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.
First, you need to know what content is old. If you have a content inventory, this should be simple. If you don’t, you can use Screaming Frog (free up to 500 URLs) to scrape your blog content and publication dates. Or, if you’re more of a manual person, go into Google Analytics and see which blogs are driving traffic and check when you published them. Tedious, but effective.
To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
