IES Brand Evaluation Framework: What It Measures and Why It Matters

The IES Brand Evaluation Framework assesses brand strength across three dimensions: Identity, Expression, and Salience. It gives strategists a structured way to diagnose where a brand is underperforming before committing budget to fix it. Most brand audits either go too deep into aesthetics or stay too shallow on commercial outcomes. IES sits in the middle, which is exactly where the useful work gets done.

If you have ever inherited a brand that looks coherent on the surface but produces inconsistent commercial results, you already know the problem this framework is designed to solve. The brand looks fine. The positioning deck is polished. But something is not connecting with buyers, and nobody can agree on what to fix first.

What Does IES Actually Stand For?

IES stands for Identity, Expression, and Salience. Each dimension captures a different layer of brand performance, and each one can fail independently of the others. That independence is the point. A brand can have a strong identity and weak salience. It can have clear salience in a category and completely inconsistent expression across channels. Treating brand health as a single score obscures which of these three problems you are actually dealing with.

Identity covers what the brand stands for: its positioning, values, personality, and the promise it makes to its audience. Expression covers how consistently that identity is communicated across every touchpoint, from advertising to customer service to the tone of an invoice. Salience covers whether the brand comes to mind in the right context, at the right moment, for the right reasons.

The framework is not proprietary to a single consultancy. It draws from decades of brand theory, including work on mental availability and category entry points, and it maps cleanly onto how most experienced strategists already think about brand problems. What it adds is structure and sequence.

If you want a broader grounding in brand strategy before applying this framework, the Brand Positioning and Archetypes hub covers the full strategic landscape, from positioning fundamentals to architecture decisions.

Why Most Brand Audits Fail Before They Start

I have sat through a lot of brand audits over the years. Some were rigorous. Most were not. The pattern I see most often is that audits are commissioned to validate a decision that has already been made, usually a rebrand that someone senior has already decided they want. The audit becomes a justification exercise rather than a diagnostic one.

The second failure mode is scope confusion. Teams conflate brand identity work with brand expression work and end up redesigning assets when the real problem is that nobody outside the company knows who they are. I saw this play out at a client in financial services several years ago. They had spent a significant budget on a visual identity refresh. The new brand looked genuinely good. But their target audience, mid-market CFOs evaluating treasury management software, had essentially zero awareness of them. The expression was cleaner. The salience problem was untouched.

IES forces you to score each dimension before you decide what to fix. That sequencing matters more than most people give it credit for. Wistia’s analysis of why brand building strategies underperform points to a similar root cause: teams invest in the wrong layer of the brand problem because they have not diagnosed the actual failure point first.

The Identity Dimension: What the Brand Claims to Be

Identity is the foundation. It covers the internal articulation of what the brand stands for: its positioning statement, its defined personality, its values, and the promise it makes to customers. A strong identity is specific, differentiated, and grounded in something the business can actually deliver. A weak identity is vague, generic, or aspirational in a way that has no operational backing.

When I was growing an agency from around 20 people to close to 100, identity was the thing we had to get right early. We positioned ourselves as a European hub with genuine multilingual capability, not as a generalist digital agency trying to do everything for everyone. That specificity was uncomfortable at first because it felt like it was closing doors. In practice, it opened the right ones. The identity gave us a clear filter for which clients to pursue and which to walk away from.

Scoring Identity in the IES framework involves asking four questions. Does the brand have a written positioning statement that a senior hire could recite without prompting? Is the brand personality defined in behavioural terms rather than abstract adjectives? Are the brand values operationalised, meaning do they influence actual decisions? And is the promise differentiated enough to be meaningfully owned in the category?

If the answer to any of those questions is no, you have an Identity problem. That does not mean you start there. It means you have identified a root cause that will undermine everything else if left unaddressed. HubSpot’s breakdown of brand strategy components covers the core elements that a well-defined identity should contain, and it is a useful reference for teams building out their scoring criteria.

The Expression Dimension: How Consistently the Brand Shows Up

Expression is where most brands leak equity. The identity can be perfectly defined and the salience can be building, but if the brand shows up differently across channels, audiences, or geographies, the cumulative effect is erosion rather than reinforcement.

Expression covers visual consistency, verbal consistency, and behavioural consistency. Visual consistency is the most obvious one: does the brand look the same on a paid social ad, a trade show stand, a pitch deck, and a product page? Verbal consistency is subtler: does the brand sound the same in a press release, a customer email, a LinkedIn post, and a sales call? Behavioural consistency is the hardest to measure: does the brand act in ways that are coherent with what it claims to stand for?

The challenge with Expression is that it degrades gradually. No single inconsistency destroys a brand. But the accumulation of slightly off-tone copy, slightly wrong-shade-of-blue assets, and slightly misaligned messaging across teams adds up to a brand that feels vague and untrustworthy without anyone being able to point to a specific cause. MarketingProfs on building a flexible brand identity toolkit addresses this directly, with practical thinking on how to maintain coherence without rigidity.

When I was managing a network of offices across multiple markets, Expression was a constant operational challenge. Each market had its own creative preferences, its own interpretation of the brand guidelines, and its own view of what the brand should prioritise. The answer was not a thicker brand manual. It was a clearer set of non-negotiables combined with genuine latitude on the things that did not matter. Teams will follow constraints they understand. They will ignore constraints that feel arbitrary.

Scoring Expression in IES involves auditing a representative sample of brand outputs across a defined period, typically 90 days of live content, and assessing consistency against three criteria: visual adherence, tonal adherence, and message adherence. The score is not about perfection. It is about whether the variance is within a tolerable range or whether it is systematic enough to be causing real confusion in the market.

The Salience Dimension: Whether the Brand Gets Recalled When It Counts

Salience is the commercial dimension. It asks whether the brand comes to mind in the right buying context, at the right moment, for the right reasons. This is different from awareness. A brand can have high awareness and low salience. People know it exists but do not think of it when they are actually making a purchase decision.

The distinction between awareness and salience is one of the most important and most consistently underappreciated in brand strategy. I have judged entries at the Effie Awards where brands could demonstrate high aided awareness scores but struggled to show any evidence that they were being recalled in purchase situations. Awareness is a vanity metric if it is not connected to category entry points.

Salience is built through consistent, distinctive, and contextually relevant communication over time. It is the dimension most damaged by inconsistent media investment, particularly the pattern of going dark for extended periods and then spending heavily in short bursts. BCG’s research on brand advocacy shows that brands with stronger mental availability tend to generate more organic word-of-mouth, which compounds salience over time without proportional increases in media spend.

Scoring Salience in IES draws on a combination of primary research, where budget allows, and proxy metrics where it does not. Primary research includes unaided recall in category, share of consideration, and category entry point mapping. Proxy metrics include branded search volume trends, direct traffic patterns, and share of voice relative to category spend. None of these are perfect. Together they give you a directionally reliable picture of whether salience is building, holding, or declining.

How to Run an IES Evaluation in Practice

The mechanics of an IES evaluation are straightforward. The discipline is in not skipping the parts that feel obvious.

Start with Identity. Collect all existing brand documentation: positioning statements, brand guidelines, values frameworks, tone of voice documents. Score each element on a simple three-point scale: defined and operationalised, defined but not operationalised, or not defined. Do not score aspirations. Score what actually exists and is being used.

Move to Expression. Pull a sample of brand outputs from the last 90 days across every active channel. Include paid, owned, and earned. Include internal communications if the brand makes internal culture claims. Score for visual consistency, verbal consistency, and message consistency. Flag systematic deviations, not one-off errors.

Finish with Salience. Map the primary category entry points for your audience. These are the situations, needs, and triggers that prompt consideration of your category. Then assess, using whatever data you have available, whether your brand is associated with those entry points in the minds of your target audience. This is the hardest dimension to score precisely, but the direction of travel is usually clear enough to act on.

Once you have scores across all three dimensions, prioritise interventions in order of commercial urgency, not ease of execution. The most common mistake is fixing Expression first because it is visible and tangible, when the actual constraint on growth is a Salience problem that requires sustained media investment to address. Moz’s analysis of brand loyalty drivers reinforces that point: the brands that build durable loyalty do so through consistent presence and relevance, not through periodic creative refreshes.

Where IES Fits in the Broader Brand Strategy Process

IES is a diagnostic tool, not a strategy tool. That distinction matters. Running an IES evaluation tells you where the brand is underperforming and at which layer. It does not tell you what the brand should stand for, who it should target, or how it should be positioned against competitors. Those are strategy questions that require a different process.

The right place for IES in a brand strategy process is at the beginning, before the strategy work starts. Use it to establish a baseline and identify the primary constraint. If Identity is the problem, the strategy work needs to start with positioning. If Expression is the problem, the strategy work can build on the existing positioning but needs to focus on governance and consistency systems. If Salience is the problem, the strategy work needs to focus on media and message, not on brand architecture.

IES also has value as an ongoing monitoring tool. Running a lightweight version of the evaluation annually, or after significant business events like a merger, a market entry, or a major product launch, gives you an early warning system for brand drift before it becomes a commercial problem. BCG’s work on aligning brand and go-to-market strategy makes the case for treating brand health as an ongoing operational metric rather than a periodic project, which is exactly the mindset IES supports.

For teams working through the full brand strategy process, the Brand Positioning and Archetypes hub covers each stage in detail, from audience research through to positioning, personality, and architecture. IES sits at the front of that process as the diagnostic that shapes every subsequent decision.

The Most Common Scoring Mistakes

Three mistakes come up consistently when teams apply IES for the first time.

The first is scoring Identity on aspiration rather than reality. Teams read their brand guidelines, see a well-written positioning statement, and give themselves a high Identity score. But if the positioning statement was written three years ago by an agency that no longer works with the business, and nobody on the current team could reproduce it without looking it up, the Identity score should reflect that. Documented but unused is not the same as operationalised.

The second mistake is sampling Expression too narrowly. Teams audit their paid advertising because it is easy to pull and looks polished, and conclude that Expression is strong. But the real Expression failures often live in sales decks, customer emails, partner communications, and social content produced by regional teams. A brand that looks consistent in its media spend but inconsistent everywhere else has an Expression problem that the audit has missed.

The third mistake is treating Salience as a single number. Salience is category-specific and audience-specific. A brand can have strong salience with one buyer persona and near-zero salience with another. A brand can be highly salient for one product category and invisible in an adjacent one it is trying to enter. Scoring Salience as an aggregate obscures these distinctions and leads to interventions that address the wrong audience or the wrong context. Moz’s examination of brand equity dynamics illustrates how salience can be concentrated in specific contexts and how quickly it can shift when those contexts change.

The fix for all three mistakes is the same: be more specific in your scoring criteria before you start the evaluation. Define what a high Identity score actually requires in operational terms. Define which channels and outputs are in scope for Expression. Define which audiences and category entry points matter for Salience. The framework is only as useful as the rigour you bring to applying it.
