Adsense ad disappearing

Hello,

On my website http://www.iwatchsp.com/ my square ad under the chat on my homepage always dissapear after it loads. But If I go on any other page than homepage the ad loads fine. I don't know if its happening to you guys but what could cause this?

Thank You

 

This normally is due to no keyword match on your homepage
You might need to make some changing or add some content/keyword, or you might try to change the placement to solve this problem

 

If i go on a page with almost 0 content/keyword, I still see an ad.
This is what I dont understand, but Ill try to move it.

 

There is no content on your page ..
copy paste a text and the square will appear ..

 

Ya but if I click on a season

example : http://www.iwatchsp.com/page/season-14

It's the same content but I always see an ad, what's the difference?
Problem seems to only occur on homepage

 

I tested and removed the ad in my header and now the ad which was causing problems in the sidebar always appear correctly. It's like if google already detect 3 ads (max ads on a page) and decide to block one. I'm confused why this is only happening on my home page. Going to sleep, hope I can find the answer tomorrow :/

 

this disappearing of add happen due to lack of content and less keywords

 

I added some contents just to test for 10 hours and its still doing the same.
There's a conflict with my ad on top and my ad on side, it's one or the other that appears (if I remove 1). But it's just on the home page, im really confused ><
