Learn French: Une masse de clics va créer le buzz. - A mass of clicks is going to create a buzz.

This is the core rule for collective nouns! With expressions like une masse de or un groupe de followed by a plural noun, the verb can be singular or plural. The singular va emphasizes the collective entity (the mass). The plural vont emphasizes the multitude of individual items (the clicks). Both are grammatically correct.

Is créer le buzz standard French or just internet slang?

Le buzz is an anglicism that has become a standard, everyday term in French for media attention or going viral. Expressions like créer le buzz or faire le buzz are the most natural ways to talk about something going viral online.

Why use une masse de instead of une foule de?

While both mean a large amount, une foule de literally translates to a crowd and is almost always used for people or living things. Because clicks are inanimate, une masse de or un tas de (a bunch of) are much better choices here.

Does the 's' at the end of clics link with the 'v' in va?

No, you do not pronounce the 's' in clics. Even though it is an English loanword, it follows standard French plural rules where the final 's' is silent. Also, you never make a liaison between a plural noun and a verb starting with a consonant like 'v'.
