Broadcast

Network Content Syndication Made Easy!

Single source content on a WordPress multisite network is now as easy as pie! Syndicate posts to other blogs in the network, update posts between blogs, sync posts, share content templates, etc. Broadcasted posts can be linked to their parents, which updates child posts when the parent post is updated. This includes all data: title, slug, content, custom fields, attachments, etc.

Broadcast is great for:

• Chain stores
• Content hubs
• Franchises
• News sites
• Schools
• Anything else with distributed content!

Here are some use cases for Broadcast:

• Broadcast in the school classroom
• Franchising with WordPress and Broadcast
• On-Demand Content Syndication with Broadcast Parent Pull
• Sharing forms on a WordPress network
• Wholesale with WooCommerce and Broadcast
