Domain Authority (DA) growth often depends on time, quality backlinks, and consistent SEO efforts. For example, one of my sites FreeTestAPI, offering free mock APIs for developers, is 1.5 years old with a DA of 13 now. I started with DA 0. This reflects steady progress through I didn't work on valuable content and natural backlink acquisition.

DA is a relative metric, so even with improvements, your score might not change quickly if competitors are also growing. Focus on building high-quality backlinks, improving user engagement, and creating unique resources—over time, these efforts will lead to a stronger DA and better rankings.
