How do I add a meta keyword tag to each page of my Drupal application?

In Drupal, you can add a meta keyword tag to each page by using the Metatag module. Here are the steps to follow:

1. Install the Metatag module: You can install the Metatag module through the Drupal module installer.
2. Configure the Metatag module: Once you have installed the Metatag module, you will need to configure it to include a meta keyword tag. To do this, navigate to "Configuration" -> "Search and Metatags" -> "Metatag" and click on the "Global" tab.
3. Add the Meta Keyword tag: Scroll down to the "Keywords" section and enter the desired keywords for your site in the "Default value" field. You can enter multiple keywords separated by a comma.
4. Save changes: Once you have entered the desired keywords, save the changes by clicking on the "Save configuration" button.
5. Override meta tags on individual pages: If you want to specify different meta keywords for different pages, you can override the global setting by going to the "Edit" tab for each page and specifying the desired keywords in the "Keywords" section.

Note: You should always use relevant keywords that accurately describe the content on each page. Overusing or using irrelevant keywords can result in a penalty from search engines.
