Hello everyone,
Now, I want to buy a new domain and starting SEO for it but I heard that domains with good history ( expired domains ) are easy to do SEO than new domains, it this exact?But the price for them is more expensive. Could you confirm me? thanks
Age does not mean a domain is good for SEO, look up some Google Webmaster Videos on Youtube or relevant articles around the web. Google has stated that they count the age of a website for SEO purposes by the first time they crawled a given site. If you buy a domain and it has a new site on it (or 1 you build), then to Google it is a new site and will count the age accordingly.
What can make a difference as far as SEO is the fact that their might be some residual SEO factors when you buy an old/deleted/dropped/etc. domain. Things like backlinks (although you will probably have to do some work to keep them active & of value), indexed pages, etc.
One thing to also consider with older domains is that not only good will transfer to the new owner, but some bad things might as well.
What is more important to Google would be the length of the current registration (when it expires) as Google see's this as that the site will be around a while and not some "Here today, Gone tomorrow" junk site. Google it, they have said this many times.
I would worry about getting a good domain first, considering other factors like brandability, meaning, etc., before worrying about the age of the domain. If it happens to be an older one you get and there are some residual SEO benefits, then sure, go ahead and get it. However, I wouldn't make domain age a main point in the value of a domain.
Good Luck
