Hi, I have a blog at blogger.com. When I priew the my blog while editing there are three adds. but when I actually view the add in a new wibdow(not while editing) there is only one add which is not even relavent to my blog. Please I require your help. my blog url is-http://idiot-blogger.blogspot.com/
Your blogs main keyword is "idiot" which is repeated several times. And do you know what google says about it?
The reason of PSA ads on your blog may be the following as well. Wait few days. If still PSA ads displays on your site then remove the word from your blog.
No content in your blog. All are video's and only few words about that video. Thatz y no ads in you blog. Add some more content about the clipings and also remove the words idiot.
Write 2/3 lines about each vedeo. Don't use the word "idot". You have same word in blog title (idiot-blogger.blogspot). So if possible delete this blog and start another blog with same content.
it doesnt matter whether you are a newbie or a webmaster. you can always add fresh content(i think anyone can do it,since no technical knowledge is required). so just update,add content.also try to focus the ad on some target.
