This tutorial is all about HTML Meta.
Meta tags are invisible units that are working behind the scene to supply information for search engines that present that data to any potential users that came across to your site by the use of a search engine.
Search engines give direction of the web which help users navigate from one site to another. When you use a search engine, the description meta tag will be immediately seen in action.
Take note that Meta elements should be placed inside of the <head> element to be recognized by the web surfers. It requires the name and content attributes to work together to present your web page precisely.
