It will be my first conference talk, and I am nervous :)<p>I don't know how to structure my talk, how to practice etc. I think I need to write a script of all the things I want to say then build the slide to support that script. Much like writing a blog post, or how many youtubers create videos. Is that a good approach?
Depends on the scale of the presentation and venue and how technical the talk and topic.<p>One generally helpful tips is to learn details about the conference venue early, the more you know about the presentation format, the better you can prepare.<p>Try and discover if there's a teleprompters or a second display output setup to provide notes, a script and/or a preview of the presentation.
Understand if you'll stand behind your laptop, have a remote to control it, or a pointer for the screen, and consider the implications of these constraints. What if you want to show a website but you don't have a mouse to close back out of it, or one video in your presentation is particularly loud/quiet and you can't quickly adjust volume down or up enough.<p>Even little things like setting expected aspect ratio or maximum resolution can smooth out the process of plugging in devices or properly displaying a slide/demo.
If you can't get this from the hosts, try finding videos/slides from prior conferences to get a reference and review the standard production value and audience level of understanding.
Here's a good talk:
