Hi. I am still very confused whether to take this step or not.
I have 3 blogs each on a subdomain, with the main domain empty. 4 years ago I opened the site which was on the main site, then 2 years ago I separated it into 3 blogs and put teach on a subdomain, and the main domain remained empty.
Now, I am thinking of moving the primary blog from the subdomain to the main domain, by "giving wordpress its own directory" namely, I will set the Site address to the root directory and copy the htaccess and index.php to the root.
In terms of SEO, is that fine? Will the subdomain still function, and will this not affect the SEO?
The point I am doing this is that I read that subdomains do not rank well (compared to main domains), so I wanted to take advantage of the empty main domain and drive traffic into it (I am planning to turn it into a bigger site in the future, which aggregates posts from all other blogs on the subdomains).
So, any info will be appreciated.
