Hahaha,
I can't say how many gums I chewed, but I know there were 5 in a pack and now there are 3 left. If you crack this one, you'll see what's wrong with site:
www.yourdomain.com
I start to notice really strange things about Google and new released web pages. Yesterday my page was in Supplemental Index, today It's back to normal search. More than that, I've noticed that Google Sitemaps updated all internal and internal links report today ( after 7+ months of delay ), which happens once in millennium
...
I have a theory, that Google treats new web sites with caution and even small mistake in your page title or contents will trigger Supplemental Result !!! But it may get this page out of there when someone links to it or they'll decide that this page is ok to be shown to public.
What do you think?
