Whether subdomains effect on the main domain?


Hi @Mohammad. Previous… you say: I should not mix many topics in my blogs. I decided to start a blog with tutorial blog topic, do I need to take a new domain? or I simply put under my previous primary domain so that it becomes tutorial.biluping.com

whether the subdomain will give effect to the main domain? and for search results, whether it will appear together or merged into one outcome under biluping.com


@fadlybiluping I suggest you to use seprate domain for topics that are not related to your main domain blog niche…

Effect of subdomain on main domain

Sub-domains are effected by trust scores and site scores which include content quality of the main domain though for the most part, they operate as separate sites.


Thank you @AmmarAli for your response. My main domain has the topic of the tutorial as well, but I mix it with astronomical topics and some of life’s journey, so I want to separate them.

I plan to put a tutorial topic on tutorial.biluping.com then put the topic of astronomy in astronomi.biluping.com for traffic to continue to flow to the main domain but every blog has its own topic.

I just want: my brand (BiluPing) can be attached, such as news sites that have multiple subdomains to different topics


@fadlybiluping As far as I understand it… it all depends on how those “sub-sites” interact with the “main site”. If hte subs are independant, do not interlink with each other or the main site - then chances are they will be treated independantly. If they link to each other, or to the main site, and the main site links to them - then they will likely be treated as a singular entity, no different than Directories of a single site.

@mybloggertricks thanks for answer. I have read the link you provided but I then getting confused :smile:

there explained that the subdomain with the same theme can be a cannibal in the search results, then what about my blog? subdomain that I want to have a different topic. astronomy and tutorials blog so (probably) not mutually cannibals in search
