![Facebook Ads Will Use Your Web History [UPDATED]](https://helios-i.mashable.com/imagery/archives/03yvdfIa46ekagtHkHg266N/hero-image.fill.size_1248x702.v1647018566.jpg)
Facebook will soon use your activity on other web pages to target ads based on your interests, Financial Times reports. That's potentially a big boon for advertisers, but it won't sit well with privacy advocates.
Note that Facebook already targets ads using information from your profile, and this new system will not track all of your browsing.
Rather, Facebook will offer sharing buttons to interested websites. Readers will be able to click on them to share the links with their Facebook friends via Facebook Connect — just like the buttons you already see on this Mashable article.
Once the user shares a link with his friends, Facebook will assume that person shared it because he or she liked it, so the company will include content from that web page in the data it uses to target ads based on user interest. The ads will appear whenever the user visits the Facebook website.
Facebook will probably announce this new system at the F8 conference on Wednesday. The company is also expected to officially announce its already-revealed to change the words "Become a Fan" to "Like" for brands' pages because it has found that users are more likely to click the latter than the former.
