The right setup depends on what the target watches for. A retail price sweep and a social profile session need opposite things from a proxy: one wants a new address on every request, the other wants the same address for hours. These pages cover both per site.
Catalogue, price and stock data that changes by region and by the hour. Rotating residential suits the sweep; the exit country decides which catalogue you see.
Rate limits per address are the binding constraint, and trending content is localised. Rotating for collection, sticky when a session has to look continuous.
High demand windows where inventory moves in seconds and regional catalogues differ. Frequent polling from one address is the fastest way to get blocked.
SERP data is personalised and localised, so the exit location changes the result set more than any other factor.
If you are choosing a rotation mode or a tool rather than a target, these cover the other two axes.
