Configure the meta tags below. Use tokens (see the "Browse available tokens" popup) to avoid redundant meta data and search engine penalization. For example, a 'keyword' value of "example" will be shown on all content using this configuration, whereas using the [node:field_keywords] automatically inserts the "keywords" values from the current entity (node, term, etc).

Basic tags
The text to display in the title bar of a visitor's web browser when they view this page. This meta tag may also be used as the title of the page when a visitor bookmarks or favorites this page, or as the page title in a search engine result. It is common to append '[site:name]' to the end of this, so the site's name is automatically added. It is recommended that the title be no greater than 55 - 65 characters long, including spaces.
A brief and concise summary of the page's content that is a maximum of 160 characters in length. The description meta tag may be used by search engines to display a snippet about the page in search results. This will be truncated to a maximum of 380 characters.
A brief and concise summary of the page's content, preferably 150 characters or less. Where as the description meta tag may be used by search engines to display a snippet about the page in search results, the abstract tag may be used to archive a summary about the page. This meta tag is no longer supported by major search engines.
A comma-separated list of keywords about the page. This meta tag is no longer supported by most search engines anymore.
