How often should a Cornwall small business post on social media?

Three to five times a week per platform is the realistic floor for organic reach. Less than that and the algorithms stop serving your content to existing followers, let alone new ones. More than that and you'll burn out or post filler that hurts engagement. If you're doing this yourself, pick one platform that actually matches your customers (Instagram and TikTok for tourism and hospitality, LinkedIn for B2B services, Facebook for local trades) and commit to three posts a week for six months before adding a second platform. If you can't sustain that, managed social media starts at £350 a month across one platform with three posts a week and full community management.
