Definition - What does Meta Refresh mean?
A meta refresh is a method used in HTML to redirect Web users to a new page from an old address. Using the HTML meta-element with the refresh command can accommodate this type of change, which can be extremely important for maintaining Web traffic for a given domain or project.
Techopedia explains Meta Refresh
In general, a meta refresh is only one of many meta-commands that provide top-level identification for an HTML page. These include meta-description and meta-name structures that help to show authorship of a page and identify it with descriptive information that will aid in search engine optimization and other situations.
The World Wide Web Consortium has released certain conventions related to the meta-element. For example, there is the consistent standard that a meta-tag goes inside of a head element and that metadata is always passed using the name/value pairings.
