Key words meta tag placement

Site URL: http://atopedancefitness.com

Hello

I’m new here, I’m creating my website on my own, and I would like to introduce a meta tag with description and keywords into the website, but I can’t find anywhere in the website building about meta tag, or keywords section so the SEO Pick it up a bit better. 
 

could anyone let me know where do we introduce this meta tag code ?

I’m not sure if it needs to be introduce in the code injection part or somewhere else 

Thanks 

You can insert meta keyword to Code Injection Header (Home > Settings > Advanced > Code Injection > Header)

Thanks

The old meta keywords field is sometimes missing in most modern CMS systems because it's no longer used by Google as a ranking factor. I think Wordpress still has the field, although the Yoast plugin will kinda yell at you if you use it. Because of this, most people stopped using meta keywords since all it did was tell your competitors what terms you were targeting.
