Keywords I'm Trying To Target Does Not Appear In GWT

Hello Everyone!

I'm new to SEO and I have an affiliate marketing site which is about 1 months old. The issue I'm facing currently is that the long tail keywords I'm trying to target are not appearing in my GWT Search Analytics.

My article is about 3000 words. I have all the basic on-page SEO done. I've sprinkled long tail keywords I'm targetting and there are outbound links linking to authority sites. However, the keywords are still not appearing.

My question is:
1) How long does it normally take for the keywords to appear in GWT Search Analytics?
2) What am I doing wrong?

Would love to hear from experts so I can learn more about SEO. Thank You!
