Rank Tracking & Personalized Search

[bronxpad]

How effective is rank tracking when google tends to deliver personalized search?

I tend to clear out my browser of all info, cookies and cache so I can get the best results but how effective are rank tracking algo's in delivering accurate results. I run various apps and tests and I get different results.

The best way to be close to "real rankings" is to use Chrome with incognito window.

BUt again like you said there are additional factors that it looks are becoming more and more important that you can not reproduce - location, google plus circles and so on.

Cheers.
