Hello, I am new to Adsense and I have a newly active account (5days). I have noticed that some pages doesn't display ads at all, why? One 160 x 600 - Wide Skyscraper banner is in the sidebar which should display ads everywhere, but it doesn't , it shows in 70% of my 1660 pages (nightclubs in Italy related) , what is the criteria? Example: This one shows ads: http://4ella.com/2013/05/open-gate-civitanova-marche/ This similar one doesn't: http://4ella.com/2013/10/luna-lulu-night-club-porto-dascoli/ index.php page here http://4ella.com doesn't show banner in sidebar too. All pages are original, not copyrighted, created by this form: http://4ella.com/forms/segnala-locale/ There are many pages like this which doesn't display anything, but to be more clear I will give only this example, what's the difference between those 2 pages? Some words in articles are banned? Or one page is slower than another one? I have no idea what is wrong and if this is normal and if can I be in trouble in future with Google policy.
I have noticed that http://4ella.com/2013/10/luna-lulu-night-club-porto-dascoli/ page at this moment started to show the ads, but some others including index.php page (I thought that home page should be most interesting for google) doesn't, so myshufflemix let me better understand, who decides if for example on my main page http://4ella.com/ will be some ad or not? Google who is controlling my text on that page or who? Advertisers ? How do they do that? What should I do to do not have a blank space on the main index page sidebar
