Now it seems some pages have immediate ads. In other words pages that never existed before have immediate ads. I think I recalll seeing this at the beginning of AdSense but for us at least recently it was more wait a while then an ad would appear.
It does not happen for all pages even though they seem very similar.
Anyone else see this?
Perhaps it depends on how busy the 'bot is - in some cases it may have zipped through before the ads were loaded.
An alternative explnation may be that generic ads are produced if new pages are uploaded in a highly populated directory.
The ads in the book review definitely weren't general "site theme" ads like the ones I might have expected to see--they were matched to specific keywords on the page.
We can't even get it to revise ads on end of month changes anymore, including revising ad sizes to attract it. Send it our way for a bit please.
And we have even more pages that are targeted to the site, not to the actual page - not even if we change the ad format several times. Some pages are just sooooo stubborn! Thankfully, our site's main topic attracts a lot of advertisers and good EPC.
I'm convinced that the google bot comes around more often the better your PR. I wonder if there is any such pattern with the media bot.
Could be, but if there is, it would make more sense (from Google's point of view) to base the Mediapartnerbot's visiting schedule on revenue or impressions, not on PageRank.
Then I set up a test site on this domain (www.domain.com/testsite/), also using adsense code. However, this site was not about widgets at all, but it was still showing widget related ads, the one relevant to the main site.

Mediapartners bot spiders a page on my B2B test site within a few minutes after some visitor views that page. Sometimes 1-2 minutes, other times it takes a bit longer.
On more "mainstream subject" pages which receive a much higher number of visitors/day, I noticed that it would take a bit longer.
All pages are static, with Modified- http header.
On the other hand, I *think* that Mediapartners Googlebot is less eager to spider pages I view myself, from my own IP (that I check Adsense account with). Just my impression.
Edit PS: Just to add that I had a look at my Adsense monitoring script (I only check Adsense 2-3 times per week) and see MANY new advertisers. Back in April, 40% of all ads were "generic", e.g. BizRate. At this rate of change, I think that in 1-2 years only the bigger advertisers with big budgets will be able to advertise, just like few companies can afford to advertise on national TV.
Now usually, I would have passed it off as themed ads. Yet this site was about something COMPLETELY different than my other sites. ie. if all my other sites were "sports", this one was about "knitting" (exampled keywords ;) ).
So I thought hmmm, perhaps mediabot had somehow been to other pages in the site, and they were already showing themed ads for the site, but that wasn't the case. This particular page mentioned something seemingly off-topic to "knitting", such as "ice cubes". And lo and behold, the top ads in a 5-ad skyscraper were "ice cube" ads.
There is no way mediabot could have guessed that without seeing the page, in fact, it is probably the only mention of "ice cubes" on any of my pages on any domain running AdSense, yet my logs showed mediabot there within about a second of my viewing the page, and extremely targeted ads appeared instantly.

I think that will depend a lot on the topic. Bids for mass-market and big-ticket items are likely to become much more expensive, but bids for more obscure goods and services won't necessarily rise significantly because there won't be enough bidders to create more demand.
I have seen a site one day where you could put in a url and then see type of ads you'd get. This was a couple of months ago, before swiches in targeting. Perhaps they've implemented this again for pre spidered pages?
Definitely not with the example I used.

You are most likely right. I think it might be more CTR than total clicks as I have a niche topic and it appears to be checked almost instantly.
It was as if the mediabot was actually spidering, once called to the index page it seemed to have found the other pages before anyone (myself in this case) had clicked through to them.
They were extremely targetted and unique to each page, so not generic run-of-site ads.
Is it possible that mediabot proactively spiders through the site looking for other pages with adsense on them, I thought it was generally initiated by first visit to the page.
