Facebook announced Wednesday that Custom Audiences, the ad product that allows marketers to import their own contact lists for targeting, will be available to all advertisers worldwide by the end of November.
Facebook alerted advertisers in a Facebook for Business blog post:
Previously available only through Facebook’s Power Editor tool, today’s announcement means marketers will be able to use Custom Audiences in any Facebook ad interface. Small businesses in particular will now be able to use their current customer lists to reach people on Facebook. And, for the first time, businesses can use MailChimp lists with Custom Audiences.
Getting started with Custom Audiences is simple — just upload customer info like email addresses or phone numbers. Once contacts have been uploaded, you can target matched users with ads for your site, Facebook Page or mobile app.
Starting today, Custom Audiences will start rolling out in all ad interfaces for a limited number of U.S. advertisers. Facebook will start rolling Custom Audiences out globally next week, with all advertisers having the capability by the end of November.

Facebook has created a new way for businesses and developers to target ads to users who have taken an action on Facebook or in an app within a more specific time range.
Facebook is testing a new feature called “Lookalike Audiences” that helps advertisers target users similar to those in their Custom Audience databases, a spokesperson from the company tells us. Advertisers in the beta have seen lower costs per action than with traditional targeting options.
Lookalike Audiences could be a powerful new targeting opportunity that helps advertisers achieve their goals and makes ads more relevant for users. CEO Mark Zuckerberg alluded to this type of innovation on the company’s fourth quarter earnings call last week.
Lookalike Audiences would allow businesses to reach users who aren’t in their database but who are similar to those that are, based on the type of Facebook data that advertisers can currently target against. This algorithmic approach could be more effective than having advertisers select their own demographic and interest-based targeting. Facebook tells us that an online travel site saw 70 percent lower costs per action using Lookalike Audiences, and an online shopping site experienced 56 percent lower CPA and 94 percent lower costs per checkout.
