So I add some AdSense code to two technical tutorials covering project management concepts for industrial plant maintenance projects. I check the ads to see what is appearing and several of the pages for each tutorial show an ad that reads "Bad Breath? ...". Right. So the page visitors to the page are going to be asking, what? (Yes, I've put that ad on the block list.) I think the ads was keyed off of the word "scope" which is used in the context of work scope. Not the mouthwash...
Bernard, I have noticed that until the specific Googlebot visits it is pretty random. Took about 4 days for my first site to start serving relevant info. I think if you are patient and your keyword and descriptions are right, you will be fine.
It is just a theory mind you, if a site has 2 keywords/phrases that AdSense would use choose which add to show. It will always choose the more popular/expensive out of the 2. One might think it would choose on pure relevance, but I suggest that the dollar amount has a much greater factor.
NewComputer, the ads I'm seeing are already very well targeted. I have not seen one ad that didn't make sense to me with regards to the on page copy. ThinkBling, based upon what I'm seeing the ads served have more to do with which keywords are appearing on the page more frequently. I'm seeing 3 ads currently on one of the "scope" pages in question related to the word scope. The other ad is related to the subject matter of the page. I did a quick informal check on AdWords and a top position on scope can be had for less than 10 times what a top position would cost on the subject related phrase. Interesting.
The reason for that previous statement of mine was because of my experience. My main-page is a category directory of all the different items for sale. Some of which are baby products. With no fail everytime one goes to ThinkBling.com the ads are for baby products which must be the highest revenue words.
It appears that the word "bling" has been associated with the word baby: http://www.google.com/search?hl=en&lr=&ie=UTF-8&c2coff=1&q=bling+baby As you have that word in your title and the large baby category near the top of the page, I'd say that Google sees your page as relevant to baby stuff.
