ReCAPTCHA is a third-party service that adds a security measure to your survey to validate that the respondent is human and not a bot.
This is particularly useful for surveys for which you are providing a participation incentive.
We recommend placing the reCAPTCHA action on the first page of your survey, with no other questions, so that you can eliminate any false respondents immediately.
ReCAPTCHA validates if there is a human user based on a cursor movements and clicks. ReCAPTCHA monitors the path where the user moves the mouse to select the displayed checkbox. It additionally has the ability to sense if there is a generically smooth or organically sporadic pattern in a cursor as opposed to being a rigid set of movements directly up and then horizontally over to reach the box. If ReCAPTCHA senses the predicted movement of the cursor as explained in the latter experience, it poses the second test of having to review images. Based on user interaction, ReCAPTCHA may provide a different user experience. For more information on how ReCAPTCHA works, visit Google's ReCAPTCHA resource page.
Click the Action link on the page where you wish to add the ReCAPTCHA. Select reCAPTCHA and replace the default "New ReCAPTCHA" text with the text you would like to display to your respondents along with your reCAPTCHA.

Using reCAPTCHA with Private Domains & Embeds
In order to use reCAPTCHA on surveys that use a private domain or are embedded on your website, you'll need to register the domain with Google's reCATPCHA service.
- If you are using a private domain, you will need to register the domain with Google.
- If you are embedding* your survey on a website, you will need to register that website's domain.
- If you are embedding* a survey that is using a private domain, you will need to register both the private domain, and the domain of the website where the survey is embedded.
To do so, go to https://www.google.com/recaptcha/admin/create. Google will walk you through the setup process*. When you are finished Google will provide you with a Site key and Secret key.
*Alchemer supports the use of only
You will need to supply both the Site and Secret keys to Alchemer (Account Administrator access is required).

- Paste the both Site Key and Secret Key (received from Google) into their respective fields and Save.
