Google could track. And then there is geotargeting too. It is not uncommon for me to visit a US tech site and see home loan ads from India! Does not mean that a normal visitor to the page is seeing them.

Doesn't really work for me that way for me because of the following :

Yes... their support confirmed this when I asked why my ads were not targetted. My site covers a broad spectrum of topics but based on one main theme. You could even consider EVERY topic in the world to be connected to this theme in some way, but what happens is that the more expensive ads for the site's theme overrides the ads for page topics. So the only way to get ads to appear for page topics would be to slap on the maximum ad blocks. That way, the last one or two would likely be on-target, but too many ads is not what I want, so I live with the situation.

ps. I've noticed when G gets confused about a page it runs home to mamma to shows general site topic ads.

yes... mommy... mommy...

>>>Doesn't really work for me that way

You have to type the exact query in the exact search engine that your logs say your visitors came in from for it to work. Plus, those keywords have to be not so obscure that there aren't that many ads for it. For example, if you're ranking for longtail obscure keywords, then you're not going to be getting that much inventory for it.

I visited your site and typed your keyword branded domain name and saw that adsense was displaying perfectly targeted ads for that. Couldn't be better.

I couldn't find any other keyword phrases you were ranking for to test if the search query site-entry relevance wasn't working, as you claim, because you don't seem to be ranking for some of the phrases in your title tags.

I typed in a number of your title tags and didn't find you relevant for any of those in the top three search engines, so couldn't test the relevancy.

But this site might not be the one you're having trouble with? It's a different one?

intresting. so if thats the case it can explains the downward cpm too, more expensive ads are shown, they are less targeted, less clicks, smart pricing takes note,...

i use 2 blocks maybe i should experiment with 3.
