Within the GWT console under URL Parameters there are two settings that I'm not clear on. What is the difference between setting a URL parameter to:
No: Doesn't affect page content
Yes:Changes, reorders...and then picking
No Urlsunder which URLs google bot should crawl?
I am trying to remove all URLs with certain parameters from the index and not sure which setting to choose. I've already submitted a sitemap with the new URLs and I will set up a 301 redirect to the new URLs also, but I think some of our old parameters are causing issues with crawling efficiency and duplicate content so I want to try and clean that up.
