  K. S. Bisht: I need your help.
  
  here are page with following urls
  
  example.com/page1.php?tour=London%20Tours%20Packages
  example.com/18-xyzpage.php?tour=Hawai%20Tours%20Packages
  
  I want Google to index these pages but should not index "?tour=London%20Tours%20Packages"
  
  after the URL.
  
  Please let me know what to do for that?

  Toni Anicic: Depends on what's the content behind those parameters. If those parameters purely narrow the selection, I'd use rel canonical to point those versions of the URL to the one without those parameters and additionally properly set parameters handling within Google Webmaster Tools. If it completely changes the data and not just narrows, I'd go with meta noindex.

  PromozSEO: As +Toni Anicic ;said, use rel canonical to point out the main part of the URL you want Google to index.
  You can use Webmaster tool's 'URL Parameters' to let Google handle parameters in your URLs more efficiently
  Additionally add # just before the question mark. Like ;example.com/18-xyzpage.php#?tour=Hawai%20Tours%20Packages, technically Google should not index the portion after the first #.
