Searchable on google engine

Hello there,

I have the last version of wordpress. I have domain too…
But problem is, my site is not aveable on google search.

I try to use “Google Webmaster Tools”, and now I can find my site using google search – only web domain. There is no adionalty text, like “Welcome to my site”, or “My site is for”… just url of my domain.
There is anothere problem, it can’t find any “Sitelinks” on google webmaster.

Do I need to use wordpress plugin? Or my template is problem?

thanks
