Hiring Guide: How to Choose Top Digital Marketing Agencies in the US

What can a US digital marketing agency do for businesses?

A US digital marketing agency can help businesses drive sustainable growth by turning digital strategies into measurable revenue and long-term competitive advantages.

Beyond creating and executing campaigns, these agencies align strategies with business objectives and ensure that all channels support the same goals, delivering consistent, coordinated experiences to customers.

This integrated approach is critical in an omnichannel environment.

McKinsey reports that 80% of customers use multiple channels to research and buy a product, with the average B2B sales journey involving 10 touchpoints.

By centralizing strategy, execution, and performance measurement, digital marketing agencies help businesses scale efficiently while reducing internal complexity.

How much do US companies typically invest in digital marketing?

US companies, on average, invest 7.7% of their annual revenue in digital marketing.

Out of this percentage, 25-55% goes to demand capture media, including search, shopping, and retargeting campaigns.

10-35% is allocated to demand creation media, such as paid social, prospecting, and sponsorships.

5-15% is dedicated to customer relationship management (CRM) via email marketing and loyalty programs. Meanwhile, 5-10% is for conversion rate optimization (CRO) and website optimization.

Lastly, 8-20% is allotted for creative production, 5-10% for data analytics, and 10-20% for agency fees and marketing tools.

What digital marketing channels deliver the highest ROI?

SEO also delivers powerful long-term ROI, capturing high-intent demand and supporting performance across other channels. On average, this channel has a 748% ROI.

Influencer marketing can produce high returns for industries where trust, authority, and audience alignment are crucial, with an ROI averaging at 578%.
