I want to know what is happening to blogger subdomain when we are using our own domain. Important question is what will be effect of blogger subdomain in SEO when we are using our own domain? Will the blogger subdomain still act as a influencing factor for SEO? Or search engine skip the masked blogger subdomain and read only the domain we used?
