Could be relevant for optimizing a site for Adsense revenue

I have a page C which is not about a very specific topic. Adsense understandably has difficulty finding relevant ads.

I just noticed this: when I navigate from page A to C, i see mostly ads on C about topic A. When I navigate from B to C, i see ads about B.

Is this how Adsense works? Do navigation paths that visitors choose influence the selection of ads?

This may be relevant for optimizing a site. For example, on a page with relevant high performing ads, outgoing links (to other pages of your own site) may be as relevant as incoming links (bringing visitors to the high performing ads).

(I'm not an expert, but.....) If Google Adsense is "contextual advertising", then the ads that will appear on any page will be relevant to the content of the page, (on the presumption that and advertiser has placed an ad with Google relating to the subject of the content on that page) - and specifically to the content around the Google Adsense javascript, i.e. where the advert is placed.

arrowman, very interesting points.

This is certainly logic from Googles' point of view: "if I can't really understand this page, let's see the previous page the guy visited".

Yet another use for the javascript referrer issue that was discussed here:

[webmasterworld.com...]

(see my comments on page 3)

They may be using 2nd level referer for that frox, I don't know.

My pages A, B and C all have Adsense on them, so G could conceivably follow visitor click paths with a cookie or IP & timestamp heuristics.

"We just served you B, you're now on C and we don't know what to serve you there, so we'll give you B again".

It seems to make sense. I just never noticed it before.

That depends on the concept of "context".

Context is not necessarily just "this page" (the ad's context). It can also be:

  • other pages on this site (the page's context)
  • other pages recently viewed by this visitor (the visitor's context)

    Just so we all know - I've asked Google to verify what they mean by "Contextual Advertising", and I shall post their reply here.

    The behaviour Arrowman describes definitely happens on my site and has done for some time.

    And, as if by magic....an answer form Google arrives....

    "....To clarify for you, at this time AdSense targets ads based on overall page content, not keywords or categories.

    ...we recommend including more text-based content about topics on your site, (edit:as opposed to pictures), to assist our crawlers in gathering information about your pages and determining relevant ads to display. The ads displayed are on a page by page basis. Complete sentences and paragraphs are helpful to our crawlers in determining the content of a page...."

    So there you have it. It solely depends on the page content of the page where the Adsense code is placed.

    The answer from Google is not very precise, send2paul. I don't think it rules out a "pages viewed" factor. And if it does, I tend to not believe that answer :-)

    Sure, it's evaluated page-by-page. But when a page gives little clues, why wouldn't the Adsense machinery reuse a previously selected set of ads? It's both logical and efficient.

    Ha - whatever you want arrowman :) - I half expected that reply.

    Google also didn't rule out Alien Abduction of clicks as well - does that mean it's possible also ;)

    No, it just means that Alien Abduction of clicks, division by zero, moving faster than light etc. is not deemed impossible by Google's answer.

    Browser history can't be accessed in that way. Yes you can use javascript to say things like "go back 3 pages" but you have no idea what that page is/was since you can't access it. In short, there is no way for Google to know which pages a person previously visited before your site.

    We weren't talking about browser history, limitup. You may want to read the thread :-)
