Branding homepage seo inquiry

Hello, I'm currently trying to solve a particular problem, but I'm asking you because there's no progress. I'm currently using a lot of methods to expose our website branding website. We're currently experiencing problems here.

First problem: It is indexed, but when searching by name or homepage name, it is not exposed at all or other pages are exposed. For example, the contact page and introduction page are exposed, and the main homepage is not exposed

Second problem: When searching the example domain com, the same issue as the first problem occurs.

I don't want answers like upload high quality content.
