Recently my adsense revenue got reduced while there is not much change in traffic. So, I am exploring various ways to fix it. Currently I am using adsense in various websites from my single adsense account. So, I thought of creating targetable Adsene Channels for each site separately. I had created separate ad unit specific for my Software Testing Tutorial site qtpbook.com around 30 minutes back. But till now ads are not showing from this new ad unit. How much time it will take to see the Ads? Previously , I used to see the ads in 2 or 3 minutes. Why it is taking this much time? Is it common for targetable ads? Or is it specific to my site qtpbook.com alone?
Thanks for all your replies. The ads are appearing now. Let me check the adsense reports in few weeks to know whether the "targetable ads" help to increase the adsene revenue.
