WTM LAB

WTMLab-Meta is a universal custom meta tags plugin developed by <a href="https://wtmlab.com" rel="nofollow ugc">WTM Lab</a> that gives you complete control over your website’s metadata. With <a href="https://wtmlab.com/wordpress/wtmlab-meta-plugin/" rel="nofollow ugc">WTMLab-Meta</a> you can easily manage and customize meta tags, meta robots on all pages of your website—including posts, pages, taxonomy term pages (categories, tags, etc.), author pages, and archives.
Key Features: 
* Dynamic Title Management: 
 Override the default title with a custom meta title if provided. If left empty, the plugin automatically falls back to the default post/page (or term/author/archive) title. 
* Automatic Meta Description Fallback: 
 If you don’t supply a meta description, the plugin uses your post excerpt or a trimmed version of your content. 
* Social Sharing Integration: 
 Automatically generate Open Graph and Twitter Card tags using your custom values. If not provided, they default to your meta description and featured image. 
* Canonical URL & Meta Robots ags: 
 Specify a custom canonical URL (or let the plugin default to your post permalink) and set robots directives (noindex, nofollow) to help prevent duplicate content issues. 
* Custom Head Code Insertion: 
 Easily insert any additional code (such as Google Analytics tracking code or meta verification tags) directly into the <code><head></code> section. 
* Universal Support: 
 Custom meta fields are available for posts/pages, taxonomy terms (categories, tags, and other custom taxonomies), author pages (via user meta), and archive pages (via an options page).
All meta tags are output early in the head section (hooked at priority 1) to ensure optimal performance and compatibility with other meta elements like the viewport tag.
