  Collin Davis: +Tim Quin ; Unfortunately no technique is fool proof and gives you 100% accurate results.
  
  However here are some techniques that will remove most of the personalization.
  1. Go into the incognito mode on Google Chrome. It removes most personalizations - ;https://support.google.com/chrome/answer/95464?hl=en
  2. Append &pws=0 after your search query URL in Google search results. ;
  3. One other technique which I have found useful is to use the Google Ad Preview - ;https://adwords.google.com/d/AdPreview/?__u=1000000000&__c=1000000000
  
  Hope that helps :)

  W.E. Jonk: Quite some time ago one of our moderators ask a similar question [1]. ;
  
  However there is only one way to get ranking position because scraping the SERP's [2] is against the terms and conditions of Google, which is in Google's Webmaster Tools under "search traffic" --> "search queries". In the table you find the "avarage position" for a particular keyword [3].

  Frank Rodríguez: +Tim Quin as Mr jonk suggests , webmasters tool

  William Gomes: Hi +Tim Quin ;I've created a video for you on how I do this. ;How to Accurately Track Search Engine Rankings
  
  Thanks to +Collin Davis ;& +W.E. Jonk ;for your inputs too!
• 
  W.E. Jonk: +William Gomes ;great video reply! Indeed the way to do those things is through proxy server (you don't need a VPN). You probably also need a captcha solver. Or how do you deal with the captcha?
  
  However I am pretty sure G called these actions black-hat and that is why I directed to GWT, which isn't that great (I know).
• 
  William Gomes: Oh I make the searches very very slooow... So no captchas ever appear and as it changes its location every 4 minutes it would be very very hard to track my individual activity.
• 
  William Gomes: Here are the settings I use: http://img802.imageshack.us/img802/8506/twm2.png
  
  Also I think VPN's are more reliable than proxies as I can select the exact location I want. For example I am not in London but some of my clients are and so are their customers so I can reliably select a VPN there which I think is good. ;
• 
  W.E. Jonk: +William Gomes ;VPN's can act like a proxy server but they don't have to (if you are using OpenVPN it depends on the settings, not sure about other implementations). VPN's are used to act like a local machine (in a nutshell). Proxy servers aren't VPN's they only route your traffic through another IP (in a nutshell). In this case you only need a proxy server and you can achieve that with VPN solutions like OpenVPN.
  
  So using a VPN by itself doesn't make it "more reliable", it is just an option within a VPN solution. Makes sense? ;
• 
  William Gomes: But with OpenVPN you can't choose the locations you want can you? Or at least its limited? I've tried it before without good results that was years ago though.
• 
  Stephen Watts: Ultimately you need to invest in a software or saas solution for rank tracking to handle hundreds of keywords for multiple clients. Moz is a good start but won't scale. I'd suggest Advanced Web Rankings with Trusted Proxies to handle really unlimited keywords its just a matter of buying enough proxies to fit your needs
• 
  Dave Elliott: I use moz but disagree with its ranks constantly. You can do it manually but that takes ages.  ;+Collin Davis ;is right in what he says but use mozbar(chrome or firefox) and it has a "serp overlay" which with a bit of configuring will let you do a fully non personalised search, or a non-personalised with a location fairly quickly. If you are measuring lots of key phrases though then it is still ridiculously time consuming.

  Tim Quin: Thanks so much for your comments guys you've been really helpful.
• 
  Ranu Jain: Rank Checker is also worth trying. Of course, you won't get the accurate results but can try. Simply clear the cache, set "&gl=us" in the search and then run the tool. ;
  
  I have tried it and cross checked with my people sitting in US. It is worth a shot.
