If your domain authority has not changed, it means that, according to metrics used by search engines like Google, the overall authority and credibility of your website has remained static. Domain authority is a numerical score that reflects how well a website is likely to rank on search engine results pages. It's influenced by various factors including the quality and quantity of backlinks, content quality, user experience, and more.
If your domain authority hasn't changed, it could be due to several reasons. It's possible that there haven't been significant changes in the factors that influence domain authority, such as the number or quality of backlinks pointing to your site, or the overall quality of your content. It's also worth noting that changes in domain authority can take time to manifest, as they are based on a complex algorithm that considers numerous variables.
To potentially improve your domain authority like I did for Bingsu Machine, consider focusing on high-quality content creation, ensuring a positive user experience on your site, and engaging in ethical and effective link-building strategies. It's important to remember that domain authority is just one of many metrics used by search engines, and while it can be an indicator of a site's overall quality and authority, it's not the only factor considered in search rankings.
