So this new project that i am working on is a redesigned CMS site using Wordpress (php based). Before i started on the project they made a few major updates that include:
- Changed from ID based URLS to SEO friendly URLS
- Added multiple languages in directories
- Due to the new languages they wanted to have the previous home page, www.domain.com, redirect to the proper language based on their IP address. Currently they are using a 301 redirect through a php header. So if i was visiting the site from my hometown of Cleveland, Ohio and i type www.domain.com into the browser. I would automatically redirect to www.domain.com/en and i would have the option to switch languages if needed.
The issue:
When i first added their site into SEOMoz the crawl returned a large amount of 302 redirects coming from their old homepage www.domain.com. So i took a look at the header calls using IE's webmaster tools and Firebug in Firefox. In both profilers it showed the same problem.
- Before the 301 header redirect there was a 302 redirect called first
- When viewing the response header it mentioned an x-pingback of some file that didn't even exist on the site: www.domain.com/xmlrpc.php
This is obviously a huge issue because any link value from the old homepage will be lost due to the 302 not passing the value. I have tried search the almighty Google for help but it has gotten me no where. I have a hunch it is something to do with Wordpress but that is based on nothing but my gut. Any help is greatly appreciated.
I got to get that 302 gone or changed to a 301
