Do I need both SEO and social media for my business?

You do not always need both, and it depends on how your customers actually find you. SEO puts you in front of people already searching for what you do, so it suits trades, professional services and anything people look up when they need it. Social media suits businesses people discover while browsing, like cafes, holiday lets, retail and anything visual. Most Cornwall businesses lean one way. If your customers search Google when they need you, put your first £500 into SEO and a good website. If they scroll and get inspired, start with one social channel. Doing both only makes sense once one is clearly working and you have the time or budget to add the other properly.
