The Shelf Signal
Methodology

How a trend gets scored, and how it gets judged.

Two different things. The score is arithmetic you can check. The verdict is an operator's call, dated and kept on the record.

Signal score

0 to 100, from six inputs

Recomputed nightly and whenever the editor adds a call or an article. Every trend page shows the inputs, not just the total.

Forecaster consensus

10 points per separate forecaster naming the trend. A retailer's annual list, a trade-association panel and a research report each count once.

40 pts
Recency

15 if the newest forecaster call is under 90 days old, 9 under 180, 5 under a year, 2 after that.

15 pts
Press volume

3 points per linked article in the last 90 days, capped at 15.

15 pts
Search momentum

Google Trends (US) when available, otherwise Wikipedia daily pageviews for the trend's articles, last 90 days. Up to 9 points for the last four weeks against the eight before, up to 6 for the level of interest. The trend page says which source was used.

15 pts
Social velocity

Reddit threads across the grocery and food subreddits in the last 30 days against the 30 before, plus new YouTube videos. Volume and growth each count.

10 pts
Products on shelf

Published products tagged to the trend: 1 point each at Scaling or Established, half a point at Emerging, capped at 5. Stage is distribution reach, with the evidence and date recorded. The weight rises as the product library grows.

5 pts
Shelf verdict

Real, Niche or Fad

Never automatic. The verdict is made by an operator who has merchandised, priced and sold the category, carries two lines of reasoning and a date, and every past verdict is kept so the quarterly scorecard can show the record.

Real

Will earn and hold shelf space across formats and price points. Worth building assortment, menus and launches around.

Niche

Durable, but for a defined shopper or channel. Stock it where that shopper is; don't bet the planogram on it.

Fad

Press and launches outrun repeat purchase. Expect the velocity to fall before the next reset.

On the radar

On the radar. Enough forecasters or press to track, not yet enough product or sell-through to call.

Momentum

Where the press is going

The sparkline is six months of linked press mentions. Rising means the last two months beat the two before; Steady means they matched; Cooling means they fell; Quiet means no recent coverage.

Press momentum is descriptive. Search and social are scored, but together they are a quarter of the total: a quiet trend with four forecasters behind it still outranks a loud one with one. When talk runs well ahead of forecaster and product support, the trend is tagged Talk ahead of shelf and surfaces on the Buzz Board.

Sources and editorial loop

Who we track, and who tags

Retailer forecasts (Whole Foods Market, Kroger), the Specialty Food Association's Trendspotter panel, Expo West and Fancy Food Show coverage, research houses such as Tastewise, and the trade press (Grocery Dive, BevNET, Nosh, FoodNavigator, Supermarket News, The Shelby Report).

Nothing publishes without a human tag. Trend calls and articles come in through an editorial desk and a weekly assisted scan; each call is credited to its forecaster with a source link.
