The Google search engine algorithm is still indecipherable because it changes its algorithm for every fortnight. You can’t even know what Google is in fifteen days.
Most of its products are free like Gmail, android operating system for mobile users etc.
It had showed how to earn, thousands of dollars, money from a simple blog with no artistic knowledge or technical stuff.
Google Reader is making the users to read the entire web articles in a single place that can collaborate and share their views with others.
Everyone loves Google because it has complete resources for webmaster like analytics, adsenses and for net users with products search (in various forms like images, web, scholar, books etc)
The one downfall of the Google is it sometimes steals your privacy by logging your online actions and movements.
