What is the difference between the MarketBase, Acquire, Enrich and Refresh capabilities

There are currently three capabilities: Acquire, Enrich, and Refresh.  Each has different uses:

  • Acquire allows you to purchase data based upon flexible search criteria, right from within MS Excel.  You can acquire either Company or Contact records.  Contact Basic is a full record without an email, whereas Contact Complete is a Basic record + email.
  • Enrich has two stages:
    • Step 1 Match and Append which allows you to append the MarketBase record ID and basic information about a company at no charge. For best results use the Company Name and Address to avoid returning unnecessary record matches.
    • Step 2 Enrich uses either the MarketBase Company ID and/or Site ID to retrieve the Company’s additional data, see the Enrich page for a complete list of attributes appended.
  • Refresh also uses the MarketBase ID’s for either Company or Contact data refreshes.
      • (Note: with the correct refresh criteria, only data that has changed since the last refresh will be charged.

Why is MarketBase a market lading source of data

“MarketBase leverages Experian’s BusinessView reference data, which is the result of Experian’s extensive expertise in acquiring, analyzing, and consolidating prominent B2B datasets from the UK, Ireland, and other regions for nearly four decades.

MarketBase embodies three key principles:

  1. Comprehensive Coverage: It strives to encompass as many businesses within the UK market as possible.
  2. Diverse Data: It aims to maximize both the quantity and variety of information available for each company.
  3. Data Integrity: Utilising sophisticated validation methods developed over years, it efficiently identifies and eliminates inconsistent or inaccurate data, ensuring data reliability and accuracy.”
What sources of data make up MarketBase

In the UK in particular, the range of commercially available sources includes:

  1. Government databases (for example Companies House, Register of Charities), this is there for official company registration purposes and the filing of accounts and other company documents.
  2. Open government data (for example, FSA, Council data, Licensed premises data) is available under the terms of the Open Government License.
  3. Online Business Directories (for example Thomson, 118 information), where the primary aim is exposure to customers and therefore reliable in terms of contact information).
  4. Specialist databases (for example Infynd, Veridion, Corpfin), which focus on gathering multiple contact information for all businesses in the market, and sometimes with specific depth of data such as fleet or M&A information.
  5. Web-harvested information helps to validate other data sources as well as provide detailed information rarely found elsewhere.

The data collected by us is the foundation of the goods and services we offer and, as with the combination of data sources, the combination of individual items of information and human analytics can create data outputs for specific use cases (such as modeling, segmentations) which are more powerful than the individual items provided by our suppliers.
