Key Questions to Ask Before Making Your Decision

Before committing to any agency partnership, ensure you ask these critical questions:

• Can you provide three recent case studies with brands in the $1-10M revenue range?
• What’s your approach to incrementality testing and attribution beyond last-click?
• How do you integrate paid acquisition with lifecycle marketing and CRO?
• What’s your creative testing methodology and iteration schedule?
• How do you handle iOS updates and privacy changes affecting measurement?

For 7-figure brands specifically, prioritize agencies that can demonstrate experience with MER (Marketing Efficiency Ratio) optimization and contribution margin improvement. Metrics that matter more than channel-specific ROAS as you scale.

Maximizing Your Agency Partnership Success

The most successful 7-figure brands treat their agency relationship as a strategic partnership rather than a vendor relationship. Based on industry best practices, here are key factors for success:

Establish Clear KPIs: Move beyond ROAS to focus on blended metrics like MER, contribution margin, and customer lifetime value. The most effective agencies, like Single Grain’s specialized approach, structure their reporting around business outcomes rather than channel-specific metrics.

Invest in Testing Infrastructure: Agencies that excel with 7-figure brands implement structured testing across creative, audiences, landing pages, and email flows. This requires both agency expertise and sufficient budget allocation for meaningful test periods.

Plan for Seasonality: E-commerce marketing performance varies significantly throughout the year. The best agency partnerships involve proactive planning for Q4, post-holiday optimization, and summer scaling strategies.

The choice of marketing agency will significantly impact your ability to scale from 7 figures to 8 figures and beyond. Work with the most innovative marketing agency to discuss your specific challenges and develop a customized growth strategy that positions your brand for sustainable, profitable scaling.
