Problems with SEO

I have a SPA application and a page called “Anúncio” that redirects the user to a specific ad on the index page, as my app is a SPA and the ad details page is a reusable element in the index.

This “Anúncio” page is dynamic of the Anúncio type

Any tips for improving the SEO of this “Anúncio” page?

I’m also having a problem with the bubble domain being ranked first than the custom domain, as in the screenshots below:
