No Ads Showing on new pages

[ElvisFan]

In the last month or so I have noticed that whenever I create a new page/article to my 300+ page site - no ads show up at all?! Even a week later NOTHING?!

In the past whenever I updated my site ads appeared almost immediately.

I have a niche site and my new articles are in keeping with the exisiting theme - so I can't think what the problem could be - my only thought is that adsense has run out of ads?

I have tired deleting ads from other low hit pages.
I have tired tweaking my mega tags
I have tired re-editing the content
I only ever have one ad per page (250x250 or 300x250)

But alas to no avail - so any suggestions would be most welcome - thanks

Most likely the ad inventory is limited for your niche. If you feel that is not the case then an email to Adsense would be a good idea. They normally fix this kind of issue almost immediately if the mediabot is not picking up relevant keywords on your pages.
