When expanding a website, website operators often wonder whether they should use subdomains, directories, or other domains. But what about SEO for subdomains?
Subdomains are independent domains and, from an SEO perspective, have no connection to the root domain, which is why the primary domain does not transfer its link power and trust to the subdomain. Website operators must therefore optimize subdomains individually for keywords and develop their own link marketing strategy for them. One advantage is that the primary domain and other subdomains are not affected by Google’s algorithmic penalty for the subdomain. The same also applies the other way around.
In addition, usually only one result per domain is shown in search results. Subdomains can be used to place additional adverts and thus achieve more clicks.
