the showing or not showing of the ads depends upon many factors
content or search results
The amount of money you put...as on search pages only some positions are available
You can check the status if your ad is being shown for particular keyword by using tools present within adwords
this will tell if ads are shown in particular country or not
hope this helps
I tried the no. 1 for some time and got decent clicks and CTR?
After I saw various postings here, I started the no. 2 and I am not getting the same clicks that I used to get it.
I am going crazy. Please , help me on this.
