Depends on the context, but here are some ideas:

• 👁 (selling attention/eyeballs)
• 📈 (results)
• 💰 (help monetize)
• 📢 (promote/announce)
• 📣
• 📯
• 💬 (get people talking about you)
• 📺 (video ads)
• 💈(real-world example of advertising)

@marckohlbrugge, wow. Thank you so much for your reply with such a great details. I've got idea for different things where I've to assign emojis - and you've come with great answers 👌

I need to thought about the emoji exactly for "Advertise" if it should be 🎯or 📣 in case of that "Advertise" means promoted content.
