What's the difference between a marketing agency and an advertising agency?

Marketing agencies handle strategy, branding, lead generation, and ongoing growth operations. Advertising agencies specialise in creating and placing paid campaigns across specific channels. Most businesses need the strategic foundation first, then bring in advertising expertise for major campaigns when needed.

The main difference is scope and focus. Marketing agencies take a holistic approach to growing your business - strategy, branding, content, digital presence, and lead generation. Advertising agencies specialise in creating and placing paid campaigns across specific channels like TV, radio, print, or digital ads.

Marketing agencies typically handle ongoing operations: building your brand, generating leads through multiple channels, creating content, managing websites, and supporting sales. They might run some ad campaigns as part of the mix, but it's not their sole focus.

Advertising agencies are dedicated creative specialists. They excel at campaign concepts, copywriting, design, and media buying. If you need a major campaign launch or sophisticated creative work, an ad agency might be the right call. For ongoing business growth, lead generation, and market presence, a marketing agency makes more sense.

Many businesses start with a marketing agency for the strategic foundation, then bring in advertising expertise for specific campaigns when needed. Mumble Marketing focuses on the marketing side - brand positioning, digital presence, and sales operations for businesses across Norfolk and the UK.
