Hi, I am planning to place Link units ads in line format, just above my list of options (also in horizontal format). Is it allowed by TOS? You may consider that users may miss my menu click and hit by mistake the ads. Hence my question. Thanks.
Clicking the link unit won't get you paid. But clicking the link unit AND clicking on the resulting page will get you paid. So, I think that yes, you are allowed to do so.
The problem is, that the final decision is in hands of google. If they recognize it as misleading, you know what they can do. But this is indyvidual for every page design, so... it depends how you want to do that.
