I looked at this a while back and it was involved plugins or modifying custom templates etc (and search results still seem to yield the same methods). However- it actually appears to be a lot simpler (not sure whether this is new or my searches just came up a bit short!
So- here’s how!
- Login to your wordpress dashboard
- Click settings
- Click sharing
- Drag the relevant sharing options from “available services” to “enabled services”
- Configure the relevant options
- Click save
