2. How is Incidence Rate (IR) calculated? 

Incidence is calculated as a conversion, using the formula (Completes / (Survey Entrants – Quality Terminations)). This conversion calculation most closely reflects how the panels sending to your survey understand project performance.

3. How do I select panels for my survey?

As you enter survey audience qualifications during the set up process, the top right Feasibility and CPI box will populate. PureSpectrum Marketplace offers transparent multi-source supply. View the available panels from the Feasibility drop down for your project before you launch and choose who you want to receive sample from. 

PureSpectrum vets all suppliers to ensure a quality marketplace. In addition, PureScore, PureSpectrum’s proprietary respondent scoring system, assures only high-quality respondents get into your surveys. 

4. Can I change quotas after my survey has launched?

Yes, PureSpectrum Marketplace allows you to manage projects while in field. Manipulate existing quotas, add, delete and modify quota goals all in one place. Survey management has never been this easy. 

5. Can I target by location within a country?

Yes, we offer location targeting options. You can also upload a list of zip or postal codes for more precise fielding and create custom quota groups.

6. How do I set up redirect links for my survey?

Follow the redirect guide found on the “Finalize and Launch” page of the survey set up under “Redirect Links”. You will only need one set of redirects for all Marketplace suppliers. 

The PureSpectrum platform removes the need to email with multiple parties, enables you to consolidate quota tracking and instantly communicates changes with all suppliers so you don’t have to reach out to them directly. 

7. How do I launch a survey?

After implementing your survey link and redirects, test the project for a successful completed session. Following a successful test, decide if you want to turn on any of PureSpectrum’s special features, and launch. Once you launch the project, the integrated panels that you have selected will immediately start sending based on the audience and quotas that you have set up.

8. How can I conduct a tracking study on Marketplace?

Follow the prompts and launch your first wave. For the next wave, you can simply “Clone” the last survey, and adjust the title, completed interview goal and links as necessary.  Supplier allocations can be controlled to keep consistent blend of panels.

9. Can I recontact respondents?

Yes, you are able to recontact respondents. Reach out to your Account Manager to learn more about setting up recontact surveys. 

10. Do you have B2B survey sample?

Yes, you can select from a choice of qualification questions in “Advanced Targeting” to access B2B survey respondents. 

11. Is PureSpectrum deduplicating respondents?

Yes. Before a respondent enters your survey, PureSpectrum uses device fingerprinting, fraud detection and PureScore to deliver only real, unique and quality respondents.  You can also deduplicate respondents from prior PureSpectrum surveys by grouping them on the Finalize page.

PureSpectrum Data Quality

PureSpectrum uses proprietary methodology and machine learning to ensure reliable insights. To learn more, view additional survey FAQs specific to data quality below:

1. What does PureSpectrum do for Data Quality?

As the Marketplace operator, PureSpectrum has responsibility for the quality of the respondents and surveys made available.  All Marketplace panels are interviewed and vetted before commencing API development.  Before being made available to the full Marketplace, new panels send to select accounts in a probationary period.  All respondents pass through rules based deduplication and fraud checks, contributing to our proprietary screen, PureScore.

2. What is PureScore?

PureScore is a comprehensive, advanced Machine Learning driven, scoring system designed to measure individual survey respondent quality on a scale of 0-10. The model finds patterns in the profiles and behaviors of respondents, and the more a respondent deviates from the ideal, the lower their PureScore. Every inconsistency is flagged and penalized, decreasing the respondent’s PureScore.

3. Explain the scale of 0-10.

Respondents with a PureScore of 0-5 are blocked from taking surveys on the platform. Those with a score above 5 are allowed to participate in surveys. As respondents display inconsistent behavior, their scores will decrease. Respondents with a PureScore of 5 and below have exhibited screening inconsistencies and are blocked from taking buyer surveys. However, they will still receive opportunities from suppliers to return to the platform and answer questions on the PureSpectrum screener. This allows  them to demonstrate consistent behavior and build up their score to back above 5.

4. What deduplication efforts does PureSpectrum take? 

By monitoring browser type, operating software, internet connection, device type and settings and unique respondent ID (PSID), the PureSpectrum system can determine if a respondent already took the survey from the same or different panel within the Marketplace.

5. Is the score viewable?

No, this score is not visible.

6. Is there an additional cost to use PureScore?

No, not if you are buying from the Marketplace. PureScore is an added layer of data quality on the PureSpectrum platform included in the sample costs to ensure the quality you deserve. 

7. Is this service only available on the PureSpectrum platform?

Yes, a respondent must pass through PureSpectrum to be scored. They must have a unique PureSpectrum ID (PSID) to receive a PureScore. It is a PureSpectrum proprietary model to ensure respondent quality and consistency.
