In Episode 94 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked about the number of tiers that are allowed when setting up a non-video network.
The exact question was:
How deep can I setup my rss (non-video) networks? Tier 3? Tier 4? My Tier 2 are well themed and all running independent rss feeds slow drip? Or would it be better just to juice the Tier 2 networks? Also, about interlinking between networks if they are same people where a person would be on a separate Tier 2 network and company on Tier 1 network… Muchas Gracias!
