After 2 succesfull days in Google, site suddenly dissapears

[lieven]

Can any one help my with my site?

I made a little commercial site and have put it online about a week ago.
The site was easily indexed by Google already after 4 days.
When creating the site I have optimized it as good as I could. I can say that I start to have an average knowledge of seo.
Never thit I use any Black Hat seo like hidden text or links.
I have chosen many niche tail keywords for the site and have distributed the keywords wisely over the content in all important places.
The site contains about 5 or 6 reciprocal links.
The problem now is that after only two days the site totally dissapeared in google's rankings. Even when I search for the site's name it won't appear in Google.
On the other hand when I run the command site:www.mysite.com, I get a list of almost any page of the site. So I can conclude the site is still in the index of Google.
Has any one an idea of what caused my site dissapearing from google search results? Did I get penalised, why and what should I do?

Thanks to any one who can help me.

click on your reciprocal links. What sites are they? Do they have page rank? Are they link farms?

If a site you recip link with is penalised or banned, you may get penalized as well.

Also, when you do a "site:" search do it without the "www." This way any sub domains, if any, will show up as well.

from my own experiences it is very common that Google will drop new pages from a site after a few days, if your site is new it will take a bit longer to stay in the index. If the quality of your site is good it should come back within the SERPs.
