Advertisers may also deliver ads based on a user's suspected geography through geotargeting. A user's IP address communicates some geographic information (at minimum, the user's country or general region). The geographic information from an IP can be supplemented and refined with other proxies or information to narrow the range of possible locations.[28] For example, with mobile devices, advertisers can sometimes use a phone's GPS receiver or the location of nearby mobile towers.[29] Cookies and other persistent data on a user's machine may provide help narrowing a user's location further.[28]
Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs. 
We recommend enabling messaging on your page to make it as easy as possible for your fans to reach out to you -- but only do so if you have the time to monitor and respond to your messages. Facebook Pages now have a section that indicates how quickly a brand responds to messages, so if you don’t want that section saying that you’re slow to answer, you might just want to skip enabling that feature.
And while you’re at it -- don’t create an additional public, “professional” profile associated with your business. For example, I already have a personal profile on Facebook that I largely keep private; the practice I’m talking about would be if I created a second, public one under the name “AmandaZW HubSpot,” or something along those lines. People usually do that to connect with professional contacts on Facebook, without letting them see personal photos or other posts. But the fact of the matter is that creating more than one personal account goes against Facebook's terms of service.
