Should a Cornwall small business use Facebook ads or Google ads?

It depends on whether people are already looking for you. Google ads catch people at the moment they search for your service, so they suit trades and services with clear demand, like emergency plumber Newquay. Facebook and Instagram ads interrupt people while they scroll, so they suit visual, impulse or discovery businesses like holiday lets, events and retail. For most Cornwall service businesses, Google ads convert better because the intent is already there. For anything visual or brand-led, social ads build awareness more cheaply. A sensible test budget for either is around £300 over a few weeks, tracked properly, and you scale only what turns into real enquiries rather than just clicks and likes.
