In HTML, meta tags are tags placed within the head section of your code that help define the contents of a web page. There are two Meta tags that are generally used to inform search engines of the content on the page.
Meta Keyword Tag
The meta keywords tag is one of several of meta tags that you can insert into your web pages to provide search engines with information about your pages that isn’t visible on the page itself.
Meta Description Tags
As we all know, Meta Description is an attribute within a meta tag that helps describe your page to search engines. Your page likely already contains a meta description. You can find it by right-clicking on a page, and select "view source" or "view page source".
