Google site search is tool that enables you to search sites instead whole Internet. For a long time Google is not just a search engine. I don`t even know how to define Google. Never mind. Behind minimalist design of search engine page is a series of extremely useful tools and features.
Yes, how many times you saw some article on some website but you don`t remember article title. Then you type search terms to Google site search, one after another in order to find article, but with no luck. There is a way when you know on which site you saw that article.
This means, that you can search particular website instead of whole Internet.
Go to www.google.com and type, for instance site:it-tutorials.net google. Basically syntax is site:domain search term (Slide 1).
You now see, that shown search originate form it-tutorials.net and that all link have google as keyword. On page, still can be shown contextual ads. Whit this you can focus search to one website.
I hope this tutorial was informative to you. I will try to show you few more Google tricks in next few tutorials.
