This can be workaround by installing plug All in One SEO. But for those who concern plugin will slow down their sites, here is a simple hack, all needs to do here is just adding a few lines in header.php.

Firstly open header.php, find this line <meta http-equiv=”content-type” content=”text/html; charset=<?php bloginfo(‘charset’); ?>” />

Secondly, add following code after it.

<?php if (is_single()){
$description =  substr(strip_tags($post->post_content),0,220);
$keywords = “”;
$tags = wp_get_post_tags($post->ID);
foreach ($tags as $tag ) {
$keywords = $keywords . $tag->name . “, “;
}
}else{
$description = “REPLACE W HOMEPAGE DESCRIPTION STRINGS“;
$keywords = “REPLACE W HOMEPAGE KEYWORDS“;
}
?>
<meta name=”keywords” content=”<?php echo $keywords; ?>” />
<meta name=”description” content=”<?php echo $description; ?>” />

Here is how it works, when a web page is loaded, wordpress will check page type, if it’s a single post, tags strings will be set as keywords and the first 220 letters of post will be set as descriptions. Otherwise, a hard coded keyword and description strings will be set.

Now giving up adding keywords and description in every single post and get rid of All in One SEO.
