adsense – & # 39; Precious inventory: no content & # 39;

I have recently started a food blog. I had almost 10 messages when I applied for google adsense and I was rejected.

Here is the message I received: "Valuable inventory: no content. We found on policy violations that prevent the approval of your site. As stated in the rules of our program, we may not serve Google ads on pages or apps that are of little or no use and / or excessive until changes are made. "

Could someone explain what that means?

I have content that is mine, privacy policy, contact us page & seo. This is my blog: Check it out and tell me if I have something wrong.

I am still learning to manage a blog. I'm adding more messages before reapplying. Thanks in advance!
