If you are planning to create your own business and strive to ensure that your project has visibility in the search engine, I recommend that you purchase a domain right now and post at least minimal content related to your business topic on it.
The age of the domain played and plays a key role in website promotion, especially in highly competitive and high-frequency niches.
The algorithms of search engines are constantly changing, and currently simply specifying relevant headlines with keywords on pages is no longer so relevant. Moreover, there are completely different algorithmic approaches for commercial topics now.
Mechanisms confirming the usefulness of a resource and its uniqueness, including the age of the domain, are becoming increasingly important. These factors are key and will always contribute over time to increasing the credibility of your site in a particular topic and on the Internet in general.
From practice, I can say that it is currently quite difficult to bring new (fresh) domain names to search results, even in the TOP 50 for high-frequency (HF) and highly competitive (VK) queries, even though the content on the site is unique.
