If you have hard coded meta description and keywords on all your pages, it is better SEO practice to REMOVE it than keeping it.
<meta name="description" content="Your description goes here" />
<meta name="keywords" content="your,keywords,come,here" />
It’s better to define those lines for individual page since they are different for each page.
If you can’t maintain or have no idea what to be included in this two meta field, remove it for better SEO.
