...eb page. In order to be contextsensitive, the script must initiate an indexing when the page isopened and refreshed.Is there any reason to think that the indexing process performedby Google AdSense would be different from the process used byGoogle the search engine? None I can think of. Both indexingprocesses need to do the same job: extract core meaning from apage and compare it to a database.In AdSense, the database contains paid ads waiting for arelevancy match. In search,...

... the database holds keywords. But themeaning extracted from the web page could easily be identical.Therefore, one might get a peek into the Google indexingalgorithm by reviewing a series of web pages which displayAdSense ads, and studying the ad content.I studied the 30 or so pages on my site at www.poingo.com andchecked the AdSense ads on each page for relevancy to the pagecontent. Results were quite interesting.The site contains a number of pages which present the featuresof various software or service offerings. Verbiage on thesepages tends to be sparse and oriented toward key concepts.On these product presentation pages, AdSense did a great job ofextracting meaning.For example, the page offering Poingo Email Printer, softwarewhich creates PDFs, was accompanied by AdSense ads which allpertained to PDF conversion. Text on the page was minimal, butthe page title contained "create PDF", there were 3 keywordsmetatags containing "PDF", and the first paragraph contained"convert PDF" in bold.>From an indexing standpoint the page spoon-fed meaning toGoogle, and obviously there was a wellspring of PDF softwareadvertisers for Google to find in its database. A match (or fivematches to be exact) made in heaven!Similarly, pages offering FTP software and an Outlook add-inreceived highly relevant companion ads. Again, words on the pagewere sparse, but page title and paragraph text contained theobvious words FTP and Outlook respectively, and Google AdSensetook the bait.The three pages mentioned above offered essentially singleconcept offerings. PDF. FTP. Outlook. No confusing multiplechoices.When analyzing the page which offers Lightning Navigator, ahotkey shortcut software with multiple features, AdSense pickedone feature, screen capture, to orient 3 of the 5 the companionads. Interestingly, screen capture is listed seventh on the listof product features. It follows six other features which wereall keyword-optimized but ignored by AdSense.>From previous research, I recall that keywords pertaining toscreen capture such as "print screen", "screen shot", and"screen grab" receive many more clicks per day than otherfeatures such as "automatically create email" and "internetshortcut".Apparently in this example, AdSense was quickly able to selectthe key concept for which it had the most ads to apply, and thenthrew most of its ad eggs in this basket. The interactionbetween page and AdSense now becomes more interesting. Inventoryof relevant advertisers becomes a factor in selecting keyconcept. That makes sense. You can't post an ad if it's not inthe queue.The non-screen capture ads on the Lightning Navigator page areas follows: 1 for shortcuts (highly relevant) 1 for surveillanceequipment (huh??)I have no doubt that there is a reason the surveillanceequipment ad appeared, but it was not visible to me in the textof my page, the ad itself, or the page which the ad linked to.Mystery abounds on this one.If your eyes are not bleary yet, stick around. There is more totell.A sizeable portion of the Poingo website is the article section.Here I publish articles about small business and people,processes and technology in the workplace.The articles were written without use of a keyword suggestiontool. They are written in 100% non keyword optimized English.What did Adsense do with these verbose index-elusive rants?To appear scientific - after all, somebody might actually readthis - I developed a down-and-dirty rating scale. First Icounted the number of relevant ads (of 5 total) per page, then Imultiplied it by a subjective relevancy score scaled 1 through5, where 5 is "frickin' good" and 1 is "obscure at best."Therefore a page score of 25 (5 ads x relevancy score of 5)would be a top score ("AdSense, you're seeing into my verysoul") and 0 would be ("We never talk anymore, You don't evenknow me(sniff)"). Here is the scoring: Chart showing AdSense AdRelevancy for Articles AdSense scored an average of 10.5 out ofa possible 25 on these wordy, interesting but non optimizedarticles. Yet in 7 articles out of 20, Google scored the coveted"frickin' good" appellation. 35% of the articles were"understood" with high accuracy.Beyond that, there was a chasm of irreconcilable differencesleading ultimately to the vacuum of deep space. What does itmean to us little folk waving our flags and trying to getnoticed on the web?Keep your message simple and clean, boiled down to one or twokey concepts on a page. The spiders want to understand us butthey are kinda dumb. At least that's what Matt says.For charts and data:http://www.poingo.com/ART-think-like-google-with-adsense.htm
