Would becoming a NASM certified nutrition coach help my healthy food blog not be hit?

I am not sure what Google would see as legit or not when it comes to giving general nutrition advice. I know since the HCU you are not supposed to advise anything health-related unless you are somehow qualified. But is getting reviewed by a RD the best way? Getting some kind of nutrition cert is something I've wanted to do for a long time anyway just for my own education, not necessarily to become a coach. But now I am hoping it would help my blog's legitimacy. Would it? Looking between NASM and Precision Nutrition Level 1.
