So in the past month, I can see huge CTR Drop.
I research what can happen, and I saw that on my websites(i got many) I can see that one ad has not shown every time. it Collapse ad unit, or otherwise show blank space.
i was not sure if this problem with my website or Adsense so I go to the setting and use the "if there's no available ads" option.
i add an image that will appear when there no ads available .
and on that ad spot, i saw the image to many times, while on the same page on another spot i can see Adsense ads working well.
How can I solve that?
