Domain age plays a role in how well a website is trusted by Google. The more Google trusts a website the more it will consider ranking it highly in a search. Very new websites find it more difficult to achieve stable positions on Google as they haven’t built up that trust. We haven’t seen yet, and it doesn’t look possible for a brand new website to rank for a single word keyphrase such as “hotel”. No matter how many links are built towards a new website it will not compete with these single words for at least 12 months. However long tail keywords and profitable keyphrases are possible with new domains within a month or so, but to compete on a real high level the website would need to be on Google for a minimum 12 months.
