UTF-8 (8-bit UCS/Unicode Transformation Format) is a variable-length character encoding for Unicode. It is the preferred encoding for web pages.

Document Standards

X-UA-Compatible

Meta Description

The description attribute provides a concise explanation of the page content.

Open Graph Protocol

The Open Graph protocol enables any web page to become a rich object in a social graph, a open protocol supported by Facebook

Twitter Cards

Twitter cards make it possible for you to attach media experiences to Tweets that link to your content.

Cascading Style Sheets

Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in a markup language. Its most common application is to style web pages written in HTML

Canonical Content Tag
