I have a Wordpress site with about 3,000 pages and 1,000 of those are no value/duplicate content and drive no traffic. They are blog posts each with a single image and permalinks like example.com/post1, example.com/post2 etc. I've started by deleting pages and 301 redirecting to relevant pages that actually have content. Is deleting and 301 redirecting the best route? Is 1,000 to many 301 redirects? Should I just delete the pages that aren't really relevant to anything else? Anything else I should know about deleting all of these pages? Any help would be great!

I have a wordpress site with about 3,000 posts and over 1,000 tags. All of the tag archives are currently indexed in Google and I don't want them to be. I just set the meta robots to no-index all the tag archives and was wondering how long it will take til they're out of the search engines? Since there are close to 1,500 of these and they are duplicate content it would be nice to have them gone asap. I noticed Webmaster Tools allows me to resubmit my site to index if my site has changed significantly... should I try that?? Any other advice would be greatly appreciated!
