Behavioral Search
Google has always been on the leading edge of search engines and they are fast becoming concerned with EVERYTHING you are doing in efforts to personalize your search experience. This is the dawn of a new search where past behavior modifies the results. If you are signed into any Google account, your Google SERP’s will be tainted with results that best match using, not only your search terms, but also your search history.

How to turn off Personalized Search Results
There is really no permanent way to stop Google from personalizing your search results other than never being logged in when you perform a search! However, if you’re using GMail, Google Calendar, Picasa, etc, you’re more than likely already going to be logged in. So in that case, there are two methods:
1. Add &pws=0 to the end of the URL after you perform the search. So once you perform the search, you’ll have some long URL text in the address bar and you simply need to append the above bold text to the URL. Here’s how mine looks after adding the text. Press Enter and you’ll now get the depersonalized results.
2. The second method is to turn off personalized search simply by logging into your Google Web Search History and disabling it.
The link to your web search history is in the top right hand corner next to your Gmail address.
Once you disable the search history, Google can’t return personalized results because it has nothing to go on if you have disabled the indexing of your web searches.
How can this play a role in search engine optimization?
For many years it was profitable to use a blanket strategy and optimize loose and highly active keywords in efforts to draw the biggest traffic numbers to a site. Those days are fast disappearing. It is important to develop an SEO program that will identify and capitalize from ALL of your target markets. 3-4 keyword searches are common now, whereas just a year or two ago 1 word searches were the most prevalent.
You want your listing to be available for educational purposes, entertainment purposes, as well as commercial purposes. By creating content to identify with each of these markets, you are keeping your site “relevant” and in SEO relevance wins!
