Subdomains out of sandbox, but not root domain

[nevyan]

I've got a website that has been long time in the google's sandbox, after a numerous attempts to regain its trust I've created some new content and put in a website's subdomain.

Now the situation goes like this:
the new subdomain gets fully indexed and whenever I put new content it is spidered upto 2 days max,

but the main domain is still stuck in the sandbox

I am searching for a reasonable explanation to this.

Hello;

To be spidered, a site must have at least one backlink.
Otherwise the site can be removed fom the index (not blacklisted), i had such an experience.

The sandbox doesn't mean that your site is not in the index.
It mean that your site is as well ranked as it should be.

To index a site in 2 or 3 days you must have a PR6 backling.

So for your main domain, two possibilities :
1 : it is not in the index (due to no backlinks to check enter "www.yourwebsite.com" in Google). Try to have some BL or better one PR6 BL. ot maybe your are blacklisted so try Google reinclusion from Google webmastertools.
2 : Your are really in the sandbox : are you sure. A good way to check it is to change the a,e,i,o,u,y with â,ê,î... letter to see if there is a big difference of rank. If so, then it is sandbox.

Regards.
Antoine.

The root domain gets indexed around 5% and then the indexing stops. Following a reinclusion request some of the root domain results appear as supplemental.
After a while the supplemental flag is cleared on some of them, but there are pages that stay in the supplemental index.

The indexing situation in the subdomain is normal.
