Should I go after high or low volume keywords?

I have been working on my SEO strategy for my blog for a few months now but wondering how to go about my keyword research.Should I go for high volume keywords or low volume keywords? Currently I rank well for very low volume keywords but I'm barely getting any organic traffic. If I try to rank for higher volume keywords, I am competing with seasoned blogs with tons of backlinks and high domain authority so I don't stand a chance. For reference, my niche is blogging about low carb recipes with African flavors and spices and my blog is a little over a year old.What is the best strategy to use? Thanks! via /r/SEO http://bit.ly/2Ict0kh
