Top 5 Things You Should Know About Data Vendors

qualities of data vendors for leads

  1. Price per lead. When you are looking at ways to find sales leads, make sure you know the price per lead and compare these. You will find varieties based on industry, qualifications of the lead, and the process each data vendor uses.

  2. Data points. The best way to market and sell a prospect is to identify information about who they are. This should include basic demographics. It should also include countries you want to target. If you want to have deeper pieces of information, consider behaviors, preferences, and details that help to identify easier ways to close your next sale.

  3. Tools and systems. The list building you use needs to compliment the tools you have. A mistake that is common among businesses is they “mismatch” their systems with their list building. The result is limited sales prospecting, confusion with information, and issues with the tools details.

  4. Amount of data. The quantity of data you get impacts your process. It changes the price, alters the process of prospecting, and causes the sales team to fluctuate with their work. Identifying what you need first will help you find the right data vendor.

  5. Types of services. Many vendors will provide an “A La Carte,” allowing you to match the types of services you want or need with each vendor. Others will offer an option for full service, allowing you to have a complete set of services for your lead generation needs.
