Why the page charts Google Shopping
A membership band people buy should be tracked on a shopping source first, and Google Shopping for whoop clears the 30-day +25% bar while Google Search for the same keyword fails both the 7-day and 30-day windows from a 74 print. Google Search for whoop is 74 on August 29, down 1.33% from 75 on August 22 and down 11.9% from 84 on August 1. The 7-day print fails +20%. The 30-day print fails +25%. Search is a high, stuck query after the May peak. Shopping is the cart. Amazon for whoop is stale at July 31, 74.1, down 3.01% from 76.4 on June 30, so it is not the story source.
Google Shopping is the story source: 41 to 41 in the frozen weekly series over 7 days, 16 to 41 in 30 days, 261 weekly points, week-to-week sample standard deviation 36.18% on the last 52 changes. Same-day get_growth on google shopping, 30-day window, puts garmin fenix at 61 (+408.33% from 12), apple watch at 19 (+46.15% from 13), oura at 11 (+37.5% from 8), and fitbit at 14 (0.0% from 14). Fitness context: Strava. Source context: Google Shopping trends.
get_time_series with source google shopping and keyword whoop is the call behind the chart. get_growth on the same pair, windows 7D and 30D, is the headline math: 41 to 41 (0.0%) and 16 to 41 (+156.25%). Mixing the Google Search 74 with the Shopping 41 would invent a story the APIs do not tell.
