If a website with no backlinks and domain authority (DA) of 1 is ranked first, several factors could contribute to it.

Relevance: Your website's content can be an exact match to a user's search query, making it highly relevant.

Low Competition: The keyword or topic you are ranking for has little competition and your site may rank despite having a low DA.

Geographic Targeting: Search results can be influenced by geo-targeting, favoring local or niche websites.

Recency: The site may have recently published content that fits into a trending topic and temporarily boosted its ranking.

User Experience: Your website may offer a good user
experience, fast loading times, and mobile friendliness, which are preferred by search engines.

Overall, backlinks and DA are important ranking factors, but they are not the only ones. Other factors such as relevance, competition, and user experience are important in search engine rankings.

That's intriguing! It could be due to various factors like content relevance or user experience https://copyenglish.com/.

It might just be, purely that the domain name has the area in Australia in the domain name. Sometimes, that alone is enough to get the business onto page one of Google. For example, we have a business, sells fencing. That website has been content marketing, links, on-page SEO but still ranks further down the page, because we don't have the city name in our domain name. Does this help? I would highly recommend hiring a link building SEO agency, that builds links in a white hat way, and only pick an SEO company that builds links using white hat methods, which follows the advice of Google- E-EAT- does this help you?

To start my website with no backlinks and achieve a good Domain Authority (DA) ranking from the beginning requires a strategic approach.
