META tags are descriptive & informative HTML tags which are (or which can & should be) encoded into each web page of a website. They give search engines a quickly accessible means of performing initial analysis and categorization of a website, which the search engines then add to the various other bits of information they glean from the web page content and other aspects of a web page / site.
Some META tags are of greater importance / usefulness than others, and it's worthwhile to learn which are of value, and how to correctly incorporate them into web page code.
