Product Studio Research
Product Studio Research is a private, internal tool used by one small UK business to plan its own printable digital products. Once a week it asks Google Ads Keyword Planner which search phrases people use and how often, so the business can decide which products are worth making.
It is not a public service: there are no user accounts, no sign-ups, and no one outside the business uses it. It only reads keyword data for the business's own Google Ads account.
