Eminent domain is a legal term for government seizure of property, not an SEO concept. You're asking about high Domain Authority sites. Domain Authority is Moz's proprietary metric predicting how well a site ranks, scored 1 to 100 on a logarithmic scale. Sites above DA 80 are exceptionally strong; above 90 are elite. Wikipedia sits around DA 95. Major news publishers like The New York Times, BBC, and CBC range from 85 to 95. Government domains (.gov in the US, .gc.ca in Canada) typically score 70–90 and carry extra trust signals because they can't be bought. University sites (.edu, .ca) often hit 70–85. Large social platforms like LinkedIn, Reddit, and YouTube are all DA 90+. Canadian examples: Canada.ca is DA 92, Toronto Star is DA 88, University of Toronto is DA 86. These sites have massive backlink profiles, decades of history, and content that earns links naturally. Getting a contextual link from any DA 80+ source moves the needle, but it's rarely easy or cheap unless you have genuinely newsworthy content or academic research. Domain Authority isn't a Google metric—Google doesn't publish anything equivalent. Moz calculates it by analyzing link profiles, and it correlates with ranking ability but doesn't cause it. A DA 30 site with perfect topical relevance and user signals can outrank a DA 60 site targeting the same keyword if Google's actual algorithm favours it. At Ottawa SEO, we don't chase DA scores for vanity. We chase links from sites that Google already ranks well for keywords adjacent to our clients' topics, whether that's DA 35 or DA 85. A backlink from a DA 45 Canadian trade publication in your niche often outperforms a DA 70 generic directory. Context, editorial placement, and traffic potential matter more than the number. High-DA sites are useful because they signal trust at scale, but relevance and естественность always win over raw metrics.
