Do marketing agencies provide ongoing support or just one-off projects?

One-off projects suit specific needs like website builds or rebrands with clear start and end points. Ongoing retainers cover continuous marketing operations like SEO and content creation. Companies with internal marketing use agencies for specialist projects, businesses without dedicated staff benefit from ongoing support. Hybrid arrangements combining both are common.

Marketing agencies typically offer both ongoing support and one-off projects, though some specialise in one approach over the other.

One-off projects suit specific needs: website builds, rebrand campaigns, market research, or launching a new product. These have defined start and end points with clear deliverables. The agency completes the work, hands it over, and the engagement ends.

Ongoing support works differently. Monthly retainers cover continuous services like SEO, content creation, social media management, and campaign optimisation. This model suits businesses needing consistent marketing operations rather than sporadic projects.

Many agencies, including Mumble Marketing, provide both options. A business might start with a one-off website build, then move to ongoing support for SEO and content. Or they might need ongoing social media management alongside occasional campaign projects.

The choice depends on business needs and resources. Companies with internal marketing capability often use agencies for specific projects or specialist services. Businesses without dedicated marketing staff typically benefit more from ongoing support that functions as their external marketing department.

Hybrid arrangements are common: a base retainer for core services with additional project fees for larger initiatives like website redesigns or major campaigns.
