Mla citations?

im doing a paper on sigmund freud, and was told to use the mla style. i researched in-text citations for web pages with no pg number or author, and they said to just put the title's name in brackets. however, all of my internet sources have the same title: sigmund freud! how can i in-text cite this while a) sticking to the format and b) distinguishing b/w sources?? thanks!
