What the sampled data suggests

In this dated sample, personality and lifestyle categories had higher averages than housing. This describes the sampled legacy documents only.

In practical terms, better matching content should keep pushing on commute fit, guest expectations, room setup, and how shared space is used.

Why seeker-heavy demand matters

The sampled profile set is heavily weighted toward people looking for rooms or housemates rather than offering space. That reinforces the need for deeper lister-funnel SEO in Phase 2 and stronger content for listing creators.

How to read this report correctly

This is an aggregate historical snapshot, not a universal claim about renters, rooms, the current Synergy V4 pair read, or future outcomes.
