Getting leads is the first and foremost step if you want to make sales. There’s no way around it. 

Sales and marketing today are built around the amount and the quality of data you have. A large number of leads allows you to make a lot of calls or send many emails. It is the data quality, though, that determines the level of effectiveness of your campaigns. Still, many B2B marketing and sales professionals are reluctant to use a B2B database.

Conducting a manual search for any numbers and email addresses of potential leads on the internet is time-consuming and highly inefficient. The best way to get a large pile of leads fast is to use a good lead provider

How do you choose the best source of leads? This article compares prices, features, ease of use, as well as help and support, and provides a list of 19 best leads providers. Take a look and choose the one that suits your needs well.

A B2B Marketing Database - What Is It?

A B2B database is a collection of contact information of prospects. It serves as an important tool for building and improving customer engagement. The main focus of a B2B database is the firmographic data of your target group. Firmographics are descriptive attributes of organizations and companies used to segment and target potential prospects. 

A good B2B data provider will enable you to connect not only to the right companies but also to the right people within them - those who might be interested in your offer and/or those who have already been searching for what you sell or provide. Moreover, the best data providers keep an eye on the changes in the market trends and your target audience’s preferences. They also maintain the customer base up-to-date and become a bridge, between the prospects’ needs and what you offer.

Having accurate and up-to-date contact information plays a huge role in targeting the right people at the right organizations that meet your ICPs. It also allows your sales team to find new connections, personalize messages according to the data they have, and saves time otherwise wasted on calling wrong numbers and updating the CMR.

The main difference between different lead providers is the origin of the databases they use.
