Hello. I am conducting a project and I am trying to advertise on website. How can I use an English word to describe the activity of marketing, instead of using “Promotion”. Background of this advertisement: We have some clients who have confirmed to join, but we want to attract more. So we want to use a word to fill in the sentence like The ____(promotion) of the project goes successfully.

Thank you in advance!

Sorry if I post in a wrong place.
Has the project started? More information needed.
Thank you for your attention, David.

I have already solved the problem regarding the interpretation of the advertisement.

Thanks again.
