where and how should I add meta tags in my html code to improve my SEO?

Meta tags belong between the <head> tags near the top of your HTML code.

The tags you definitely want to have are:

Title tag – Not technically a meta tag but definitely to be included, Most important tag for SEO and deifnitely includes your primary keywords for the page.
<title></title>

Description Tag – Second most important tag, use sentences, make a pitch if you can, but definitely include your keywords here.
<meta name="description" content="" />

Keywords Tag – Separate your keywords with commas, or group into phrases, lot of flexibility here and a lot of conflicting advice exists.
<meta name="keywords" content="" />

Robot Meta Tags
Primary Robots Tag – Instructs robots, or search engine software, to include your content in their search index and follow the links on this page to others in your website
<meta name="robots" content="index,follow" />

Slurp No Yahoo Directory description tag – Tells Yahoo search engine to use your meta description instead of a description they find in the yahoo directory.
<meta name="slurp" content="noydir" />

Google bot tag – Similar to robots tag, provides directions to Googlebot. It is not necessary but can’t hurt.
<meta name="Googlebot" content="index,follow" />

Note, the examples above use the XML-style closing tag. Leave out the trailing / if your page is not xhtml.
