How to cite webpage


I’ve a question. How do I cite a webpage in-text? 

I’m using APA 6th style

I want to cite a Facebook webpage from the Help Centre on Tagging. 

This suggests that the act of tagging is a ritual given that tagging is a special link (“Facebook Help Centre: Tagging,” 2013). 
I want to take out the inverted commas. According to my referencing guide, the inverted commas shouldn’t appear.
