My own experience is that I would skip it but not because it is an possible ad. Especially if I'm looking for a product I will look at the ads, sometimes the ads are better than the actual result. But there is a problem with the SERP, and that is that the result under the ads (if any) is sometimes a related sub search. So if i'm looking for some thing scientificy it will show me some sub search of Google scientific results. Or if I'm searching form some thing that has been in the news recently it will show me some Google news results. Now unless I'm looking for papers or news I will skip over it. Since it shows your face next to the link it looks like an news sub search result or indeed a blog result.
