Individual Blog Post Disappeared In Google Search

[ericw2k]

Hello,

Today I have notice a very weird issue of my blog. All the posts done before 2012 are fully searchable on Google. However, all the post done in 2012 are not searchable on Google.

Back in July when I last checked my blog, there was no such an issue like this and it appears it happened all of a sudden.

My individual post used to be on the first page of google search result but now google only show pages, categories & tags instead my individual post.

Can anyone give a clue how would this happen?thanks a million

Without being able to *pop the hood* on your site or your code it's hard to tell but first check to make sure you aren't blocking pages with robots.txt and/or htaccess and/or malformed canonical tags and/or a meta noindex tag. Next check to see that you haven't been scraped and outranked with your own content.

What happens when you search for an exact match of your new page titles?
