Hello. I want to buy new domain from namecheap with whois guard, and I'm not sure if adsense allows websties with whois guard. Someone knows?
The fact that I couldn't find a website with whois guard and adsense on scared me off.. and what does the age matters?
That's not entirely true. Things like domain age are taken into account when assessing the site's reputation. But I am not aware of any specific reason not to use private whois.
There was a discussion regarding whether using private whois will negatively affect your SERP, the reason is that you might seem to have something to hide. However, I don't think that is the case as Google itself is a registrar and I think can see through whois guard anyway if they need it to.
