Choosing a speaker by CV is the most common criterion, and the one that fails most often. A speaker with an impeccable track record may not connect with a specific audience — the fit between the speaker's style and the real profile of the room matters as much as the content of the talk.
The format of the talk shapes who you should book
Not every speaker performs equally well in every format. Someone brilliant in a thirty-minute keynote with a fixed script may not work as well in a panel with unscripted questions, and vice versa. Before searching for names, it helps to decide what format the event actually needs — keynote, panel discussion, hands-on workshop — because not every speaker moves comfortably between the three.
Watch the speaker live before booking
A video of a previous talk in a similar format and length to the one needed is the best way to assess whether the style fits. Relying only on references or a preliminary phone call leaves out the most important variable: how the speaker actually performs in front of a room.
Brief the speaker — don't just let them brief you
An external speaker needs to understand the tone of the event, the exact profile of the audience, and what the audience is expected to do with the content afterwards. A brilliant speaker without that context can deliver a technically excellent talk that doesn't connect with the specific room in front of them.
The internal speaker option
An executive or specialist from within the company can be a better choice than an external speaker when what's needed is authenticity rather than spectacle. There's no speaker fee, they already understand the real context of the audience without a briefing, and they create a different kind of connection than a stranger on stage. The trade-off is that they rarely have experience speaking in public at that scale, and usually need coaching beforehand so they don't lose the thread in front of a large group.
Motivational talks: a special case
Motivational talks divide opinion more than any other speaking format — they work very well for some audiences and generate outright rejection in others. Knowing the team's real culture before booking this kind of content avoids the most common mismatch between the speaker's tone and the sensibility of the room.
Put the time limit in writing, not just in conversation
Speakers who run over time are one of the most common problems in event production, and one of the ones that throws off the rest of the programme the most. Setting the exact duration in the contract, with an explicit cut-off warning, keeps a twenty-minute talk from turning into forty and derailing everything scheduled after it. Having someone from the production team near the stage with a visible time-remaining signal is a simple measure almost no speaker objects to when it's raised in advance.
The speaker's language versus the audience's language
For an event with an international or mixed audience, the speaker's language level — and the audience's — determines whether simultaneous interpretation is needed. A speaker with functional but not fluent English can lose important nuance if they aren't used to presenting in that language to large audiences. Assessing this before signing the contract avoids last-minute surprises with the translation budget and with the actual quality of communication.
Prepare the Q&A in advance
Leaving the Q&A completely open and unplanned is risky, especially with speakers who don't know the audience well. Collecting two or three real questions from attendees before the event, and passing them to the speaker ahead of time, avoids awkward silences and leads to more considered answers than a question improvised on the spot. It also works as a safety net if no one steps up to ask a question live.
Cost isn't an indicator of fit
A more expensive speaker doesn't guarantee a better fit with a specific event's audience. It's common to find lesser-known speakers, with tighter fees, who connect better with a technical or sector-specific audience than a generalist media figure. Assessing fit before name recognition avoids overpaying for a result that doesn't match the talk's actual objective. Asking for references from organisers who have worked with that speaker in a similar context usually gives more useful information than any press pack.
The best indicator before booking isn't the speaker's fame. It's whether someone on the organising team has seen them live and can confirm they work with an audience like the one they're about to face.
