There are two competing priorities that researchers consistently demand:

  • Quality sample that is representative of the target population
  • Delivery you can depend on

Researchers conducting online studies have increasingly adopted marketplaces that utilize multi-sourcing because the methodology delivers on both priorities.



  1.  Increased Representation 

Marketplaces, like PureSpectrum, create a network of panels via APIs that offer representative sample from around the world. APIs offered in marketplaces have created channels for previously untapped, differentiated sources. These connections offer a broader representation of the population making sample marketplaces the dependable resource of supply for researchers. 

“The quality of the data is superb – at the time of fielding, 49% had received at least one dose of the vaccine – right on target with national estimates at the time. I feel very confident in the data. In our opinion, the content of this wave of the tracker is some of the best yet.”

Scott Mayer, Senior Quantitative Analyst at MDRG

  1. Reduced Inherent Bias & Risk 

Sourcing survey respondents from a variety of panels reduces bias inherent to any single provider. Each survey panel has its own recruitment strategy, incentive model, management style, clientele, and offers different demographics. Blending these sources reduces the risk of an outlying source impacting a study. PureSpectrum’s robust panel integrations give researchers the power to choose their panel blend and ensures high-quality data.

  1. Consistent Screening and De-duping

Technology makes deduplication and quality screening a seamless process in a marketplace approach to multi-sourcing. As the quality-first sampling platform, PureSpectrum is leading the industry with the first and only respondent level scoring system, PureScore™. PureScore™ uses advanced machine learning to monitor respondent behavior, score them accordingly, and block those with a low PureScore™ from entering the platform to take surveys.




  1. Timeliness

Where a methodology to increase representation may make data collection a longer process, multi-sourcing condenses it. More sources sending to a study can shorten field time. Data collection timelines shorten with the use of a sample marketplace, allowing researchers to take on more projects.

“With PureSpectrum, we are able to launch a study on Saturday morning, complete fielding by Sunday and deliver results to our clients faster than ever before. The PureSpectrum partnership has helped our company take on more work and grow our client relationships.”

– Hannah P., Research Associate at Consulting Agency

  1. Find Niche Respondents

Finding low incidence target groups can be like looking for a needle in a haystack. Because of the multisource nature of sample marketplaces, PureSpectrum users start with a bigger pool of potential respondents. In addition to having an array of sources, PureSpectrum’s Advanced Targeting feature allows researchers to pre-qualify respondents resulting in a better conversion and helping fill harder-to-reach quotas. 


Researchers know that using multiple sample sources is best practice but finding reliable quality online respondents can be challenging. Sample marketplaces empower insights professionals with better insights by providing both quality and delivery. PureSpectrum’s unique data quality measures, intuitive interface, and extensive field management features make it the complete sample solution.
