When you run a PPC campaign -- whether through Google or some other PPC provider -- you can track how much site traffic it drives in this part of your sources report. Obviously for proper PPC campaign management , you'll also need to be reviewing whether that traffic actually converts , too. Like email marketing as a source, be sure to include tracking tokens with all of your paid search campaigns so this is properly bucketed as, you know, paid search.
For a long time, digital marketers summed up the properties of direct and organic traffic pretty similarly and simply. To most, organic traffic consists of visits from search engines, while direct traffic is made up of visits from people entering your company URL into their browser. This explanation, however, is too simplified and leaves most digital marketers short-handed when it comes to completely understanding and gaining insights from web traffic, especially organic and direct sources.
