As on December 4th 2009, Google extended its Personalized Search system for Non-registered users. Earlier this option was available to registered users, only when they had Web History enabled on their Google Accounts. Google Search now displays all users with personalized results – including those who are not registered. Google saves a cookie contains information about Search Results for the last 180 days. On the basis of the file search versed in internet user preferences, adjusting the results to him. User will know, he is seeing Customized search results when a “View customizations” link will appear on the top right of the search results page. Clicking the link will let user see how Google have customized results and will also allow user to turn off this type of customization.
What does it mean to SEO? No Doubt Google is making it more and more tough for SEO professionals to tweak its results.
Now how can we know the behavior of different users? You have a “cookie” Google to do that, but what SEO professionals should do?
Definitely its gonna be biggest challenge for SEO. In my opinion, now Social Networks will play most vital role, as this is the only method available to us to remain closer with community. There are over 100 Community networks, and for me, it is already biggest source of traffic. Become more and more visible to community, and definately your brand will be preffered in their personalized searches.
