Informational meta tags


Informational <meta> tags are those that provide <<extra>> information to crawlers but are not visible to normal website users.

These types of tags help the crawler to understand more about the information that a website is offering, whether about its content, the company that owns the page or its creator, such as:

< meta name = "copyright" content = "company name">
< meta name = "language" content = "ES">
< meta name = "revised" content = "Sunday, July 18th, 2010, 5:15 pm" />
