i have a problem guyz.. i put a sky scraber ad in my blog but it isnt appearing !! what can i do to make it appear?? thx ..
Just wait for awhile. It usually appears within first 10-15 minutes. If not, then you have entered the code incorrectly.
Try clearing your browser cache and try again. Wait for at least 10 minutes after generating adsense code and allow it to display ads.
You need to check your code, wait 10 minutes to update, and possibly clear your scripts/software your site uses cache. Then, refresh the page. Be patient. It's not instant.
