On the social network sites including Facebook, there are many annoying advertisements. Some of advertisements are relevant, but most of them are equal to spam.
Since Facebook received many complaints about ads on the site, it plans to tweak its formula for choosing ads to make those much more relevant. If people are interested in the ads, they can click on them or share them with their friend. Oppositely, if they find the ads are really annoying, they can report them or hide them. Facebook will receive feedbacks about the ads and get a user’s personal tastes from both actions.
Moreover, this action of Facebook may risk alienating advertisers. There may be a potential impact of revenue changes.
From my perspective, this is a good idea to tell Facebook people’s preferences. In the future, there should be more relevant ads and less irrelevant ones. However, it is not effective. In most situations, people will skip the ads instead of closing them no matter they are annoying or interesting, because people do not want distract their attention from on-line communication and spend time on closing the ads.
