Two months ago we registered a non-US domain. 1. Around 6 weeks ago, we have started a sub1.domain.extension with unique content, a site with around 20 pages of quality information. 2. Around 4 weeks ago, we have started a sub2.domain.extension, having nothing related to sub1, with again unique content on another topic. 3. Around 2 weeks ago, we have started a sub3.domain.extension, having nothing related to sub1 or sub2, with again unique content on a completely different topic. These three subdomains do not link to each other. sub3 links to mostly governmental instutions, sites that are trustable, sub1 and sub2 are almost external link free. We have linked to these three sites from a few of our well-established sites, from pages that are related to their topics, so they are links that add value to our well-established sites as well. For all of them, pages got indexed, we started getting some hits through Google, for some medium-level competition keywords, we have even seen them in top 10 results or around that. Then 3 days ago, they have effectively disappeared from search results, for some terms they do not even show up, and for the ones they show up, they are around 200+ ranked results. I can understand that websites need time to show up, and that is my experience from before, they took their times showing up, but had a somewhat consistent flow after that. So I'm curious. Although we started them at different times, they all disappeared at the same. Could it be some sort penalty or filter? If so, what could it be? Thanks in advance for any ideas.
take in considiration that you serps will bounce more since your using a subdomain now, instead of a normal domain.
Hmmm, I remember reading somewhere that Google treats subdomains as seperate domains and not part of the same site. Most typical example is whatever.blogspot.com, do you think google treats them as one site?
One of my competitors started using sub domains and I saw them pop up every now and then but I haven't seen any of there sites in 3 or 4 weeks. Maybe something is going on?
