How do I change pages registering as 404 to 200

Question

I have this problem. After relaunching my site: http://www.kgstiles.com, traffic dropped immensely(about 60%). After troubleshooting for a week and a half - losing thousands of dollars off of lost traffic in the process, I found that Google was getting a 404 error at the end of many of my 301 redirects(so it wouldn't index the new pages). Most of of the pages, though, would register in my browser. They registered as a 404 error in Google's index as well as a 404checker. So my first question is: could this be what's causing my loss of traffic? and second: how do I fix it?

I'm desperate! Any help is appreciated!

I'm guessing since you implemented 301 redirects you made some major update to your website. I see you are running WordPress now, did you run a different CMS before? If so one major factor in your traffic loss is the URL structure of your site changing. While 301's pass some link juice they don't pass all of it. The content changing on your pages also affects your rankings. So do you happen to know where your home page and other pages were ranking before you made these changes? If not you can go into Analytics under Traffic sources and compare date from before and after you switched platforms and determine which Traffic Source has caused the loss in traffic, i'm guessing it's organics but you'll find out for sure in Analytics. You can drill down under all sources, direct, referrals, organic etc to get a better picture of where you lost traffic.

Can you post a URL of the old website which is 301'ed to the new page so we can view the redirects headers please.

Thanks
