Google crawling / 404'ing nonexistent parameter urls in Google Webmaster Tools.
I am using %postname% pretty urls, the post urls are generally good but there are parameters added to the end that I cannot find in my database and are throwing 404's - and would these parameters be creating duplicate content if they were found?
anybody else ? Is this anything that WP-SEO is adding to the mix? I am also using W3TC - ???
Thoughts? After going nuts trying to redirect hundreds of these bad urls I am currently trying blocking them in Google Webmasters (GW) URL Parameters I went from having 0 404's in GW and 0 reported by 404 Redirected (404 Plugin) to currently 326 in GW and nearly 1000 by the 404 Plugin.
