The best way to improve your website’s authority is to get other authoritative websites in your industry to link to your site. Google looks at the other websites that link back to you as the strongest signal that your website is trustworthy. Google looks at how many backlinks you have and how trustworthy these websites are. Think quality over quantity here. For example, one link from the New York Times will significantly help your website rankings than a link from 50 brand new blogs.
