I bought regional domains for a specific sector; I set up some and didn’t set up others. But I realized that feeding and growing subdomains individually is very difficult. For this reason, I designated a main domain and 301 redirected two strong domains to it, and I saw the impact. However, now I have 15 subdomains. If I 301 redirect both the established and unestablished ones to the site, will I experience issues with my main site?
Also, would it make sense to do the following? Would it be more logical to redirect the relevant subdomain to the relevant subpage of the main site?
I need your experience and recommendations on this matter.
Based on the information I have gathered to date, if the site you are redirecting to the main site is empty—meaning it holds no value—I believe it won’t contribute to the main site you are redirecting to.
In my opinion, if you 301 redirect the 15 subdomains you mentioned all at once, you might run into trouble. Perhaps doing it gradually over time would be more effective. I do not have information regarding the number of domains that can be redirected to a single site. If there are others here who have implemented this before, we await their comments.
Finally, in response to your question: “Also, would it make sense to do this? Would it be more logical to redirect the relevant subdomain to the relevant subpage of the main site?”, I would like to cite the article written by Samet as an example. He wrote that for the site he used in his newly launched project, he performed a redirect from a site relevant to the subpage to that subpage, just as you described.
