Kw ranking time ?

Hey, I just concentrated on finding a low competition kw and was able to find one with 1300 monthly searches and a Kw difficulty of 31 on MOZ. Its a buyer kw, any thoughts on how long it might take me to rank in top 10 ?

I know that ranking also depends on Seo, content, backlinks and many other things, Will put my best effort on every part just want to the estimated time If everything goes right.

Thank you.

It can rank super fast, within days or it can take a long time, months if you do it poorly.
Put in work and you should be able to rank pretty fast.

Appreciate your reply, I'll start writing the content.
