How would you introduce/publish your brand new website?

[dan]

I am a website designer, and recently designed a website for a famous person. So when the website is releasing there will be many visitors from Facebook and other social network. I was thinking how can I introduce the website. I mean the text, How should it be? We decided to send the link as a post and with a line about the website and asking people to check that out. But don't know what should I say exactly.
So I know there are many people good at representing and publishing it. So can you write me a line or give me some idea about posting, and releasing this website.

Thanks in advance.

If you know exactly what is the website all about then it won't be hard for you to promote it.
