What would you consider an old site, 1, 2, 5, 10 years e.t.c? I ask this because as we all know older sites rank better... Well surely there has to be a line drawn somewhere because say in 20 years time somebody builds a great site in my same niche, my site will already be 23 years old compared to his not even one year old site. So does this mean I will always have the edge on him?? I ask this again because there are some sites in my niche that are 5-10 years older than mine. Its hard to catch up with them but one of these days I will. But surely if this older site rule sticks then the kids of tomorrow won't have a chance competing with our websites of today....? Just a thought.
Domain age is only one factor of many in the Google algorithm (there are probably a hundred). Newer sites beat older sites all the time. Having the keyword in the domain is currently more important than domain age (after the initial sandbox). Backlinks from trusted sites trumps everything else. What Google uses today will change (they tweak the algorithm more than once a day, on average). It's possible domain age won't even be used at some point. Build the best site and promote it - guessing about what the future holds isn't productive.
I am observing domain age is becoming less of an factor these days. Even aged authority sites can lose out to some newer domains when they rely on their old trophies too long.
yes domain age is one of the factor according to google algorithm, but beleve me if you have quality work and right technique in seo you can get the good ranking.
