It’s frustrating when your Domain Authority (DA) drops, but it’s important to know that DA is just one of many factors Google uses to rank websites. A sudden decrease might not always be due to your actions. Changes in DA can be caused by updates to the Moz algorithm, competition gaining better backlinks, or even shifts in your website's SEO health.

While creating quality backlinks is key to improving DA, other activities like optimizing site content, improving page load speed, and enhancing user experience also play a role. For instance, on the Kobalt tools official website, a well-structured, fast, and user-friendly experience could help maintain or boost DA. Focusing on overall SEO health will benefit your site in the long run.
