Adding meta tags on Google Sites – SEO

Apologies if advance if the questions here are too basic as I am new to web development and SEO. I have a website built on google sites and trying to improve SEO rankings using meta tags. I have figured out how to write up a meta tag. For example, the following:

<meta name="title" content="pomorobotics.com">
<meta name="description" content="Unsure how to work with robots? We can help. Specializing in robotic systems integration, end of arm tooling and industry 4.0 solutions. Get in touch!">
<meta name="keywords" content="Robots, Robotics, Collaborative, End of Arm Tooling, End Effectors, Automation, Systems Integration, Digital Twin, Digitisation, Industry 4.0, Solutions, Turnkey, Robotic Solutions, Engineering">
<meta name="robots" content="index, follow">
<meta charset="utf-8">
<meta content="IE=Edge" http-equiv="X-UA-Compatible">
<meta content="initial-scale=1, minimum-scale=1, width=device-width" name="viewport">
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="HandheldFriendly" content="true">
<meta name="MobileOptimized" content="width">
<meta name="twitter:title" content="pomorobotics">
<meta name="format-detection" content="telephone=no">
<meta name="format-detection" content="address=no">
<meta name="application-url" itemprop="url" content="www.pomorobotics.com/home">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="language" content="English">

Google Sites only gives me the option to Embed code, would the meta tags be functional if I was to insert this script customised per page? I am thinking of adding the code as top of the website as possible – either adjacent to the Title or heading blocks. I’ve attached an image showing where I have the meta tag script embedded as a block
