We use drupal and were serving adsense from blocks, which were not cached. All was OK. The block was serving on a story page, which was cached. I mean the page was cached but the block was not.

Few days ago, we decided to serve adsense directly from templates,

Earnings declinded 30 percent already the 3rd day. Don't know if it's because of the change and needs time or serving in blocks that are not cached are better than serving directly from template that are cached.

However, this should not have any effect should it? Aren't adsense codes java based and therefore no effect?

Thank you.
