“Everyone in Cornwall” is a geography, not a useful customer definition. Most businesses need a smaller group with the right need, catchment, timing and value. Broad reach can build fame, but it should be a deliberate strategy – not the default justification for an expensive placement.
Why county-wide reach sounds attractive
A large audience is easy to present and compare. It feels safe because no potential customer is deliberately excluded. But marketing budget is finite. Paying to reach people who cannot buy, will not travel or have no current interest carries an opportunity cost.
A Truro kitchen showroom, a Penzance restaurant and a county-wide professional adviser have different practical markets. The first may value high-intent property projects within a serviceable radius, the second needs nearby diners at specific times, and the third may genuinely serve organisations across Cornwall.
Define four boundaries before buying media
| Boundary | Question | Example |
|---|---|---|
| Need | What problem must exist? | Planning a kitchen replacement |
| Catchment | Where can we serve profitably? | Within realistic survey and installation coverage |
| Timing | When is the person receptive? | Researching suppliers in the next six months |
| Value | Which outcomes justify acquisition cost? | Qualified project, not any website visit |
Digital targeting is powerful, not perfect
Search can capture an expressed need. Location settings can narrow physical presence or include interest in Cornwall. Paid social can use geography, audience signals and previous engagement. Email can reach a lawful first-party audience. None of these tools reads minds or identifies every customer correctly.
Google explains that location targeting uses multiple signals and is a best effort, not 100% accurate. Small audiences can also become expensive, unstable or overly dependent on platform inference. Use targeting to improve relevance, then judge real lead quality.
When broad reach is justified
- A mass-market offer genuinely available across Cornwall.
- A launch that needs category or brand awareness before demand exists.
- A long buying cycle where recognition compounds over time.
- A creative idea strong enough to earn attention beyond current intent.
- A measurement plan that includes brand and commercial indicators.
Broad reach is not wrong; it is a different job. Separate brand-building budget from immediate demand capture so one is not judged by the other’s timeframe while both remain accountable to the business.
Build a useful audience brief
- Name the customer situation, not only age and postcode.
- State who is deliberately excluded and why.
- Describe the decision and its likely timing.
- Choose channels that can reach that moment.
- Set a frequency guardrail where possible.
- Measure qualified response and incremental effect.
- Review whether the audience definition predicted real customers.
Casale’s fractional marketing director service in Cornwall helps businesses make these choices across the whole plan, rather than optimising disconnected channels.
Frequently asked questions
Is a larger audience always cheaper?
The cost per thousand may be lower while the cost per relevant customer is higher. Compare the audience that can realistically act and the resulting commercial outcome.
How narrow should Cornwall targeting be?
Narrow enough to reflect serviceability and intent, but large enough to learn and deliver. Search terms and sales data should refine the boundary over time.
Can print target a niche Cornwall audience?
Yes, when the publication, section, distribution context or reader relationship is genuinely relevant. Ask for transparent evidence rather than assuming every reader is equal.
