if statement for additional text in tpl_main_page.php

I wanted to use EZpages text to display below the category pictures.
I started with this code:

<!--bof- SEO Ezpage text -->
<div id="seo_content">
	<?php 
    $page_query = $db->Execute("SELECT pages_html_text FROM zen_ezpages WHERE pages_title='SEO'");
    $seo_text = $page_query->fields['pages_html_text'];
    echo $seo_text;
    ?>
</div>
<!--eof- SEO Ezpage text -->

It displays the text where I want it BUT now it shows on all pages. Could I put an if statement to make it ONLY show on the home page? I have tried but my php is not solid at all. Any suggestions?

I think this should work. Any comments on the code appreciated. Just getting my feet wet with php.

<!--bof- SEO Ezpage text -->
<div id="seo_content">
<?php
if ($this_is_home_page) {
    $page_query = $db->Execute("SELECT pages_html_text FROM zen_ezpages WHERE pages_title='SEO'");
    $seo_text = $page_query->fields['pages_html_text'];
    echo $seo_text;
    } ?>  
</div>
<!--eof- SEO Ezpage text -->
