Local vs national: how reach changes a social budget

Key takeaways

A local vs national social media budget differs mainly because of audience size. A local business targeting a few miles can reach most of its buyers on £300–£800 a month of ads. A national business faces a bigger audience, more competition and more testing, so it usually needs £1,000 or more.

• £300–£800 a month in ads covers most local radius targeting.
• £1,000+ a month is a common floor for national campaigns.
• Small local audiences tire of ads faster, so refresh creative.
• National budgets must fund more testing before scaling.

Why can a local business spend less?

A tight radius limits how many people you can usefully reach. Once a budget reaches most of them a few times a week, extra spend mostly shows the same ads to the same people. Local businesses also benefit from word of mouth and Google searches that national advertisers cannot rely on.

Why does national reach cost more?

A national audience is large, so the platform needs more spend to find the best buyers within it. Competition is wider, because you bid against every business selling to the same people. National offers also need more testing of messages and audiences before you know what works.

• Targeted vs mass advertising: paying only for likely buyers

How do you tell when a local budget is too big?

Watch frequency, the average number of times each person sees your ad. When it climbs well above three or four a week and results fall, the audience is saturated. Widen the radius slightly, refresh the creative, or reduce spend rather than pushing harder.

• Is your audience big enough for your ad budget?
• Advertising frequency: how many times must people see an ad?

What if you serve several towns?

Treat each area as its own small budget if the offer or demand differs, or combine them if they behave alike. Splitting too finely leaves each area with too little spend to learn. Start combined, then separate the areas whose cost per enquiry differs clearly.

• Multi-location social media management costs

What does this look like in practice?

A pattern we see: a local business copies a national brand's daily budget and shows the same ad to its small town eight or ten times a week. Cutting spend and refreshing creative monthly usually keeps the same enquiry volume at a lower cost.

Check your current campaign's weekly frequency and audience size. If frequency is high and results are falling, the budget is larger than the area can absorb.
