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, plus 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 the campaign, so budget gets burned on keywords that don't convert. For competitive Cornwall sectors like property, law or emergency trades, plan for £1,000+ a month on spend. Hospitality and tourism businesses often see strong ROI at £500 to £800. Within 60 days you should expect CTR to lift from around 2% to 6-10% as we kill the losing keywords, and cost per enquiry to drop by 30-50%.
