I am new at all this stuff, so I figured I would ask the pros.
I am attempting to "Monetize" my site (Leenkz.Com) and I have started by adding Adsense, I had no problem adding a html block and inserting the adsense code into it, but the problem im having is the following: At the Adsense site, it says that you can now have up to three adsense thingys in each web page, but, when I add a second html block to my postnuke, and I add the adsense code, nothing shows up in the block. Is there an issue with Adsense and php pages, or am I doing something wrong???
It means there aren't enough ads to fill the second space yet. Give it a day or two. You can always put an altad in so that the space is used for something that benefits you when there are no ads to show.
I have leaderboards that should show 4 ads at a time and on some of my sites there are consistantly only 2 or 3 and sometimes only one ad shown. It all depends on the AdWords inventory for your keywords.
