Welcome to the Q&A Forum

#1 - I haven't seen a guide that specific, but http://www.seomoz.org/blog/down-and-dirty-write-your-own-url-rewrite should be helpful #2 - you can move whenever you'd like, but if you're worried about Panda, I'd be careful and make sure that all the pages on your site are unique and highly valuable to visitors. Google's got some pretty sophisticated algorithms to figure that stuff out. You might want to try http://www.seomoz.org/blog/replicate-googles-panda-questionnaire-whiteboard-friday You're correct that if you get hit by Panda, having subdomains may help insulate the main domain from the penalty. But long term, you should be aiming for maximum benefit and not just protection. If you do things right, you won't need to worry about Panda.

Hi Vinku, You can find a nice discussion on Raven and Ontolo here - http://www.seomoz.org/q/ontolo-vs-raven-seo-tools Gianluca makes some good points that they are kind of hard to compare because Ontolo focuses only on link building while Raven is an overall campaign tool. Also, all three of your options offer a free trial. Why don't you give them each a shot and see what you think? Tim

I agree with Matthew, I would make to separate sitemaps and submit them both. Don't forget to type up the scripts in the video descriptions!

Hi Vinku, There are three basic ways to handle this. 301 redirect all expired or old pages to the category or subcategory they belong to. This is a great method if the pages get some tweet, shares and external links pointed at them. This method was endorsed a speaker at SES from CareerBuilder, who has a similar issue where job postings always expire. Let all the pages 404 and remove them from your site. Let most pages 404 and 301 selected pages that you know where popular to the category or subcategory page. It depends a lot on the popularity of your site and on the technical capabilities you have. Good luck.
