How can I give more relevance to the title in search results in SharePoint?

In the page, you could edit the page and edit the search result web part to modify the search result.
And in the site, we can go to site settings->search to modify the search.
You could access and modify the search in SharePoint admin center like the picture below.

Title
field is the primary search file for SharePoint Search results. I believe it's specifically the defaultTitle
field rather than any field named "Title" in your list. – KGlasier Jan 17 at 17:19
