What marketplace research is really trying to preserve
The value of seller and assortment research comes from seeing the marketplace in a way that still resembles the public buyer experience. That means the proxy model has to support regional visibility, stable enough page loading, and clean session handling without turning the job into a generic technical crawl.
When the target is pricing, seller positioning, assortment coverage, or listing differences by region, the proxy choice should protect those public signals. If that protection is weak, the research can look complete but still point the team toward wrong conclusions.

Where stable identity matters and where it does not
Broad public research normally benefits more from residential visibility than from one fixed account-style identity, although some supporting workflows may still need narrower continuity. Stable identity becomes more important when the workflow includes browser profiles, account continuity, or a narrower operational pattern.
For broader marketplace observation, flexibility often matters more than one persistent identity. That is why the guide should keep research and account-management logic separate even when both support the same business team.

How to scale research without lowering signal quality
Scaling should prioritize repeated snapshots of important categories, sellers, and regions rather than uncontrolled request growth. Scale should increase only after the first region set and first result set both look trustworthy.
At that point, the guide should feed the commercial pages that match the winning model and create internal links to adjacent marketplace, GEO, and product-comparison guides.
