right? I've met this problem my site pages all have two adsense script only the Previous one will appear I'm not sure about this any tips? thanks
Make sure there is enough text on the page so that google can give you varying type of ads and if it's only been a few minutes since you added the code just leave it for a while and check back later.
Two reasons I can think of: 1. G doesn't have enough relevant ad's for the content of your site. 2. You just recently added the code, and your site hasnt been crawled.
Happens to me all the time, sometimes i lob the 2nd ad into an iframe to get around to problem, ruins the look of the site otherwise.
2 things: #1: if you put those TWO scripts into the same table-cell, it might not work #2: the 2nd ads won't appear if you are using preview tools on Frontpage or view the website on the browser if the HTML files are not yet uploaded to the actual server.
