This is always the struggle. To implement it is not like promote it. Making the product publicly visible and known is actually the harder part.

Be consistent, try on multiple places, be active, make good site, good videos, good training, talk to people, listen what they say. Post it in reddit, write articles in places like here, dev.to, medium, explain how you did it, why, what you learned...

Cases where somebody implements something and it becomes viral for a one night sleep are so rare, that I am not really sure that they actually exists ;)
