I've recently added some javascript to a majority of pages that auto generates content. After about 2 hours it seemed the revenue /cpc / average went way down and hasn't gone back up since. I haven't changed anything else on the pages except for adding this script.

Over the course of many years I've never seen this kind of drop in rev. Has anyone else seen this or has something been tweeked on Googles end?

How much of your page's content is the javascript generating? The adsense bot (and bots in general) does not execute javascript, and therefore, will not be able to target the ads for your site properly if too much of your content is being generated this way, because it can't see it.

Look at your site with a text browser like Lynx. That's what Google sees.

It would be easier to turn off Javascript in your browser.
In Firefox click the Tools menu, then click the Content tab and unselect the Enable Javascript box.

Actually, the same amount of content is still on the page. It was an over all devaluing, not just the java pages. Pages that were once doing well are now generating a lower amount of revenue.

So to answer the question, 1-5% of a page is generated content. The rest is text.

maybe the script slows down your page load.
it is sometimes easy to forget that when you're using broadband. even if just it adds a second you could get a rise in people bouncing out without waiting for it to finish.

Yes, I was gonna say that, but the rest of my sentence was "that's what Google sees". To get a true representation of that, you need to do something like lynx. If you turn off javascript, you can still see images, flash, etc. All things that can contain content that bots can't see.
