Welcome to the Q&A Forum

I'm trying to be mature and employ the Topic Cluster strategy to my content. In doing so I realized there are a few URL options. Some more difficult to execute than others.

-Is it important to call out the Pillar Topic in your subtopic URL?
-Does the Pillar Topic need to have its own landing page? (As opposed to just being part of the blog.)

Here's an Example:

My Pillar is: Inbound vs. Outbound
My subtopic is: Marketing Platforms

Here are the URL options I can think of...

Option 1: https://pipelineinbound.com/blog/inbound-vs-outbound-marketing-platforms/

Option 2: https://pipelineinbound.com/blog/which-marketing-platforms/

Option 3: https://pipelineinbound.com/blog/marketing-platforms-inbound-vs-outbound/

Option 4 (Hardest): https://pipelineinbound.com/inbound-vs-outbound/marketing-platforms/

Are there some fundamental best practices for URL structure and Link Building as it pertains to Topic Clusters?

Thanks!
