Calling Tags From my blog post to header keywords for SEO purpose. Is this Safe Code?
 

<meta name="keywords" content="<?php
$title_slug = substr($_SERVER['REQUEST_URI'], strpos( $_SERVER['REQUEST_URI'],'/video') + 7);
$title_slug = rtrim( $title_slug,"/" );
$sqls = "SELECT * FROM posts where title_slug='" . sanitizeInput($title_slug) . "' ORDER BY id DESC";
$result = mysqli_query($conn, $sqls);
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
$actortags = $row['actor_tags'];
echo $actortags;
}
}

thaanks!

Do not bother using meta keywords. They're ignored by Google + other search engines and the only benefit they serve would be to give competing websites a look at the search terms you're targeting.

Yeah ^ These days Google will look at the meta KWs, giggle, then ignore it. ...But SEs like Bing, Baidu, Yahoo, Yandex, probably Duck Duck Go, etc. still use it, so why not try it? :upsidedow
