Help with Webmaster stats

Hey guys, anyone have any thoughts on what's going on here. My sites also has dropped 10 or so places since this started, although that could be panda. I have added content, checked robot text all seems to be fine. The only thing I can think I tried back then was installing bulletproof plugin which changes the access file somehow, thought I set all them back to default. Anyone experienced this?

Is your url format changed? did you see any drop on indexed links count? Some time these type of mistake happens when updating your cms or any mods/plugins. The original pages of your website may go deindexed, when duplicate pages start indexing on google. try to use rel="canonical" on all your pages.

Thanks for the reply, as far as I can see everything you mentioned is fine, im using genesis and have not changed any of the settings apart from trying out that bulletproof plugin. Indexing seems to be ok according to WMT.

Check the source are the any meta robots tags?

Is there anything blocking in robots.txt?

Check the webmaster tools verification tag is still in place.

In WmT you can request google to fetch a page, spot check some pages on your site to ensure google can get to them.
