SEO for WordPress site [Part 1] - SEO for Posts-Articles -

In order to do SEO of WordPress sites, many people use SEO plugins.

But, if you are a small web-site (such as our demonstration site) owner, you maybe think plugins are too heavy for your site.

So, today, we will guide you how to put the basic meta-tags "robots", "description", "keywords", "canonical" to the Posts-Articles without plugin. Our DEMO site runs on the way.

How to put meta-tags in a Post-Article

"Keywords": made by "tag"
"Description": made by the valuethat you wrote in the "Excerpt" column
"Canonical": made by the value that you wrote in the "Custom Fields" column
"Robots": made by the value that you wrote in the "Custom Fields" column

How to create meta tags for a Post-Article

(1) Create a PHP file. In this article, for the sake of convenience, the file name is "header-SEO.php".
(2) Put header-SEO.php into header.php. Put it above of header.php. In order to do so, copy and paste the contents in the frame below.

<?php get_template_part('header-SEO'); ?>

(3) Click "Posts" on your WordPress Admin-Window, and open the article you'd like to do SEO. If the "tag" column is empty, write (a) tag(s).
(4) Write the character corresponding to the "description" on the "Excerpt" column of the "Posts-Window". 150-160 characters would be good. Count the number of characters by using the "Counting Letters of the Rainbow-Link".
(5) To the "Custom Fields" column of the "Post-Window", create a name called "meta_canonical". And copy and paste a permanent link to the "value" field. It is corresponding to the "canonical" of the meta-tag.
(6) To the "Custom Fields" column of the "Post-Window", create a name called "meta_robots". And write "index" to the "value" field. It is corresponding to the "robots" of the meta-tag.
(7) Open the "header-SEO.php", and copy and paste the contents of the frame below.

<?php
/////////////////////SEO for Posts-Articles | If you use any SEO plugin, delete below. ////////////////////////
/* Created by RainbowLink Inc. */
if(is_single()){
global $post;  if ( have_posts() ) : while ( have_posts() ) : the_post();
$posttags = get_the_tags(); $meta_dec = get_the_excerpt(); $meta_dec2 = mb_strimwidth($meta_dec, 0, 200, "…", "UTF-8"); $meta_dec2 = str_replace('"',"'",$meta_dec2); $meta_canonical = post_custom('meta_canonical'); $meta_robots = post_custom('meta_robots'); if($posttags) { ?>
<meta name="keywords" content="<?php   foreach ( $posttags as $tag ) {    echo $tag->name . ',';   } ?>">
<?php } if(!empty($meta_dec2)) { ?>
<meta name="description" content="<?php echo $meta_dec2; ?>">
<?php } if(!empty($meta_canonical)) { ?>
<meta name="canonical" content="<?php echo $meta_canonical; ?>">
<?php } if(!empty($meta_robots)) { ?>
<meta name="robots" content="<?php echo $meta_robots; ?>">
<?php } endwhile;		endif;   }
?>

Updated

Aug 4, 2024　We have changed the description regarding www.secure-formmail.net. (detail: We are running a demo site for WordPress plugins we developed on our domain called www.secure-formmail.net. For www.secure-formmail.net, we used an overseas hosting service from August 1, 2016 to July 31, 2024 in order to prove that our plugins "work normally" on a "general shared hosting service". However, as the number of users is decreasing significantly, we decided to operate www.secure-formmail.net within our own data center starting August 1, 2024. )

May 13, 2022　Upgrade for PHP8

Jan 16, 2022　Added: $meta_dec2 = str_replace('"',"'",$meta_dec2);

May 3, 2018 Deleted a paragraph of "If your WordPress displays robot tag in header.php doubly, please do (A)(B) below."

Jan 15, 2017 Added a paragraph of "If your WordPress displays robot tag in header.php doubly, please do (A)(B) below."

May 24, 2017 on Jan 15, 2017, when we added a paragraph of "If your WordPress displays robot tag in header.php doubly, please do (A)(B) below.", by mistake, we added ( opened ) another paragraph "If your WordPress displays empaty title tag in header.php, please do (A)(B) below.". The paragraph was for another SEO article, "SEO for WordPress site [Part 3] - SEO for Titles -". So, on May 24, 2017, when we released the article, "SEO for WordPress site [Part 3] - SEO for Titles -", we deleted the wrong paragraph "If your WordPress displays empaty title tag in header.php, please do (A)(B) below." from this article.
