Hi Guys just wanna ask if some of you ever notice/experience that some of your ads in msn don't appear. I have experienced this problem since I joined msn adcenter. Sometimes what I do is search for my ads in msn using of course the keywords that I bid in but I still find out that I have no ads showing for some keywords that I bid in. I have over a thousand keywords for one campaign and its pretty hard to keep track of them but I only experience this in msn.

anyone know the answer to this? I have asked msn support about this but they seem to find my ads whenever I complain. I don't know if its just my eyes or something magical happens to the ads.
