1 : First an foremost, you should have a pretty good idea of what you want your intro to be before even starting to make the bot.

2 : Make your bot's PERSONALITY come through in the intro (by the way they talk, act, or present themselves, for example).

3 : If your character's from a specific story, make sure it's PLOT ACCURATE. I'd recommend taking an already existing scene and modifying it so that it makes an interesting chat. (Of course, you can modify the plot if it's for an AU.)

3 : Make the intro gender NEUTRAL, so that more people can chat with it.

5 : A good image for your bot will make more people use it. (Contrasted image, zoomed on the face).

6 : Add a catchy 'subtitle'. (Preferably short, but still describing the situation)

7 : Add basic infos about the bot in the 'description' (or even the 'character definition' if you're up for it!)

8 : Most importantly, have fun!

...I hoped this helped anyone. Goodbye, fellow reader ★
