Welcome to the Q&A Forum

Dan, Feel like I'm getting close to wanting to make that switch.  I've deleted quite a few affiliate product pages in hopes of pushing Panda away and so that there won't be as many pages to switch over.  There are many more that I can delete as well. What type of services can you provide to help with a smooth transition to Wordpress? Ed

Totally Agree and Yoast have recently updated this plugin. shiv

Joelhit is completely right about the www and non-www version. You should 301 one of them to the others to resolve the duplicate content issues or alternatively you could go to Google Webmaster Tools and let them know which one is your preferred version. This will only affect your issues for Google though. The first option remains the best. To answer your question, no i do not think the yahoo store would have impacted your rankings so much. Just make sure that you get your 301's setup and that you do not link to http://theheismanwinners.com/index.html but instead to http://theheismanwinners.com/. (Or the www. if you choose this as your preferred domain.) I hope i answered your question. Let me know if anything was unclear.
