Twitter said Wednesday that it has introduced a set of tools that allow  marketers to target ads at mobile users based on a wide range of  criteria, including their operating system, their device, and even if  they're on Wi-Fi.

In a blog post,  Twitter explained how it's expanding the mobile-targeting options it's  giving advertisers. Previously, the company said, it allowed mobile  targeting only by operating system. But now marketers will be able to  direct ads at Twitter users based on which specific version of iOS or  Android they're using, as well as their specific mobile device, and whether they're connecting via Wi-Fi.
Clearly, the idea is that advertisers believe they can get better  conversion rates the more they know about users' individual situations,  and can target ads that are more likely to appeal to, say, iPhone users  than those on Android. Similarly, someone connecting via Wi-Fi is a  different kind of potential customer than someone on the go.
Twitter said telecommunications marketers might, for example, "promote  loyalty and rewards to users on their specific devices, or reach new  prospects on older devices." And, the company is aware that there are  different demographics for different devices and wants to allow  marketers to take advantage of that.
For Twitter, increasing the numbers of tools its advertisers have at  their disposal is a natural and necessary step to take. While that's  been true for some time, it's essential for the company now that it's gone public and will face increasing pressure to turn a profit, something it has never done.
