Google Will Not Show Search Queries in Analytics or Any of Other Web Analytics Services While Signed into Google.com

Google Search Query Will Not Shown to Your Analytics, If A User Came Through Google Search Engine While Log on to Google

For users privacy point of view Google is going to change http://www.Google.com to https://www.Google.com (SSL) (making Google search more secure) for signed in users of Google.com and If a user came through any of search query (Organic Search) while logon to Google.com then all web analytics services, including Google Analytics, will continue to recognize the visit as Google "organic" search, but will no longer report the query terms that the user searched on to reach your site. But If a user came through CPC (Google Ads) then you can track this.

Google is Making Search More Secure

For Example: Someone is logged on to Google.com (Lets say signed in through Gmail.com, YouTube.com or any of other services of Google.com) and then If that person is using www.Google.com for searching any query then his or her default Google search engine will be https://www.Google.com (SSL) and If that signed person came to my website through "SEO Tips" then I can not know someone came to my website with this "SEO Tips" query while I am using Google Analytics or any of other Analytics tools like Statcounter.com, Sitemeter.com, Histats.com or any of other traffic analyzer tool.

I think it will affect only a minority of search traffic for your website, But It may complex for SEO Professionals to track some of their important Google organic queries.
