Introduction to Share of Voice (SOV) and Excess Share of Voice (ESOV)

The episode delves into the concepts of Share of Voice (SOV) and Excess Share of Voice (ESOV), foundational metrics in modern marketing that correlate advertising spend with market share growth. Elena Jasper introduces the topic by setting the stage for a comprehensive discussion on these metrics, emphasizing their relevance in today's fragmented media landscape.

A Historical Perspective on Share of Voice

Rob DeMars provides a nostalgic history lesson on SOV, tracing its origins back to the era dominated by TV, radio, and print media. He explains:

"Share of voice became the go-to way to measure how loud your brand was shouting compared to everyone else in the room. If your brand accounted for 25% of the ad spend in your category, you had 25% share of voice." (02:06)

Rob highlights how SOV served as a scoreboard for visibility and competitive presence, enabling marketers to justify their spend in terms the C-suite could understand. Despite the evolution of media channels, he asserts that the core idea of SOV—ensuring proportional visibility—remains timeless.

Understanding Excess Share of Voice (ESOV)

Angela Voss introduces ESOV, expanding on its definition and significance:

"ESOV is the difference between your share of voice and your share of market. For every 10-point increase in ESOV, brands typically see around a 0.5% annual market share growth on average." (05:04)

She references the foundational research by Les Binet and Peter Field, emphasizing ESOV's role in predicting market share growth. Angela underscores that ESOV is a practical tool for setting budget levels aligned with growth ambitions, reinforcing the principle: "Spend more than your fair share and generally you're likely to grow; spend less and risk a decline."

Debating the Relevance of ESOV in a Fragmented Media World

Elena introduces a critical perspective by referencing an article by Bhavan Pavari titled "ESOV: An Excessive Focus on the Wrong Thing." The article questions the reliability of ESOV in today's media landscape, where attention is fragmented, digital impressions are cheap and often meaningless, and creative content may be ignored or conversely, overly saturated.

"Bhavan makes the case that fame and creative cut through, not just budget are what truly earn attention and by extension market share." (06:18)

Angela Voss responds by acknowledging the validity of these critiques but maintains that ESOV remains robust when combined with strong creative and high-attention media environments. She notes:

"ESOV still works, but only when paired with the right message, the right media context." (06:18)

Angela emphasizes that ESOV has evolved from a straightforward spend comparison to a complex interplay of creative quality, media attention, and strategic message placement.

Calculating ESOV: The Complex Math Behind the Metric

Dan Cleveland delves into the intricate process of calculating ESOV, describing it as "fuzzy math" due to the imperfect nature of real-world data:

"It's not something where you're going to put like an R value on it to understand the exact tightness of that fit relationship... It tells us that we're spending either about enough or maybe not enough." (13:52)

He outlines the multiple dimensions involved:

1. Share of Voice Data: Aggregated through partners like Vivix, analyzing the competitive set's ad spend.
2. Engagement Metrics: Utilizing Google Trends to gauge brand engagement relative to competitors.
3. Brand Awareness Studies: Conducted periodically to assess aided and unaided awareness.
4. Market Share Data: Sourced through industry studies or proxies like credit card data where direct data is unavailable.

Dan explains the interrelationship between these metrics, noting that ESOV serves as a diagnostic tool to reveal underlying issues in marketing effectiveness, such as poor media mix or weak creative.

The Persistent Relevance of ESOV Amidst Media Fragmentation

Addressing concerns about media fragmentation, Dan argues that ESOV continues to provide valuable insights:

"Brands still are faced with the problem of deciding what to spend. If you were to say, take ESOV out of the equation, you still have that now, what are you going to use to understand your spend levels?" (15:45)

He asserts that while digital media complicates the landscape, ESOV remains a critical component in multi-model marketing strategies, offering a unique perspective that other tools cannot fully replicate.

Enhancing ESOV with Share of Search

Elena introduces the concept of Share of Search as an additional metric that complements ESOV. Dan elaborates:

"Share of search is designed to show that cause and effect. So that spend level versus what you're getting from an engagement level is really that first peek into marketing effectiveness." (17:45)

Share of Search leverages Google Trends data to provide real-time insights into brand engagement, enabling marketers to detect trends and adjust strategies more dynamically than traditional brand studies or market share data alone.

Practical Implications for Marketers

The discussion shifts to practical steps marketers can take to implement ESOV effectively:

Angela Voss emphasizes the importance of using ESOV to drive predictable growth:

"It's a starting point versus just an endpoint." (07:50)

Dan Cleveland outlines actionable steps:

1. Access Category Spend Data: Essential for establishing a baseline.
2. Project Category Trajectory: Understanding future spend and competitive positioning.
3. Monetize ESOV: Linking additional spend to expected market share growth.
4. Analyze Past Outcomes: Identifying trends and adjusting strategies accordingly.

Angela adds that marketers should aim to actively drive growth by setting realistic ESOV goals aligned with their brand ambitions and market conditions.

Risks of Underspending: Ensuring Share of Voice Aligns with Market Share

Angela Voss warns of the dangers associated with underspending, where a brand's SOV falls below its market share:

"You are inviting that decline. Brands that underspend relative to their market share tend to lose mental availability, making them forgettable and easily ignored." (20:28)

She highlights the long-term consequences, including weakened pricing power and increased price sensitivity among consumers, which can lead to margin erosion.

Future Directions: Integrating ESOV with Advanced Marketing Models

Looking ahead, Dan Cleveland shares Marketing Architects' plans to integrate ESOV with advanced attribution models and Marketing Mix Models (MMM):

"Blending this with our advanced attribution or MMM types of projects allows us to bend the curve, getting a more realistic picture of likely monetization." (24:01)

This integration aims to enhance predictive accuracy by incorporating real-time marketing effectiveness data, moving beyond historical trends to anticipate and influence future outcomes.

Practical Tips for Applying ESOV in Brand Strategy

As the episode concludes, practical advice is offered to marketers seeking to apply ESOV principles:

Angela Voss suggests:

• Establish Baselines: Secure access to share of voice and market share data.
• Set Growth Targets: Align ESOV goals with revenue ambitions.
• Optimize Impressions: Focus on quality over quantity to maximize the impact of ad spend.

Rob DeMars adds:

• Maintain Distinctive Assets: Ensure brand messaging stands out in a crowded marketplace.
• Select Effective Media Channels: Prioritize channels that offer high engagement at lower costs.
• Consistency is Key: Avoid erratic advertising patterns to maintain brand presence and recall.
