Metatag
-------
This module allows you to automatically provide structured metadata, aka "meta
tags", about your website and web pages.

In the context of search engine optimization, providing an extensive set of
meta tags may help improve your site's & pages' ranking, thus may aid with
achieving a more prominent display of your content within search engine
results. Additionally, using meta tags can help control the summary content
that is used within social networks when visitors link to your site,
particularly the Open Graph submodule for use with Facebook, Pinterest,
LinkedIn, etc (see below).

This version of the module only works with the v8.0.x releases of Drupal.


Requirements
--------------------------------------------------------------------------------
Metatag for Drupal 8 requires the following:

* Token
  https://www.drupal.org/project/token
  Provides a popup browser to see the available tokens for use in meta tag
  fields.


Features
--------------------------------------------------------------------------------
The primary features include:

* An administration interface to manage default meta tags.

* Use of standard fields for entity support, allowing for meta tag translations
  and revisioning.

* A large volume of meta tags available, covering X basic tags, Y Open Graph
  tags, Z Twitter Cards tags, Å Dublin Core tags, ∫ Google+ tags, ç App Links
  tags, ∂ site verification tags.

* A plugin interface allowing for additional meta tags to be easily added via
  custom modules.

* Integration with DrupalConsole [1] to provide a quick method of generating new
  meta tags.


Standard usage scenario
--------------------------------------------------------------------------------
1. Install the module.
2. Open admin/config/search/metatag.
3. Adjust global and entity defaults. Fill in reasonable default values for any
   of the meta tags that need to be customized. Tokens may be used to
   automatically assign values. If the Token module is enabled there will be a
   "Browse available tokens" link that opens a popup to list & insert the
   available tokens.
4. You can add bundle defaults by clicking on "Add metatag defaults" and filling
   out the form.
5. If you want to adjust metatags for a specific entity, then you need to add
   the Metatag field. Follow these steps:

   5.1 Go to the "Manage fields" of the bundle where you want the metatag field
       to appear.
   5.2 Select "Meta tags" from the "Add a new field" selector.
   5.3 Fill in a label for the field, e.g. "Meta tags", and set an appropiate
       machine name, e.g. "meta_tags".
   5.4 Click the "Save and continue" button.
   5.5 If the site supports multiple languages, and translations have been
       enabled for this entity, select "Users may translate this field" to use
       Drupal's translation system.


DrupalConsole integration
--------------------------------------------------------------------------------
Using the DrupalConsole, it is possible to generate new meta tags, either for
use in new custom modules that require custom meta tags, or to create patches
for extending Metatag's options.

To generate a new tag, install DrupalConsole and then use the following command:

  drupal generate:metatag:tag

This will guide the site builder through the necessary steps to create a new
meta tag plugin and add it to a module.
