How to select a reliable data provider?

Usually, data quality is evaluated based on factors such as accuracy, completeness, uniformity, and freshness. However, in our experience, there are a few other things that are useful when selecting a reliable data vendor.

Coverage and freshness

The number of data records and locations represent the technical capabilities of the data vendor. However, data freshness is just as important as coverage. If the data provider can keep the data fresh at all times, that also reflects how reliable the provider is.

Refreshing data in a systematic way that brings the most value to the clients requires a lot of experience and capabilities. Refreshing data based on specific priorities and a sophisticated profile qualification logic requires a team that can develop the needed infrastructure and processes to collect and refresh the data this way.

Prompt and transparent communication

Being able to get all the relevant information about data quality, fill rates, data structure, and features mentioned above prior to purchasing data solutions also shows that the data provider is transparent and can be trusted. At Coresignal, we provide information about relevant metrics to our potential clients, and we can guarantee stable data delivery and consistent data structure every time.

Test first
Lastly, it’s essential to test and see if the data you’re getting from the provider meets your business needs and expectations. We encourage you to share what information is needed for you to evaluate our data and we are ready provide the resources that would be most helpful in testing our datasets or APIs.
