What is Share of Voice (TV)?
Share of Voice (SoV) in TV advertising represents your brand's advertising investment as a percentage of the total advertising spend within your category during a specific period. If your category spends £10 million on TV advertising and your brand spends £2 million, your SoV is 20%.
Why Share of Voice Matters
SoV is a critical competitive benchmark in UK television advertising. It directly correlates with brand awareness, consideration, and ultimately market share. Research consistently shows that brands with higher SoV achieve greater brand recall and purchase intent than competitors with lower SoV.
Unlike absolute spend figures, SoV contextualizes your investment relative to competitor activity. This is particularly important in the UK market, where media costs fluctuate seasonally and category spending varies significantly by sector.
How SoV Works in Practice
SoV is calculated across:
- Time periods: Weekly, monthly, or annually
- Geographic markets: UK-wide, regional, or specific ITV regions
- Demographic segments: Total viewers, ABC1, 25-54s, etc.
- Dayparts: Peak, off-peak, or specific programming slots
A brand might have 15% SoV among ABC1 audiences but only 8% SoV among all viewers, indicating their spend is concentrated in premium dayparts.
When to Use SoV
SoV is essential for:
- Competitive analysis and benchmarking against named competitors
- Justifying media budget allocation to stakeholders
- Setting realistic awareness targets (higher SoV typically drives higher awareness)
- Identifying market gaps where competitor activity is low
- Planning campaign intensity and frequency
- Evaluating campaign performance against category dynamics
SoV vs Market Share
A common misconception is that SoV should equal market share. In reality, brands often operate at SoV-to-market-share ratios of 1.2:1 or higher, meaning they spend more than their market share warrants. This "over-indexing" protects against competitive erosion and drives growth.
UK-Specific Considerations
In the UK, SoV analysis is complicated by:
- Regional variation across ITV franchises and Freeview coverage
- Multi-channel fragmentation reducing traditional TV's dominance
- The need to consider SoV across integrated channels (TV + VOD + digital)
- Seasonal peaks (Christmas, summer holidays) when category spending surges
Measurement
SoV is tracked through media intelligence tools such as Nielsen, Kantar, and Mediavest, which monitor advertising spend across broadcast channels. Connect Media Group uses these insights to benchmark your campaigns and optimize spend allocation.
