The NextGEN Facebook plugin was forked in 2014 and replaced by the WPSSO Core plugin — they’re both Free and available on WordPress.org, have the same author and developer, the same solid core features and code-base, but WPSSO Core is distributed without the social sharing buttons and their related features. Social sharing buttons are distributed separately, as optional extensions for WPSSO Core. WPSSO Core also provides several other useful and optional extensions:
- WPSSO FAQ Manager to manage FAQ categories with Question and Answer pages.
- WPSSO Inherit Parent Metadata to inherit featured and custom images.
- WPSSO Mobile App Meta Tags to manage mobile App information.
- WPSSO Organization Markup to manage multiple Organizations.
- WPSSO Place and Local SEO Markup to manage multiple locations.
- WPSSO Product Metadata for WooCommerce to add GTIN, GTIN-8, GTIN-12 (UPC), GTIN-13 (EAN), GTIN-14, ISBN, MPN, depth, and volume for WooCommerce products and variations.
- WPSSO Ratings and Reviews to add ratings in WordPress comments.
- WPSSO REST API to add meta tags and Schema markup in REST API queries.
- WPSSO Ridiculously Responsive Social Sharing Buttons to add responsive share buttons.
- WPSSO Schema Breadcrumbs Markup to add Breadcrumbs markup for Google.
- WPSSO Schema JSON-LD Markup to provide Google with Schema markup in its preferred format.
- WPSSO Shipping Delivery Time for WooCommerce to provide Google with shipping rates and delivery time estimates.
- WPSSO Strip Schema Microdata to strip incorrect markup from templates.
- WPSSO Tune WP Image Editors for better looking WordPress thumbnails.
- WPSSO User Locale Selector to switch languages quickly and easily.
Until recently, NextGEN Facebook existed independently and in parallel to WPSSO Core, but in the last version of NextGEN Facebook (8.46.1), a notice has been added to the plugin’s description and in the WordPress admin interface (shown on the WordPress Dashboard and plugin settings pages after it has been active for 3 days). The description notice suggests using WPSSO Core instead, while the WordPress admin notice suggests uninstalling NextGEN Facebook and installing WPSSO Core instead (with an optional update button available within the notice). If you’re using the Free version of NextGEN Facebook, you should update to the WPSSO Core plugin as soon as possible.
