Types of Data Collection Services: Which Do You Need?
Before choosing a provider, it is critical to understand which category of service fits your goals. Most “data collection” searches fall into three buckets:
- Managed Data Services (Agencies): Companies like Zilo act as an extension of your team. You provide the guidelines; they manage the workforce, quality control, and delivery. This is essential for high-stakes AI training data.
- Panel & Survey Platforms: Tools like SurveyMonkey allow you to design a survey and “buy” responses from a pool of users. You manage the questions; they provide the people.
- Crowdsourcing Marketplaces: Platforms like Amazon MTurk offer a raw workforce. You post small tasks (HITs), and anonymous workers complete them. This is the cheapest option but requires heavy quality filtering.

Frequently Asked Questions (FAQ)
What is a data collection service?
A data collection service is a third-party company or platform that gathers quantitative or qualitative information for businesses. These can range from automated web scraping tools and survey panels to managed agencies that manually annotate data for AI training.
How much do data collection services cost?
Costs vary significantly by method. Crowdsourcing platforms (like MTurk) may cost pennies per task. Consumer survey panels (like SurveyMonkey) typically charge $1–$5 per response. Specialized B2B recruitment or managed AI annotation services (like Zilo) are often project-based and command higher rates due to the expertise required.
What is the difference between data collection and data mining?
Data collection is the process of gathering raw information from various sources (surveys, web scraping, observations). Data mining happens after collection; it is the process of analyzing that large set of data to discover patterns, anomalies, and correlations.
Which data collection method is best for AI?
For AI and Machine Learning, managed data annotation services are typically best. AI models require highly accurate, structured ground truth data (labeled images, transcribed audio) which usually requires human-in-the-loop verification rather than simple automated scraping.
