New dynamic site - getting lots of PSAs

Do I have to wait for a crawl?

[whatcartridge]

I have a site, been up for about 3 months, with about 20 dynamic article content pages which show the Adsense ads beautifully, and about maybe 50,000 (?) pages with dynamic content (i.e. which thingummybob fits into which whatchimacallit) which don't show Adsense correctly. So the dynamic content is basically a list of thingummybobs with a heading being the name of the particular model watchimacallit, there is not much content there. The site has only been shallowly crawled by Google and only 12 pages appear on the SERPS.

When a visitor first views a dynamic page, the horizontal Adsense banner which is between the whatchimacallit and the list of thingummybobs is empty and the vertical skyscraper in the left hand column has a PSA. I thought maybe there was not enough content on the page or there were not enough advertisers available, however...

If you wait a few minutes and refresh the page, the ads appear (and they are relevant). If the page is revisited the same or next day, the ads usually appear, sometimes not. If the page is not visited for a few days the ads disappear again and you need to refresh etc to make them re-appear. Our most popular pages, ones that have been viewed many times, show ads permanently.

I tried adding a bit more content to each page, and section targetting, but both didn't make any difference.

By the way, the pages don't have a session ID appended to the URL! They do have up to 3 parameters in the dynamic URL (I know, I know, that's bad)

Has anyone had an experience like this? I know it sometimes takes the Google Mediabot up to 48 hours to get to know a page, but I don't know why the ads disappear again?

Will ads appear all the time once the site has been fully indexed by Google? Or is there a seperate crawl by Google Mediabot?

what language is about your page?

i've no experience with waiting for crawling my site. relevant ads are showing from first starting day. session ids, dynamic pages aren't responsible of showing PSA's.

have you tried with adsense preview tool?

AdSense crawlers cannot derive meaning from images and dynamic content such as Flash, for example. Does your site have any HTML text-based content? If not, you might want to try adding sentences or paragraphs to your page to help our crawlers serve relevant ads.

I also think the URL per se is very important so do yourself a favor and learn some Mod_rewrite which will be very good in the long run.

I looked at your site and see exactly what you're talking about. When I was there, perfectly good pages with good text served no ads at all, just the blank space. Looks like the ad code is ok, too; at least it appears to be the same on the pages that get ads, and the ones that don't.

I looked at your site, because I noticed very similar problems a long time ago. I now make it a habit of every month or two visiting all the dynamic pages on my site; if I wait too long, they get no or generic ads on the first visit, then targeted ads the next day.

Thanks for your input people.

My site is in English. If I use the Adsense preview tool when I first load the page, it says there are no ads for the page. If I reload the page a few times, the ads appear and the preview tool shows lots and lots of ads for all countries.

I have no flash or anything like it,just straight HTML. I tried adding a good 10 sentence paragraph of text to each page but it made no difference. I had already read the page you referred me to, thank you.

Good advice about the mod_rewrite. I will be doing that.

How many pages do you have on your site? I hope I don't have to click all the way through my site once a month!

I tried the Adsense code on another dynamic site I have (different content but similar setup and layout) and the code worked fine, showing relevant ads first time every time. The diffrence is that this site has had all pages crawled by Googlebot and appears in the SERPs.

Seems I have to wait for this new site to be crawled by Google and indexed before it will show ads correctly. Would this be right Adsense Advisor? If so what a pain, as it has been up for a couple of months now and has alot of traffic from a few links but abysmal CTR and CPM. It has 14 pages indexed in current Google SERPs and only 2 pages in the Big daddy SERPs.... aaaaarrrrggghhhh!

Well, I ensure that my highest value and rarely-visited pages are accessed.

The pages that people visit regularly aren't the problem, it's the ones that get a visit once every month or two... you can BET that I don't want any visitor to see a PSA. lol
