Domain authority (DA) is a metric that indicates how well a website is likely to rank in search engine results. A strong SEO strategy can help improve your domain authority by building high-quality backlinks, optimizing on-page content, and improving technical SEO aspects like site speed and mobile-friendliness. Websites with higher domain authority tend to rank better and attract more organic traffic. Improving DA takes time, but consistent SEO efforts will help establish your site as a trusted source, boosting your overall rankings and visibility.
