Question: How To Know Where You Rank For Certain Keywords

Is there a free online tool I could use to see where I rank for particular keywords? I know I'm nowhere near the top of the list, but I 'd like to see where I stand (even if it's position 1,300).

For whatever reason the tools I've tried are saying I don't rank for any keywords, which is weird because I'm writing 2,000+ word articles targeting them.

Maybe it's because the website is only a couple of months old?
