I am seeing a pretty precipitous drop in search volume traffic (see link). My keyword rankings don't seem to have suffered too much over this period. In fact, my #1 keyword have actually increased slightly in this timeframe. Two questions... Is there some way to assess overall search volume across my tracked keywords (to see if this is just a case of overall searches dropping)? Is there a recommended plan of attack for investigating drops like this - beyond overall search volume, what other data might be important in identifying the cause of this. In short, I'm looking for some logic/structure for how I investigate this, using Moz tools and reports. Thanks. Mark omE1VPc

Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

This is more of a technical question than pure SEO per se, but I am guessing that some folks here may have covered this and so I would appreciate any questions. I am moving from a WordPress.com-based blog (hosted on WordPress) to a WordPress installation on my own server (as suggested by folks in another thread here). As part of this I want to move from the format blog.<mydomain>.com to www.mydomain.com\blog. I have installed WordPress on my server and have imported posts from the hosted site to my own server. How should I manage the transition from first format to the second? I have a bunch of links on Facebook, etc that refer to URLs of the blog..com format so it's important that I redirect.</mydomain> I am running DotNetNuke/WordPress on my own IIS/ASP.Net servers. Thanks. Mark
