If you wish, you can add social sharing button features to WPSSO using the WPSSO SSB extension plugin (both Free and Pro versions of the WPSSO SSB plugin are available). The combination of WPSSO and WPSSO SSB is functionally equivalent to NGFB.
Several extensions are also available for WPSSO:
- WPSSO Mobile App Meta
- WPSSO Organization Markup
- WPSSO Place / Location and Local Business Meta
- WPSSO Ridiculously Responsive Social Sharing Buttons
- WPSSO Schema JSON-LD Markup
- WPSSO Social Sharing Buttons
