What's the minimum Google Ads budget that works in Cornwall?

For most Cornwall local trades and services, £500 a month on ad spend is the practical minimum. Add a management fee (we charge a fixed £400 a month, never a percentage of spend). Below £500 you don't get enough click data to optimise, so budget burns on keywords that don't convert. For competitive sectors like property, law, or emergency trades, plan for £1,000+ a month on spend.
