Ok here goes. Over the past 2 years our traffic and rankings have slowly declined, most importantly, for keywords that we ranked #1 and #2 at for years. With the new Penguin updates this year, we never saw a huge drop but a constant slow loss. My boss has tasked me with cleaning up our bad links and reshaping our link profile so that it is cleaner and more natural. I currently have access to Google Analytics and Webmaster Tools, SEOMoz, and Link Builder. 1)What is the best program or process for identifying bad backlinks? What exactly am I looking for? Too many links from one domain? Links from Low PR or low “Trust URL” sites? I have gotten conflicting information reading about all this on the net, with some saying that too many good links(high PR) can be unnatural without some lower level PR links, so I just want to make sure that I am not asking for links to be removed that we need to create or maintain our link profile. 2)What is the best program or process for viewing our link profile and what exactly am I looking for? What constitutes a healthy link profile after the new google algorithm updates? What is the best way to change it? 3)Where do I start with this task? Remove spammy links first or figure out or profile first and then go after bad links? 4)We have some backlinks that are to our old .aspx that we moved to our new platform 2 years ago, there are quite a few (1000+). Some of these pages were redirected and some the redirects were broken at some point. Is there any residual juice in these backlinks still? Should we fix the broken redirects, or does it do nothing?  My boss says the redirects wont do anything now that google no longer indexes the old pages but other people have said differently. Whats the deal should we still fix the redirects even though the pages are no longer indexed? I really appreciate any advice as basically if we cant get our site and sales turned around, my job is at stake. Our site is www.k9electronics.com if you want to take a look. We just moved hosts so there are some redirect issues and other things going on we know about.
