Magento2 - Remove Meta Keywords from all pages

Question

I'm currently developing some Magento2 themes. I noticed that in Magento2 Meta Keywords are still added. I want to remove this meta keywords from all pages, does anyone know the proper way to achieve this?

I did find meta.phtml, but I think this file is not used on a product page. Also the file Product/View.php adds the keywords with this function:

$this->pageConfig->setKeywords($keyword);

but I don't think it would be the prober way to extend the _prepareLayout function, right?

Thanks.

Answer 1

I just had to do the same and decided to just add a plugin after the getKeywords Method of the page config which returns an empty string. works great

di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Framework\View\Page\Config">
        <plugin name="removeMetaKeywords" type="Vendor\Module\Plugin\PageConfig\RemoveMetaKeywords" sortOrder="9999"/>
    </type>
</config>

Plugin Class:

<?php
declare(strict_types = 1);
namespace Vendor\Module\Plugin\PageConfig;

class RemoveMetaKeywords
{
    public function afterGetKeywords($subject, string $return)
    {
        return '';
    }
}

Answer 2

Easy to remove or edit default meta keywords at admin configuration:

Store > Configuration > Design [General] - HTML Head

Answer 3

Just override the Magento\Framework\View\Page\Config\Renderer

As this class's the method renderMetadata responsible for meta keywords render. On the override class's at that method add this condition:

 // add this code for stop render of keywords
    if ($name = 'keywords') {
        continue;
    }

Override function may be look

public function renderMetadata()
    {
        $result = '';
        foreach ($this->pageConfig->getMetadata() as $name => $content) {
            $metadataTemplate = $this->getMetadataTemplate($name);
            if (!$metadataTemplate) {
                continue;
            }
            // add this code for stop render of robot
            if ($name == 'keywords') {
                continue;
            }
            $content = $this->processMetadataContent($name, $content);
            if ($content) {
                $result .= str_replace(['%name', '%content'], [$name, $content], $metadataTemplate);
            }
        }
        return $result;
    }
