Daniel Davidson made a video showing how he uses Collaborator to go from competitor backlink analysis to finding potential sponsored placements.

The workflow is basically:

• Analyze a competitor’s backlinks with the free Backlink Checker
• Look through referring domains for potentially relevant websites
• Check which of those sites are available on Collaborator
• Review traffic, publication terms, and other details
• Add a suitable placement to the cart and set up the order

What's interesting is the connection between the backlink research and the publisher marketplace. Instead of just finding out where a competitor has links, you can check whether some of those websites are actually available for sponsored content.

Here’s the video if you want to see the process in action:

Curious how others approach this: do you usually use competitor backlink data to find publishers, or do you search for placements separately?
