notranslate

For translation of literals on HTML pages, such as those used in forms and tables, see the Literals.com project in Google code.

Examples

<meta name="google" content="notranslate"/> The name="googlebot" Metatag

The name="googlebot" HTML metatag

The googlebot metatag is equivalent to the robots metatag but provides directives specifically for the Googlebot robot and is supposed to be ignored by other web robots, crawlers and spiders.

archive / noarchive
indicates whether or not the page should be archived by Google
follow / nofollow
indicates whether or not Googlebot should continue to crawl other pages referenced in the hypertext links on the page
imageindex / noimageindex
indicates whether or not the page should appear as the referring page for images that appear in Google's search results
index / noindex
indicates whether or not the page should be included in Google's search index

indicates whether or not the description from the ODP should be used
snippet / nosnippet

See http://www.Google.com/support/webmasters/bin/answer.py?hl=en&answer=79812

The http-equiv Metatag

The http-equiv HTML metatag

Default Style

The http-equiv="default-style" metatag specifies the default style sheet for the page. For example, this could be a site-wide template:

Examples

<meta http-equiv="default-style" content="/site-template.xsl ; type=application/xslt+xml"/>

Meta Refresh

The http-equiv="refresh" metatag can be used to refresh the current page at regular intervals or redirect to a different page after a given period of time. The first parameter of content is the time to wait, in seconds. The second parameter is the URL of the next page to be displayed and is optional.

Examples

<meta http-equiv="refresh" content="10"/> <meta http-equiv="refresh" content="0;http://www.ExampleOnly.com/"/>

http-equiv Metatag for Other HTTP Headers

Other frequently used http-equiv metatags for HTTP headers include:

Cache-Control
which indicates how long the page should remain in the client's cache
Content-Disposition
which indicates how or when the content should be displayed
Content-Type
which indicates how the document is encoded, in terms of both the character encoding used and the syntax of the content.
Expires
which is an alternative way of indicating when the content should expire from cache
X-UA-Compatible
X-UA-Compatible is used to indicate to an IE browser which version of the rendering engine should be used to display the page. This metatag does not affect other browsers such as Firefox and Opera, which in general attempt to avoid bloating the size of the browser code by displaying web pages only one way according to established standards. (Supporting multiple rendering engines presents some major challenges, especially when content rendered by one engine accesses embedded content rendered by a different engine).

Examples

<meta http-equiv="Cache-Control" content="no-cache"/> <meta http-equiv="Cache-Control" content="max-age=120"/> <meta http-equiv="Content-Disposition" content="inline; filename=spreadsheet.xls"/> <meta http-equiv="Content-Type" content="application/xhtml+xml;charset=UTF-8"/> <meta http-equiv="Expires" content="Day, dd Mon yyyy hh:mm:ss GMT"/> <meta http-equiv="X-UA-Compatible" content="IE=8"/> <meta http-equiv="X-UA-Compatible" content="IE=edge"/>

  • http-equiv="Content-Language" has been deprecated. The lang attribute should be used instead.
