I have made a new layout for my site with wallpaperscript, now i see this ads on my gallery's, 1 block is showing the good words that goes with the wallpapers i have there, the other one not. My question is this normal ,or does google dont want to have more ads on the gallery. This happens to all gallery's samplle here http://www.tws3d.com/luxury_yachts-desktop-wallpapers
I think that happened because one of the google adSense ad code was placed within an IFRAME I am not sure, but I think the one that was placed within an iframe is the one that showing related to "wallpapers" keyword. An the other adsense block that is showing related to "yachts" is because your title "Luxury Yachts wallpapers". So if you want the other adsense block showing related to "wallpapers" keyword, then put it within an iframe or change your title. Again, I am not sure about this, so just try to remove one block and see what happens. And please make sure to check that it is not against adsense TOS to put adsense code within an iframe.
Google gives you ads relevent to your content only if buy mistake if you have given some other keyword " other then wallpaper" it will show ads for it also.
