Users with a Google account will have their information integrated among all Google products including Gmail, YouTube, and Picasa. Google has already been collecting this information, but the new policy will allow the company to combine data across all its websites to get a deeper understanding of its user. For example, if you reside in Florida and watch a clip of a Miami Heat game on YouTube, you may see NBA ads appear on your Gmail account. Google will be able to tailor search results based on information given on Gmail, Google +, and YouTube to better understand what users mean when they search common terms like “apple” or “pink.”
“In short, we’ll treat you as a single user across all our products, which will mean a simpler, more intuitive Google experience,” says the official Google blog. The concept is similar to Facebook’s network of games, messages, and apps all under one user log-in.
