I might be overreacting but I just need to know. I registered a new site about 5 days ago. This site is a sub domain. The primary domain has been active for a few years now and is ranking fine in google. I previously had created some content for my new sub domain site and added it to the new site accordingly as well as finishing off my landing page. Once everything was done and set to go, I submitted my (Login To See Link) just to get my landing page indexed (and I would just let my content pages naturally index). The day after it was indexed and could be seen in google. Then the following day it disappeared. Even if I do site:domain Its still gone it has been de-indexed. Why? N.B I don't have a webmasters account. I also have another sub domain which is ranking fine. There are no links pointing to my new site.
