Each time, more often, search engines like Google, block checking programs which are commonly used rankings for monitoring and verifying the positions in the rankings. The case of WebPosition has been known for being the first victim to be blocked by Google for millions of automated queries to carry out daily in order to provide updated data and real-time positions. Google prefers to be human and not machines to consult in the search engine because their horizon is the objective of total customization of searches performed by people and programs that automate the tracking of rankings, can not optimize efficient algorithms. Although we must also say that these screening programs are beginning to use human emulation techniques, search engine API keys and others to pass by users who search naturally.
The personalization of search results will be a reality very close and is a major reason why we should not worry about the rankings. Based on a wealth of personal data, search engines to display results different depending on the person conducting the search. Google makes no secret that personalization in searches is one of the most important areas in which they are focusing on now. With tools like iGoogle, the taskbar Google Toolbar, Google Analytics, Google Adsense, their new browser Google Chrome and many more services, Google has a huge amount of data to customize your search results, to be precisely in this that is working.
