Event awareness upgrade and covering a large audience ???

Expanding event's awareness and large audience outreach ???

raising/increasing event awareness and reaching as large an audience as possible

The increase of the event recognizability and the large audience cover

I don't like - reaching as large an audience as possible

Then how about just REACHING A LARGE AUDIENCE (?)

Andrey basically said what YOU said above - but idiomatically 😉

Maybe yes, but I am more inclined towards this option:
Increasing event awareness and covering a large audience :)

Not the best inclination, Sasha: https://books.google.com/ngrams/graph?content=reaching+a+large+audience%2C+covering+a+large+audience&year_start=1800&year_end=2008&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Creaching%20a%20large%20audience%3B%2Cc0

alright, alright, you convinced me :) you're perfectionist Uliy :)

I’m not a perfectionist - correct language is correct language. Do you want guesses, or do you want real English?

I want to know as much as you know :)

Then look at Andrey’s translation again - it’s perfect))

Andrey, you should post your translation!

Спасибо, Улий, за оценку

What’s right is right!
