It's been a while now that Google no longer allows to track search keywords. The reason is that when you click on a Google Search result, the referrer no longer contains the keyword.
But fortunately, it's always possible to get these essential SEO informations in Google Analytics. There is a little trick to do that.
To be able to see this table in your Google Analytics account, it's quite simple.
The table that interest you is under the sections "Search Traffic > Search Queries".
The key to be able to see this table in your Google Analytics account is a little button hidden under the settings wheel.
You will see a page where you will be able to create a link between your Google Analytics account and your Google Webmaster Tools account.
It's done, you can now read and optimize Google Search queries keywords directly in Google Analytics. Enjoy!
