Hi Moz,
I recently migrated my website with the help of an SEO company using 301 redirects. The reason for the move was to change our CMS from .aspx to Drupal/Wordpress. The homepage (www.shiftins.com) and the blog (www.shiftins.com/blog) were the only two pages that kept the same url. Everything else was redirected. It's been about two months since the redirects were completed and traffic has dropped off about 90%. I'm starting to worry that something was not done properly and my traffic may never return.
The process for the redirects seem correct when I checked the work the SEO company did. All pages were duplicated, redirected to individual pages, then the old pages were de-indexed. Are there any insights the community can provide? Please help!
