# Data Definitions

## Several Analytic Index specific metric definitions

**Search Visibility Score** A composite metric used to estimate how often this product/brand/category was viewed in shopper searches. It is estimated using the number of keywords, search volume, item search rank, and number of days items appeared in the search result slots.

**Organic Search Visibility**: A composite metric used to estimate how often this product/brand/category was viewed in shopper searches. It is estimated using the number of keywords, search volume, item **organic** search rank, and number of days items appeared in the search result slots.

**Sponsorship Activity:** Sponsorship activity measures the number of sponsored item occurrences by day and keyword. For example, an item that appeared as a sponsored result in 3 keywords for 2 days and 4 keywords for 1 day would contribute 3\*2+4\*1=10 to this sponsorship activity.

**Keyword Opportunity Score:** Keyword Opportunity Score is a way to prioritize a keyword list based on the combination of Search Volume and the Relevancy Score (according to the retailer's search algorithm) of that keyword to the brand, item, or category. *Opportunity Score = Search Volume x Relevancy Score*

**Category Sales Share:** Analytic Index provides sales share estimates for each department and its categories. These estimates are based on a number of factors including retailer reported item sales rank data of the top sold products in each category, machine learning models trained from actual sales data (note that clients are not required to contribute any data to train models as this is purely an opt-in training set from strategic client partners), and external industry data sources. Analytic Index uses all of this data and trains algorithms to create our sales share estimates in the form of market share percentages for each category. When multiple categories are summed, total share estimates are weighted according to relative category depth. Share of sales estimates can not be aggregated across different departments at this time.

**Amazon Search Volume Estimates:** We estimate Amazon Search Volume with a statistical model that uses inputs from Amazon Brand Analytics, our own Amazon crawl, and external data on Amazon-related searches. These inputs include keyword search frequency rank, some known data on keyword search volume (collected from Amazon), and known search volume in the ecommerce marketplace.

Data for the prior week usually comes in on Wednesday.
