Alright I know the blue triangle/arrow means traffic is dropping, and the red ones mean traffic has increased, but what does two red ? mean?
Also, what is the time frame used to determine if traffic has increased or decreased?
It means traffic is steady. This is good news. I'm not sure about the time frame, but you can check out your traffic for each hub and find where it is coming from. Much will come right from Hub Pages, while other views will come from Google or other search engines. You will even know how many on your social network sites are reading your stuff.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
