+ <p>This page about typefaces on British motorways uses a
+ <code><a href="#meta">meta</a></code> element to specify some keywords that users
+ might use to look for the page:</p>
+
+ <pre><!DOCTYPE HTML>
+<html>
+ <head>
+ <title>Typefaces on UK motorways</title>
+ <meta name="keywords" content="british,type face,font,fonts,highway,highways">
+ </head>
+ <body>
+ ...</pre>
+
+ </div>
+
+ <p class="note">Many search engines do not consider such keywords,
+ because this feature has historically been used unreliably and
+ even misleadingly as a way to spam search engine results in a way
+ that is not helpful for users.</p>
+
+ <div class="impl">
+
+ <p>To obtain the list of keywords that the author has specified as
+ applicable to the page, the user agent must run the following
+ steps:</p>
+
+ <ol><li><p>Let <var title="">keywords</var> be an empty
+ list.</li>
+
+ <li>
+
+ <p>For each <code><a href="#meta">meta</a></code> element with a <code title="attr-meta-name"><a href="#attr-meta-name">name</a></code> attribute and a <code title="attr-meta-content"><a href="#attr-meta-content">content</a></code> attribute and whose
+ <code title="attr-meta-name"><a href="#attr-meta-name">name</a></code> attribute's value is
+ <code title="meta-keywords"><a href="#meta-keywords">keywords</a></code>, run the following
+ substeps:</p>
+
+ <ol><li><p><a href="#split-a-string-on-commas" title="split a string on commas">Split the value
+ of the element's <code title="attr-meta-content">content</code>
+ attribute on commas</a>.</li>
+
+ <li><p>Add the resulting tokens, if any, to <var title="">keywords</var>.</li>
+
+ </ol></li>
+
+ <li><p>Remove any duplicates from <var title="">keywords</var>.</li>
+
+ <li><p>Return <var title="">keywords</var>. This is the list of
+ keywords that the author has specified as applicable to the
+ page.</li>
+
+ </ol><p>User agents should not use this information when there is
+ insufficient confidence in the reliability of the value.</p>
+
+ <p class="example">For instance, it would be reasonable for a
+ content management system to use the keyword information of pages
+ within the system to populate the index of a site-specific search
+ engine, but a large-scale content aggregator that used this
+ information would likely find that certain users would try to game
+ its ranking mechanism through the use of inappropriate
+ keywords.</p>
