META Robots and META Refresh

META Refresh 
Syntax: < META http-equiv="refresh" content="0;url=http://newURL.com/">

This HTML META tag also belongs in the Head tag of your HTML page.

The META Refresh tag is often used as a way to redirect the viewer to another Web page or refresh the content of the viewed page after a specified number of seconds. The META Refresh tag is also sometimes used as a doorway page optimized for a certain search engine, which is accessed first by users, who then are redirected to the main website. Some search engines discourage the use of this META tag, because it is an opportunity for webmasters to spam search engines with similar pages that all lead to the same page. In addition, this also clutters the search engines databases with irrelevant and multiple versions of the same data. Try to avoid doorways and redirects altogether in your Web/blog  building.

META Robots
Syntax: < META name="Robots" content="INDEX,FOLLOW">

The robots instructions are normally placed in a robots.txt file that is uploaded to the root directory of a domain. However, if a webmaster does not have access to /robots.txt, then instructions can be placed in the Robots META tag. This tag tells the search engine robots whether a page should be indexed and included in the search engine database and its links followed.

The content of the robots meta tag is a comma separated list that may contain the following commands:

ALL also INDEX,FOLLOW -- there are no restrictions on indexing the page or following links; NONE also NOINDEX,NOFOLLOW -- robots must ignore the page; a combination of INDEX, FOLLOW, NOINDEX, NOFOLLOW -- if you want a search engine robot just to index a page but not to follow links, you should specify 'INDEX,NOFOLLOW', if you want it to follow links without indexing the page, you should instruct robots as 'NOINDEX,FOLLOW'.
