A sitemap will help your website in general because search engines will regard it as an invitation to crawl and index the pages mentioned. There are two types of sitemaps: HTML and XML, each with its own set of benefits and uses for SEO.
Copy and paste the code below into your theme’s function.php file
add_action("publish_post", "eg_create_sitemap");
add_action("publish_page", "eg_create_sitemap");
function eg_create_sitemap() {
$postsForSitemap = get_posts(array(
'numberposts' => -1,
'orderby' => 'modified',
'post_type' => array('post','page'),
'order' => 'DESC'
));
$sitemap = '<?xml version="1.0" encoding="UTF-8"?>';
$sitemap .= '<?xml-stylesheet type="text/xsl" href="sitemap-style.xsl"?>';
$sitemap .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';
foreach($postsForSitemap as $post) {
setup_postdata($post);
$postdate = explode(" ", $post->post_modified);
$sitemap .= '<url>'.
'<loc>'. get_permalink($post->ID) .'</loc>'.
'<priority>1</priority>'.
'<lastmod>'. $postdate[0] .'</lastmod>'.
'<changefreq>daily</changefreq>'.
'</url>';
}
$sitemap .= '</urlset>';
$fp = fopen(ABSPATH . "sitemap.xml", 'w');
fwrite($fp, $sitemap);
fclose($fp);
}Now create a file named sitemap-style.XSL and paste the code below into that file, then save it with the same name
<?xml version="1.0" encoding="UTF-8"?><xsl:stylesheet version="2.0" xmlns:html="http://www.w3.org/TR/REC-html40"xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:sitemap="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:template match="/"><xsl:variable name="fileType"> <xsl:choose> <xsl:when test="//sitemap:url">Sitemap</xsl:when> <xsl:otherwise>SitemapIndex</xsl:otherwise> </xsl:choose> </xsl:variable><html xmlns="http://www.w3.org/1999/xhtml"><head><title><xsl:choose><xsl:when test="$fileType='Sitemap'">Sitemap</xsl:when><xsl:otherwise>Sitemap Index</xsl:otherwise></xsl:choose></title><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><style type="text/css">body {font-family:Helvetica,Arial,sans-serif;font-size:68.5%;}table {border:none;border-collapse:collapse;}table {font-size:1em;width:100%;}th {text-align:left;padding:5px;}tr.stripe {background-color:#f7f7f7;}</style></head> <body> <div id="content"> <h1>XML Sitemap By EXEIdeas</h1> <div> <p><xsl:choose><xsl:when test="$fileType='Sitemap'"> This sitemap contains <xsl:value-of select="count(sitemap:urlset/sitemap:url)"></xsl:value-of> URLs</xsl:when> <xsl:otherwise>This sitemap index contains <xsl:value-of select="count(sitemap:sitemapindex/sitemap:sitemap)"></xsl:value-of> sitemaps</xsl:otherwise></xsl:choose></p> </div><xsl:choose><xsl:when test="$fileType='Sitemap'"><xsl:call-template name="sitemapTable"/></xsl:when> <xsl:otherwise><xsl:call-template name="siteindexTable"/></xsl:otherwise></xsl:choose> </div> </body> </html> </xsl:template> <xsl:template name="siteindexTable"> <table cellpadding="3"><thead><tr><th width="50%">URL</th><th>LastChange</th></tr></thead><tbody><xsl:variable name="lower" select="'abcdefghijklmnopqrstuvwxyz'"/><xsl:variable name="upper" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/><xsl:for-each select="sitemap:sitemapindex/sitemap:sitemap"><tr><xsl:if test="position() mod 2 != 1"><xsl:attribute name="class">stripe</xsl:attribute></xsl:if><td><xsl:variable name="itemURL"><xsl:value-of select="sitemap:loc"/></xsl:variable><a href="{$itemURL}"><xsl:value-of select="sitemap:loc"/></a></td><td><xsl:value-of select="concat(substring(sitemap:lastmod,0,11),concat(' ', substring(sitemap:lastmod,12,5)))"/></td></tr></xsl:for-each></tbody></table> </xsl:template> <xsl:template name="sitemapTable"><table cellpadding="3"><thead><tr><th width="50%">URL</th><th>Priority</th><th>Change Frequency</th><th>LastChange</th></tr></thead><tbody><xsl:variable name="lower" select="'abcdefghijklmnopqrstuvwxyz'"/><xsl:variable name="upper" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/><xsl:for-each select="sitemap:urlset/sitemap:url"><tr><xsl:if test="position() mod 2 != 1"><xsl:attribute name="class">stripe</xsl:attribute></xsl:if><td><xsl:variable name="itemURL"><xsl:value-of select="sitemap:loc"/></xsl:variable><a href="{$itemURL}"><xsl:value-of select="sitemap:loc"/></a></td><td><xsl:if test="string(number(sitemap:priority))!='NaN'"><xsl:value-of select="concat(sitemap:priority*100,'%')"/></xsl:if></td><td><xsl:value-of select="concat(translate(substring(sitemap:changefreq, 1, 1),concat($lower, $upper),concat($upper, $lower)),substring(sitemap:changefreq, 2))"/></td><td><xsl:value-of select="concat(substring(sitemap:lastmod,0,11),concat(' ', substring(sitemap:lastmod,12,5)))"/></td></tr></xsl:for-each></tbody></table> </xsl:template></xsl:stylesheet>
