Meta tags are HTML tags that describe your page content to search engines and website visitors. The meta tags appear only in the page’s code, and anyone can check them via a website’s source code.
Meta tags, such as the meta title and meta description play important roles in a website’s SEO plan because they contain keywords and phrases that describe a page’s content. Without it, web sites will not be properly indexed or showcased to users in search engines.
Meta tags can be viewed by selecting View/Source from the menu of a browser.
There are four variations of Twitter cards:
Twitter Card tags are in the format twitter:tagname.
|twitter:card||The type of Twitter card that should be displayed using the tags|

|twitter:title||The title of the content, e.g. "A Blog Post"|
|twitter:description||A brief description of the content|
|twitter:site||The Twitter account associated with the content|
