In an evident effort to drive the growth of its lucrative advertising business, Facebook has recently revealed that it will allow marketers to use the Web browsing habits of its 1.3 billion users to target ads to them.

The move underscores a notable advertising-related change being introduced by Facebook. Though ads have been appearing in the feeds of Facebook users since 2007, not all ads have been of interest to the users, particularly if they have not 'liked' many products.

However, with the ads-related change on the cards, Facebook users will now be shown up ads that will be related to the information they have searched online, even outside of the Facebook social network.

Facebook users will apparently react differently to the mentioned change in the direction of targeted ads --- while some may find targeted ads to be useful; others may feel that the ads are creepy and intrusive. Some users may also feel that Facebook is "overstepping" into their personal zone with targeted ads.

Facebook has, meanwhile, claimed that the targeted ads move is rooted in the fact that people want to see ads which are relevant to their interests; and elaborated its point saying: "Let's say that you're thinking about buying a new TV, and you start researching TVs on the web and in mobile apps. We may show you ads for deals on a TV to help you get the best price or other brands to consider."
