Setting Up Your Audience Profile
To set up your audience, go to the Audience section in the Build Survey area. The page will open on the Audience Profile tab, where you can choose who you want to reach. By default, the Glass Survey Audience will be selected.
Use this default audience unless you plan to bring your own respondents.
If needed, you can apply Inbound Census settings. Inbound Census helps balance your sample by aligning respondent demographics—such as age, gender, or region—with census benchmarks. This ensures your survey data more accurately reflects the overall population. Select any checkboxes for which you’d like Inbound Census balancing applied.
If you’re not using audience quotas, leave the Who Do You Want to Talk To? section set to Natural Fallout.
If you do want to apply quotas, choose Custom Audience instead. This option lets you define and manage specific Audience Quotas for your survey. See more information here.
Pro Tip: Audience details will determine who the survey is sent to and what proportion of different demo groups come to your survey, but quotas can also be applied for ensuring the exact proportions that complete your survey. Use quotas set to 0 for terminating those who are ineligible.
Respondent Quality Settings
The second tab in the Audience area is the Respondent Quality tab. This section allows Glass to ensure that your study receives the highest quality respondents.
Several quality controls are available here:
Bad Respondent Detection — Screens for common bot and spam behaviors, such as duplicate IP usage or other automated response patterns.
Duplicate Detection — Identifies whether a respondent has already completed the survey to prevent multiple submissions.
Pre-Survey Screening Questions — Adds brief questions before the main survey to help detect inattentive or low-quality respondents.
Copy-to-Paste Detection — Flags when respondents paste text into open-ended or free-text fields, a common indicator of low-effort responses.
It is recommended to keep all of these options enabled for most studies. The only exceptions might be specialized research designs, such as CATI (computer-assisted telephone interviewing) or other non-standard quantitative methods where respondents are verified through other means.
Using Your Own Audience
Under the Audience tab, select My Own Audience.
Launch your survey
Live link is provided on the review page prior to launch and appears on the analytics tab once launched. This will be the link you send out to all of your respondents.
Unless a unique id is added (see below), there will not be any way to link back to your original data.
It is recommended that you test the link prior to distributing to respondents.
Including a Unique ID in your Audience
Currently Glass supports the ability to pass one parameter through the URL, a Respondent ID (RID).
Before you send out your survey, add ?RID={external_user_id} to the end of your survey URL.
Enter the RIDs to replace {external_user_id}
Each respondent’s unique RID will be passed through in the raw data, so you can easily identify the respondent.
