Did You Know about "GCLID" Parameters?

What is Gclid parameter?

• Gclid is a globally unique tracking parameter (Google Click Identifier) used by Google to pass information back and forth between Google AdWords and Google Analytics.
• If you enable URL auto tagging in Google AdWords, Google will append a unique ?gclid parameter on your destination URLs at run-time. 
• Because it is a redirect, you won't see any gclid parameters on your ad words text ad destination url's, but it will show up in your Web server log files.
• Auto tagging was introduced in 2004 and is on by default in any Google AdWords accounts.

GCLID Example:

 "Traffic Sources" feature in Google Analytics to segment your campaigns based on ad text and other PPC-related campaign metrics and dimensions, relies on gclid. A disastrous reaction of Google Adwords and Google Analytics reconciliation is that it executes your pursuit question information. 

Basic information relating to snaps and changes are mis-credited to the catchphrase in your AdWords account that set off your promotion, not the genuine pursuit inquiry that was entered by the searcher.
