Appearing at a conference is a great boost for your business, especially if you deliver an impactful message. If you can get your business branding out there and associated with the conference, even better. This will help with brand recognition and will make your business more memorable, in connection with the speech or talk you have delivered.
If you run your own conference, your branding can be used everywhere. It will be a great feat for your PR and can help to generate additional, high-value business. Remember though, a conference is a lot of work and you will have to find speakers, a venue, write comms materials for delegates, and generally work hard to ensure it is well attended. If you don’t have the time a resources to dedicate to hosting a conference or if you don’t have enough material at present, speaking at one can be very beneficial also.
