What Is a Slido Poll? The Mechanic, the Survey and the Rules
A Slido poll is a single audience question that a host launches inside a Slido event, and participants answer it on their own devices after joining with an event code. Slido itself is a Q&A and polling tool for meetings, webinars and conferences; its polls run one question at a time, while surveys bundle several questions together. Results update in real time for everyone watching unless the host hides them, and the host decides when voting opens and when it closes.

What is Slido poll: the mechanism
The phrase what is Slido poll points at a small, concrete mechanism rather than a mystery. Slido is a Q&A and polling tool that sits inside meetings, webinars and conferences, and a Slido poll is one question the host pushes to the audience's own devices. Participants join an event with a code, the host activates a poll, everyone taps an answer on a phone or laptop, and the tally climbs on the shared screen while the room watches. Nothing in that flow is hidden from the host, and that matters when you get to what the rules catch and what they remove.
Two words carry most of the confusion. A poll in Slido is a single question launched on its own; a survey bundles several poll questions into one form that participants fill in together. Both live inside the same event, both are built and controlled from the host's panel, and both use the same join code. So the honest answer to what is Slido poll has two layers: the question itself, and the event that carries it.
How Slido polls work in the room
For a participant, the flow is short. You enter the event code, the active poll appears on your device, you pick an answer, and your response registers immediately. Slido's own guidance describes the default as one vote per participant for each poll, unless the host has switched on multiple responses. That single default shapes everything else: every control the host holds, from email verification to closing the poll, exists to protect or manage it.
Closing works differently from deleting. When the host locks voting, attendees still see the poll on the present screen but cannot send or change anything, and the results stay displayed until the poll is deactivated. The question what is Slido poll usually gets answered fastest in the room itself: watch one run from activation to tally and the mechanism explains itself.
- The question and its answer options, appearing on the device once the host activates the poll.
- A live tally that updates in real time, unless the host has chosen to hide the results.
- A locked poll after closing, still visible on screen but no longer accepting answers or changes.
How does Slido survey work
A Slido survey answers a different need from a poll: instead of one question at one moment, it gathers several poll questions in a single interaction. Slido's community guidance says surveys allow you to ask multiple poll questions at the same time, and suggests them before or after a meeting to learn about attendees' expectations or experiences. Building one is deliberately plain. You click the + Add new button, select the Survey option, and give it a name. If a poll already exists, it can be turned into a survey from the My interactions panel.
From there the survey grows question by question: select + Add first question, then keep going with + Add another question until the set is complete. Slido says surveys begin saving automatically once two poll questions have been added, so a long build does not depend on a save button. Starting a survey works like starting any other poll, with one difference that matters: because it holds multiple questions, launching it presents all of them to participants at once. Results come back the same restrained way. If you want the room to see them, they display one poll at a time, in Present mode and participant mode alike. For anyone whose first contact is the phrase what is Slido poll, the survey is the part that looks least like a poll and most like a form.
One vote or many: what the host controls
The default in Slido is one vote per participant for each poll, and the host decides whether to keep it. If the default stays, the tool leans on honesty, and Slido's own community guidance admits as much when it explains the verification options. Those options are the practical answer to the obvious follow-up. On Professional or higher plans, the host can restrict participant access by verifying each user through email, and each email address then receives a single unique entry code. Google sign-on or a company's SAML login works as an alternative, which ties participation to identities the organiser already controls.
This is also where the question what is Slido poll, asked with suspicion about repeat voting, gets its honest shape: the default rule is a promise, and the higher plans turn it into a check. Nothing on the entry tier behaves like a lock on identity. Hosts who need one person, one answer know which tier that requirement lives on, and participants know the code they typed does real work only when verification is switched on.
What the rules allow and what they remove
Slido's acceptable use rules ask participants to follow the organiser's ground rules and to stay inside ordinary legal lines on privacy, impersonation and similar matters. Notably, the published terms do not carry a clause aimed specifically at paid or incentivised votes on a poll; they reach such behaviour through the general requirements to follow the organiser's instructions and not to use the service in a way that harms it. So the question what is Slido poll, asked by an organiser planning a contest or a staff vote, has a rules answer with a gap in it: enforcement runs through broad obligations, not a named anti-manipulation rule.
The hooks that do exist are concrete. For a breach of its authorised-use obligations, Slido can edit or remove a user's data, terminate that user's access with immediate effect, or cancel accounts outright. Alongside that, Slido or the organiser can stop content from appearing on the screen, and Slido can go as far as blocking a participant's access to the service.
- Removal or editing of a user's data when the authorised-use terms are breached.
- Termination of a user's access to the service, with immediate effect.
- Blocking of a participant's access, or removal of content before it reaches the screen.
What nobody can promise you
Two promises get made about audience polls that nobody can keep, and this page refuses both. Nobody can promise that manipulated activity on a Slido poll will always be spotted, and nobody can promise it will never be. What actually exists is a set of visible things: the live counter and results the host watches in real time, the one-vote default, email verification and single sign-on on higher plans, and terms that let Slido or the organiser remove content, terminate access or cancel accounts. Those are the facts a suspicious organiser can act on.
Notice what is missing from that list. There is no published per-device technical lock on the entry tier, and the terms do not name incentivised voting on a poll as its own offence. A host who needs a verifiable one-person-one-answer event builds it on a plan with identity checks rather than hoping the free default behaves like one.
Where the results land
Once a participant answers, the results update in real time on participant devices, unless the host has chosen to hide them. Hiding is not cosmetic. In a quiz or a sensitive staff question, a visible tally changes how the next person answers, so the hide switch is part of how a poll keeps its honesty. After voting closes, the results remain displayed until the host deactivates the poll, which means the room can keep seeing the outcome while the meeting moves on.
Surveys report differently again: in Present and participant modes, survey results can only be displayed one poll at a time. That restriction surprises hosts who expect a single summary screen, so plan the wrap-up around walking through the questions one by one. And if someone arrives late still asking what is Slido poll, the answer is already on the screen: a live tally of a question they can still answer before the host closes it.
| Aspect | Poll | Survey |
|---|---|---|
| Questions per interaction | One, launched alone | Several, presented together |
| How it starts | The host activates it | Starting shows all questions at once |
| Saving | Saved as part of the event | Automatic once two questions exist |
| Results on screen | Live tally, hideable | One poll at a time |
| Identity control | One vote per participant by default | Same default, email verification on higher plans |
How to do it
-
Add a new interaction
Open your Slido event and click the + Add new button, then select the Survey option from what appears.
-
Give the survey a name
Give it a name so you can find it again among the event's interactions when it is time to start.
-
Build the question list
Select + Add first question to begin, then continue adding as many questions as you need with the + Add another question button.
-
Let the saving happen
After two poll questions are in place, the survey begins saving automatically, so a long build does not depend on a save button.
-
Start it and read it back
Launch the survey as you would any poll; all questions reach participants at once, and results display one poll at a time afterwards.
Common questions
What is Slido poll?
A Slido poll is a single audience question a host launches inside a Slido event; the phrase what is Slido poll usually means exactly that interaction. Participants join the event with a code, answer on their own devices, and the tally updates live. Slido itself is a Q&A and polling tool for meetings, webinars and conferences, and the poll is its one-question interaction, with the survey as the multi-question version.
How does Slido polling work?
Slido polling runs through an event code: the host creates a poll, activates it, and everyone who joined answers on a phone or laptop. Results update in real time on participant devices unless the host chooses to hide them. When the host closes voting, attendees can no longer send or change answers, and the poll stays visible with its results until it is deactivated.
What are Slido polls?
Slido polls are the single-question interactions inside a Slido event, launched one at a time by the host. Their multi-question cousin is the survey, which presents several poll questions together. Both are built and controlled from the host's panel, and both run under the same event code participants use to join.
How do Slido polls work?
Slido polls work under the host's control from start to finish. The host writes the question, decides whether the one-vote-per-person default stays or multiple responses are allowed, activates the poll for the room, and can hide the live tally. On Professional or higher plans the host can also require email verification, so each email address receives one unique entry code.
How does Slido survey work?
A Slido survey bundles several poll questions into one interaction, and starting it presents every question to participants at the same time. You build it with the + Add new button, add questions one by one, and the survey begins saving automatically after two questions. Results can be shown one poll at a time, before or after a meeting.

This page explains how Slido's polls and surveys work and stops where its documents stop. It carries no prices and no purchase links for any poll service. It will not teach ways around the one-vote default, will not name any vote seller, and never claims that manipulated activity goes unnoticed or that any outcome is guaranteed. The question what is Slido poll gets its plain answer here; what the rules cannot do gets said just as plainly.
X prohibits coordinating with or compensating others to inflate engagement metrics, and it names Polls among the features covered. The Pet Industry Business Awards name the consequence in their own contest: a business may be investigated, lose votes or be disqualified on reasonable evidence of purchased votes. No seller can stop an organiser from doing that.
Slido says it is alerted when an event gets an unusually high number of votes in a very short time, and Crowdsignal says its built-in measures detect patterns of potentially abusive voting. Ordinary participation arrives spread across the voting window, from different people at different moments. Nothing on this site is a method for getting a vote past a check, and a vote that a tool blocks does not count.
Organiser rules differ: the RSPCA Pet of the Year Awards allow extra votes through donations on their official mechanism, while OpenTable Australia treats a vote cast in exchange for money or a reward as null and void. Both are contest rules, not statutes, and whether payment is lawful where you live is a question for a lawyer. Orders are refused for any contest whose rules ban paid votes, and for political ballots.
Votes ordered for a poll that never appear on its count are refunded after the poll closes. A refund never covers an organiser's decision: Localsearch may void all votes for a disqualified nominee, and Mentimeter says a user whose access it cancels under its Acceptable Use Policy is owed no refund or compensation. No result is promised.
