Marketplace fill rates

Every Bright Data Marketplace dataset page exposes field-level fill rates in the Fill rate column of the Dictionary tab, alongside the total record count and a freshness indicator; the Statistics tab holds dataset-level charts. Review these before purchase to confirm the dataset meets your requirements.

​

What are fill rates?

A fill rate is the percentage of records in a dataset where a specific field is populated. A fill rate of 100 percent means every record contains a value for that field. A lower fill rate means some records are missing values for that field. Fill rates vary depending on:

• The dataset type (social media, B2B, eCommerce)
• The source quality and what is publicly available
• The specific field being measured (email, phone number, location)

​

Where to find fill rates

Fill rates and statistics are shown on each dataset’s page in the Marketplace.

​

What statistics are available?

For each dataset you can review:

• Fill rate per field: percentage of records with a value
• Record count: total number of available records
• Freshness: how recently the data was collected

​

Why do some fields have low fill rates?

Some fields have lower fill rates because of limitations or gaps in the publicly available source data. For example, phone numbers and email addresses are not always publicly listed, so contact fields commonly show lower fill rates than name or location fields.
