The two-signal framework
Trendier doesn't infer trends from press coverage or social media. Every trend comes from marketplace data, analyzed across two signal streams: supply and demand.
Supply-side signals — what brands are doing
New product launches
Changes in PDP (product detail page) language
Price movements and promotion patterns
Ingredient adoption trends
Marketing keyword patterns
Demand-side signals — what consumers are saying
Rising or falling review keywords
Sentiment shifts (positive or negative)
Emerging benefit claims
Unmet needs surfaced in reviews
When both sides move in the same direction, Trendier flags it as a trend. The same methodology powers AI Chat answers, Library reports, and Generator outputs.
White space detection
When rising consumer keywords aren't reflected in brand marketing or PDPs, that's a white space — a messaging or product opportunity. Detecting it requires both signal streams at once.
Three ways to access trend detection
Ask AI Chat: "Which keywords are rising in niacinamide reviews on Amazon US?"
Read a Library report on a category
Generate a custom trend or white space report
Common follow-up questions
How quickly are trends detected?
Trendier collects e-commerce data in real time — purchases, reviews, PDP updates. Trends surface earlier than in press or social media.
Does the methodology work the same in every market?
Yes. The two-signal framework runs across all 32+ channels. Source signals differ by channel — review platforms, PDP layouts — but the method is the same.
How is this different from traditional market research reports?
Traditional market research publishes quarterly or annually, based on surveys or panels. Trendier runs continuously on live transaction data, so trends surface in real time.
