Listen, man, DA is a slow, brutal climb for any new site, tbh. Your 8-month-old domain is still pretty much in the Google Sandbox—it takes a solid year, maybe more, for Google to fully trust ya.
DA itself is just a third-party metric, but the real key is Topical Authority. Stop chasing just links and focus on building out huge content clusters to prove your site is the ultimate expert on your niche. This E-E-A-T stuff is what Google really looks for to speed up that trust factor, even when the DA score looks sad.
