Ads not targetted

What Adsense Support said may be the problem

I started noticing that one particularly important page began showing ads that were targetted to the main theme of my site but NOT to the specific topic of my page. They used to be very targetted to the page's topic.

Contacted Adsense support and they informed me that it was probably because my pages haven't been crawled.

Oooops. Here's where I may have made mistakes.
A couple of months back, I added a variable to my URL string for this dynamically driven page (because I had to) and this probably caused a lot of the pages to go supplemental. According to Adsense support, the change in the URL string also meant that Google understood these to be new pages and have yet to re-crawl them.

Questions :

1. I think nothing can be done about those pages that have gone supplemental, so what's the best way to deal with this?

2. If the problem is that my "new" pages with the added variable in the URL string need to be re-crawled, is there any way to force the Adsense bot to re-crawl them?

BTW, I re-submit my updated sitemap to Google sitemaps every Friday. Isn't this enough to make Google re-crawl the pages? Should I change the priority in my sitemap for this page to force Google to re-crawl?

Making an ad format change used to force a recrawl, although I'm not sure if that is still the case. Worth a try though. Change the size or something.

When someone requests a page that contains AdSense units, it triggers a request from the Google Mediapartners robot. So all you should need to do is make a visit to your own page. You should be able to verify in your site logs that Mediapartners got the page.

Edit: It's possible Mediapartners doesn't get the page *every* time you do. Maybe there's a limit of once a day or something. My pages are infrequently visited, so I see a Mediapartners visit for each of my own pages that I view.

For what it's worth, I submitted a sitemap a long time ago (when all the buzz about them was happening), but left it up on my server for ONLY ONE DAY. That apparently was too long an amount of time as Google spidered the site then and it's been updated by Google ever since. It seems to me that once Google has your sitemap, they don't even need the one that's supposed to be on your server - they just use theirs!

Here's a funny thing...

I changed the priority for the pages concerned to 1 and the change frequency to daily in the sitemap and lo and behold, the ads started being targetted again - for one day. Then it went back to targetting my main theme instead of page topic again. You may be right Play_Bach, once google has your sitemap, they don't need a refresh. I don't know what to do next.

I would expect: in one sense "yes", and in another sense "no". I figure the purpose of Mediapartners is to ensure that properly targeted ads are served. Thus at ad-serving time it will get the page to find out what its content is, especially if considerable time (a day?, or whatever) has elapsed since the last time it saw the page.

As I've heard, sometimes Mediapartners will instead use the cached page that was retrieved by Googlebot, and sometimes Googlebot will use the cached page that was saved by Mediapartners or some other Google robot. That is, Google robots sometimes share their cached pages instead of making an actual request to your site.

I expect Mediapartners places a very high priority on having a current copy of the page due to its business purpose of serving targeted ads in real-time. However, Google keeps its various services well partitioned from each other, so it is not likely that having an updated Mediapartners cached page will help you much with Googlebot. That is, Mediapartners may maintain a very up to date cached page, but it is not likely that Googlebot will check it any more often than it used to, so Google's *indexing* of that page will probably be no better than it ever was, and you would have to wait for any reindexing to repropagate, as always.

Wow... I had to read your post slowly so as not to miss anything! Isn't re-indexing a daily on-going thing? or are we talking about a major re-indexing. If it is, then what is the normal interval for such a re-indexing?

From what I've seen from my stats, Google only spiders some of my pages each day - they don't do the whole site. Once in awhile I'll check the Google cache date for a page to get an idea about when it was last indexed.

They definitely don't visit every page on the web every day. Also, all pages are not treated equally. A high-PR page that changes frequently might get crawled and indexed every day. A low-PR page that hasn't ever changed might not get recrawled for months.

LOL! Adsense replied again. Seems I'm in a different quandary now... they said that the ads for my site's theme were far better paying than the ads for my page's topic and that's why they keep edging out the lower paying topic ads. Well that shut me up.

It would seem that I am doing too good a job optimizing my page for high paying ads. I figure it's that one variable (also a highly searched key phrase) in the URL string that triggers this.

So now it looks like I have two options :

- keep my mouth shut and enjoy the fact that I'm getting high paying ads

- remove my page optimizations for the theme so that the ads target the topic instead (for the benefit of long-tail search visitors who came looking for info on the page's topic)

Waddya think?
