Search engine friendly html meta tag needed : <p>My Six month old Website is not listed in google page rank well. Is there any modification required?</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;

&lt;head&gt;
&lt;title&gt;&lt;?php echo $page_title; ?&gt;&lt;/title&gt;
&lt;meta http-equiv="description" content="&lt;?php echo $page_description; ?&gt;" /&gt;

&lt;meta name="robots" content="index, follow" &gt;
&lt;meta name="keywords" content=" site key words" &gt;
&lt;meta name="classification" content="site classification" &gt;
&lt;meta name="rating" content="general" &gt;
&lt;meta name="distribution" content="global" &gt;
&lt;meta name="author" content="site author" &gt;

&lt;/head&gt;
</code></pre>
