Matt Cutts, Google’s Head of Webspam, says that once a site is more than two or three months old, domain age shouldn’t make a difference.
Why is it the case then that older sites rank higher in search?
The solution is simple.As long as you’re doing ‘good SEO,’ and producing high quality content on a regular basis, an older site will naturally attain more authority and trust over time.
Domain age itself doesn’t make a difference or help SEO, but the natural lifespan of an older domain should give these sites an advantage if there has been a long term strategy in place. If you’re just starting your website, keep this in mind and ensure you’re ready to play the ‘long game.’
