I am trying to automatically add the current year to the meta title and description in for example category-pages. I want to achieve something like this:

Meta title: "The best category items for year" >> "The best category items for 2019"

What would be the easiest way to do this?

In this case, you can use event/observer.

Fire an observer on the event catalog_category_load_after at frontend area set meta description on the fly.

Create events.xml at
app/code/StackExchange/Magento/etc/frontend/ and as
`events.xml location under on frontend and this event only fire
for frontend area.

events.xml code

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
 <event name="catalog_category_load_after">
 <observer instance="StackExchangeMagentoObserverFrontendCatalogCategoryLoadAfter" 
 name="stackexchange_magento_observer_frontend_catalog_categoryloadafter_catalog_product_load_after"
 />
 </event>
</config>

Create Observer class CategoryLoadAfter at
app/code/StackExchange/Magento/Observer/Frontend/Catalog/.

CategoryLoadAfter.php code

<?php
namespace StackExchangeMagentoObserverFrontendCatalog;

class CategoryLoadAfter implements MagentoFrameworkEventObserverInterface 

 /**
 * @var PsrLogLoggerInterface
 */
 private $logger;

 public function __construct(
 PsrLogLoggerInterface $logger
 ) 

 $this->logger = $logger;
 
 /**
 * Execute observer
 *
 * @param MagentoFrameworkEventObserver $observer
 * @return void
 */
 public function execute(
 MagentoFrameworkEventObserver $observer
 ) 
 $this->logger->debug(__METHOD__);
 $category = $observer->getEvent()->getCategory();
 if ($category instanceof MagentoCatalogModelCategory) 
 $oldMetaTitle = $category->getMetaTitle();
 $oldMetaDescription = $category->getMetaDescription();
 $oldMetaKeyword = $category->getMetaKeywords();
 $category->setMetaTitle(str_replace("year",date('Y'),$oldMetaTitle));
 $category->setMetaDescription(str_replace("year",date('Y'),$oldMetaDescription));
 $category->setMetaKeywords(str_replace("year",date('Y'),$oldMetaKeyword));
 
 

Also, your module must have:

1. app/code/Vendor/Modulename/etc/module.xml


2. app/code/Vendor/Modulename/composer.json


3. app/code/Vendor/Modulename/registration.php

After adding the event you should flush the cache.
