If there are no advertisers for that topic, then you may be better off looking for affiliate advertisers.

If it's just that AdSense is getting confused, have you used section targeting to ignore irrelevant terms in your page, and highlight very relevant terms in your page?

section targeting? I never heard of that can you please explain more?

thanks for the reply

Google it.

sorry i already did and got the answer, never heard of it before tho :s thanks for the tip

one more question is that any equivalent for that to tell Adsense to completely ignore a work in the whole page or i have to section target each instance of this word?

You would have to section target each word.

But I'm not sure that would work well. If you have a problematic word, consider replacing it with a synonym.

You also may need to rewrite the article itself, if it's not triggering the ads you had expected. If the overall focus was clearer, Google might ignore that tricky keyword.

I use section targeting if, for example, I'm writing about a photographic film scanner and I happen to mention that an example image came from a photograph taken in Prague.

To avoid AdSense leaping on the travel-ads bandwagon, I just wrap the paragraph about Prague in ignore blocks, and most of the time it seems to work.

I just section target out the entire body and let my ads work off the keywords. I have very little copy to begin with so I don't know if this would work in every circumstance.

well section doesn't seem to work for me
I tried tagging every culpit word with the ignore tag and add importance to the "good" words, and still Adsense just seems want to be picking the one single word *but that is repeated* I don't like :(

akhater, have you looked at your site with the adsense preview tool, to see what advertisers are available? does it match what's showing up on your site?

it sounds like an issue for adsense support.

akhater, it's not so convenient as that. Once the AdSense bot has cached your site, you have to wait for it to visit your site again before any text or section targeting changes get noticed.

I think the interval can be several weeks, but hopefully someone with more experience can fill you on more reliably. Leave the section targeting in place and wait to see whether things improve.

Note that ASA said a couple of months ago [webmasterworld.com] that "using section targeting on just one or two words is considered to be manipulating regular ad targeting, and is prohibited by our program policies."

Well, that's ridiculous. If AdSense didn't leap on single occurrences of words and show completely irrelevant ads, we wouldn't need to wrap single words in an ignore block.
