DA is such a seductive distraction, isn't it? A number flashing at you from a third-party tool, and suddenly every other signal gets ignored.
Saw this exact pattern with a few brand collaborations we took on after the big spam update a couple of years ago. The root cause almost always came down to one of three things: a backlink profile that looked impressive only on paper but was actually filled with low-quality, non-organic placements-the kind that reek of mass outreach and zero editorial context. Or the page structure was a tangled mess, burying the real content under layers of irrelevant fluff. And for a few others, core web vitals were quietly suffocating the experience-broken scripts, slow loads, a general sense of untrustworthiness that Google reads like a neon sign.
Domain Authority means nothing to Google. It's a vanity number cooked up by third parties, each with their own weighting system that has zero alignment with how Google actually evaluates trust and relevance. You'll get far more actionable insight from public datasets Google is confirmed to use-Search Console data, Core Web Vitals reports, even their own documentation on helpful content.
Hard to offer specific advice without seeing the site, but if you're open to sharing a link privately, happy to take a look with a brand strategist's eye.
