Magento – Magento 2: Meta-keywords and meta-description doesn’t appear

What i understood that Google database still not updated.

You can do following

1)Generate sitemap.xml and place in your site root.

2)Put robot.txt in your site root.

3)Make your keyword formatted. Now there are many empty spaces before after.

It should be like follwing

<meta name="description" content="Up to date ladies fashion at affordable prices." />
<meta name="keywords" content="Fashion,boutique,ladies,dress,shirt,necklace" />

The Meta Description for each page is loaded in the file

[your magento install dir]/app/design/frontend/YOURPACKAGE/YOURTHEME/template/page/html/head.phtml

If your theme does not have its own head.phtml file then look in the /default/default/ and /base/default/ directories

By default the code which renders the Meta Description looks like this

<meta name="description" content="<?php echo htmlspecialchars($this->getDescription()) ?>" />

So first check for possible changes in this code.

Now for product pages the getDescription() function call gets its data from

[your magento install dir]/app/code/core/Mage/Catalog/Block/Product/View.php

By default the _prepareLayout() function in this file should contain the following code for retreiving the Meta Description

        $description = $product->getMetaDescription();
        if ($description) {
            $headBlock->setDescription( ($description) );
        } else {
            $headBlock->setDescription(Mage::helper('core/string')->substr($product->getDescription(), 0, 255));
        }

So also check this code for any changes. This code could also be overwritten in

[your magento install dir]/app/code/local/Mage/Catalog/Block/Product/View.php

If you do not find any changes then this may be caused by some extenion. A good way to trouble shoot is to disable all extensions (one by one) and/or change to the base/default theme to see what happens.
