Roles explained

Keynote, MC, Moderator, Panellist: Who Does What

A keynote is not a plenary, an MC is not a host, and almost nobody sells panellists. Here is what each role on your programme actually does, and which ones you can buy.

Conference programmes use about nine different words for people who talk at events, and they are not interchangeable. Book the wrong one and you get someone who does a different job from the one you needed.

This is the guide to which is which, what each costs, and which ones you can actually buy.

Why it is called a keynote

The word comes from music. A keynote was the first note of a scale, the one that fixes which key a piece is in, from the late 1600s. Musicians now mostly call it the tonic.

By 1763 it was being used figuratively: the idea sounded at the start that everything afterwards relates back to. The phrase "keynote address" arrived in 1905.

That history is the actual job description, and it is more useful than any modern definition. A keynote is not just the biggest speaker on the programme. It is the one that sets the note everything else is tuned to. If your keynote could be moved to Tuesday afternoon without anything else changing, you have booked a plenary session and called it a keynote.

The nine roles

Role What they do On stage for Can you book one
Keynote speaker Sets the theme of the whole event. Usually opens it, sometimes closes it 30 to 60 minutes Yes, this is the main product
Plenary speaker Speaks to everyone at once, in a session with no competing streams 30 to 45 minutes Yes, same market as keynotes
Guest speaker A general term for anyone invited to speak. Carries no seniority Varies Yes
Motivational speaker A keynote whose purpose is lift rather than information 45 to 60 minutes Yes, the most-sold category
MC or emcee Runs the running order. Introduces, links, keeps time, handles the room when things slip The whole event Yes
Host Same job as an MC, different word. Often used when the person is a broadcaster The whole event Yes
Moderator or facilitator Runs a discussion. Asks the questions, keeps panellists to time, stops one person dominating One session Yes
Panellist Sits on a panel and answers One session, 45 to 60 minutes Rarely. See below
After-dinner speaker Entertains a fed and watered audience. Closer to comedy than to content 20 to 40 minutes Yes, in some countries only

Keynote versus the words people confuse it with

Keynote versus plenary. A plenary is defined by the room, not the content: everybody is in it because nothing else is running. A keynote is defined by its job, which is setting the theme. Most keynotes are plenaries. Not all plenaries are keynotes.

Keynote versus MC. Completely different jobs. The keynote delivers one prepared talk and leaves. The MC is there all day, holds the programme together, and mostly improvises. Good MCs are rarer than good keynotes and an event survives a mediocre keynote far better than a mediocre MC.

Keynote versus moderator. A moderator asks rather than tells. The skill is drawing other people out and staying invisible. A great keynote speaker is often a poor moderator, because the instinct that makes them good on stage alone is the instinct to fill silence.

Keynote versus panellist. A panellist is one voice among several and does not control the session. Panels are cheap to fill and hard to make good.

Keynote versus guest speaker. "Guest speaker" is a neutral term with no rank attached. If someone offers you a guest speaker slot, ask how long, who else is on, and whether the room will be full.

Keynote versus opening remarks. Opening remarks are usually five minutes from your chief executive or the local mayor. They are housekeeping and welcome. They are not a keynote, and putting them in the keynote slot on the programme confuses everybody including the speaker.

Keynote versus guest of honour. A guest of honour is being recognised rather than hired. They may say a few words. Dignity is the point, not content.

Keynote versus motivational speaker. A distinction about purpose. A keynote informs and frames. A motivational talk lifts. Plenty of people do both, and 64 of the 145 organisations in this directory sell "motivational" as a category, which makes it the single most-listed speaker type.

Resource person. Worth knowing if you book in Asia. It means an invited subject expert brought in to inform a seminar or training session, and it is common in Philippine, Indian and academic programmes. It is closer to a trainer than to a keynote.

What bureaus actually sell

Definitions are one thing. What the market will actually sell you is another, and this is where the directory's own data is more useful than a dictionary.

2 of 145 bureaus sell panellists.

Panels are the most common format at conferences and almost nobody sells the people who sit on them.

That is not an oversight. Panellists are normally found rather than bought: your sponsors, your customers, a friendly academic, someone from the association. The person you should consider paying for is the moderator, because a good one turns four disconnected people into an actual conversation, and 16 bureaus here will sell you one.

If your budget is tight and your programme has a panel on it, that is the trade worth making. Spend on the moderator, source the panellists yourself.

The words change by country

This is the part that catches people booking outside their home market. The roles exist everywhere. The words used to sell them do not.

Role AU NZ UK IE US CA SG
MC or emcee 31/70 8/11 1/20 3/8 1/18 1/11 2/7
After-dinner 4/70 4/11 10/20 3/8 0/18 0/11 0/7
Host 8/70 1/11 6/20 3/8 2/18 1/11 0/7
Moderator 6/70 1/11 5/20 1/8 0/18 1/11 2/7
Awards host 0/70 0/11 5/20 1/8 0/18 0/11 0/7

Three things fall out of that table.

Australasia buys MCs. Britain does not. Forty-four percent of Australian bureaus and 73 percent of New Zealand ones list MCs or emcees. In Britain the figure is one bureau in twenty. The job still exists there, it is just sold as "host", "compere" or "awards host" instead. Search a British bureau for an MC and you will find very little. Search for a host and you will find plenty.

After-dinner speaking is a British and Irish institution that does not exist in North America. Half of British bureaus sell it, and 38 percent of Irish ones. Not one American or Canadian bureau in this directory offers the category at all. If you are running a gala dinner in Toronto and want the British after-dinner format, you will have to describe it rather than name it.

Awards hosting is almost purely British. Five UK bureaus and one Irish one sell it. Nowhere else does.

The practical upshot: when you book across a border, describe the job rather than naming the role. "Someone to run the running order all day and keep it to time" travels. "MC" does not.

What each role costs

Here is the honest answer: the bureaus that publish fee guidance price the speaker, not the role.

JLA's five bands in Britain, All American Speakers' budget filters, Speakers Spotlight's four tiers in Canada and Speaker Solutions' euro ladder in Ireland are all attached to individual people. None of them publishes a separate rate for MC work against keynote work. Our fee guide sets out what those ladders actually say.

What that means in practice is that you are buying a person's day, not a task. Two things follow:

An MC usually costs more than a keynote from the same person. A keynote is an hour on site. MC work is the whole day, including the rehearsal, the running order meeting and the bits where something goes wrong. More of the day is gone, so the number is usually higher.

A moderator usually costs less. It is one session, and the preparation is briefing rather than writing.

Neither of those is published anywhere, so treat them as what to expect rather than what to quote. Ask for the number.

Fee, honorarium or expenses

Three words for money, and they mean different things.

A fee is a commercial price for professional work. It is negotiable, it comes with an invoice, and the speaker is running a business.

An honorarium is a token payment where a fee would be inappropriate: an academic, a public official, a community figure, someone whose employer forbids them taking commercial work. It is usually a fraction of a market fee, and offering an honorarium to a professional speaker reads as not understanding what they do.

Expenses are travel, accommodation and meals. They are separate from both, and whether they sit inside or outside the quoted number is the single most common source of a nasty surprise. Ask.

If you are approaching a professional speaker, use the word fee. If you are approaching a researcher or a public servant, ask what their institution allows before you name a figure at all.

How many of these do you need

For most one-day conferences: one MC or host for the whole day, one keynote to open, possibly a second to close, a moderator for each panel, and panellists you find yourself.

The mistake worth avoiding is spending the whole budget on a single big keynote name and leaving the day to be held together by a volunteer with a clipboard. The keynote is 45 minutes. The MC is the other seven hours, and the audience judges the event on how it felt overall.

If you have to choose, a good MC and a solid keynote beats a famous keynote and no MC.

Where these numbers come from

The role counts, the country table and the finding that 2 of 145 bureaus sell panellists all come from this directory's own data, taken from the speaker categories each organisation publishes on its own site, checked in September 2026. A bureau is counted as selling a role when it lists that role as a category, so the figures track what is advertised rather than what is booked.

The etymology of "keynote" is from standard dictionary sources: the musical sense dates to the late 1600s, the figurative sense to 1763, and "keynote address" to 1905.

The cost observations about MC and moderator work are not published by any organisation in this directory and are described as expectations rather than quoted figures. Where nothing is published, this guide says so.

Nobody pays to appear in this directory. The underlying data is free to use with attribution, as JSON or as plain markdown.

In summary

A keynote speaker sets the theme of an event; a plenary speaker simply addresses everyone; an MC runs the running order; a moderator runs a discussion; and a panellist sits on one. Of 145 speaker bureaus verified across seven countries, 58 sell keynote speakers, 47 sell MCs or emcees, 21 sell hosts, 21 sell after-dinner speakers, 16 sell moderators or facilitators, and only 2 sell panellists, because panellists are normally found by the organiser rather than booked. The vocabulary is regional: 44 percent of Australian bureaus sell MCs against 5 percent of British ones, while half of British bureaus sell after-dinner speakers and no American or Canadian bureau does. Published fee ladders price the speaker, not the role. Verified September 2026 by Speakers Bureaus Directory.
