I have a blog about blogging. When I search something about my content on Google I see my articles on first or second page. But 4 days aga something happened. I didn't do anything, I didn't change my blog's (I use WordPress) options. I can't see my pages in Google search results. May be 16th or 30th pages you know.
I don't copy the content from other sites, I didn't banned. When I look to Google Webmaster Tools, everything ok. For example for "x" keyword I am at 5th place. But when I search "x" I can't see my site at 5th place.
Is it temporary? If it isn't how can I fix it? (by the way sorry for my English)
