Ads not appearing on some Blog posts

I have a WordPress blog on which I am using Google Adsense but I have noticed that on some of the posts I don't see ads while on other posts there ads are appearing.Please tell me what is problem ?

Also why my CTR and CPC are very low ?

For example no ads on this blog post : http://pakistanhumara.com/safar-ki-dua-for-traveling/

While this blog posts have ads : http://pakistanhumara.com/pictures-of-islamabad-united-players/

 

first one has foreign characters in post, second doesn't

try removing that

 

I go this from Adsense official help website

Most posts should have at least 400-500 words of text, and it should be fully original text in a supported language. The post you quoted which does not show ads is some kind of prayer in three different languages, but nothing is original.

As for picture posts, those should not be on a blog with Adsense at all. If you did not take the pictures, you are violating copyright. And the majority of any post should be text, even if you use some pictures (of your own) to illustrate it.

 

if they flagged pages as violating policy, you would get a warning in adsense console
