Is my site indexed by Google ?

A lot of people ask their selfs or ask other this question: was my site indexed by google can i find it in google ?? Well the answer is pretty simple all you have to do is to go on www.google.com and type site:yourwebsite.com <-- If your site will show up at the results that means google has indexed it.
But how long does it take ?
For the 4 domains I mentioned before it took from 4 to 8 days, but don't expect good ranking at the beggining.
