Is it more difficult to promote a previously known brand/name/title?

Question

Search Engine Optimization

I'll try to give an example.
For example, if we take the name Sophie, then we will get an issue about the singer.
Or Bruno. And there are even more well-known brands.
But what if the customer wants exactly this name and no other?
Is it harder to promote this online? Does it matter that the title already has associations with the audience? Or is it a plus? What are the pros and cons of this practice in your opinion, if you have already encountered it?

Answer 1

Marketing is not a battle of brands but a battle of perceptions, you must capture the mind of the client with your name and not be in the shadow of another name. No. 1. The law of marketing says it's better to be first than to be better.
Two brands under the same name cannot be in the mind of the consumer.

Answer 2

Brand owners will tell you (more precisely, your customer) about this. More or less well-known brands are supported by the presence of a trademark.

Answer 3

Well, in the issue you will always be lower than the same Sophie and Bruno.
