<p>一个网页的关键词的密度是怎样来衡量的，是不是就是关键词出现的频度除以总的词数？？</p><p>那在&lt;title&gt;&lt;meta&gt;中的关键词算不算，请指教</p>

<p class="style7" style="MARGIN: auto 0cm; TEXT-INDENT: 21pt; LINE-HEIGHT: 150%;"><b style="mso-bidi-font-weight: normal;"><span style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;"></span></b></p><p class="style7" style="MARGIN: auto 0cm; TEXT-INDENT: 21pt; LINE-HEIGHT: 150%;"><b style="mso-bidi-font-weight: normal;"><span style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">关键字密度</span></b><span style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">就是你所强调的关键字或关键词在网页中出现的次数与网页中其它文本内容的比例。</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; FONT-FAMILY: Tahoma;"><p></p></span></p><p class="style7" style="MARGIN: auto 0cm; LINE-HEIGHT: 150%;"><span style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; mso-ascii-font-family: Tahoma; mso-hansi-font-family: Tahoma; mso-bidi-font-family: Tahoma;">举例说明：</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; FONT-FAMILY: Tahoma;"><p></p></span></p><p style="LINE-HEIGHT: 150%;"><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">&lt;html&gt;<br/>&lt;head&gt;<br/>&lt;title&gt;keyword1,keyword2,keyword3&lt;/title&gt;<br/>&lt;meta name="keyword" contend="keyword1,keyword2,keyword3"&gt;<br/>&lt;meta name="description" contend="keyword1 and keyword2"&gt;<br/>&lt;/head&gt;<br/>&lt;body&gt;<br/>keyword1 and keyword2, keyword3 and so on</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">！</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;"><br/>&lt;/body&gt;<br/>&lt;/htmL&gt;<p></p></span></p><p style="LINE-HEIGHT: 150%;"><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">在这个页面中，除去</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">html</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">代码，文本内容为：</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;"><p></p></span></p><p class="style7" style="MARGIN: auto 0cm; LINE-HEIGHT: 150%;"><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">"keyword1,keyword2, keyword3" <br/>"keyword1,keyword2,keyword3" <br/>"keyword1 and keyword2"<br/>"keyword1 and keyword2, keyword3 and so on</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">！</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">"</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%; FONT-FAMILY: Tahoma;"><p></p></span></p><p class="style7" style="MARGIN: auto 0cm; LINE-HEIGHT: 150%;"><span style="FONT-SIZE: 10.5pt; COLOR: black; LINE-HEIGHT: 150%;">一共是<span lang="EN-US">16</span>个单词，</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">keyword1</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">出现的次数是</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">4</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">次，那么</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">keyword1</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">在该网页中的关键词密度为：</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">4/16</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">＝</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;">25</span><span style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; mso-ascii-font-family: Arial; mso-hansi-font-family: Arial; mso-bidi-font-family: Arial;">％。</span><span lang="EN-US" style="FONT-SIZE: 10.5pt; LINE-HEIGHT: 150%; FONT-FAMILY: Arial;"><p></p></span></p>
