9 Best Data Crowdsourcing Platforms for 2023

Data is the new oil. Today, data powers everything from machine learning models to business intelligence. But actually acquiring quality data can be challenging and expensive. This is where data crowdsourcing provides immense value. By breaking down data tasks and distributing them to a crowd of people, organisations can gather diverse datasets, run large surveys, moderate content and more at scale.

In this post, we look at the 9 leading data crowdsourcing platforms to consider leveraging in 2023 and beyond

What is Data Crowdsourcing?

Data crowdsourcing is a process of collecting data from a large group of people. The data is then typically used to improve a product or service or for research purposes.

Data crowdsourcing can be an effective way to collect large amounts of data quickly and cheaply. There are a number of online crowdsourcing platforms that businesses can use to collect data from a large number of people.

However, there are some potential drawbacks. For example, the quality of the data may be lower than if it was collected by professional researchers. Additionally, the data may be biased if the people who choose to participate in the crowdsourcing project are not representative of the population as a whole.

There are a number of factors to consider when choosing an online crowdsourcing platform, such as the type of data you need, the number of people you need to reach, and the budget you have available. To help you choose the right platform for your business, here are 9 of the top data crowdsourcing platforms:

Best Practices for Crowdsourced Data

Follow these best practices when leveraging crowdsourcing:

  • Provide clear instructions, examples and FAQs for each task.
  • Implement qualification tests or screening to filter high-quality contributors.
  • Build in ongoing QA processes, spot checks and audits.
  • Have a process to quickly address low-quality work.
  • Treat workers ethically and compensate them fairly based on local costs of living.

Key Evaluation Criteria

When selecting a crowdsourcing partner, some key factors to evaluate include:

  • Workforce size and diversity – Larger and more diverse pools offer more scalability.
  • Experience – Domain expertise in specific data tasks needed.
  • Quality – What QA measures are in place to ensure high-quality work?
  • Security – How is data security, access and privacy handled? Is IP consent required in data collection?
  • Workflow – Are workflows customizable and optimised for quality?
  • Platform – Is the platform enterprise-ready and easy to integrate/manage?
  • Support – What customer support and expertise is available?
