Hello friends,

I would like Know that What Do you Means domain age?   

Domain age refers to the length of time that a website has been registered and active. Domain age conveys trust to website visitors and to the search engines.

Domain age is an important SEO factor for your Google ranking. Among the hundreds of weighting factors that Google considers in determining how to rank search engine results is the age of your domain — in other words, how long that domain has been around.
