Craft a query like this: site:yoursite.com

Click Search Blogs

This query will return results only from yoursite.com, and you will then be able to see what content is indexed.

You can speed up this process by notifying Google Blog Search the moment you publish a new post by adding its ping URL to your Update Services:

To find out more about notifying third parties when you post and where to put this URL inside your Admin Dashboard, read this WordPress documentation:

You can also perform a site search query in Google's main search to see all results Google has for your domain instead of just blog post results. Once you start pinging Google Blog Search when you publish new posts, your content will begin to be indexed faster in the main Google search results. Google's main results are influenced by its blog results (and other sources like YouTube and Product Search) as part of Google Universal Search.

If you are concerned about the description of your site (or snippet) provided in Google results, you should find a WordPress plugin that allows you to easily control the content of your META Description tag on each page of your WordPress site.

There's a lot of things going on here. Explore the items I have mentioned here and update your question if something isn't clear.
