What are the disadvantages of making a site for a AdSense idea in a subdomain rather than a domain ? like if u have yahoo.com and u want start a site for mail. so you use mail.yahoo.com not getting a new domain like mail.com for the new site this would effect AdSense earnings or are there disadvantages ? even from SEO pointof view.
No difference at all.. I have subdomains that make double the money some regular domains do. I have subdomains with page rank 7 and domains with page rank 3, you get the picture. Subdomain is treated as an actual domain. Peace,
From SEO point of view: there is a small disadvantage that some directories do not accept subdomains. Regarding adsense there is no difference between subdomains and domains.
My domain is health9000.com... I want to start separate sites but I don't want to register new domains for each site (I think it's a waste of money) Which is better for adsense? http://recipes.health9000.com or http://www.recipes.health9000.com PS. I have wildcard DNS domains (domain is pointing to a dedicated IP, using external DNS nameservers, it's not using the default CPanel DNS config). http://www.recipes.health9000.com will load http://www.health9000.com/index.php, on index.php I have: if (getenv("HTTP_HOST")=="www.recipes.health9000.com" then: header redirect HTTP 301 to: http://www.recipes.health9000.com/recipes/index.php
For SEO purposes, having subdomains which link to the main domain can help somewhat. It might also mean a slight, slight boost to have the specific keyword as part of the domain. For adsense however, no effect.
