What is metadata?
Metadata is data about other data. Metadata provides information which can be descriptive, structural, or administrative. Metadata is used in the discovery, identification, categorization, and management of data. Common web metadata is OpenGraph and JSON-LD metadata.
Why is metadata important?
Metadata lets your site talk to other systems like search engines and analytics tools. For SEO, metadata is required to perform well and look good on the SERP. For analytics, metadata enables data drill downs and investigation that would not otherwise be possible.

title tag, the
description tag, JSON-LD structured data, OpenGraph
og: tags, and Parse.ly meta tags. Search engines and Parse.ly then read these meta tags for their systems.
