What I'm asking is if you have a site based on traveling widget jobs and "traveling widgets" costs say 5.00 per click and "traveling widget jobs" pays 3.00 per click
and "widget jobs" pays 2.00 per click and "widget" pays 1.00 per click, how does Adsense determine which rate/keyword is right for the page the ad is displayed on?

I mean, if your site has content sections about everything related to "traveling widget jobs" and anything relevant to widgets in general, each page theoretically, would have more relevance than others for certain words. How is that determined?

If I use adwords and bid two prices for two keywords, but ads for both keywords show up on the same page which keyword gets credited for the click?

If each page is assigned just one keyword then that rules out the "broad matching" which google uses in their search right? And if not, then how?

It has to be one supercomplicated formula, that is for sure...but I'm wondering what words am I getting paid for when a user clicks an adsense ad on my site.

shortbus... i think you raise a very interesting issue, but unfortunately i doubt that anyone knows the true answer to this except a small team at google. and i am sure they will stay tight-lipped about the algorithm.

my best guess is that they base the amount of your click on the "closest match". they have some sort of relevancy algorithm to determine which keyword is to be triggered by a particular page. in addition to the possibilities that you mentioned, i think that smart-pricing plays a big role. they want to incentivize publishers who deliver converting clicks and do so with higher payouts. those that send poorly converting clicks are weeded out of the system with lower payouts.

if you are asking because you want to know if you should omit words from your pages, or focus on particular ones... i suspect that this is a trecherous path. i doubt you will be able to reverse engineer the algorithm, and therefore any energy you expend toward this end is fruitless. i think your best bet is to write naturally about a specific topic on a page. unfortunately, we need to leave the rest up to google. they will never reveal their hand.

in other words, the time you spend trying to figure this out (probably impossible), is better spent building more pages - because that is certain to earn you more money as a publisher.

I thought of it because I have an include file that includes an adsense skyscraper on the right hand side of my forum pages. Rather than create a "channel" for each forum, I just use the one ad channel. "most" of the ads are the same for each forum, but not all of them. I have customized the meta data of the pages to be forum specific.

So my thought was more along the lines of changing the title/meta description/keywords back to the basic theme of the site, rather than specific to the forum topic, since the forum topic's "targeted adsense keyword" may earn less than the overall site topic would earn. If meta data has any relevance at all to the adsense keyword, then it would benefit me to gear it more towards the higher paying keyword, instead of the forum specific ones(not as specific yet still highly relevant).

Of course, I'd have to weigh the increased earnings against the possible decrease in search ranking do to the meta data change, as it wouldn't be a 100% perfect match to the content, but rather a general match and tht might decrease traffic...

If I were in this situation, I'd go for the maximum traffic and provide plenty of on page opportunities to send that traffic to the higher paying subject areas on my site.

maximum traffic is a must for me right now, but that's because I'm still out of google. I'm TOTALLY changing up my revenue model, to include more google ads (I only really have one right now) and less direct to company banner ads which come with my sponsor packages.

It will allow me for less time on the phone making sales and more time working on adding value to my site.

It's tricky, and I just don't want to make any mistakes...
