Setting SEO Tanpa Plugin SEO Wordpress

Timbul pertanyaan, "Setting SEO Tanpa Plugin SEO Wordpress?". Wah beruntung ada temen yang berkenan share.  Kuncinya Edit Function.php masukan Kode Berikut:

function meta_seo() {
 $desc_length = 30;
 $use_excerpt = 1;
 $key = diskripsi;
 global $cat, $cache_categories, $wp_query, $wp_version;
 if((is_single() || is_page())&& !is_attachment()) {
 $post = $wp_query->post;
 $post_custom = get_post_custom($post->ID);
 $custom_desc_value = $post_custom["$key"][0];
 if($custom_desc_value) {
 $text = $custom_desc_value;
 } elseif($use_excerpt && !empty($post->post_excerpt)) {
 $text = $post->post_excerpt;
 } else {
 $text = $post->post_content;
 }
 $text = str_replace(array("
", " ", "
", " "), " ", $text);
 $text = str_replace(array("""), "", $text);
 $text = trim(strip_tags($text));
 $text = explode( , $text);
 if(count($text) > $desc_length) {
 $l = $desc_length;
 $more = ...;
 } else {
 $l = count($text);
 $more = ;
 }
 $description = ;
 for ($i=0; $i<$l; $i++)
 $description .= $text[$i] . ;
 $description .= $more;
 if($description) {
 echo "<meta name="description" content="$description" />
";
 }
 $postTags = get_the_tags();
 if($postTags){
 $tagNames = array();
 foreach($postTags as $tag) {
 $tagNames[] = $tag->name;
 }
 }
 $kiword = implode($tagNames,", ");
 if($kiword) {
 echo "<meta name="keywords" content="$kiword" />
";
 }
 }
 elseif (is_paged() || is_day() || is_tag() || is_search() || is_month() || is_year()) {
 echo "<meta name="robots" content="noindex,follow" />
";
 }
}
Lalu EDIT Header.php, masukan kode berikut:
<?php meta_seo(); ?>
</head>
