The challenge
Losing market share without knowing why
The brand was watching competitors capture an outsized share of the premium women's activewear market. Names they tracked closely — including several DTC-native brands and established athletic labels — were growing faster, generating more social conversation, and winning loyalty among demographics the brand had historically owned.
The team had hypotheses about why. They suspected shifts in consumer demographics and evolving product preferences, but their data didn't support or refute those hypotheses at any meaningful level of detail. Their existing approach combined paid syndicated data with manual scraping of review sites — a process that produced low volume, lagging data, and no ability to benchmark competitor products at the aspect level. They could see that a rival's legging had a 4.6-star rating. They could not see why consumers loved it, which specific features drove the rating, or how that compared to their own products attribute by attribute.
Without that granularity, every product decision was a bet. The merchandising team was guessing at what features to prioritize. The marketing team was guessing at which consumer segments to target. The competitive intelligence team could track share-of-voice but couldn't explain share-of-preference.
The solution
Comprehensive review aggregation and aspect-level competitive benchmarking
Merciv's Research capability was deployed to build a competitive intelligence picture that the brand's existing tools simply couldn't produce.
Large-scale review and sentiment aggregation
Merciv aggregated upwards of 10,000 recent product reviews across the brand's own products and five key competitors, alongside consumer sentiment from Instagram, TikTok, and Reddit. This wasn't a sample — it was comprehensive coverage, capturing the full range of consumer voice across the competitive set.
Aspect-based competitive analysis
The platform analyzed every review and social mention at the aspect level, extracting sentiment by percentage around individual product attributes: fit, fabric quality, durability, pocket design, waistband construction, size inclusivity, pricing perception, and styling versatility. For the first time, the brand could see exactly where competitors scored higher on specific attributes — and where the brand's own products had unrecognized strengths.
Demographic and psychographic profiling
Beyond product features, Merciv conducted granular demographic analysis to map exactly who the brand's consumers were — and who competitors' consumers were — across psychographic, behavioral, and geographic dimensions. This profiling revealed not just what consumers wanted, but who wanted it, where they were, and how they made purchasing decisions.
The results
One concrete unmet demand identified with precise demographic targeting
The competitive analysis revealed a clear, actionable finding: consumers across the competitive set were consistently praising pocket structures in leggings — specifically, zippered and secure pocket designs that competitors had introduced to strong reception. The brand's legging line lacked this feature entirely.
- 10,000+ reviews analyzed across the brand and 5 competitors
- Aspect-level sentiment mapped across 8+ product attributes per brand
- 1 concrete product innovation identified: secure pocket structures in leggings
- Full demographic profile built to inform launch targeting — psychographic, behavioral, and geographic
- Competitive proof points established showing exactly which rival features were driving consumer preference
The brand's product team used the finding to inform the development of a new legging with the pocket features consumers were requesting. The marketing team used the demographic and psychographic profiling to build a targeted launch strategy that spoke to the specific consumer segments most likely to respond. Rather than launching to a broad audience with a generic message, they launched to a defined audience with a message shaped by actual consumer language.
“We had assumptions about our consumer. Merciv gave us proof. The pocket insight alone justified the engagement — but the demographic clarity is what changed how we think about every launch going forward.”

Key takeaway
Competitive intelligence at the aspect level changes product decisions
Star ratings and share-of-voice are lagging indicators. By the time a competitor's product has a high rating and strong social presence, the opportunity to respond has narrowed. Aspect-level competitive analysis reveals the reasons behind those ratings — the specific features, experiences, and attributes driving consumer preference — while there's still time to act.
In the activewear category, where product cycles are measured in seasons and consumer preferences shift with cultural trends, the brands that can identify unmet demand at the feature level will consistently outmaneuver rivals who are still reading top-line ratings. The gap between “we know our competitor is rated 4.6 stars” and “we know why they're rated 4.6 stars, and we know the one thing they're missing” is the gap between following the market and shaping it.
Frequently asked questions
Merciv aggregates thousands of product reviews and social mentions across a brand and its competitors, then applies aspect-based sentiment analysis to reveal exactly which product attributes — fit, fabric, features, pricing — are driving consumer preference at a granular level, far beyond what star ratings or share-of-voice metrics can show.
Aspect-based review analysis breaks down consumer reviews into individual product attributes (such as durability, pocket design, or size inclusivity) and measures sentiment for each attribute separately, enabling brands to identify specific strengths and gaps rather than relying on aggregate ratings.
By analyzing thousands of reviews across a competitive set, brands can identify specific unmet consumer demands — features competitors offer that they don’t, or features no competitor offers yet — and use validated demographic profiling to build targeted launch strategies for new products.
