A recent thread regarding my sitemap to Google Webmaster Tools was closed so will start this one with a new question. Initially my current submission reads as: (DNS, Server Connectivity and Robots.txt fetch ALL GREEN), (791 queries with 32,926 impressions - 719 clicks), (13,846 URLs submitted -11,958 URLs indexed), (4226 images submitted - 3280 images indexed) and of this report in URL Errors: 0 server error, 1 Access Denied, 6 Not found. My question regarding the URLs indexed has me wondering....it was actually over 12,000 a few days ago but recently dropped to what it is in this current report and wonder why that is? Is there anything I ought to be paying attention to? This sitemap was actually submitted on or about February 6 (about a month and a half).Of all those images within, I've also tagged a majority with a specific keyword.....
