Welcome to the Q&A Forum

Hey guys, My background is more in marketing aspect of SEO and I'm afraid my technical knowledge is not where it should be. I'm confused about how to find out whether a site is splitting link juice by having to many domains(?) that are not redirected properly.  Am I asking that right?  How do you figure that out?  And, once you know, do you just go to the ones that are not redirecting and add a 301?  Where is the best place to add a 301? I know there's a difference in the eyes of the search engines between, say, example.com and www.example.com and probably other forms, correct? I'm not a programmer or IT specialist, I'm a marketing consultant, but I feel like I'm really missing it when it comes to understanding all this stuff (looking at HTTP headers, using GWT, reading source code, etc) and am not sure the best way to learn it effectively so I can be sure I'm not missing something when consulting with clients. Help? Please? Thanks, David
