This page lists the allowed extension values for the name="" attribute of the <meta> element in HTML5. You may add your own values to this list, which makes them legal HTML5 metadata names. We ask that you try to avoid redundancy; if someone has already defined a name that does roughly what you want, please reuse it.
This page lists extension values for the name="" attribute of the HTML <meta> element. You may add your own values to this list.


{|   
For assistance in preparing a specification, see the [[:Category:Specification editing|specification editing]] category and the [https://github.com/tabatkins/bikeshed/ Bikeshed] documentation.
 
If the specification is ready, we ask that you:
 
* '''Avoid redundancy.''' If someone has already defined a name that does roughly what you want, please reuse it.
* '''Be sure to include ''all'' the items''' [http://www.whatwg.org/specs/web-apps/current-work/multipage/semantics.html#other-metadata-names outlined in the spec] ''including a link to a specification'' that specifies the keyword ''as an HTML meta keyword''.  If a proposal lacks a specification and a version in a complete specification exists, the latter is to be preferred.
* '''Alphabetize by keyword''', without regard for case, in any table. Sort nonalphanumerics by ASCII value.
* '''Not reserve namespaces.''' Instead, register individual names (known as enumerated values although you don't have to number them).
 
URL-valued attributes must not be added to this page as meta names but should be registered as [http://microformats.org/wiki/existing-rel-values#HTML5_link_type_extensions rel keywords] instead.

| robots
| A comma-separated list of operators explaining how search engine crawlers should treat the content. This meta name is already supported by every popular search engine.<br />Possible values are "noarchive" to prevent cached versions, "noindex" to prevent indexing, and "nofollow" works as the link rel value with the same name.<br />The content value "NOODP" has been offered elsewhere, so I'm proposing it here. It blocks robots from using [http://www.dmoz.org Open Directory Project] descriptions of a website instead of Web pages' own meta descriptions. It may have been introduced by Microsoft.<br />The content value "NOYDIR" has been offered by Yahoo, so I'm proposing it here. It blocks Yahoo's robot from using the Yahoo directory's descriptions of a website instead of Web pages' own meta descriptions. Whether any other robot supports this is unknown but possibly no other search engine uses Yahoo's directory anyway.

<meta name="WT.sv" content="My Server">
Defines the name of the machine that serves the web page. If you have two servers (Server1 and Server2), you would make two copies of the META tag and designate CONTENT=“Server1” for deployment to pages on the first server and CONTENT=“Server2” for deployment to the same pages on the second server.
For a server farm, you can extract the value of the built-in server name and dynamically assign it to the
META tag using server-side scripting.
Example:
<meta name="WT.sv" content="Server1">
<meta name="WT.sv" content="Server2">

| '''Tracking Page Titles'''
You may want to modify a page title before sending it to Webtrends in the following cases:
* You are dealing with dynamic content pages identified by URL parameters, and the page title represents the title of the base URL page rather than the dynamic content page.
Unless you modify the page titles, all pages have the same title in the reports.
* All pages have been assigned the same title, for reasons of style or company policy.
Even though URLs are displayed in addition to page title, the entire URL cannot be depended upon to distinguish one page from another.
Use server-side scripts to change the title to something that reflects the content of the pages so that you can identify them in reports. Next, pass the customized page titles to Webtrends, using the following META tag:
<META NAME="WT.ti" CONTENT="title">
Defines the name of the title for this page.

| expires
| <code>meta name='expires'</code> defines the expiration date of the page. This can be used for web pages in preparation for an upcoming event, e.g. a registration form for an exposition or competition, or other cases with a pre-set date when the document will no longer be valid, e.g. a product offer in a special sale or a support page for a product known not to be supported anymore from a given time onward.
 
Search engines should respond to this meta tag in a reasonable way, i.e. by removing the page from their main search results after the expiration date (possibly still returning the result in a special search for expired pages as long as the page exists and is not explicitly excluded via <code>robots.txt</code> or <code>meta name='robots'</code> etc.) or simply by indicating to the user that this result is out-of-date.
 
The content attribute should define the expiration date in accordance with http://www.w3.org/TR/NOTE-datetime . The meta tag should not be used for pages without expiration date. However, for historical reasons, search engines should also interpret other date formats where possible and should be prepared to find values such as "", "0", "no" and "never". Such non-date values are to be interpreted as no expiration date.
 
Correctly formatted example:
<code><pre><meta name='expires' content='2012-12-31T23:59Z'></pre></code>
 
This tag is not to be confused with and has a different meaning than <code>meta http-equiv='expires'.</code>

|-valign="top"
| resolutions
| Authoring web sites to use resolution independent images that display beautifully on high-resolution displays should be made as easy as possible for developers and should not require JavaScript to accomplish.
 
To accomplish this, I propose a new HTML Meta Tag, <code>resolutions</code>, that can be used to specify that high-resolution versions of images linked to from the page are available and that the browser should use them in place of the lower-resolution default images if it detects that a user is using a high-resolution screen. The resolutions meta tag lists the device-pixel ratios supported by images in the page.
 
So, for example…
 
<code><pre><meta name="resolutions" content="2x"></pre></code>
 
… means that the developer is telling the browser that she has created 2x resolution images for the images linked to from the current page and named them with a @2x suffix.
 
To illustrate, if her image tag is as follows…
 
<code><pre><img src="/images/flower.jpg" alt="A flower"></pre></code>
 
… then she has two image files under /images: the low-resolution default (flower.jpg), and a higher-resolution (200%) version named [email protected].
 
(This is the same naming convention already used by Apple in its Cocoa Touch framework for automatically loading in higher-resolution versions of images.)
 
Based on the meta tag, if the browser detects that the user is running at a <code>min-device-pixel-ratio</code> of 2.0, it will automatically ask for the 2x version of the image ([email protected]) instead of the default image as specified in the image tag.
 
Finally, so as not to flood external sites with high-resolution image requests, this functionality would only work for local images specified via relative links.
 
<b>Multiple resolutions</b>
 
The resolutions tag can also contain a list of supported device-pixel ratios so as to support even higher-resolution displays when and if they become available in the future.
 
For example:
 
<code><pre><meta name="resolutions" content="2x, 4x, 8x"></pre></code>
 
In this case, the developer would provide 2x, 4x, and 8x versions of all images. So, in the running example, she would make flower.jpg, [email protected], [email protected], and [email protected].
 
<b>Advantages</b>
 
The advantages of this approach are several:
 
<ol>
    <li>Makes it very simple for developers to support high-resolution displays like the iPhone 4's Retina screen</li>
    <li>Does not require JavaScript</li>
    <li>Does not change the default way that things work (if the meta tag is not specified, the browser simply behaves as it always has).</li>
</ol>

Latest revision as of 15:13, 12 October 2023

This page lists extension values for the name="" attribute of the HTML <meta> element. You may add your own values to this list.

For assistance in preparing a specification, see the specification editing category and the Bikeshed documentation.

If the specification is ready, we ask that you:

  • Avoid redundancy. If someone has already defined a name that does roughly what you want, please reuse it.
  • Be sure to include all the items outlined in the spec including a link to a specification that specifies the keyword as an HTML meta keyword. If a proposal lacks a specification and a version in a complete specification exists, the latter is to be preferred.
  • Alphabetize by keyword, without regard for case, in any table. Sort nonalphanumerics by ASCII value.
  • Not reserve namespaces. Instead, register individual names (known as enumerated values although you don't have to number them).

URL-valued attributes must not be added to this page as meta names but should be registered as rel keywords instead.

robots A comma-separated list of operators explaining how search engine crawlers should treat the content. This meta name is already supported by every popular search engine.
Possible values are "noarchive" to prevent cached versions, "noindex" to prevent indexing, and "nofollow" works as the link rel value with the same name.
The content value "NOODP" has been offered elsewhere, so I'm proposing it here. It blocks robots from using Open Directory Project descriptions of a website instead of Web pages' own meta descriptions. It may have been introduced by Microsoft.
The content value "NOYDIR" has been offered by Yahoo, so I'm proposing it here. It blocks Yahoo's robot from using the Yahoo directory's descriptions of a website instead of Web pages' own meta descriptions.

<a href="file222.html?WT.ac=CONTENT222">

The name of the advertisement clicked to reach a particular web page. To capture this information with DCS, the Advertising Click must contain an external redirect back to the client. The redirect needs to

include the necessary code to generate a hit to the DCS. The maximum length for each name is 64 bytes.

Webtrends Parameters Proposal
wt.ad Advertising View parameter

Visitors often view advertisements that they do not necessarily click on. You can use On-Site Advertising to determine the number of visitors to your web site who view particular ads. With this feature you can produce advertising reports for each of your clients. If you are selling advertising space on your web site, for example, you can collect traffic statistics to help determine pricing schedules. The following META tag tracks advertising views: 

<meta name="WT.ad" content="My content">

An Ad View occurs when a visitor views a page containing an ad. An ad is a link or graphic that contains an Ad Click parameter in the query portion of it's URL.

Webtrends Parameters Proposal
wt.cg_n Name of the Content Group

Used to configure the appropriate Webtrends advanced feature. These are just some of the more popular ones. These appear in your META tags. – showing you the web page, the source (meta tag), the log files entry and the subsequent WT report. Example: 

<meta name="wt.cg_n" content="My content">
Webtrends Parameters Proposal
wt.cg_s Name of Content Sub-Group

Used to configure the appropriate Webtrends advanced feature. These are just some of the more popular ones. These appear in your META tags. – showing you the web page, the source (meta tag), the log files entry and the subsequent WT report. Example: 

<meta name="wt.cg_s" content="My content">
Webtrends Parameters Proposal
wt.mc_id Identifies the ID of the marketing campaign

To attract new students, a university launches a marketing campaign by sending recruitment email to all graduating high school seniors in a metropolitan area. The email links to a special landing page in the university’s web site, containing the following META tag to track marketing campaigns. Example: 

<META NAME="WT.mc_id" CONTENT="1X2GG34">

You may use this parameter on the URL. Example: 

<a href="link?WT.mc_id=1X2GG34">

The Campaign ID 1X2GG34 represents recruits to be contacted by email

Webtrends Parameters Proposal
WT.si_n Scenario analysis parameter - scenario name

This defines a scenario name for the page or set of pages to be included in the scenario. This in turn produces a funnel type report in Webtrends. Example: 

<meta name="WT.si_n" content="my_scenario_name">
Webtrends Parameters. Proposal
WT.si_p Scenario analysis parameter - scenario step name

This defines a scenario step name for the page or set of pages to be included in the scenario. This in turn produces a funnel type report in Webtrends. It works when paired with metedata tag name WT.si_n. Example: 

<meta name="WT.si_p" content="my_scenario_step_name">
Webtrends Parameters. Proposal
WT.si_x Scenario analysis parameter - scenario step number

This defines a scenario step number for the page or set of pages to be included in the scenario. This in turn produces a funnel type report in Webtrends. It works when paired with metedata tag name WT.si_n, and as an alternative to Wt.si_p. Example: 

<meta name="WT.si_x" content="my_scenario_step_number">
Webtrends Parameters. Proposal
wt.sv Tracking Servers parameter

If your site is hosted on multiple servers, a server cluster, or a server farm, and you want to evaluate the performance of your load balancer, Webtrends can track page views for each server. To do so, populate the following META tag on all pages on each server: Example: 

<meta name="WT.sv" content="My Server">

Defines the name of the machine that serves the web page. If you have two servers (Server1 and Server2), you would make two copies of the META tag and designate CONTENT=“Server1” for deployment to pages on the first server and CONTENT=“Server2” for deployment to the same pages on the second server. For a server farm, you can extract the value of the built-in server name and dynamically assign it to the META tag using server-side scripting. Example: 

<meta name="WT.sv" content="Server1">
<meta name="WT.sv" content="Server2">

An Ad View occurs when a visitor views a page containing an ad. An ad is a link or graphic that contains an Ad Click parameter in the query portion of it's URL.

About WT.ad. Proposal
wt.ti Tracking Page Titles

You may want to modify a page title before sending it to Webtrends in the following cases:

  • You are dealing with dynamic content pages identified by URL parameters, and the page title represents the title of the base URL page rather than the dynamic content page.

Unless you modify the page titles, all pages have the same title in the reports.

  • All pages have been assigned the same title, for reasons of style or company policy.

Even though URLs are displayed in addition to page title, the entire URL cannot be depended upon to distinguish one page from another. Use server-side scripts to change the title to something that reflects the content of the pages so that you can identify them in reports. Next, pass the customized page titles to Webtrends, using the following META tag: 

<META NAME="WT.ti" CONTENT="title">

Defines the name of the title for this page.

expires meta name='expires' defines the expiration date of the page. This can be used for web pages in preparation for an upcoming event, e.g. a registration form for an exposition or competition, or other cases with a pre-set date when the document will no longer be valid, e.g. a product offer in a special sale or a support page for a product known not to be supported anymore from a given time onward.

Search engines should respond to this meta tag in a reasonable way, i.e. by removing the page from their main search results after the expiration date (possibly still returning the result in a special search for expired pages as long as the page exists and is not explicitly excluded via robots.txt or meta name='robots' etc.) or simply by indicating to the user that this result is out-of-date.

The content attribute should define the expiration date in accordance with http://www.w3.org/TR/NOTE-datetime . The meta tag should not be used for pages without expiration date. However, for historical reasons, search engines should also interpret other date formats where possible and should be prepared to find values such as "", "0", "no" and "never". Such non-date values are to be interpreted as no expiration date.

Correctly formatted example: 

<meta name='expires' content='2012-12-31T23:59Z'>

This tag is not to be confused with and has a different meaning than meta http-equiv='expires'.

resolutions Authoring web sites to use resolution independent images that display beautifully on high-resolution displays should be made as easy as possible for developers and should not require JavaScript to accomplish.

To accomplish this, I propose a new HTML Meta Tag, resolutions, that can be used to specify that high-resolution versions of images linked to from the page are available and that the browser should use them in place of the lower-resolution default images if it detects that a user is using a high-resolution screen. The resolutions meta tag lists the device-pixel ratios supported by images in the page.

So, for example… 

<meta name="resolutions" content="2x">

… means that the developer is telling the browser that she has created 2x resolution images for the images linked to from the current page and named them with a @2x suffix.

To illustrate, if her image tag is as follows… 

<img src="/images/flower.jpg" alt="A flower">

… then she has two image files under /images: the low-resolution default (flower.jpg), and a higher-resolution (200%) version named [email protected].

(This is the same naming convention already used by Apple in its Cocoa Touch framework for automatically loading in higher-resolution versions of images.)

Based on the meta tag, if the browser detects that the user is running at a min-device-pixel-ratio of 2.0, it will automatically ask for the 2x version of the image ([email protected]) instead of the default image as specified in the image tag.

Finally, so as not to flood external sites with high-resolution image requests, this functionality would only work for local images specified via relative links.

Multiple resolutions

The resolutions tag can also contain a list of supported device-pixel ratios so as to support even higher-resolution displays when and if they become available in the future.

For example: 

<meta name="resolutions" content="2x, 4x, 8x">

In this case, the developer would provide 2x, 4x, and 8x versions of all images. So, in the running example, she would make flower.jpg, [email protected], [email protected], and [email protected].

Advantages

The advantages of this approach are several:

  1. Makes it very simple for developers to support high-resolution displays like the iPhone 4's Retina screen
  2. Does not require JavaScript
  3. Does not change the default way that things work (if the meta tag is not specified, the browser simply behaves as it always has).
