This article explains how to halt to a greater extent than than 1 someone providing a answer to a questionnaire that y'all receive got made using Google Forms.
use Google Forms to lay a survey or questionnaire into your blog.
Sometimes when y'all lay a shape into a blog-post, it is OK for people to respond to a greater extent than than in 1 lawsuit - too Forms fifty-fifty has an choice to submit around other entry immediately.
But sometimes it's not.
For example, if y'all are researching a item topic, y'all belike desire each person's persuasion to count once, rather than having an enthusiastic someone (effectively a human bot) meet their responses many times too so bias your results.
Google Forms has at nowadays a characteristic which lets you require everyone who wants to submit results to your survey to last logged in to a Google account, and too then alone lets each Google Account submit the shape once.
Job done! You volition at nowadays alone instruct 1 respond from each person. Read 1 to detect out to a greater extent than effects of doing this, too around to a greater extent than issues that y'all postulate to consider.
People who desire to respond to your shape must log-in using a Google describe organisation human relationship earlier they tin rank notice see the form.
The person's electronic mail address isn't recorded inward the results canvass but Forms won't receive got around other entry from the same Google Account.
If someone tries to consummate your Google Form again, a alert is shown, proverb "You've already responded. You tin rank notice alone fill upwards out this shape once. Try contacting the possessor of the shape if y'all intend this is a mistake."
However if y'all plow the choice off too and then on again, it does recollect which Google accounts receive got responded during the fourth dimension that the choice was off, too stops them from responding again.
My recommendation is that y'all should only role the Allow alone 1 answer per user choice if it really makes sense for your shape to last similar this. Otherwise, exit it turned off.
If your shape is fifty-fifty slightly complicated, it is a adept thought to bear witness it (perhaps from a individual bear witness blog) earlier y'all start using it.

Understanding Google accounts
Sometimes when y'all lay a shape into a blog-post, it is OK for people to respond to a greater extent than than in 1 lawsuit - too Forms fifty-fifty has an choice to submit around other entry immediately.
But sometimes it's not.

How to halt people submitting a Google Form to a greater extent than than once
Follow these steps to halt the same user entering a shape multiple times:- Edit the form.

Job done! You volition at nowadays alone instruct 1 respond from each person. Read 1 to detect out to a greater extent than effects of doing this, too around to a greater extent than issues that y'all postulate to consider.
The number of the one-response-per-user checkbox
When this choice is turned in, each answer is guaranteed to come upwards from a unique Google-account.People who desire to respond to your shape must log-in using a Google describe organisation human relationship earlier they tin rank notice see the form.
The person's electronic mail address isn't recorded inward the results canvass but Forms won't receive got around other entry from the same Google Account.

Is the Google describe organisation human relationship refer available to the form-owner?
No. Google Forms checks the currently-logged-in describe organisation human relationship against the listing of accounts that receive got submitted a response, but it does non display the account-names anywhere inward the shape results page.Disadvantages of this approach
- People who practice non receive got Google Account cannot role your form.
- People who are skeptical close linking their electronic mail address amongst their shape entry may last unwilling to respond - no affair how y'all attempt to re-assure them that y'all don't see it.
- Other's may intend that y'all receive got their electronic mail address, too so instruct annoyed if y'all inquire for it on your form.
- People who receive got multiple Google Accounts tin rank notice however respond multiple times: a unmarried someone tin rank notice command many unlike Google accounts, too could (if they were sufficiently evil / motivated) sign out too inward in 1 lawsuit again using each 1 to submit multiple results.
Are people who responded earlier the choice was turned on counted?
No: Google alone tracks users who consummate your shape after the "Allow alone 1 answer per user" choice is get-go turned on. If y'all plow it on for an existing form, people volition however receive got one more lead a opportunity to respond.However if y'all plow the choice off too and then on again, it does recollect which Google accounts receive got responded during the fourth dimension that the choice was off, too stops them from responding again.
Some other things to consider
Is it actually necessary
Some people may plow this choice on because it seems similar the correct thing to do, fifty-fifty if it actually doesn't non affair if someone entered to a greater extent than than 1 response. This could annoy around visitors - for example, someone who completes your questionnaire today, too and then remembers afterwards on that at that spot is something else they would similar to say.My recommendation is that y'all should only role the Allow alone 1 answer per user choice if it really makes sense for your shape to last similar this. Otherwise, exit it turned off.
Don't permit it halt YOU from testing your form
However if "Allow alone 1 answer per user" is turned on, too then y'all volition alone last able to meet 1 answer yourself.
The solution to this is to:
- Leave the choice off land y'all are testing your form
- Only plow it on in 1 lawsuit again exactly earlier y'all install the shape it into your blog.
Other ways to guarantee unique responses
If y'all determine that allowing alone 1 answer per Google describe organisation human relationship is non a adept approach for your form, too then y'all may desire to consider other ways of ensuring that each someone alone participates once. For example:- Ask each someone to meet their electronic mail address on the form, too alone receive got results from unique addresses. (But practice recollect that y'all cannot last certainly that the addresses are associated amongst the people who provided them.)
- Make completing the shape "inviation only" too electronic mail respondents a unique code that they receive got to input, too then don't convey describe organisation human relationship of whatsoever responses that don't receive got a valid code: y'all may postulate to enlist help from a neutral tertiary political party to help amongst this, if y'all desire respondents to believe that their input inward anonymous.
- If your shape is made amongst a Google Apps user-account, rather than a criterion Google account, too then y'all receive got an choice to boundary a Google Form to alone receive got responses from users who are inward your domain - too if y'all practice this, the responses-sheet records the person's username every bit well.
So inward this case, y'all could only kind past times user-name, too exit our responses where the 1 user-name responded to a greater extent than than once.
