Should I be worried? Completely organic traffic, no forced clicks or anything too blackhat. Ad coloring match to the sites well, but still IMO anyone should notice that those are just G00gl3 Ads. Ad placement is done manually and is done with thought. But some of the ads are placed quite close under the nav menu, but its still easy to navigate - is that ok? Some of the ads are also under heading "Keyword Links" and only after the ad the real links. This is what Ive seen on many sites (Heading - Ad - Text), but is that ok with big G?
