Normally when u set up an adsense, you will be given 3 options under the "Alternate ads or colors" There are, "Show public service ads", "Show non-Google ads from another URL" and "Fill space with a solid color" Then I selected the "Show non-Google ads from another URL", and display another html page when there is not ads for that particular ads block. However, the displayed html page containing another adsense block. will it show up or not? I think maybe there won't be an ads since the original ads never shown with relevant keywords or something. Hence, I changed the original ads to display the image ads only, so this will let the second have chance to display and with a relevant keyword. But I think this is not working, because the second ads block always blanked. However, there have some impressions when I check the report. Anyone know more for this complicated situation? or can view the second ads block at my site? check my sig to understand what I trying to explain and thanks for the read
