Welcome to the Q&A Forum

I'd like to find an SEO free-lancer to review WikiTree.com and give me ongoing advice. My first instinct would be to go through oDesk, but I know I want someone who is tuned-in to this community and uses SEOmoz's tools. Advice or recommendations? Thanks!

If a site removes thousands of pages in one day, without any redirects, is there reason to think Google will penalize the site for this? I have thousands of subcategory index pages. I've figured out a way to reduce the number, but it won't be easy to put in redirects for the ones I'm deleting. They will just disappear. There's no link juice issue. These pages are only linked internally, and indexed in Google. Nobody else links to them. Does anyone think it would be better to remove the pages gradually over time instead of all at once? Thanks!
